[email protected]. ~N ABSTRACT OF THE THESIS OF Pam W. Vredevelt for the Master of Science in Psychology presented June 14, 1985. Title: A Comparison of the Effects of EMG Biofeedback and Relaxation Training on Chronic Back Pain Patients. APPROVED BY MEMBERS OF THE THESIS COMMITTEE: Adriane M. Gaffuri, ~ -- This experiment examined the effects of EMG biofeed- back and relaxation training as compared with biofeedback alone. The following.dependent variables were examined: manifest anxiety, perceived pain, perceived relaxation, EMG activity, and locus of control. Back pain patients were assigned to one of two treatment groups. Group 1 was treated 2 with both EMG biofeedback and relaxation training. Group 2 was treated with biofeedback alone. It appears that both biofeedback combined with progressive relaxation and bio feedback training alone are effective in lowering muscle activity and perceived pain, and in increasing perceived re laxation.
