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 investigate the value of Trigeminal neuralgia and masseter muscle inhibition test (ES) in detecting tension-type headache. Methods ES test was performed in 30 patients with tension-type headache and 30 normal volunteers by stimulating the infraorbital nerve with electromyography (EMG) to detect the latency and time-limit of the temporal and masseter muscles. Results Compared with the control group, patients with tension-type headache had a prolonged latency and a shortened duration in the second phase of inhibition (ES2). The t-test showed that there was significant difference between the left and right temporalis and the masseter EF2 in the tension-type headache group and the control group (P <0.05 or P <0.01). Conclusion Masticatory muscle inhibition test has the value of diagnosis and research on tension-type headache.
