In modification of a method published by Schoenen et al., early (ES 1) and late (ES 2) exteroceptive suppression periods elicited by perioral electrical trigeminus-stimulation during teeth-clenching were recorded with surface electrodes over the temporalis muscles. 29 patients with chronic tension headache, 20 with migraine, 7 patients with combined tension headache and migraine and 19 controls were examined. Duration of the late suppression period for the mean of three single shocks was highly significantly reduced in chronic tension headache sufferers and patients with combined tension headache and migraine when compared with migraine cases or controls. These results are in agreement with those of Schoenen et al. EMG analysis of temporalis late exteroceptive suppression is a helpful diagnostic method in primary headache. The reduction of ES 2 in chronic tension headache sufferers might suggest a deficient activation or excessive inhibition of the motoric trigeminus nucleus by pontobulbar inhibitory neurons which receive a strong input from limbic and nociceptive structures.
在对舍嫩等人发表的一种方法进行改进时，在咬牙过程中通过口周电刺激三叉神经引发的早期（ES 1）和晚期（ES 2）外感受性抑制期，用颞肌表面电极进行记录。对29例慢性紧张性头痛患者、20例偏头痛患者、7例紧张性头痛合并偏头痛患者和19名对照者进行了检查。与偏头痛患者或对照者相比，慢性紧张性头痛患者以及紧张性头痛合并偏头痛患者单次电击三次的平均晚期抑制期持续时间显著缩短。这些结果与舍嫩等人的结果一致。颞肌晚期外感受性抑制的肌电图分析是原发性头痛的一种有用诊断方法。慢性紧张性头痛患者中ES 2的降低可能表明脑桥延髓抑制性神经元对运动性三叉神经核的激活不足或抑制过度，这些神经元从边缘系统和伤害性结构接收强烈输入。
