The study examined the efficacy of functional electric stimulation (FES) and biofeedback (BFB) treatment of gait dysfunction in patients with hemiplegia after stroke. These two therapeutic modalities were tested alone and in combination in a prospective, controlled, randomized trial. The authors hypothesized that in concurrent use, these two modalities would complement one another. Thirty-six hemiplegic patients undergoing rehabilitation after stroke were accepted for study and randomized into four groups to receive either control, FES, BFB, or combined therapies. Each patient received 30 minutes of treatment three times per week for six weeks, in addition to their general rehabilitation program. Quantitative gait analysis was performed biweekly on each subject during the experimental therapy and for four weeks afterward. Thirty-two subjects completed the study. Combined therapy with BFB and FES resulted in improvements in both knee and ankle minimum flexion angles during swing phase that were statistically significant with p = 0.05 and p = 0.02, respectively. Velocity of gait, cycle time, and symmetry of stance phases also improved. The length of time elapsed since the stroke did not prove to be a significant factor.
