Objective/Introduction

Isokinetic is a reference method for evaluation of muscle strength. It enables a functional diagnosis specifying levels of disability and performance deficits in the subject knee osteoarthritis.

Objective

To determine the profile isokinetic knee osteoarthritis in the subject compared to a healthy population.

Material/Patients and methods

Prospective study, descriptive and analytical cohort of 6 months of 30 knee OA patients compared with 15 healthy subjects collected in physical medicine and functional rehabilitation of Ibn Rushd University Hospital, Casablanca, Morocco. The 2 groups received a clinical and paraclinical evaluation more isokinetic evaluation.

Results

The mean age was 42.53 ± 11.41 years with female predominance (80%). The isokinetic evaluation noted a significant difference in the maximum torque peak (PCM) of the quadriceps (Q) and IJ between the 2 groups evaluated, a significant difference of work and the power of the Q and IJ between the 2 groups. It was found, in addition, no significant difference of both the fatigue index of Q and that the ratio IJ IJ/Q between the 2 groups assessed.

Discussion/Conclusion

Knee osteoarthritis is associated with pain and limitation of functional capacity but also to muscle weakness that affects itself the course of the disease where the interest of muscle strengthening the quadriceps and hamstrings which allows to increase muscle strength, stability and joint mobility leading to better pain tolerance and therefore a better quality of life.
