The purpose of this study was to determine whether the frontal muscles of the forehead during the imagination of an individualized stress situation reflect general arousal. Physiological arousal and subjective feelings of tension were measured during a stress and a relaxing imaginative situation, utilizing a counterbalanced design. Frontalis EMG during stress imagination was raised and was paralleled by more reported tension, elevated skin conductance, and trends toward increments in heart rate and respiration rate. The raised frontalis EMG can be seen as a consequence of the greater effort spent in the stress imaginative situation than in the relaxing one. This experiment supports an important assumption of the clinical application of frontalis EMG biofeedback to stress-related disorders. Other assumptions still remain to be examined.
本研究的目的是确定在想象个性化应激情境时前额的额肌是否反映了一般的唤醒状态。采用平衡设计，在应激和放松的想象情境中测量生理唤醒和紧张的主观感受。应激想象期间额肌肌电图升高，同时报告的紧张感增强、皮肤电导率升高，心率和呼吸频率也有增加的趋势。额肌肌电图升高可被视为在应激想象情境中比在放松情境中付出了更多努力的结果。该实验支持了额肌肌电图生物反馈在与应激相关疾病的临床应用中的一个重要假设。其他假设仍有待检验。
