EMG analysis of the late exteroceptive suppression period of the temporal muscle activity is discussed as comparative methodology in the assessment of patients suffering from chronic tension-type headache and from migraineurs. After electrical perioral trigeminal nerve stimulation during maximum voluntary jaw occlusion, early (ES1) and late (ES2) exteroceptive suppression periods can be registered above the temples using surface EMG recordings. In patients suffering from chronic tension-type headache the duration of the late suppression period is shortened (p less than 0.001) compared to migraineurs or controls. However, patients suffering from episodic tension-type headache display late suppression periods of temporal muscle activity of differing lengths.
作为评估慢性紧张型头痛患者和偏头痛患者的比较方法，本文讨论了颞肌活动晚期外感受性抑制期的肌电图分析。在最大自主闭口期间进行口周三叉神经电刺激后，使用表面肌电图记录可在颞部上方记录到早期（ES1）和晚期（ES2）外感受性抑制期。与偏头痛患者或对照组相比，慢性紧张型头痛患者的晚期抑制期持续时间缩短（p<0.001）。然而，发作性紧张型头痛患者的颞肌活动晚期抑制期长度各异。
