This study investigated the efficacy of manipulation of cognitive self-control expectancy in EMG biofeedback training. It was predicted that a treatment procedure, which includes a positive-cognitive stage that establishes and reinforces a positive self-control belief system and also includes a training stage in EMG biofeedback, will be more effective in achieving a reduction in EMG activity than a treatment procedure which includes a negative-cognitive stage and which also includes ambiguous features prior to training and a treatment approach solely concerned with training. The study consisted of four groups with 10 subjects in each. In one group, expectation for inner control ability was created prior to actual training in reducing EMG activity. In the second group, expectation for negative self-control ability was created prior to EMG training. The third group only underwent the actual training in EMG. The fourth group served as a control group. The results show that the positive-cognitive self-control group was significantly more effective in reducing muscle activity than the other groups.
本研究调查了在肌电图生物反馈训练中操控认知自我控制期望的效果。预计一种治疗程序，包括一个建立并强化积极自我控制信念系统的积极认知阶段以及一个肌电图生物反馈训练阶段，在实现肌电图活动减少方面将比另一种治疗程序更有效，后者包括一个消极认知阶段、训练前的模糊特征以及仅关注训练的治疗方法。该研究由四组组成，每组有10名受试者。在一组中，在实际进行减少肌电图活动的训练之前培养对内部控制能力的期望。在第二组中，在肌电图训练之前培养对消极自我控制能力的期望。第三组仅接受肌电图的实际训练。第四组作为对照组。结果表明，积极认知自我控制组在减少肌肉活动方面比其他组显著更有效。
