We carried out a controlled study on the voluntary control of the frontalis muscle by biofeedback procedures employing 20 normal subjects. Subjects were randomly divided into two groups of 10: (1) the biofeedback group and (2) the control group. Each of the two groups received five training sessions of about 40 minutes' duration each on different days. The results obtained are as follows: (1) In the biofeedback group, mean EMG levels decreased progressively and markedly from 2. 16 muVp-p min the first session to 1.54 muVp-p min in the last session. On the contrary, the control group did not show constant decreases in EMG levels over sessions. (2) The changes in the heart rate did not correlate with the changes in EMG activity. (3) The changes in the respiratory rate correlated with the changes in EMG activity.
我们对20名正常受试者采用生物反馈程序进行额肌自主控制的对照研究。受试者被随机分为两组，每组10人：（1）生物反馈组和（2）对照组。两组在不同日期各接受五次约40分钟的训练。获得的结果如下：（1）在生物反馈组中，平均肌电图水平从第一阶段的2.16微伏峰峰值逐渐显著下降至最后阶段的1.54微伏峰峰值。相反，对照组在各阶段的肌电图水平并未持续下降。（2）心率变化与肌电图活动变化无相关性。（3）呼吸频率变化与肌电图活动变化相关。
