The absolute and proportional EMG levels of the frontal, temporal, and corrugator muscles of 37 migraine patients and 37 matched controls were recorded during three experimental sessions: adaptation and real-life and experimental stress, both of long duration. Migraine patients did not show significantly different absolute EMG levels but had higher proportional EMG levels of the corrugator muscle than controls in each session. Migraine patients did not have different facial muscle responses to stress, and the two experimental groups reacted similarly to real-life and experimental stress. No relation was found between muscle activity and reported headache within 24 h after real-life stress. Increased EMG activity due to stress does not seem to be a significant cause of headache in common migraine as defined in this study, but rather a response to pain. Migraine patients with headache during stress showed lower muscle tension than patients without headache.
在三个实验阶段记录了37名偏头痛患者和37名匹配对照者的额肌、颞肌和皱眉肌的绝对肌电图水平和比例肌电图水平：适应阶段、现实生活压力阶段和实验性压力阶段，二者持续时间均较长。偏头痛患者的绝对肌电图水平无显著差异，但在每个阶段，其皱眉肌的比例肌电图水平均高于对照组。偏头痛患者对压力的面部肌肉反应并无差异，两个实验组对现实生活压力和实验性压力的反应相似。在现实生活压力后24小时内，未发现肌肉活动与报告的头痛之间存在关联。在本研究定义的普通偏头痛中，压力导致的肌电图活动增加似乎不是头痛的重要原因，而更像是对疼痛的一种反应。在压力期间出现头痛的偏头痛患者的肌肉张力低于无头痛的患者。
