Cerebral Palsy (Adults)

Cerebral palsy is not progressive, but its consequences are. Adults with cerebral palsy commonly experience earlier joint wear, increasing pain, loss of walking distance and rising fatigue — often from decades of compensatory movement patterns rather than from any change in the brain injury itself.

This means the goal in adult rehabilitation is usually different from childhood: protecting the function that exists rather than acquiring new function.

Spasticity management to prevent contracture. Maintaining walking distance and efficiency. Joint protection and pain management. Strength and endurance, which decline faster in cerebral palsy than in the general population. Where walking has already been lost, transfers, seating and upper limb function become the priority.

Programmes are delivered as intensive blocks of two to four weeks, repeated. A single long admission produces less than the same hours spread across repeated blocks with a home programme in between.

The brain injury that causes cerebral palsy does not worsen. What changes is the musculoskeletal system growing and ageing around it — muscles shorten, joints deform, and the energy cost of moving rises.

This is why a quarter or more of adults with cerebral palsy who walk see their walking decline, often earlier than peers without disability, despite a stable neurological condition 3. It is also why maintenance is a legitimate goal rather than an admission of defeat.

The Gross Motor Function Classification System describes what a person does rather than what is wrong: from walking without limitation at level one to being transported in a wheelchair at level five. It predicts trajectory better than the type of cerebral palsy does.

It matters practically because goals should match the level. Training independent walking in someone at level five is neither realistic nor kind, while accepting a wheelchair for someone at level two gives up something achievable.

Pain is common in adults with cerebral palsy: in pooled individual data from 1,243 adults, 70% reported pain, most often in the legs 2. It is frequently attributed to the condition and left alone. Much of it is mechanical and treatable.

Hip surveillance in childhood prevents one painful cause, dislocation of the hip: in a Swedish population-based programme, dislocations fell from 8% of children to 0.5%, and every child whose hip did dislocate reported severe pain at least periodically 4. Where displacement has already occurred, management is about function and comfort rather than about the radiograph.

It builds strength, but trials have not yet shown that this changes walking. A meta-analysis of exercise trials in adults with cerebral palsy found improved leg muscle strength, but no faster walking over 10 metres and no greater distance in timed walking tests 5. Few of the trials measured quality of life 5.

How exercise affects what adults themselves rank as important — quality of life, pain, mood and fatigue — is still unknown, although the types of exercise studied appear safe 6. Practising walking itself has very low- to low-quality evidence of improving walking speed 7. A walking goal is therefore trained directly and measured, rather than assumed to follow from stronger muscles.
