咀嚼肌外感受抑制试验在紧张型头痛患者中的应用

Application of Exteroceptive Suppression of the Masticatory Muscles Electromyography Activity in Patients with Tension-type Headache

目的探讨三叉神经颞肌、咬肌外感受抑制试验(ES)检测紧张型头痛的应用价值。方法对30名紧张型头痛和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、咬肌的潜伏期和时限。结果与对照组相比,紧张型头痛患者的第2抑制期(ES2)潜伏期延长,时限缩短现象。经t检验,紧张型头痛组左右侧颞肌和咬肌EF2潜伏期、左侧颞肌时限与对照组比较,差异有统计学意义(P<0.05或P<0.01)。结论咀嚼肌外感受抑制试验对紧张型头痛具有诊断和研究价值。

[Objective]To study the application value of exteroceptive suppression（ES） of the temporalis and masseter muscles in detection of tension-type headache（TTH）.[Methods]The ES was performed in 30 TTH patients and 30 normal volunteers by conducting electrical stimulation on infraorbital nerve with electromyography（EMG）,the latency and duration of temporalis and masseter muscles were tested.[Results]Compared with the control group,the latency of second exteroceptive suppression period（ES2） of TTH patients was prolonged,and the duration was shortened.The t test showed that there were significant differences in latency of ES2 of bilateral temporalis and masseter muscles,and duration of left temporalis muscles between the TTH group and the control group（P0.05 or P0.01）.[Conclusion]The ES of masticatory muscles has the diagnostic and research value in TTH.
