60 subjects participated in a test of the effectiveness of frontalis EMG feedback as a generalized relaxation technique. The experiment was performed in two parts. In the first part, 30 subjects were randomly allocated to a group receiving frontalis EMG feedback (n = 10), a group receiving non-contingent feedback (n = 10) and a group instructed to relax themselves (n = 10). Each group received one baseline session and five training sessions. EMG measurements from the frontalis, trapezius and masseter muscles taken prior to and immediately after the final training session indicated that the frontalis feedback group was more effective in lowering frontalis and masseter EMG activity (though not trapezius activity) than the controls. The second part of the experiment was identical to the first with the exception that the subsidiary muscle sites were the forearm and leg extensors. The results showed that frontalis feedback was no more effective than controls in lowering the EMG levels of these muscles.
60名受试者参与了一项关于额肌肌电图反馈作为一种通用放松技术有效性的测试。实验分两部分进行。在第一部分中，30名受试者被随机分配到接受额肌肌电图反馈的组（n = 10）、接受非相关反馈的组（n = 10）和被指示自行放松的组（n = 10）。每组接受一次基线训练和五次训练。在最后一次训练前和训练后立即从额肌、斜方肌和咬肌进行的肌电图测量表明，与对照组相比，额肌反馈组在降低额肌和咬肌肌电图活动（但不是斜方肌活动）方面更有效。实验的第二部分与第一部分相同，不同之处在于辅助肌肉部位是前臂和腿部伸肌。结果表明，额肌反馈在降低这些肌肉的肌电图水平方面并不比对照组更有效。
