Genu recurvatum: auditory biofeedback treatment for adult patients with stroke or head injuries.

The purpose of this study was to test the effectiveness of the auditory biofeedback electrogoniometer in controlling genu recurvatum. Thirteen subjects who met predetermined criteria received supervised training, the aim being to assist them in controlling knee hyperextension. All subjects demonstrated ability to decrease genu recurvatum and even eliminate it. Utilization of an auditory biofeedback electrogoniometer should assist rehabilitation personnel in the management of this condition.
