Recent articles have suggested that muscle biofeedback and transcendental meditation may be useful in treating chronic anxiety. To assess this, we conducted a controlled study comparing muscle biofeedback, transcendental mediation, and relaxation therapy. The study consisted of a six-week baseline period, six weeks of treatment, a six-week posttreatment observation period, and later follow-up. ⋯ There were no differences between treatments with respect to treatment efficacy, onset of symptom amelioration, or maintenance of therapeutic gains. We found no evidence suggesting that the degree of muscle relaxation induced by any of the treatments is related to the therapeutic outcome. Relaxation therapies as a sole treatment appear to have a limited place in the treatment of chronic anxiety.
