紧张型头痛及偏头痛患者咀嚼肌外感受抑制试验研究

Study of exteroceptive suppression of masticatory muscles electromyography activity in patients with tension-type headache and migraine

目的探讨三叉神经颞肌、咬肌外感受抑制试验(ES)检测紧张型头痛及偏头痛的应用价值。方法对30例紧张型头痛患者、30例偏头痛患者及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。结果与对照组及偏头痛组相比,紧张型头痛患者的第二抑制期(ES2)潜伏期延长,时限缩短(P<0.05)。结论 ES对紧张型头痛及偏头痛具有诊断和研究价值。

Objective It is to investigate the value of trigeminal exteroceptive suppression（ES） of temporalis and masseter muscles to examine tension-type headache（TTH） and migraine sufferers.Methods The ES was examined in 30 patients with TTH,30 patients with migraine,and 30 normal volunteers by electric stimulation on infraobital region utilizing electromyography（EMG）.The latency and duration of ES in temporalis and masseter muscles were measured.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 migraine or controls（P〈0.05）.Conclusion The ES may be useful to diagnose and research in TTH and migraine.
