Abstract
The effect of visual feedback on the relative weight distribution while standing was studied in two patients with balance problems. An ABAB single case experimental design was used. During the A phase, EMG biofeedback for the arm was given while the patient was sitting. During the B phase, visual feedback of the weight distribution was used as a means of improving balance reactions. The Rivermead assessment revealed no change in overall motor performance in either patient. There was, however, a marked improvement in balance and in some characteristics of the walking pattern during the experimental (B) phase. This effect was sustained over time.
