[Evaluation of the clinical effectiveness of biofeedback EMG on muscular relaxation and painful symptomatology].

The therapeutic effectiveness of EMG biofeedback on muscular relaxation and pain symptomatology has been analysed in a group of 24 dysfunctional patients presenting consecutively at the Prosthesis Department of the Odontostomatological Clinic. A good level of muscular relaxation was achieved in 22 cases; pain symptomatology disappeared totally in 19 and reduced considerably in 3 of 24 patients examined. Therapy failed in 2 cases. The method thus presents unquestionable therapeutic value in dysfunctional patients, particularly in cases with symptomatology that is mainly due to muscular hyperactivity.
