43名患有反复紧张性头痛的大学生被随机分配到4种肌电生物反馈训练条件中的一种。虽然所有的学生都认为他们正在学习减少额肌电活动，但实际的反馈取决于一半学生的肌电活动减少，另一半学生的肌电活动增加。在这两组中，学生还观看了假视频显示，旨在说服他们，他们正在实现大（高成功）或小（中等成功）的EMG活动减少。结果表明，无论实际变化的EMG活动，Ss接收高成功的反馈有显着更大的改善头痛活动（53%）比Ss接收中等成功的反馈（26%）。绩效反馈也与控制点和自我效能措施的得分变化前和治疗后。生物反馈训练期间这2个认知变量的变化与治疗后头痛活动的减少相关，而训练期间表现出的EMG活动变化与结果无关。(54参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
43 college students suffering from recurrent tension headache were randomly assigned to 1 of 4 EMG biofeedback training conditions. Although all Ss were led to believe they were learning to decrease frontal EMG activity, actual feedback was contingent on decreased EMG activity for half of the Ss and increased EMG activity for the other half. Within these 2 groups, Ss also viewed bogus video displays designed to convince them they were achieving large (high success) or small (moderate success) reductions in EMG activity. Results show that regardless of actual changes in EMG activity, Ss receiving high-success feedback had substantially greater improvement in headache activity (53%) than Ss receiving moderate success feedback (26%). Performance feedback was also related to score changes in locus of control and self-efficacy measures administered pre-and posttreatment. Changes in these 2 cognitive variables during biofeedback training were correlated with reductions in headache activity following treatment, while changes in EMG activity exhibited during training were uncorrelated with outcome.(54 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
