Effect of Quadriceps Activity for Degenerative Arthritis Applied EMG Biofeedback Training

Young-Eok Kim, Dongyoun Kim

Abstract

This study performed in order to investigate the effect of isometric resistance exercise for vastus medialis oblique muscle with EMG(electromyography) biofeedback training which are applied to the patello-femoral joint of patients with osteoarthritis on the improve of function. The subjects had no neuromuscular disorders, and they were elder patients with osteoarthritis, 20 women. And the experiment was performed in control group, taping with EMG biofeedback training group respectively, and the measurement was carried out before and after the treatment and 4 weeks after the treatment. Motor unit action potential analysis with surface electromyography showed a significant change in RMS(root mean square) amplitude and MDF(median frequency) in vastus medialis oblique muscle(p
