摘　　要：目的:探讨三叉神经颞肌、咬肌外感受抑制(ES)检测紧张型头痛(TTH)的应用价值。方法:对30名紧张型头痛患者及30名正常志愿者利用肌电图(EMG)刺激眶下神经进行ES试验,检测颞肌、咬肌ES的潜伏期和时限。结果:与正常对照相比,紧张型头痛患者的第二抑制期(ES2)潜伏期延长,时限缩短,出现率降低(P<0.05)。结论:外感受抑制检查对紧张型头痛具有一定的诊断和研究价值。Objective： To investigate the value of the trigeminal exteroceptive suppression（ES） of temporalis and masseter muscles to examine tnsion-type headache （TTH） sufferers. Methods： The ES was examined in 30 patients with TTH and 30 normal volunteers by electritic stimulation on infraobital region utilizing electromyography（ EMG）, to measure the latency and duration of ES in temporalis and masseter muscles. Results：The onset latency of the second exteroceptive suppression period （ES2） was prolonged and the duration of ES2 was shorter in patients with TTH than those obtained from controls, as well as, the frequency of ES2 was lower（P 〈0.05）. Conclusion： The ES may be useful to diagnose and research in TTH.
