Electrical activity in the right elbow flexors has been shown to have a high relationship with a general resting muscular tension factor. It was our purpose to evaluate the efficacy of EMG biofeedback in reducing electrical activity in this muscle group. It was found that EMG voltages were significantly reduced (P less than 0.001) due both to biofeedback treatment and to time of day (construed as a practice and/or restbreak effect). Replication of the experiment without biofeedback and designed to minimize the "restbreak" effect induced by repetitive testing produced no change in the EMG voltages. It was concluded that EMG biofeedback training is effective with the elbow flexor group, and the possibility for training subjects in overall deep relaxation through feedback from this one muscle group is suggested. The importance of the practice effect/restbreak is emphasized.
研究表明，右肘屈肌的电活动与一般静息肌肉张力因素高度相关。我们的目的是评估肌电图生物反馈在降低该肌肉群电活动方面的效果。结果发现，由于生物反馈治疗和一天中的时间（可理解为练习和/或休息效应），肌电图电压显著降低（P小于0.001）。在不进行生物反馈的情况下重复该实验，并旨在尽量减少重复测试引起的“休息效应”，结果肌电图电压没有变化。得出的结论是，肌电图生物反馈训练对肘屈肌组有效，并提出了通过该单一肌肉群的反馈对受试者进行全面深度放松训练的可能性。强调了练习效应/休息的重要性。
