Biofeedback treatment of genu-recurvatum using an electro goniometric device with an acoustic signal. One-year follow-up

Abstract

The aim was to evaluate the effect of a biofeedback electrogoniometer in the control of recurvation of the knee while walking in patients with neurological diseases. Eighteen patients were trained daily for 12.8 sessions on average with an electrogoniometer attached to the knee, which gave a signal at a threshold value of 180° in order to avoid hypertension of the knee. The improvement was statistically significant even after one year.
