Electromyographic (EMG) biofeedback was used in a controlled situation to teach patients with myofascial pain-dysfunction syndrome to relax and masseter muscle. Those receiving biofeedback were able to reduce their mean masseter EMG levels significantly. Concurrently, there was a reduction of symptoms. Seventy-five percent of the successfully treated patients required no further therapy during one year of observation.
