The following controlled, preliminary investigation was designed to determine whether electromyographic biofeedback, in conjunction with therapeutic exercise, could influence the reacquisition of functional lower extremity movements in chronic hemiplegic patients. Both the control (standardized therapeutic exercise regimen) and experimental (therapeutic exercise regimen combined with electromyographic biofeedback) groups improved in ankle active range of motion; only the experimental group significantly shortened its timed ambulation over a carpeted surface. One patient in the experimental group who was given 12 additional training sessions showed further gains in knee and ankle joint angle measurements during walking. The apparent potential for rehabilitation of chronic hemiplegic patients and the benefits afforded to physical therapists from a standardized therapeutic exercise protocol are discussed.
