Introduction
In neurological physiotherapy the evidence base for treatment interventions is a developing one (Pomeroy & Tallis 2002). Moves have been made by a number of researchers to identify what constitutes neurological physiotherapy. Studies by Ballinger et al (1999), Davidson & Waters (2000), Lennon & Ashburn (2000) and Lennon (2003), have begun to address this issue mainly in the form of surveys and focus groups. These studies have sought to isolate the components of neurological physiotherapy treatment and what concept of treatment physiotherapist’s professed to use. Previous studies by Nilsson & Nordholm (1992), Carr et al (1994), and Sackley & Lincoln (1996) as cited in Davidson & Waters (2000), identified that the main approach used by physiotherapists in the United Kingdom, although eclectic in nature, was based on the Bobath concept. This was supported by Davidson & Waters (2000) who reported that the majority of physiotherapists questioned (88%), professed to use the Bobath approach, although the majority of these also used other approaches in the treatment of their clients. The second most popular approach was identified as the Motor Re-learning Programme (MRP), though this was practised by only 4% of the respondents.

28-year-old male, admitted to ICU with extensive head injury following an assault
Ventilated and sedated, though sedation is being reduced as ventilator weaning commences

Flexion at wrists, fingers and elbows with adduction and internal rotation at shoulder joints
CASE STUDY 5 Head injury, long-term rehabilitation
Subjective assessment

22-year-old female, suffered a head injury 4 years ago following an RTA in which she was a passenger
On starting work, complained of high levels of fatigue. This has now settled
Complains of right leg feeling weak, with a fear of her knee giving way if walking any distance
HPC
MRI scan showed damage to the temporal and parietal lobes on the left due to a blunt piercing trauma
Underwent extensive surgery and rehabilitation at the time of injury

Tracheostomy tube changed during chest infection, communicates effectively by staff lip reading
Objective assessment
You are asked to focus your attention on seating and positioning difficulties.
Passive movement
Passive movements performed to all upper limb joints
Shoulder extension difficult to assess due to positioning in bed
Nursing staff present report that this has become an increasing problem since chest infection and they are concerned about skin integrity. Patient reports hand position causing concern though wants to be able to sit out in wheelchair so that he can spend more time with his sons
