Rotator Cuff Injuries









Introduction

Epidemiology


Age





  • Rotator cuff pathology can be seen in a vast array of age groups, from the young athletes to sedentary, geriatric patients.



Sport





  • Sports associated with rotator cuff pathology include overhead sports (such as throwing sports, tennis and volleyball), weightlifting, and swimming.



Important Definitions





  • Primary outlet impingement/impingement syndrome : Pain and inflammation in the subacromial space as a result of the rotator cuff impinging against the undersurface of the acromion, coracoacromial ligament, and undersurface of the acromioclavicular joint.



  • Secondary impingement : Pain and inflammation in the rotator cuff and subacromial space due to an inability to keep the humeral head centered, thus causing altered humeral mechanics and compression on rotator cuff. It is usually seen in younger patients who may have glenohumeral laxity or instability and often have poor scapular control. It can also be associated with weakness of the rotator cuff.



  • Internal impingement : Repetitive contact of the greater tuberosity and articular surface of the posterior rotator cuff on the posterosuperior glenoid in the abducted, externally rotated position. It is usually seen in throwers and can result in partial articular sided rotator cuff tears and posterosuperior glenoid labral tears. It can be associated with subtle glenohumeral instability, posterior capsular tightness and internal rotation deficits, and scapular dyskinesia.



  • Glenohumeral internal rotation deficit (GIRD) : Usually seen in pitchers and athletes in overhead sports (tennis) and is defined as less than 25° of internal rotation or a total arc or motion 25° less than the contralateral shoulder (total arc of motion, both internal and external rotation, should be equal between shoulders, with the throwing shoulder having more external rotation with correspondingly less internal rotation).



Pathophysiology


Intrinsic Factors


I. Primary outlet impingement/impingement syndrome




  • Tendon degeneration



  • Hypovascular zone in the supraspinatus tendon



  • Posterior capsular tightness



  • Acromial and coracoacromial arch morphology (association of rotator cuff pathology and bony excrescences from the undersurface of the acromion) ( Figure 6-1 )




    FIGURE 6-1


    Type 3 acromion with a large bony excrescence from the undersurface of the acromion.



  • Kinematic abnormalities



  • Subacromial bursitis



  • Acromioclavicular arthrosis



  • Overuse syndrome



  • Os acromiale



  • Suprascapular neuropathy



  • Cervical degeneration/cervical radiculopathy

II. Internal impingement


  • Excessive external rotation



  • Tight posterior capsule, leading to loss of internal rotation and a posterosuperior shift of the humeral head with humeral elevation.



  • Subtle anteroinferior shoulder instability

III. Secondary impingement


  • Glenohumeral instability and laxity



  • Rotator cuff weakness



  • Scapular stabilizer muscle weakness with scapular dyskinesia

Clinical Presentation


History


I. Primary outlet impingement/impingement syndrome




  • Painful overhead motion



  • Grinding, catching and popping in the subacromial space with rotational and overhead motion



  • Weakness, which may be caused by pain or can be due to rotator cuff tearing



  • Night pain (very common complaint in patients with a rotator cuff tear)



  • Posterior capsular tightness is common

II. Internal impingement


  • Usually seen in throwers or athletes that put their shoulders in the abducted externally rotated position repetitively



  • Pain in the abducted, externally rotated (ABER) position, relieved with a posterior directed force on the humerus (Jobe relocation test).



  • Possible complaints of catching and grinding due to labral tearing



  • Complaints of weakness and easy fatigue



  • Thrower may notice decreased velocity

III. Secondary impingement


  • Painful overhead motion



  • Can present with grinding, catching, and popping in the subacromial space caused by subacromial bursitis



  • Complaints of weakness and easy fatigue



  • “Dead arm” symptoms with throwing



  • Possible complaints of shoulder subluxation



  • Poor scapular control with scapular dyskinesia and often winging of the scapula when lowering the arm from overhead

  • 1.

    Abnormal findings:




    • Painful arc (Neer and Hawkins impingement signs)



    • Posterior capsular tightness

    • Pain with rotator cuff strength testing, particularly resisted external rotation



    • Weakness of the external rotators can be seen in patients with significant partial tearing of the infraspinatus

    Pertinent normal findings:




    • Usually with intact and normal strength



    • Normal motor and sensory exam



    • Normal and asymptomatic biceps function



    • Complete and symmetric range of motion



    • Normal and asymptomatic cervical range of motion




Imaging





  • Imaging of the shoulder is always done and starts with radiographs in all patients, regardless of the presumed diagnosis



  • X-rays (AP, axillary, and supraspinatus outlet views of the shoulder)



  • Supraspinatus view used to assess acromial morphology



  • MRI if indicated by exam



  • MR with intraarticular gadolinium can be helpful in diagnosing undersurface partial rotator cuff tear and the presence of internal impingement (MR sequencing in the ABER position)



  • Ultrasound can be used to help identify pathology in the rotator cuff, biceps, and subacromial space



  • CT arthrogram can be used to assess for rotator cuff pathology in patients that cannot have an MRI



Differential Diagnosis





  • Cervical radiculopathy




    • The patient’s history may include a history of neck pain or decreased neck range of motion. The exam may show neural tension signs, weakness in a nerve root distribution, distal motor weakness, dermatomal sensory deficits, and possible diminished deep tendon reflexes.




  • Biceps pathology (tenosynovitis, partial and complete tearing, and subluxation)




    • The physical exam may reveal tenderness over the biceps groove, positive Speed’s test, and pain with resisted supination. Patients may complain of pain radiating from the shoulder and into the anterior brachium.




  • Acute brachial neuritis (Parsonage Turner Syndrome)




    • Acute onset of intense, nontraumatic shoulder pain, which, occasionally, follows a viral illness. The intense pain is followed by weakness in the upper extremity. It can affect multiple areas of the brachial plexus, but can be isolated to a single nerve (suprascapular nerve).



    • MRI of the shoulder may show edema in the supraspinatus and infraspinatus if they are deinnervated.




  • Suprascapular neuropathy




    • Can be caused by compression of the nerve at the suprascapular notch. This results in weakness of the supraspinatus and infraspinatus muscles.



    • Spinoglenoid ganglion cyst causing compression of the suprascapular nerve and weakness of infraspinatus only.



    • The physical exam will find increased weakness of external rotation only if the suprascapular nerve is affected at the spinoglenoid notch.




  • Calcific tendinitis




    • The patient’s history will indicate an acute onset of pain often associated with actual redness of the shoulder and the presence of calcium in the rotator cuff on X-ray.




  • Adhesive capsulitis




    • Patients present with shoulder pain with overhead activities. As the overhead motion causes intense pain, providers often do not test range of motion for symmetry. Loss of motion in all planes (but especially external rotation at the side and internal rotation) is diagnostic.




  • Contusions




    • The patient’s history will indicate a specific injury.




Treatment


Nonoperative Management





  • Activity modifications/rest



  • Physical therapy



  • Nonsteroidal antiinflammatory medicines (oral and topical)



  • Subacromial injection



Guidelines for Choosing among Nonoperative Treatments





  • Activity modifications/rest




    • Most patients have already begun to modify their activities based upon pain and symptoms. However, if their occupation or hobbies require overhead repetitive movements work restrictions or a discussion on specific modifications may be helpful. In most circumstances this will be combined with additional treatment.




  • Physical therapy




    • Helpful in restoring full and symmetric motion, preventing muscle atrophy, and improving pain. In the event of a rotator cuff tear, therapy can still be helpful in achieving full range of motion prior to any surgical intervention to avoid postoperative complication of adhesive capsulitis.




  • Nonsteroidal antiinflammatory medicines



  • Patients with evidence of stage I or stage II impingement are offered an antiinflammatory medicine.



  • Subacromial injection




    • Diagnostic injection with anesthetic can help to assess strength in an acutely inflamed shoulder that is examining with weakness. An injection with corticosteroid and anesthetic can be diagnostic as well as therapeutic. An injection is not indicated in the presence of a rotator cuff tear and should not be used indiscriminately. Due to damaging effects of atrophy and decreased quality of tissue, no more than three injections are recommended and they should be spaced at least three months apart.




Surgical Indications





  • There are no absolute indications for surgical intervention in rotator cuff pathology. Relative indications are as follows:




    • Failure of conservative treatment



    • Symptomatic full thickness rotator cuff tear



    • Symptomatic partial thickness rotator cuff tears that are greater than 50% of the thickness of the tendon



    • Persistent symptoms in patients with internal impingement that fail to improve with 3 months of therapy.



    • Persistent symptoms in patients with secondary impingement that fail to improve with 3 to 6 months of therapy




Aspects of History, Demographics, or Exam Findings that Affect Choice of Treatment





  • Length of symptoms and amount of dysfunction



  • Age of patient



  • Comorbidities affecting anesthesia clearance



  • The patient’s desire to return to sports/hobbies or a physically demanding profession



  • In the presence of a rotator cuff tear the amount of atrophy or fatty infiltration of the muscle belly, tendon retraction and elevation of the humeral head



Aspects of Clinical Decision Making When Surgery Is Indicated





  • Coracoacromial arch morphology



  • Symptomatic acromioclavicular arthrosis



  • Concomitant pathology including involvement of biceps tendon and/or labrum



  • Arthroscopic versus open rotator cuff repair and distal clavicle resection



  • Benefit of tendon transfers for irreparable tendon tears



  • Risks and benefits of concomitant versus staged surgery when there is a component of adhesive capsulitis associated with rotator cuff tendon tear



  • Type of fixation for repair (anchor configuration, stitch configuration, anchor material, etc.)

    Guiding Principles of Nonoperative Rehabilitation





    • All aspects of rehabilitation for shoulder impingement are evaluation driven and include a logical progression of exercises to correct the biomechanical deficits identified in the evaluation.



    • Avoid positions and activities that compromise the subacromial space and stress injured structures of the shoulder.



    • A systematic evaluation must be performed to identify the specific cause and subtle underlying cause of shoulder impingement. One must be cognizant that multiple causes may be responsible for the shoulder pathology.




      • Determine type of impingement




        • Primary



        • Secondary



        • Internal




      • Special tests to determine the mobility of the glenohumeral joint are key aspects of evaluation of the patient with rotator cuff impingement.




        • Evaluate to identify glenohumeral hypermobility and subtle instability as well as glenohumeral hypomobility.



        • “Failure to identify patients with glenohumeral joint hypermobility and underlying instability properly can result in the inappropriate use of capsular stretching and mobilization techniques that could further jeopardize shoulder stability and decrease the potential success of the rehabilitation program.”




      • Resting scapular position and dyskinesis.




    • Exercises must be performed with proper technique, including good scapular control. If proper technique cannot be maintained, the exercise must be modified.



    • Based on the results of systematic review by Kuhn , it is recommended that patients receive supervised physical therapy for exercise and manual therapy 2 to 3 times per week initially. When manual therapy is no longer warranted and the patient demonstrates good technique with their home exercise program, frequency of physical therapy visits may be reduced to progress the patient’s home exercise program as needed.



    • Kuhn concludes that range of motion and flexibility exercises be performed daily and strengthening performed 3 times a week.



    • Proprioception and neuromuscular control exercises should be practiced multiple times daily.



    • Conservative treatment of shoulder impingement is thought to be unsuccessful if no improvement is seen with 12 weeks of an evaluation-driven rehabilitation program and coordinated medical care. By 6 to 9 months, maximum medical improvement is typically obtained.




    Phase I: Acute Phase (weeks 0 to 2)


    Goals





    • Alleviate pain and inflammation (nonsteroidal antiinflammatory agents)




      • Possible subacromial injection of local anesthetic and a corticosteroid



      • Use of modalities (cryotherapy, iontophoresis, phonophoresis, TENs unit, ultrasound, E-stim) to help alleviate pain




        • Note that research does not support the use of passive modalities including ultrasound, low-level laser therapy, and electromagnetic field therapy as effective treatments for impingement syndrome so these modalities should only be used to adjunct treatment and not the premise of treatment in this phase.




      • Activity modifications and rest, avoiding activities that exacerbate symptoms




        • Patient education on activity modification and avoidance is very important in this phase so healing is not delayed





    • Acquire full passive ROM



    • Retard muscle atrophy by beginning submaximal, pain-free isometrics for internal and external rotation



    • Address abnormal resting scapular positioning and scapular dyskinesis by neuromuscular control exercises to normalize scapular muscle firing patterns




      • Consider scapular taping to improve resting scapular positioning as evidenced by Selkowitz et al.

    Techniques for Progressive Increase in Range of Motion


    Manual Therapy Techniques





    • Techniques used are evaluation based.




      • Glenohumeral joint mobilizations are




        • Empty end feels—Use grades I and II mobilizations for pain control and relaxation



        • Firm capsular end feels—Use grades III and IV to address motion deficits




      • Thoracic spine mobilization/manipulation is often necessary and should be included in this phase in patients who demonstrate increased thoracic kyphosis. Thoracic kyphosis causes an anterior tilt of the scapula, which reduces the subacromial space.




        • Thoracic spine extension exercises/flexibility exercises should be encouraged as part of a home excercise program



        • Patient education on proper sitting posture to maintain thoracic spine extension





    Soft Tissue Techniques





    • Some research supports the use of deep friction massage to the rotator cuff tendon insertion and radial nerve stretching for pain management in patients with impingement syndromes.



    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Stretching and flexibility exercise prescription is evaluation based. Can include exercises for flexion, scaption, internal rotation and external rotation.



    • Manual PROM, stretching and exercise prescription of stretching/flexibility for glenohumeral internal and external rotation should be ONLY done when patient has loss of total shoulder joint motion (external rotation ROM plus internal rotation ROM) compared to contralateral side. Note: IR/ER measurements should be done in the scapular plane at 90° abduction avoiding scapular compensation. Place hand on coracoid to feel for compensation ( Figure 6-6 ).




      FIGURE 6-6


      Technique for measuring glenohumeral joint internal rotation with scapular stabilization at 90° abduction.



    • Stretching/flexibility exercises should be modified to limit pain or avoid subacromial impingement with endrange stretching.




      • Keep in mind that glenohumeral internal rotation deficiency (GIRD) or loss of internal rotation and increased external rotation caused by humeral retroversion in overhead athletes is normal and provided the patient does not lack total arc of motion, internal rotation should not be stretched.



      • Note end feel of ROM to determine if the patient truly has tightness. An empty end feel is limited by pain, and stretching and aggressive joint mobilizations are not necessarily appropriate. Address capsular end feel and treat firm capsular end feels with grades III and IV joint mobilizations or firm muscular end feels with stretching. Oftentimes patients with motion loss have tightness of both noncontractile tissue (i.e., capsule, fascia) and contractile tissue (i.e., musculo-tendon) unit and both joint mobilizations and stretching exercises are appropriate.



      • Gentle range of motion exercises to address motion deficits. Motion exercises should be only done in a manner that limits symptoms and may need to be done initially as passive or active-assisted motions.



      • Pure abduction usually leads to increased symptoms and is usually avoided in the early phases. Stretching should be done in the scapular plane to avoid impingement of the structures in the subacromial space. (This may require a towel roll under elbow to stretch internal and external rotation.)



      • Stretching, particularly the posterior capsule, is often necessary in patients presenting with glenohumeral joint hypomobility and should be made a part of the HEP in this phase. There is little evidence supporting frequency and duration of flexibility exercises, but common practice encourages 3 times 60-second stretches for each exercise, 2 to 3 times per day.




        • Stretches may include the posterior capsule sleeper’s stretch ( Figure 6-7 ), the cross body stretch ( Figure 6-8 ), the rope IR stretch ( Figure 6-9 ), the T-bar ER stretch and passive/active assisted flexion stretch ( Figure 6-10 )

          FIGURE 6-10


          Flexion AAROM and stretching exercise to improve flexion range of motion.





    Other Therapeutic Exercises





    • Address flexibility of lower extremities, trunk and contralateral arm and prescribe a program to be done 3 times a week.



    • Lower extremity strengthening and cardiovascular exercise should continue and be encouraged especially in athletes planning to return to sport. Typically, strengthening and cardiovascular exercise for an athlete should be done 3 times a week at a minimum.



    Activation of Primary Muscles Involved





    • Choices of strengthening exercises should be made on an evaluation-based approach.



    • Scapular dyskinesis




      • Defined as alterations in dynamic scapular motion patterns



      • Alterations of resting position may also exist and need to be addressed



      • Three axes of rotation of the scapula provide three individual motions:




        • Upward/downward rotation about a horizontal axis perpendicular to the plane of the scapula, near the center of the scapula



        • Internal/external rotation about a vertical axis through the plane of the scapula



        • Anterior/posterior tilt about a horizontal axis through the scapula




      • The most common scapular dyskinesis patterns involve a downward rotation, internal rotation, and anterior tilt of the scapula. Lack of proprioception and delayed or decreased activity of the serratus anterior and lower trapezius are thought to contribute to scapular dyskinesis.



      • Some degree of scapular dyskinesis is evident in the majority of injured shoulders.



      • The physical examination should determine whether an altered resting position and scapular dyskinesis exist.



      • Restoring normal scapular position and control is a vital portion of a successful rehabilitation program for the shoulder joint.




        • Identify if the scapular dyskinesis is a result of poor neuromuscular recruitment or decreased muscle strength.



        • Phase 1 of scapular muscle training involves restoring normal resting position and proprioception exercises with the arm at the side.



        • Phase 2 focuses on muscle control and normalizing muscle imbalances. Typically, the upper trapezius (UT) is overactive in comparison to the lower trapezius (LT), middle trapezius (MT) and serratus anterior (SA). Exercises that minimize the UT/LT, UT/MT and UT/SA ratios by selectively activating the less active muscle are ideal for this phase.



        • Phase 3 of scapular muscle training includes general scapular muscle strengthening.




      • Exercises appropriate for this phase of rotator cuff impingement:




        • Prone shoulder extension with external rotation. Focus on posterior tilting scapula and middle trap recruitment. Work endurance by encouraging 10-second static hold with each repetition and repeat 10 times; 1 to 2 times per day ( Figure 6-11 ).




          FIGURE 6-11


          Prone extension with external rotation for middle trapezius and lower trapezius neuromuscular reeducation, strengthening and restoration of trapezius muscle imbalances.



        • Side-lying external rotation with rolled towel under arm in a pain-free range of motion. Perform 3 sets of 10 to 15 repetitions. Perform 1 time per day. ( Figure 6-12 ).




          FIGURE 6-12


          Side-lying external rotation with dumbbell.



        • Scapular orientation exercises to focus on correcting faulty resting position should be performed several times per day to make it habit.





    Milestones for Progression to the Next Phase





    • Shoulder AAROM/PROM restored and symmetric to contralateral shoulder.



    • Shoulder active range of motion should be painless for internal and external rotation. End range flexion may still be painful caused by impingement and painful arc may still exist with abduction.



    • Manual muscle testing of the rotator cuff should not be painful and should be at least 3 or greater on a 5 point scale for manual muscle test before progressing patient.



    • Good scapular resting position which constitutes scapula is flush to the thorax without evidence of a scapular internal rotation (prominent medial border), anterior tilt (prominent inferior angle) or downward rotation (inferior angle closer to thoracic spine than superior angle).



    Phase II: Intermediate Strengthening (weeks 2 to 8)


    Goals





    • Patients can begin strengthening in a completely pain-free manner: shoulder external, internal rotators, and scapular stabilizers. Strengthening should generally begin with the arm at the side and emphasize the small stabilization muscles as opposed to deltoid, pectorals, lats, etc.



    • Patient must be able to demonstrate good scapular control with all strengthening exercises. When patient fails to maintain good scapular mechanics, it is a sign of fatigue or too rapid progression during this phase.



    • Goal in this phase is to achieve full pain-free AROM.



    Management of Pain and Swelling





    • Continue modalities as recommended in Phase I as needed



    Techniques for Progressive Increase in Range of Motion


    Manual Therapy Techniques





    • Manual therapy techniques should continue until patient has full, nonpainful ROM.



    • Aggressive endrange joint mobilizations for patients with hypomobility may be required



    Soft Tissue Techniques





    • Continue as in Phase I



    • To restore normal, pain-free AROM



    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Stretching/flexibility exercises should continue until patient has full, nonpainful ROM.



    • Continue exercises from Phase I as needed. Emphasis should be on self-capsular stretching and HEP during this phase.



    • Once patient achieves this pain-free ROM, stretching/flexibility exercises should continue for maintenance of ROM and should be encouraged as part of HEP.



    Other Therapeutic Exercises





    • Progressive scapular stabilizer exercises that address patients’ neuromuscular control deficits, weaknesses, or muscular imbalances.




      • Exercises focusing on lower trap facilitation and strengthening with low upper trap/lower trap ratio




        • Forward flexion in side-lying with dumbbell.



        • Prone horizontal abduction with external rotation. Add a dumbbell when appropriate.




      • Exercises focusing on middle trap strengthening with low upper trap/middle trap ratio




        • Prone extension with external rotation with dumbbells.




      • Wall pushup plus for serratus anterior ( Figure 6-13 )




        FIGURE 6-13


        Wall pushup for serratus anterior strengthening.




    • Progressive rotator cuff isotonics. Exercise prescription should be 3 sets of 15 to 20 reps to create a fatigue response as these muscles are designed to be fatigue resistant, and restoring muscular endurance is important for shoulder stabilization with repetitive overhead movements.




      • Progress side-lying external rotation with dumbbell and towel roll under elbow



      • Begin standing Thera-Band internal and external rotation ( Figures 6-14 and 6-15 )




        FIGURE 6-14


        Thera-Band internal rotation at 0° abduction with towel roll to increase the subacromial space.



        FIGURE 6-15


        Thera-Band external rotation 0° abduction with towel roll to increase subacromial space and optimize infraspinatus muscle activity.




    • Once patient can demonstrate good scapular control and minimal fatigue with 3 full sets of 20 of the progressive scapular stabilizer exercises and progressive rotator cuff isotonics, progress to the following exercises. The patient must be able to perform the following exercise with perfect scapular control. If the patient cannot demonstrate perfect control, the patient may need to begin with AROM with or without gravity.




      • Standing and/or prone full can scaption with dumbbell for supraspinatus



      • Prone external rotation at 90° abduction with dumbbell for infraspinatus




    • Final progression includes the start of multiple angle submaximal strengthening such as D2 flexion PNF with Thera-Band with good scapular control ( Figure 6-16 ).




      FIGURE 6-16


      Thera-Band diagonal 2 flexion PNF for combined glenohumeral joint flexion, external rotation, and horizontal abduction and scapular upward rotation.



    Activation of Primary Muscles Involved





    • Muscle activation/strengthening of lower trap, middle trap, and serratus anterior muscles to improve scapular mechanics/upward rotation with overhead activities.



    • Strengthening of the rotator cuff muscles are necessary to improve or normalize glenohumeral joint stability and arthrokinematics. Since impingement syndrome often leads to specific weakening of the supraspinatus and infraspinatus muscles caused by impingement on their tendons in the subacromial space, special attention should be given to these muscles.



    Sensorimotor Exercises





    • Begin with rhythmic stabilization—3 sets for 30 to 60 seconds



    • Progress to higher level closed kinetic chain (CKC) stabilization exercises—3 sets for 30 to 60 seconds




      • Stabilization exercises using small medicine ball against the wall with manual perturbations ( Figure 6-17 ).




        FIGURE 6-17


        Rhythmic stabilization with medicine ball against the wall at 90° abduction using the scapular plane. Perturbations applied until fatigue.




    Techniques to Increase Muscle Strength, Power, and Endurance





    • Begin rotator cuff endurance exercises. Exercises should be done for 3 reps of 30 to 60 seconds at a time or until fatigued.




      • Bodyblade—IR/ER at 0° abduction with progression to IR/ER at 90° abduction ( Figure 6-18 )




        FIGURE 6-18


        Bodyblade stabilization in the 90°/90° position using the scapular plane.



      • TB external rotation oscillation ( Figure 6-19 )




        FIGURE 6-19


        Stabilization exercise with perturbations applied while the patient maintains their upper extremity in the 90°/90° position using the scapular plane.




    Milestones for Progression to the Next Phase





    • Full, nonpainful AROM



    • Seventy percent strength compared to contralateral side. The most valid and reliable measurement would be to use a hand-held dynamometer for manual muscle tests of all shoulder muscles (including rotator cuff muscles, biceps, triceps, and deltoids), and then comparing the results to the contralateral side.



    • No pain or tenderness



    Phase III: Advanced Strengthening (weeks 6 to 24)


    Goals





    • Goals of this phase of rehabilitation are to regain full shoulder strength. The patient should be able to resume all daily activities with no pain, weakness, or fatigue issues after this phase. Most patients do not require formal physical therapy beyond this phase unless they plan to return to higher-level sport, activity, or vocation.



    Techniques for Progressive Increase in Range of Motion





    • Patient should have full AROM/PROM in all planes and independence with a stretching/flexibility program for maintenance at this point.



    Manual Therapy Techniques





    • Continue as in Phases I and II for maintenance of ROM as needed.



    Soft Tissue Techniques





    • Continue as in Phases I and II for maintenance of ROM as needed.



    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Continue as in Phases I and II for maintenance of ROM as needed.



    Other Therapeutic Exercises





    • Progress rotator cuff isotonics




      • Increase weight or resistance of side-lying ER, Thera-Band IR/ER at neutral but keep repetitions high (3 sets of 10 or more repetitions, 3 times a week) as the rotator cuff is an endurance group of muscles.



      • Progress to Thera-Band IR/ER at 90° abduction—3 sets of 10 or more repetitions. Do 3 times a week.



      • Prone horizontal abduction in 135° abduction with external rotation—10 times 10-second holds, once a day




    • Progress serratus anterior strengthening to quadruped or plank position—3 times 10 reps; 3 times a week



    • Progress scapular stabilizer strengthening exercises




      • High and low rows for upper trap, middle trap and lower trap strengthening—3 times 10 reps; 3 times a week



      • Military press for upper trap strengthening—3 times 10 reps; 3 times a week




    Activation of Primary Muscles Involved





    • Progression of exercises should be towards doing exercises at 90° abduction in scapular plane especially when preparing an athlete to return to overhead sports.



    Sensorimotor Exercises





    • Stabilization on wobbleboard in quadruped or plank position with manual perturbations—3 times 30-second holds; 3 times a week



    • Perturbations throughout range with many exercises (D2 flexion, ER/IR with Thera-Band, etc.)



    • Stabilization on stability ball—3 times 30-second holds; 3 times a week



    Techniques to Increase Muscle Strength, Power, and Endurance





    • Progress rotator cuff endurance exercises




      • Thera-Band external rotation stabilization exercise in 90°/90° position and manual perturbations by therapist—3 times 30- to 60-second holds with good scapular positioning.



      • Isokinetic internal and external rotation strengthening if available




    Plyometrics





    • Initiate upper extremity plyometrics late in this phase of rehab only if patient plans to return to overhead athletics/vocation.




      • Trampoline toss and catch with light medicine ball—shoulder in 90°/90° position ( Figure 6-20 )




        FIGURE 6-20


        Medicine ball toss using rebounder for upper extremity plyometric training.



      • Supine catch and toss with medicine ball with shoulder in 90°/90° position



      • Eccentric internal and external rotation TB exercises with medicine ball or Thera-Band focusing on both cocking and follow-through phases of throwing/overhead sports




    Milestones for Progression to Advanced Sport-Specific Training and Conditioning





    • Full, nonpainful AROM



    • Full shoulder strength and endurance



    • No pain or tenderness



    • Satisfactory clinical examination



    • Able to resume all daily activities with no problems



    Phase IV: Return to Sport/Vocation (weeks 24 and beyond)





    • This phase of rehabilitation is only necessary for patients hoping to return to sport or high level manual labor vocations.



    • Rehab focuses on sport-specific training and improving full body cardiovascular endurance, power, and strength.



    • This phase may include a work hardening/work conditioning program and functional capacity evaluation or a progressive throwing, golf, or tennis program, etc. (see following sections).



    Specific Criteria for Return to Sports Participation: Tests and Measurements





    • At this point, the athlete should have full shoulder strength and endurance compared to contralateral side as evidenced by hand-held dynamometry measurements.



    • Depending on their sport, athletes should pass specific upper extremity functional tests before returning. Examples include:




      • Closed kinetic chain upper extremity stability test (applies to any sport using upper extremities)



      • Seated shot put test (applies to any sport using upper extremities)



      • Functional throwing performance index (for baseball players)



      • Underkoeffler overhand softball throw (for softball players)




    • Completion of interval program for the patient’s specific sport. Brotzman and Wilk’s Clinical Orthopaedic Rehabilitation, ed 2, 2009, (pages 189–195) provides several interval programs including a program for pitchers, a program for catchers, infielders, and outfielders, a program for tennis players, and a program for golfers.



    • Returning to sport is dependent on the specific sport and the level of competition.

    Postoperative Rehabilitation after Subacromial Decompression



    Stephen C. Weber, MD
    Donald Torrey, PT

    Indications for Surgical Treatment





    • Failure of nonoperative treatment over 3 to 6 months



    • Persistent activity-related pain that limits function



    • Previous attempts at nonoperative care, including nonsteroidals, activity modification, and a consistent rehabilitation program



    • Although prospective studies have found it difficult to establish the long-term benefits of steroid injections, the authors’ experience would indicate minimal risk and general benefit to their use in both diagnosis and treatment



    • Normal passive range of motion



    • Imaging studies negative for other findings, and consistent with the diagnosis of impingement, such as appropriate acromial morphology on radiographs ( Figure 6-21 ), and imaging findings on MRI consistent with impingement




      FIGURE 6-21


      Scapular lateral film, showing acromial prominence.



    • Temporary pain relief with the instillation of local anesthetic into the subacromial space



    Brief Summary of Surgical Treatment


    Major Surgical Steps





    • General anesthesia or scalene block at the preference of the surgeon



    • Lateral decubitus or beach chair position



    • Diagnostic arthroscopy to establish pathology, and to rule out other causes of shoulder pain



    • Treat associated intraarticular lesions as indicated



    • Arthroscope is then shifted to the subacromial space, and other subacromial pathology excluded ( Figure 6-22 )




      FIGURE 6-22


      Preoperative view of undersurface of acromion, suggesting impingement.



    • Transection or anterior release of the coracoacromial ligament



    • Inflamed bursal tissue (usually anterior half) is removed with a shaver or radiofrequency wand



    • Viewing posteriorly, initially remove 4 to 8 mm of the undersurface of the anterolateral acromion, depending on preoperative radiographs



    • Anterior acromion removed to this level and flush with remaining acromion



    • Avoid acromioclavicular (AC) joint unless this joint is symptomatic. However, a coplaning can be done to remove an inferior osteophyte at the AC joint that may also be causing “impingement” of the rotator cuff



    • Scope switched to anterolateral portal, and using “cutting block” technique the acromioplasty completed ( Figure 6-23 ); ensure that enough bone remains so that the risk of fracture (and stress fracture) is minimized




      FIGURE 6-23


      Completed acromioplasty, viewed from posterior.



    • Sling for comfort postoperatively



    Factors That May Affect Rehabilitation


    Anesthetic





    • Regional anesthesia can create issues with rebound pain and other unique complications to this anesthetic



    Surgical





    • Ancillary procedures performed, such as labral or rotator cuff repair, may impose restrictions on early mobilization.



    • If case is performed open, additional restrictions may apply to protect from injury to the attachment of the deltoid.



    Guiding Principles of Postoperative Rehabilitation





    • Understand whether the procedure involves simple acromioplasty, or repair of other structures that require additional rehabilitation restrictions



    • Although early motion is permitted, forced passive motion or early strengthening inhibit the healing process and can actually cause stiffness and protracted recovery



    • One needs to respect rate of ROM progression within these guidelines




    After Surgery—Postoperative Rehabilitation: Overview of Goals, Important Milestones, and Guidelines


    See Table 6-1 .



    Table 6-1

    Postoperative Rehabilitation Guidelines


































    Postoperative Time Immobilization ROM, rehab Restrictions
    0–14 days Sling as needed Pendulum exercises ADLS
    2–4 weeks None Passive and active assisted ROM ADLS, LE exercises only, stationary bike for aerobic exercise
    4–8 weeks None Thera-Band exercises Add running
    8–12 weeks None Assisted stretching if not full ROM Avoid overhead weight work sport-specific exercise
    >12 weeks None Resume full ROM Sport-specific exercise until return to sport unrestricted


    Phase I: Immediate Postoperative Period (days 0 to 14)




    Clinical Pearls





    • Patients need to be carefully monitored for stiffness regularly (no more than 3-week intervals). Early gentle ROM to minimize long-term problems is helpful. Early recognition of the development of postoperative stiffness can minimize this complication.



    • Passive stretching is to be avoided early to prevent increased pain and inflammation that can lead to later stiffness and prolonged recovery.




    Timeline 6-2

    Postoperative Rehabilitation After Subacromial Decompression
















    PHASE I (days 0 to 14) PHASE II (weeks 2 to 4) PHASE III (weeks 4 to 8) PHASE IV (weeks 8 to 12) PHASE V (weeks 12+)



    • Sling as needed



    • Ice



    • Codman’s pendulum exercises



    • Stationary bike




    • Sling discontinued



    • Pulley and wand exercises



    • Modalities if needed




    • Continue pulley and wand exercises



    • Start Thera-Band exercises



    • Hold other upper extremity exercises




    • Continue pulley and wand exercises



    • Continue Thera-Band exercises; initiate low resistance, high repetition exercise program below shoulder level



    • If full PROM not present, initiate gentle passive stretching exercises



    • Attention to scapular mechanics




    • Continue Thera-band



    • Start sport-specific exercise programs, Jobe exercises



    • Monitor return to sports carefully



    Goals





    • Minimize the effects of immobilization



    • Decrease pain and inflammation



    • Check for signs of complications (infection, neurologic injury, poor pain management). Review of postoperative scapular lateral radiograph can identify any early complications or inadequate bone resection. If these issues are not a problem, the next phase can be initiated.



    Protection





    • Sling as needed for comfort



    • No other protection needed for isolated acromioplasty



    Management of Pain and Swelling





    • Pain pumps are generally contraindicated



    • Oral pain medications or tylenol



    • As nonsteroidals can inhibit healing and decrease platelet function, these should be avoided for 5 to 7 days



    • Ice every 20 minutes an hour is reasonable



    • Cryotherapy units can burn skin and are outside FDA black box warning for 24 hours postoperatively if any local anesthetics are used



    • Patient Education: Using pillows or bolsters to find a position of comfort; sleep is often aided by a more vertical positioning



    Techniques for Progressive Increase in Range of Motion


    Manual Therapy Techniques





    • Codman’s Pendulum exercises are generally adequate



    • Exercises for hand, wrist and elbow can be initiated



    Other Therapeutic Exercises





    • Stationary biking can begin immediately after surgery

    Goals





    • Maintain program of treatment of pain and inflammation



    • Minimize effects of early loss of motion



    • Decreasing pain and improving ROM



    Protection





    • Sling can be discontinued



    Management of Pain and Swelling





    • Oral narcotics can be tapered or discontinued



    • Continue nonsteroidals or Tylenol



    • Although modalities can be useful, they are not a substitute for a supervised home therapy program



    Techniques for Progressive Increase in Range of Motion


    Manual Therapy Techniques





    • Patients are instructed in active-assisted ROM exercises with a pulley and stick ( Figure 6-24 )




      FIGURE 6-24

    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Pulley and wand exercises continue, with table slides, and wall walking exercises. All ROM exercises are done for 3 minutes 3 times per day. ROM work usually lasts for 1 to 2 months.



    Techniques to Increase Muscle Strength, Power, and Endurance





    • Thera-Band exercises begin in flexion, internal, external rotation and extension. Exercises are done 45 to 60 reps per day in sets of 15 ( Figure 6-25 and 6-26 ).




      FIGURE 6-25


      Band exercises for external rotational exercises.



      FIGURE 6-26


      Band exercises for internal rotation strengthening.



    • Keep all exercises below 90° plane.



    • Attention to scapular stabilization by doing exercises in mirror if necessary.



    • Scapular stabilization exercises



    • Band exercises only for first 6 weeks minimum; lasts 2 to 3 months



    Phase IV (weeks 8 to 12)




    Clinical Pearls





    • If full passive ROM has not been achieved, passive stretching can be initiated at this time. Heat and modalities can be helpful, but are not required. Focus at this point on passive stretching can avoid later complications with stiffness requiring later manipulation or arthroscopic release.



    • Studies have demonstrated that athletes who maintain appropriate scapulothoracic mechanics have significantly less injury. Avoiding loss of motion, especially internal rotation, can prevent development of glenohumeral internal rotation deficit (GIRD) and subsequent impingement.




    Goals





    • Normal scapulohumeral rhythm



    • Full PROM in all planes



    • AROM near full with minimal pain



    • Strength MMT 4/5 in all planes



    Management of Pain and Swelling





    • Oral NSAIDs, Tylenol



    • If pain continues to be a limiting factor, the patient should be returned to the surgeon for reassessment



    • Soft tissue techniques can be useful, but vigorous release techniques are generally counterproductive



    • Scar mobilization reasonable



    Other Therapeutic Exercises





    • Sport-specific exercises can be initiated for upper extremity work such as Jobe exercises using a gradual approach limiting resistance and increasing repetitions



    • High intensity above shoulder resistance work should be avoided until 12 weeks



    Phase V (weeks 12+)


    Management of Pain and Swelling





    • Ice application postexercise



    Techniques for Progressive Increase in Range of Motion





    • Patients should have achieved full AROM by this time



    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Passive stretching to continue if indicated



    Techniques to Increase Muscle Strength, Power, and Endurance





    • Although impingement is not generally a diagnosis of young throwing athletes, throwing athletes may begin light tossing at shorter distances and are instructed to avoid full windup throws until 20 weeks postoperatively. Interval training programs can be useful. Limited overhead stroke work for swimmers, tennis, and volleyball players.



    • Progression of throwing intensity may begin at 14 to 16 weeks as long as the patient demonstrates good mechanics. Throwing should be closely monitored and discontinued if the athlete exhibits any compensatory movement patterns or shoulder girdle discomfort. Resumption of other overhead sports can be managed similarly.



    • Progression to formal strength and conditioning commences once athletes have 4+/5 rotator cuff strength, full AROM, and are pain-free with activity.



    Criteria for Return to Sport


    General





    • Normal scapulothoracic and glenohumeral mechanics



    • Full AROM



    • Normal strength to manual muscle testing



    • Athletes at risk can benefit from isokinetic testing, emphasizing a 90% or better side-to-side difference in internal and external rotation.



    Sport-Specific





    • Coaches and trainers can be helpful in assessing specific sport rehab issues



    • Although no hard and fast rules apply, most patients without appropriate supervision return too soon, and reinjure or inflame previously injured or operated structures



    After Return to Sport


    Continuing Fitness or Rehabilitation Exercises





    • Total upper extremity and total body strengthening exercises



    Exercises and Other Techniques for Prevention of Recurrent Injury





    • Prevention of injury is best accomplished by maintaining the shoulder rehabilitation program throughout athletic participation, with specific emphasis on rotator cuff strengthening.

    Beyond Basic Rehabilitation: Return to Pitching after Subacromial Decompression



    Michael G. Ciccotti, MD
    Scott P. Sheridan, PT, ATC, CSCS

    Introduction




    Aspects of Pitching That Require Special Attention in Rehabilitation





    • Pitching exposes an athlete to a variety of forces during the act of throwing. With repetitive throwing, rotator cuff and periscapular muscle weakness can develop after which posterior capsular and/or rotator cuff contracture or inflexibility ensues.




      • In throwing athletes with posterior capsular and rotator cuff contracture, a posterior superior humeral instability occurs when the arm is abducted and externally rotated in the throwing mechanism creating an extrinsic subacromial impingement and glenohumeral peel back mechanism.



      • Peel back force can lead to superior labral and posterior rotator cuff fraying or tearing.



      • The main presentation may be subacromial impingement, although several pathologies may present.




    • In throwers, primary impingement is most likely to be an incomplete diagnosis, with varying degrees of rotator cuff injury, labral fraying or tearing, posterior capsular or rotator cuff contracture, and even anterior capsular laxity present.



    • Failure to correct nonshoulder abnormalities, such as core, hip, and leg weakness or inflexibility, may be just as likely as a specific surgical technique to prevent a throwing athlete from returning to preinjury level of sport.





    • The overhead or throwing athlete is exposed to a tremendous variety of forces during the act of throwing. This complex baseball throwing motion has been thoroughly evaluated by multiple authors.



    • The precise shoulder muscle activity in each of the five phases of pitching ( Figure 6-27 ) has been defined by several electromyographic studies.




      FIGURE 6-27


      The phases of throwing.

      (Redrawn from Ciccotti MG, Jobe FW. Medial collateral ligament instability and ulnar neuritis in the athlete’s elbow. American Academy of Orthopedic Surgery Instructional Course Lectures 48:384, 1999, figure 1.)



    • Other authors have identified the importance of the scapula, core, hips, and legs in this activity Kibler has described this Kinetic Chain Theory wherein the force imparted on a ball begins at the ground, is amplified through the legs, hips and core, and transmitted to the upper extremity via the shoulder.



    • Most often there is a precise balance in the musculoskeletal system that allows these athletes to perform this throwing maneuver painlessly and effectively. Not infrequently, though, that balance may be lost and injury may occur.



    • This injury takes a wide spectrum of form that often involves the rotator cuff and presents with impingement-like symptoms.



    • The etiologic factors vary from primary rotator cuff tendon failure, altered scapular mechanics, posterior capsular and posterior rotator cuff contracture, anterior capsular strain or laxity, labral fraying and tearing, to even infrequently primary subacromial impingement.



    • Primary subacromial impingement is defined as a repetitive injury to the anterolateral aspect of the rotator cuff (especially the supraspinatus portion) caused by supraspinatus outlet narrowing.



    • Kibler has proposed that the subacromial space is a dynamic region whose borders are affected by numerous intrinsic and extrinsic factors.



    • Intrinsic factors occur within the subacromial space and include acromial bone spurs, coracoacromial ligament hypertrophy, bursitis, calcific enthesopathy, and os acromiale.



    • Extrinsic factors occur beyond the subacromial space and include superior humeral head translation or altered scapulothoracic rhythm. Superior humeral head translation may result from rotator cuff tear or tendonopathy or labral injury. Altered scapulothoracic rhythm may be a result of glenohumeral instability, perishoulder contracture or inflexibility, scapular dyskinesis, acromioclavicular arthrosis or instability, biceps tendonopathy, or neurologic injury.



    • Rotator cuff impingement in the throwing athlete may be the result of any number of these etiologic factors occurring concomitantly. The thrower may be exposed to a cascade of events that result in some combination of several or all of these pathologies. With repetitive throwing, rotator cuff and periscapular muscle weakness can develop. With this a posterior capsular and/or rotator cuff contracture or inflexibility ensues. In throwing athletes with these two events, a posterior superior humeral instability occurs when the arm is abducted and externally rotated in the throwing mechanism. This creates an extrinsic subacromial impingement and glenohumeral peel back mechanism. This peel back force can lead to superior labral and posterior superior rotator cuff fraying or tearing. Although several pathologies may be present in these athletes, the main presentation may be that of subacromial impingement.



    • Previous sections in this chapter have outlined nonsurgical rehabilitation of rotator cuff impingement syndrome. If this structured nonsurgical protocol does not allow the athlete to return to preinjury performance, then surgical treatment may be necessary.



    • Surgical treatment focuses on the specific pathologies present. For those overhead or throwing athletes with primary, intrinsic subacromial impingement, subacromial decompression has been proposed.



    • Initial reports on subacromial decompression in the overhead athletic population have noted inconsistent outcomes. These authors suggest this may be a reflection of the complex nature of this injury in the throwing athlete, which most often involves several of the previously described, inter-related pathologies. All of these factors require focused attention for a truly successful postoperative outcome.



    • In throwers, primary impingement is most likely to be an incomplete diagnosis, with varying degrees of rotator cuff injury, labral fraying or tearing, posterior capsular or rotator cuff contracture, and even anterior capsular laxity present. These shoulder-specific, concomitant pathologies may require focused surgical attention as well, including rotator cuff debridement or repair, labral debridement or repair, posterior capsular release, or infrequently even anterior capsular plication.



    • Furthermore, nonshoulder sources of disability such as core, hip, and leg weakness or inflexibility may be present in the throwing athlete. These nonshoulder abnormalities mandate focused attention in the postsurgical rehabilitation program after subacromial decompression. And, in fact, failure to correct these issues may be just as likely as the specific surgical technique to prevent a throwing athlete from returning to preinjury level of sport.



    Postsurgical Rehabilitation Program





    • The postsurgical rehabilitation after subacromial decompression depends on the specific surgical treatment performed.



    • For those throwers with primary, intrinsic subacromial impingement having undergone isolated subacromial decompression with, at most, debridement of the rotator cuff or labrum, the postsurgical rehabilitation follows principles similar to nonsurgical rehabilitation.



    • For those throwers undergoing concomitant rotator cuff or labral repair, special attention is focused on allowing biologic healing while preventing capsular contracture and muscular weakness. In addition, postsurgical rehabilitation after subacromial decompression in the throwing athlete necessitates attention to the extrinsic and nonshoulder factors described previously. Therefore, the rationale for the phased, progressive postsurgical rehabilitation after subacromial decompression in the throwing athlete is predicated on the specific contributing pathologies, the individual demands of throwing, and known biomechanical and kinesiologic principles.



    • The purpose of this chapter is to discuss the end stages of rehabilitation after subacromial decompression in the throwing athlete. The acute and intermediate phases of rehabilitation have been discussed in the previous chapter. (see Chapter 6 : Post Surgical Rehabilitation after Subacromial Decompression). However, it will be important to complete a thorough review of what has been accomplished in those phases and what should be evaluated to determine the readiness of an athlete to progress to the functional phase of rehabilitation after this surgical procedure.



    • The basic goals that should have been accomplished in the initial phases of rehabilitation are full, pain-free arc of motion, ability to complete basic rotator cuff and scapular stability exercises without symptoms, and total body conditioning that is expected for baseball.



    • Range of motion is particularly important in throwers. Of concern is placing the shoulder at risk by not properly identifying glenohumeral internal rotation deficit (GIRD) or changes in total rotational motion (TRM). GIRD, as defined by Burkhart et al. , is a greater than 20° loss of internal rotation on the throwing shoulder in comparison to the nonthrowing shoulder. Burkhart indicates the traction forces placed on the shoulder with throwing cause GIRD, and over time a thickening of the posterior inferior capsule occurs.



    • Wilk proposed the TRM concept, where the amount of external rotation (ER) and internal rotation (IR) at 90° of abduction are added and a TRM arc is determined.



    • Both concepts are appropriate ways to determine the shoulder at risk for injury, although pitchers with GIRD and TRM differences outside the 5° window are at the greatest risk of injury.



    • In addition to range of motion, the scapula plays a significant role in the rehabilitation of the throwing athlete. The scapula serves as a base for muscle attachment, positions the glenoid to encourage osseous stability of the glenohumeral joint, and acts as a link in proximal-to-distal sequencing for the function of the shoulder. The goal is to make sure that scapular asymmetry or scapular dyskinesis has been relatively eliminated.



    • Lastly, with the understanding of the kinetic chain as noted earlier in this chapter, the previous phases should evaluate several other aspects as they relate to return to throwing. These items are posture, spinal movement/mobility, lower extremity range of motion/flexibility, and conditioning of the athlete.



    • Once all the above factors have been completed, evaluated, and are satisfactory, the progression to the functional phase of rehabilitation can be initiated.



    • As indicated above, this chapter is dedicated to beyond basic rehabilitation and return to pitching after subacromial decompression. For the purpose of this chapter, a throwing program for a starting pitcher is discussed as opposed to a relief pitcher. The overall program in regards to exercise, conditioning, and techniques is similar, however, the total time dedicated to throwing and mound progressions for return to pitching would differ.



    • Periodization is the planned manipulation of training variables (load, set, and repetitions) to maximize training adaptations and prevent the onset of overtraining syndrome. Periodization of the exercises in this phase would be nonlinear or undulating.



    • In general, some modification of the exercise variables would be made on a weekly or biweekly basis. Exercises in this particular phase would be initiated at one set of 10 to 15 repetitions. The long-term goal would be to progress to 2 to 3 sets of exercises with repetitions of 25 to 30 per set.



    • Starting pitchers will need to prepare for a significant number of repetitions over the course of pitching in games, but also long tossing on a daily basis.



    • In the off-season, the program may be completed on a 3 to 4 times per week basis; as spring training and the season begins, however, the program in place will be accomplished 7 days per week.



    • In some cases the speed of exercises will be increased, however, with the realization that no particular exercise can mimic the significant velocity involved in actually throwing or pitching a baseball.



    • Shoulder internal rotation during a pitch is the fastest human movement recorded, and it occurs in excess of 7250° per second.



    • Most programs are performed with minimal rest periods and exercise order may be the most important factor to modify.



    • When a throwing program is just being initiated, the order may be less important (other than the necessity to accomplish a dynamic warmup before throwing).



    • As the number of throws, distance, and mound progressions are accomplished, limited strength work is completed before throwing.



    • Once the pitcher is back to games, the program should be reevaluated to accommodate the typical 5-day rotation that is set up for a starting pitcher.



    • Overall this phase of rehabilitation will be broken down into three programs: Advanced strength and conditioning, Performance enhancement techniques, and Sport-specific training. This is done to better define each area; however it should be understood that these programs are all occurring and overlapping during the functional phase of rehabilitation after subacromial decompression. These programs are initiated at approximately 8 to 10 weeks after isolated subacromial decompression and 16 weeks after decompression with either labral or rotator cuff repair. In addition and more importantly, during these programs it will be necessary to continually reevaluate each of the areas discussed above.



    Phase I : Advanced Strength and Conditioning Programs


    Program Design/Performance Training Program





    • Includes exercises and activities relative to spinal movements, core exercises, and the lower extremity, all of which are key in returning the throwing athlete after subacromial decompression.

    * The acute and intermediate phases of rehabilitation have been discussed in the previous section Postsurgical Rehabilitation after Subacromial Decompression.



    Sport-Specific Concepts of Integrated Training





    • The initial sport-specific concepts to be addressed in this program are to make sure lower extremity flexibility and spinal mobility are maintained or improved. The exercises and manual therapy skills to be initiated are determined through the evaluation process described above.



    • Specific techniques used to address the posterior chain restrictions include:




      • Hamstring progressions in a True Stretch device ( Figure 6-28 ).




        FIGURE 6-28


        Hamstring progressions in a True Stretch device during Phase I.



      • In addition to the athlete performing these motions in the True Stretch, the therapist can assist in providing additional stability or manual contacts to address specific limitations ( Figure 6-29 ).




        FIGURE 6-29


        Therapist providing additional stability and manual contact for athlete while in True Stretch device during Phase I.



      • Furthermore, as part of the regular shoulder stretch routine, a general spinal stretch can be included ( Figure 6-30 ).




        FIGURE 6-30


        General spinal stretch during Phase I.




    Training Principles Used in the Design of the Program





    • Typical limitations seen in the overhead athlete include, but are not limited to, posterior chain myofascia, hip internal and external rotation, and spinal motion in positions of side bending and rotation.



    • It is important to maximize functional range of motion for baseball. However with the progression of mobility that is created from these activities, it will be important to perform strengthening within the newly gained motions. As stated by Gary Gray, “do not create mobility without sufficient stability”.



    • With the mobility program in place, exercises to include multiplanar actions and core stability need to be initiated. There are several options for exercises in this area with many modifications that can be made, limited only by the imagination of the therapist. Some particular concepts that are beneficial are multiplanar lunges with progressions of upper body and spinal movements. Even within these simple exercises, there are endless options of progressions. It is important that the lunges are performed in each plane and that one progression is the addition of either bilateral overhead flexion ( Figure 6-31 ) or opposite lunge side rotations ( Figure 6-32 ). These types of exercises involve multiple, coordinated movements, and special attention should be paid to activation of the core/transverse abdominis muscles during their completion by the athlete.




      FIGURE 6-31


      Bilateral overhead flexion while lunging during Phase I.



      FIGURE 6-32


      Opposite lunge side rotation while lunging during Phase I.



    Phase II: Performance Enhancement Training Techniques


    Program Design/Performance Training Program





    • The performance enhancement training techniques program includes concepts that are specific to the upper body and essential in returning the throwing athlete after subacromial decompression.



    • Initially shoulder and scapular exercises are performed to address individual muscles and are performed in isolation.



    • The goal of this program is to perform those same exercises, but add other components to increase the functionality of the exercise. One particular way this is accomplished is by adding balance components, lower extremity movements, or changing the surface upon which the exercise is performed to advance the quality of the exercise.



    Training Principles Used in the Design of the Program





    • One exercise progression can be taken from basic tubing exercises that are performed for scapular muscles in which they are progressed from split stance, to single leg, and finally split stance narrow base on a balance pad ( Figures 6-33 to 6-35 ).




      FIGURE 6-33


      Bilateral middle trapezius exercise in split stance during Phase II.



      FIGURE 6-34


      Exercises on single leg for stance side during Phase II.



      FIGURE 6-35


      Exercises in split stance on pad during Phase II.



    • Understanding the importance of balance on the stance side leg for pitching and incorporating that activity into the shoulder program is an important progression.



    • Also, exercises with an Impulse Machine can both increase the velocity at which exercises are performed and also involve balance progressions ( Figures 6-36 and 6-37 ).




      FIGURE 6-36


      Lower trapezius exercise in split stance during Phase II.



      FIGURE 6-37


      Lower trapezius exercise on stance side during Phase II.



    • In addition to exercises performed by the athlete alone, manual resistive exercises become a significant part of the shoulder program. Manual resistive exercises are often termed PNF exercises, however, they frequently do not follow the exact principles defined by proprioceptive neuromuscular facilitation. For the purpose of this chapter, these exercises will be referred to as manual resistive exercises. These techniques can mimic DI and D2 PNF patterns ( Figures 6-38 and 6-39 ) or simple isolated internal and external shoulder rotation.




      FIGURE 6-38


      Manual resistive exercises in a D1 pattern during Phase II.



      FIGURE 6-39


      Manual resistive exercises in a D2 pattern during Phase II.



    • Other variables within these exercises are rhythmic stabilization, emphasis on eccentric loading, or isometric holds. The benefit of these types of exercises being performed on a regular basis is that the therapist can gain valuable knowledge on how the quality of movement and strength are progressing.



    • Furthermore, passive stretching routine is incorporated into the program at this time. This passive upper body and spinal mobility program should include scapular mobility in multiple positions, passive range of motion in multiple planes, joint mobilizations, contract-relax techniques, pectoralis stretching, and spinal mobility or joint mobilizations ( Figures 6-40 to 6-42 ).




      FIGURE 6-40


      Side-lying scapular mobility exercises during Phase II.



      FIGURE 6-41


      Posterior glide joint mobilization during Phase II.



      FIGURE 6-42


      Pectoralis minor stretch in supine position with bolster during Phase II.



    • Lastly, within this program, any soft tissue techniques can be used to assist in the rehabilitation process. Moving out from anatomical and osteopathic circles, the concept that fascia connects the whole body in an ‘endless web’ has steadily gained support.



    Phase III: Sport-Specific Training


    Program Design/Performance Training Program





    • The sport-specific training program includes the throwing program, functional activities, and baseball conditioning to allow for return to pitching after subacromial decompression. To return to pitching in a game, several baseball specific activities must be accomplished. The obvious activities are long toss and throwing off the mound. However, other activities to be included at this time are hitting, base running, and fielding practice for pitchers.



    • Of those, the ability of the pitcher to field his position is paramount and is accomplished with the baseball coaching staff. It consists of what is termed pitcher’s fielding practice (PFPs). These activities involve fielding bunts, covering first base, and making the appropriate decisions to back up bases when indicated.



    • In preparation for these activities, the conditioning program will include interval running and agilities.



    Sport-Specific Concepts of Integrated Training





    • Often pitching is considered to be an endurance activity that has inspired many to advise their athletes to complete long distance running. However, the activity of a starting pitcher is an interval activity. It is composed of an average of 15 to 17 pitches in an inning followed by a rest period of approximately 5 to 10 minutes.



    • Therefore, it appears to be more appropriate to progress toward interval training as the athlete approaches return to game situations.



    • Lastly within this program is the most functional activity of long toss and pitching. The progression from long tossing to pitching on the mound is the paramount exercise of the entire rehabilitation program.



    Training Principles Used in the Design of the Program





    • It is crucial that the athlete is reevaluated prior to initiating a throwing program to ensure that the athlete is ready for this phase. Once it has been determined that a throwing program can be initiated, the trainer or therapist will need to consider the number of throws, distance, intensity, and frequency of the program.



    • There are many well-documented throwing programs and there is no research indicating one program is better than another. Therefore, the following program is a guideline, identifying important considerations as the athlete progresses in the throwing program.



    Sports Performance Testing


    Recommendations for Throwing Progressions





    • Initially begin with throwing 3 times per week. Increase the frequency after the athlete is satisfied with the symptom response to throwing. Typically progress to 2 days on and 1 off and then to daily tossing with recovery days built in. A recovery day is not an off day, but a day where the athlete may throw less total throws or a shorter distance. In our experience, complete days off from throwing are not always beneficial. Most athletes report feeling that they “took a step back or felt more stiff” after true off days.



    • The initials days of throwing may include 20 to 30 throws. As the number of throws increases, splitting the total number of throws into two sets is important. The challenge for many players is how they respond to throwing after cooling off. The goal for us has been to complete a total of approximately 100 throws with at least 25 at the maximum distance for that day.



    • The initial distance at which a player will throw should be 30 to 45 feet. The big question is what distance they should progress to. This should be based on previous long-toss programs, age of the player, and quality of throwing. If a player has never long tossed beyond 120 feet, they will need to be monitored with any progress beyond that distance. Some pitching coaches believe that no long tossing should occur beyond 120 feet for pitchers. Our experience is that overall mechanics of throwing should not be altered to reach a certain distance. In addition, beyond the distance of 90 feet, a drop step should be incorporated with the throw. Lastly, quality of throwing would be defined as throwing the ball with a good release point and keeping the ball on a line (not a high arc) to achieve the distance to be thrown.



    • The next decision is when to progress the athlete to the mound. There is no exact formula for this decision. The athlete must demonstrate quality mechanics, arm strength with throwing, and a good response to throwing on consecutive days. Additionally, all the areas reevaluated before initiating the throwing program must be at a satisfactory level. The initial time on the mound may involve as few as 15 throws and may be thrown at less than the full distance (either in front of the rubber or with the catcher in front of the plate). Often we will have 2 or 3 days between these sessions and then progress over time to every other day or back-to-back days. Much of this will be determined based on the type of pitcher and the overall response to throwing off the mound. The number of pitches on the mound will progress from 15 to as many as 70 or 80 for a starting pitcher. In addition, progressions from one set of throws on the mound to multiple sets must be accomplished for starters. This will be referred to as “up and downs” by many pitching coaches. As mentioned earlier, the ability to return to throwing after cooling off (simulating between innings) is often a challenge in the rehabilitation process. Furthermore, with respect to pitch types, typically fastball and change ups are initiated first; and when the athlete is comfortable and confident with his velocity and control of those two pitch types, then breaking pitches are added.



    • Finally the athlete will progress back to game situations. This may initially be accomplished with throwing live batting practice to his teammates and then creating game simulated activities. The final decision to make is when to return the player to a game. This decision will be made based on performance in simulated games and when the quality of pitching is acceptable to the player, athletic trainer/physical therapist, and coaches. The initial game situations may involve limitations in innings, pitches, and even time of the game in which the athlete is used.



    • The goal is for the player to return to his previous level of competition after subacromial decompression. It will be important to continue to monitor and reevaluate the player throughout the entire rehabilitation process and beyond.



    • The player should be reminded of the need to continue with his rehabilitation program even after he has returned to pitching. The athlete must understand the need to address the entire kinetic chain as he continues to throw.



    • It is the responsibility of the medical staff to constantly reevaluate the athlete and ensure that he is consistent with the program.

  • A controlled laboratory study was performed on 17 healthy, collegiate baseball pitchers throwing fastballs from varying distances (18.4 meters from a mound, 37 meters, 55 meters, and maximum distance). Kinematics and kinetics were evaluated with a three-dimensional motion analysis system. It was noted that hard effort, horizontal, flat-ground throwing was biomechanically similar to pitching from a mound. Maximum distance throwing produced higher shoulder internal rotation and elbow varus torques as well as kinematic changes, and so should be used cautiously for rehabilitation and training.

    Mark Rogow, ATC, CSCS
    Charles E. Rainey, PT, DSc, DPT, OCS, SCS, CSCS, FAAOMPT



    Guiding Principles of Nonoperative Rehabilitation





    • Establish diagnosis: Identify if there is GIRD (Greater Internal Rotation Deficit), posterior capsular hypomobility, a lack of rotator cuff and/or scapular strength and endurance, acquired glenohumeral anterior instability, labral and/or rotator cuff injury, or a combination of a number of these dysfunctions/pathologies



    • Establish a plan to address each of these conditions



    • Optimize postural alignment



    • Address SICK (Scapular malposition, Inferior medial border prominence, Coracoid pain and malposition and dysKynesis of scapular motion) scapula and/or scapular dyskinesis

    • Monitor progress closely and advance forward in the program as milestones are achieved



    • Moving forward in a program is less determined by time than it is by goals attained; however, it is possible to be working in multiple phases given we are rehabilitating and improving the performance of the entire kinetic chain, rather than just a single body part



    • Return to ADLs (Activities of Daily Living) without pain



    • Increase strength, power, endurance, and myokinematics of entire kinetic chain



    • Return to sport




    Phase I: Movement-Mobility (weeks 2 to 4)

    • Patient has knowledge/understanding of shoulder function, mechanical awareness, injury predispositions, and recovery needs



    • Continue maintenance drills, exercises, movement patterns, correctives, stretching, and sport-specific training



    Protection





    • To optimize healing, for nonoperative care, minimize hyperangulation (no hyperabduction, no external rotation at 90/90 or ER above 90 abduction).



    • Do not sleep on the injured shoulder or with the arm in an overhead position.



    • Establish or maintain good posture and good scapulothoracic position throughout the day. Kinesiological taping may help reinforce and/or reeducate critical postural and suprascapular muscles.



    Management of Pain and Swelling





    • Electrotherapy (INF/TENS/high voltage galvanic) may be used if there is pain, inflammation, spasm, or muscle guarding



    • Oral NSAIDs and pain medications as prescribed by physician



    • Iontophoresis may be indicated



    • Cryotherapy as needed for pain and swelling



    • Compression/sports wrap if swelling



    Techniques for Progressive Increase in Range of Motion


    Physical therapy begins immediately after evaluation by a physician and rehabilitation specialist. This phase should include an evaluation, discussion, and plan. Active physical therapy care should begin as soon as possible.


    Manual Therapy Techniques





    • Manual therapy in Phase I is indicated if there is palpable muscle spasm, tightness, and point tenderness to anterior, posterior, superior, and inferior structures of the glenohumeral joint.



    • Manual therapy techniques to include contract/relax PNF and muscle energy. The authors have found better results with using contract-relax techniques during both self-stretching and therapist-assisted stretching versus passive stretching alone.



    • Begin gentle mobilization of posterior and inferior capsule if patient has tight posterior capsule and/or restrictive inferior glenohumeral ligament complex. Use manual therapy for the scapulothoracic joint, lumbar, thoracic, cervical spine, and pelvis if range of motion is limited and lacks necessary mobility.



    Soft Tissue Techniques





    • Soft tissue massage/mobilizations, IASTM (instrumental assisted soft tissue mobilization), and trigger point dry needling are all indicated to reduce spasm, tightness, reset muscle tendon units, and improve joint restrictions. Cross friction massage is indicated for biceps tendon and teres minor tenderness/tendonitis which are common secondary side effects of internal impingement.



    • Other soft tissue therapy techniques include using foam rolls, myofascial/lacrosse balls, and massage sticks. These are all also effective objective measurements of effectiveness and produce increased ROM and decreased pain level.



    • This does not need to be a “passive” treatment. Be sure to include active movement while using these tools. Moving the joint or contracting the muscle while applying the pressure of the modality will educate the patient as to where there are soft tissue restrictions, muscle spasm/tightness, as well as trigger points. This “active” approach is effective while working on the pec minor, rhomboids, and posterior cuff (taking the shoulder through flexion, IR/ER, and abduct), as well as deep soft tissue structures in the hip (taking it through IR/ER and flexion).



    • The common muscle tendon units/soft tissue that tend to be hypomobile lack pliability and/or are joints that lack mobility with internal impingement, such as pectoralis minor, levator scapulae, scalenes, upper trap, teres minor/infraspinatus, posterior capsule, scapula-thoracic joint, thoracic spine, and contralateral hip.



    • Be sure to evaluate horizontal adduction, internal rotation, and the sleeper stretch position ( Figure 6-43 ) bilaterally. While looking at horizontal adduction be sure the scapula is immobilized and in a neutral position (not retracted or protracted). The scapula needs to be fixed against the thorax before horizontally adducting the humerus.




      FIGURE 6-43


      Sleep stretch at 90°.



    • The intent of treatment during this phase is to address any and all soft tissue restrictions surrounding the shoulder and throughout the kinetic chain.



    • Muscles that when tight affect, or can contribute to, scapular dyskinesis:




      • Pectoralis minor



      • Levator scapulae



      • Upper trapezius



      • Infraspinatus/teres minor



      • Latissimus dorsi




    • Techniques include, but are not limited to, if indicated:




      • Inferior and posterior glides during horizontal adduction and internal rotation of the humerus on the glenoid (low grade end range mobilization glides; performed by therapist)



      • Side-lying horizontal adduction stretch (self-stretch)



      • Standing with scapula pinned against wall; horizontally adduct humerus (self-stretch)



      • Standing with scapula pinned against wall; internally rotate humerus with shoulder abducted at 70° and at 90° (self-stretch)



      • Supine horizontal adduction stretch (therapist assisted)



      • Sleeper stretch/modified sleeper stretch at 70°, 90° and 110° (self and therapist assisted)




    • If there is any anterior or subacromial pain while performing the sleeper stretch, modify the position by performing 1), 2) and/or 3), as the stretch should only be felt in the posterior and posteriolateral shoulder:



      • 1)

        Rotate torso away from elbow 10° to 20° then reattempt stretch.


      • 2)

        Increase the angle of the elbow from 90° out to 120° to 135°.


      • 3)

        Lower position of humerus from 90° abducted to 50° to 70°.



      • Corner stretch (self-stretch) ( Figure 6-44 )




        FIGURE 6-44


        Corner stretch.



      • Doorway pectoralis major/pectoralis minor stretch (self-stretch)



      • Pectoralis minor on foam roll stretch (self and assisted technique)



      • Side-lying, supine, and prone flexion stretch (therapist-assisted)



      • Side-lying on foam roll and actively flexing and extending shoulder ( Figure 6-45 )




        FIGURE 6-45


        Side-lying on foam roller.



      • Standing shoulder extension (self-stretch)



      • Supine shoulder extension (therapist assisted)



      • Backscratch/Apley’s stretch (self-stretch with Thera-Band or towel)



      • Subscapularis release (therapist assisted)



      • Standing latissimus/thoracolumbar fascia stretch



      • Supine angular (diagonal) with rotation stretches (therapist assisted)




    Clinical Pearls





    • The authors have found better results with using contract-relax techniques during both self-stretching and therapist-assisted stretching versus passive stretching alone.



    • The key is initiating the low intensity contraction at the “first barrier,” the first feeling of tissue tension, not taking it to its end range, then giving a contraction. After contracting the muscle or muscle group the patient is trying to stretch, take the stretch to the next barrier, and then repeat. This technique also keeps the patient engaged and on task by making them an active participant in the stretch.



    • It forces the patient to pay attention and be in tune with where their extremity is and the direction it is going in, what angles are the most effective, and tissue tension differences at different angles; in the long run it forces them to become less dependent upon the therapist.




    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Aerobic/cardiovascular conditioning to begin right away, however running should not begin until full pain-free range of motion in the shoulder is achieved



    • Improve postural awareness



    • Address SICK scapula and scapula dyskinesis if present




      • Initiate activity of the serratus anterior, rhomboids, and mid-lower trapezius



      • Low row



      • Active assistive shoulder flexion and in scaption with cane, pulley, UE Ranger, tubing, or cable



      • Sternal lift: While seated or standing, on exhalation, force sternum toward ceiling while performing scapular retraction and depression. Hold 5 seconds and return to normal resting position.



      • Shoulder dump: While standing in split stance (normal stride length distance), slowly perform a throwing motion (without a ball or other object) emphasizing depression and retraction of scapula when torso is upright, and performing elevation and protraction of scapula when torso is flexed and rotated over forward stride leg; then reverse the exercise slowly. (Arm can remain at side or can begin in abducted/externally rotated position depending on symptoms of patient.)




    • Functional core stabilization exercises




      • Pelvic tilts



      • Partial crunches



      • Bridging ( Figures 6-46 and 6-47 )/single leg bridge ( Figure 6-48 )/bridge marching

      • Dead bugs (alternate arms, alternate legs, alternate arms and legs)



      • Supermans



      • Physio ball wall squats




    • Evaluate for and treat deep neck flexor inhibition (may need tissue work on suboccipitals, cervical extensors, and scalenes)

      • Supine cervical flexion




    • Teach diaphragmatic/belly breathing



    • Dynamic lower extremity exercises




      • Body weight squats



      • Lunges (in the sagittal, frontal, and transverse planes)



      • Step-ups



      • Lateral step-ups



      • Step-downs



      • Trendelenburg exercise



      • Thera-Band walking (forward, backward, side-step)



      • Romanian deadlift (RDL) (body weight only) ( Figure 6-50 )




        FIGURE 6-50


        Deadlift. A, Start. B, Finish.



      • Single leg RDL



      • Good morning exercise (body weight only)



      • Single-leg excursions (in the sagittal, frontal, and transverse planes)



      • Calf exercises



      • Hiking/incline on treadmill




    • All exercises and stretches should be done pain free. If the patient experiences soreness and/or stiffness in the injured shoulder, these side effects from exercise should resolve within 24 to 48 hours.



    • If they do not, then the clinician needs to reevaluate the exercise, treatment, and recovery programs of the patient as well as the quality of the reinforcement, movement, and mechanics when working on posture and scapular control.



    • It is critical to achieve good scapular control by minimizing scapular dyskinesis during overhead ROM before increasing volume and intensity of strength training, or the underlying issue of scapular dyskinesis and poor scapular control will either slow the athlete’s return to play or will significantly increase the athlete’s predisposition to reinjury.



    Activation of Primary Muscles Involved





    • As part of the muscle reeducation process, the patient needs to learn to recruit proximal musculature (trunk/core/pelvis/hip) before recruiting distally (extremities). The purpose is to improve motor control.



    • Avoid hyper-horizontal abduction, ER at 90/90 and ER above 90 ABD, and avoid any reproduction of symptoms.



    • Using proprioceptive neuromuscular facilitation (PNF) for the scapula, manually cue the scapula to elevate/depress, upwardly rotate/downwardly rotate, retract/protract.



    Sensorimotor Exercises





    • These activities are advisable and critical as soon as an axial load or perturbations can be performed without pain.



    • Performing upper and lower extremity proprioception and balance exercises will activate, improve, and control muscle patterns which in turn will improve postural and neuromuscular control.



    • They include, but are not limited to, single-leg stance on contralateral leg and single-leg stance on ipsilateral leg (eyes open and progress to eyes closed).



    • If more challenge is needed, add upper extremity row and scapular retraction with tubing during SL stance.



    • Kneeling, half-kneeling or standing with hand of injured arm on physio ball on floor or against wall doing up-and-down, left-and-right movement patterns, circles, rhythmic stabilization, and perturbations.



    • Quadruped weight shifts, quadruped with hand of injured arm on ball or wobble board (all exercises must not elicit, reproduce pain, or compromise good scapular/postural position).



    • Upper extremity sensorimotor exercises also include lying supine and balancing an object such as a kettlebell or dumbbell in the hand of injured arm. Be sure to “pack the shoulder,” consciously contracting all periscapular musculature as if to squeeze tight one’s armpit. The latissimus must be tonic. Each repetition is to be done for 15 to 30 seconds in length.



    • Then move to side-lying with the arm extended toward the ceiling or sky and again “pack the shoulder.” (Discontinue if painful.) This can also be executed with the arm outstretched while kneeling, half-kneeling, or standing, depending upon the patient’s ability to maintain good core/trunk stability while performing the exercise ( Figures 6-51 and 6-52 ).




      FIGURE 6-51


      Packing the shoulder (supine).



      FIGURE 6-52


      Packing the shoulder (side-lying).



    Clinical Pearl


    The rehabilitation program should move along a continuum. Its difficulty should increase over time with respect to the sport or desired activity and evolve from bilateral to unilateral, supported to unsupported, using active and passive movement, with and without load.



    Open and Closed Kinetic Chain Exercises





    • Closed kinetic chain (CKC) activities should take precedent over open kinetic chain (OKC) activities early on in the program, caused by their functionability and avoidance of unwanted stresses. CKC exercises improve sensorimotor function, joint proprioception and centralization, and stability.



    • Perform multiplanar, frontal, sagittal, and transverse planes exercises and focus on the weakest, the most easily fatigued and poorest performing planes of motion.



    • In Phase I all humeral movements should be kept below 90° of shoulder flexion and below 90° abduction.




      • CKC exercises include, but are not limited to:




        • Weight shifts left and right, up and down, forward and back, as well as diagonal and circular patterns with elbows at 90° or with elbows extended against wall, table, or floor



        • Pushup plus (slow and controlled concentric and eccentric components) on forearms or with elbows extended



        • Scapular clocks with arm extended against fixed surface, controlling movement of scapula/glenohumeral joint clockwise and counterclockwise



        • Ball/physio ball oscillations with arm outstretched



        • Seated towel slides protracting and retracting scapula



        • Seated towel slides upwardly rotate and downwardly rotate scapula (putting contralateral hand behind neck and actively cocontracting the contralateral scapula usually yields better dynamic scapular results)



        • Thumbtacks: Imagine gripping a thumbtack on the wall with each hand, then upwardly and downwardly rotate humerus/scapula and getting a scapular pinch end range external rotation)



        • Pulley exercise: This is an active exercise, not a passive one. Be sure the patient is firing their humeral and scapular depressors during both flexion/extension, scaption and abduction/adduction movement patterns. If pain free above 90°, you can take shoulder through full available pain-free ROM.





    Clinical Pearl


    The act of gripping has been shown to activate reflex contraction of the rotator cuff muscles which will stimulate glenohumeral mechanoreceptors. This in turn increases joint compression and dynamic muscular cocontraction improving joint congruity, reducing shear forces, and stimulating joint proprioceptors while enhancing dynamic stabilization.



    Techniques to Increase Muscle Strength, Power, and Endurance





    • In Phase I, work begins on lower extremity muscle strength, power and endurance.



    Neuromuscular Dynamic





    • Kneeling and half-kneeling (with narrow base) modified lifts and chops with or without resistance depending upon ability to stabilize hips and trunk ( Figures 6-53 and 6-54 )




      FIGURE 6-53

    • Quadruped (on all fours): Alternate arms, alternate legs, alternate opposite arms and legs



    • Bridging/single-leg bridge/bridge marching



    • Dead bugs: Alternate arms, alternate legs, alternate opposite arms and legs



    Clinical Pearls





    • A key premise of the dynamic neuromuscular stability approach is that every joint position depends on stabilizing muscle function and coordination of both the local and distant muscles to ensure neutral or centered position of joints in the kinetic chain. The quality of this coordination is critical for joint function and influences not only local, but also regional and global anatomical and biomechanical parameters in the kinetic chain.”



    • The goals of neuromuscular rehabilitation according to Lephart et al. are:




      • To improve cognitive appreciation of the shoulder relative to position and motion



      • To enhance muscular stabilization of the joint in the absence of passive restraints



      • Restore synergistic muscular firing and coordinated movement patterns





    Plyometrics





    • Low-level lower extremity plyometrics can begin in the final 1 to 2 weeks of Phase I




      • Low-intensity dot drills, box drills, cone/footwork drills, jump rope, one- and two-legged hops, skipping, low-level bounding




    Functional Exercises





    • Ground-based exercises for the lower extremities (that do not load, compromise, or force the shoulder into flexion or abduction above 90°). Many are listed above, however the athlete should add additional exercises that incorporate movement patterns specific to the athlete’s sport.



    Sport-Specific Exercises





    • Review all sport-specific exercises related to the athlete’s sport. Consider each exercise, movement pattern, or sport-related activity that does not invoke stress on the injured shoulder. Examples of this might include taking groundballs without throwing, foot work, and body positioning drills that do not involve the affected shoulder.



    • Maintain indoor and outdoor cardiovascular/aerobic fitness.



    Milestones for Progression to the Next Phase





    • No pain at rest



    • Very little to no pain with increased activity



    • Good scapulothoracic mobility and control



    • Full glenohumeral motion



    • If present, eliminate GIRD if patient is not an overhead athlete



    • Core/trunk/pelvic stability, posture, and scapular kinesis need to have improved if the need was there



    • Improved hip motion and symmetry



    Note: Mobility/ROM are measured and assessed via goniometry measurement, so that right versus left extremities are within 10° of one another to achieve symmetry. Stability/postural control are measured via administrator’s observation, so that movement quality is high and no compensatory/unwanted motion are observed during these movement patterns.


    Phase II: Stability-Strengthening (weeks 4 to 8)


    Volume/duration: Perform 10 to 15 reps, 1 to 3 sets per exercise, depending on quality of movement and minimizing the presence of compensatory movement patterns. Exercise will be terminated when there is a decrease in movement quality and/or movement compensations noted.


    Goals





    • Continue to protect healing tissue; not ready to resume mechanics of the causation of injury



    • Shoulder stretching needs to continue, most importantly the horizontal adduction and sleeper position stretching



    • Begin to address rotator cuff strength deficits (iso­metrically, concentrically, and eccentrically) using low intensity, high-volume work, while simultaneously using correct scapular mechanics and good postural alignment



    • Increase strength training (volume and intensity) throughout this phase but be sure adequate recovery between sets and between workouts is accomplished



    • Maintain cervical, thoracic, lumbopelvic, and ankle mobility acquired in Phase I



    • Advance scapular, cervical, thoracic, lumbopelvic/hip/lower extremity stability training



    • Reinforce muscle memory of correct neuromuscular firing, going from conscious to unconscious control



    • Advance and challenge cardiovascular fitness



    Protection





    • Do not sleep on shoulder; do not sleep with arm/shoulder in overhead position (prone, supine or side-lying). “Crimping the garden hose” affects the rate of flow of the water down the hose much like sleeping on the shoulder and squeezing the neurovascular structures and vessels that feed the arm and shoulder. One bad night can negatively affect the patient for a day or more.



    Management of Pain and Swelling





    • Electrotherapy (TENS, IFC, Russian) may be used if there is pain, spasm, and muscle guarding



    • Oral NSAIDs and analgesics should be able to be discontinued in this phase



    • Cryotherapy as needed



    Techniques for Progressive Increase in Range of Motion


    Manual Therapy Techniques





    • Manual therapy techniques used in Phase I are also indicated in Phase II to not just maintain what has been accomplished, but to address any new issues that may arise or be uncovered.



    • Take advantage of this time to periodically evaluate the patient’s strength and range of motion, as well as the firing patterns of motor recruitment.



    Soft Tissue Techniques





    • The same soft tissue techniques listed in Phase I certainly can apply in Phase II to not only maintain what’s been achieved soft-tissue wise, but also to evaluate the tissue as new issues and changes in tissue tension, capsular, and muscular tightness emerge.



    Stretching and Flexibility Techniques for the Musculotendinous Unit





    • Although the patient has moved on to Phase II, it is critical that both the therapist and patient remain aware and on top of the patients kinetic chain mobility.



    • Many flexibility goals have been met up to this point, however the patient’s body type, posture, sport, and genetics are still programmed to return that athlete to the state of flexibility the athlete was in before the injury occurring. That being said, working on stretching and being “routine” with it needs to continue well beyond this program, much less beyond Phase I.



    • At this point identifying the few stretches to help maintain the patient’s flexibility would be beneficial because it is probably a bit of overkill to perform all of the stretches every day.



    • Commonly the horizontal adduction stretch and modified sleeper stretch need to be continued 3 to 5 times per week. More aggressive techniques (such as active assistive and active isolated stretching with the use of a band, tubing or towel) can be used.
