Biofeedback to improve lower limb function after stroke

Does it have added value on top of usual care?

Rehabilitation after stroke typically involves repetitive task practice, with verbal feedback from a physiotherapist about performance. Feedback to the patient can be supplemented with biofeedback, that is, instant objective information about any aspect of the task (eg, position, force, muscle activation) via any sense (eg, visual, auditory, tactile). Previous reviews of the effect of biofeedback in stroke have been favourable, but have included trials with low methodological quality and trials where the amount of therapy time in the biofeedback and control group were not matched. A new review included only high quality trials that compared equal amounts of therapy either with or without biofeedback. 

Biofeedback is currently used infrequently, even though many biofeedback machines are relatively inexpensive and easily available. This study therefore gives physiotherapists working with people after stroke the impetus to utilise biofeedback more widely in their clinical practice, with the anticipated benefit of greater improvements in the patients' ability to stand up from sitting, maintain a standing position, and to walk.
