摘　　要：目的探讨颈源性头痛(CH)患者头颈部肌肉触痛点针肌电检查的意义。方法对CH患者22例(头痛组)和非头痛正常人5例(对照组)行传统同心圆针电极肌腹插入检查,记录并分析双侧头夹肌及颞肌共4个部位的异常放电频率和波幅。结果不同头痛部位肌电异常诊断CH的灵敏度为60%-100%,特异度为66.7%-100%;但不同头痛部位的结果无统计学差异。对照组肌电检查结果均未见异常放电。结论 CH患者疼痛部位可有明显的肌电改变,但存在一定比例的假阳性和假阴性结果,触痛点针肌电检查是否可作为临床诊断的客观指标尚需进一步研究。Objective To investigate the significance of muscle tenderness point needle electromyographic（EMG）examination in the patients with cervicogenic headache（CH）.Methods Muscle tenderness point needle EMG examination was performed in the patients with CH（group A,22cases）and healthy people（group B,5cases）.Abnormal discharge frequency and amplitude in 4parts of muscles（the bilateral splenius capitis muscle and temporalis）in group A were recorded and analyzed by screening test.Results The sensitivity and specificity for the EMG to diagnose CH were 60.0%-100% and 66.7%-100%,respectively,which were not significantly different among 4parts of muscles in group A.No any abnormal discharge was seen in group B.Conclusion Abnormal EMG changes can be seen in pain point of the patients with CH and there is a certain percentage of false negative and false positive.Further studies are needed to check whether the tender point needle EMG is a valuable indicator for the clinical diagnosis of CH.
