The authors compared treatment of chronic anxiety with biofeedback-mediated electromyographic (EMG) relaxation to treatment with group psychotherapy in a control group. Feedback patients were given two weeks of EMG relaxation training followed by two weeks of self-practice. Significant decreases were found in the feedback group in electromyogram levels, mood distrubance, trait anxiety, and (to a lesser extent) state anxiety; no such decreases occurred in the control group. The authors suggest that EMG feedback can be an important adjunct therapy for chronic anxiety.
作者将生物反馈介导的肌电图（EMG）放松疗法治疗慢性焦虑症与对照组的团体心理治疗进行了比较。接受反馈治疗的患者先接受了两周的肌电图放松训练，随后进行了两周的自我练习。反馈组的肌电图水平、情绪障碍、特质焦虑以及（程度较轻的）状态焦虑均显著降低；而对照组则未出现此类降低。作者认为，肌电图反馈可以成为慢性焦虑症的一种重要辅助疗法。
