Functional rehabilitation

Functional rehabilitation works on the activities a person actually needs to do — getting out of a chair, climbing stairs, carrying shopping, getting in and out of a car, lifting at work — rather than on isolated muscle groups in the hope of transfer.

The reason is that transfer is limited. Strength gained on a leg press does not automatically become the ability to rise from a low chair, because that task requires timing, balance and confidence as well as force.

It starts with what the person cannot do and works backwards. The task is broken into components, each trained at a level currently achievable, then reassembled and progressed towards the real thing in the real environment.

Goals are set with the patient and stated concretely — climbing the fourteen stairs at home without a rail, walking to a specific shop — because a goal that can be tested is a goal that can be shown to have been met.

Anyone whose problem is loss of ability rather than loss of a measurement: after stroke and brain injury, after joint replacement, in older adults after illness or a fall, after prolonged hospital admission, and in return-to-work rehabilitation.

It is the phase that turns clinical gains into ordinary life, and it is the phase most often cut short when a programme runs out of time.

By task performance and by validated functional measures rather than by strength alone. Timed chair rise, walking speed, stair performance and functional independence scores are recorded at the start and repeated.

We report those numbers. A programme that improved muscle strength but not a single daily activity has not achieved what the patient came for.

Strength gained on a machine transfers to daily life less than people expect 1. The nervous system learns the specific movement it practises, which is why standing from a chair is trained by standing from a chair.

So the programme is built from what the person actually needs to do — stairs at home, lifting a grandchild, getting into their own car — rather than from a generic list.

Load, speed, range, stability and cognitive demand can each be increased independently. Adding all of them at once is how a programme becomes discouraging.

Progression is planned and recorded, so the same task is measurably harder in week four than in week one rather than simply repeated.

Strength training on its own improves strength more than everyday ability. A Cochrane review of 121 trials in older adults found a large effect of progressive resistance training on muscle strength, but only a small improvement in overall physical ability and a modest gain in walking speed, although rising from a chair improved more 1.

Practising the task itself has direct support after stroke. A Cochrane review of 33 trials with 1,853 participants found moderate-quality evidence that repetitive task training improves walking distance and functional walking, and low-quality evidence that it improves arm and leg function, with benefits lasting up to six months 2.
