Biofeedback, relaxation training, and music: homeostasis for coping with stress.

This study compared the efficacy of five relaxation training procedures, four of which employed EMG auditory feedback: biofeedback only (BF), autogenic training phrases (ATP), music (MU), autogenic training phrases and music (ATP & MU), and a control group, in developing self-regulation of a "cultivated low arousal state" as a countermeasure to tensed muscular reaction to stressful imagery. Twenty subjects established a pre- and posttraining frontalis region EMG biofeedback baseline measurement. Sixteen subjects were assigned at random to the 25-minute taped relaxation training procedure. After eight training sessions (4 weeks), MU and ATP & MU groups achieved highly significant differences when compared with the control group. The ATP & MU group attained the lowest postbaseline arousal level measured by the EMG. EMG as a physiological measure for transfer of training functioned well in detecting the psychophysiological affect of stressful imagery.
