Functional electrical stimulation (FES) may improve recovery after stroke. We studied its effects in 38 postcerebral infarct patients. Twenty were randomly assigned to receive FES producing ankle dorsiflexion on the affected side and physical therapy. The remaining 18 received physical therapy only. Subjects were evaluated prior to commencing therapy, at its completion after 4 weeks, and again 4 weeks later using functional and electrophysiological measures. Functional deficit in most patients improved (p < 0.01). Although no significant differences were observed when those treated with FES and those not treated were compared at 4 and 8 weeks, there was significant improvement in the rate of recovery using an ambulation score (p < 0.05), and there was a similar trend in the Barthel Index for FES-treated patients (p < 0.1). Our results indicate that FES may confer additional benefit in acute stroke rehabilitation. Further studies are needed to delineate how best to use it.
