[摘要] 目的 探讨腕管综合征(CTS)患者的神经电生理特征及其与临床表现的相关性。方法 对临床症状、体征符合CTS的40例患者进行正中神经、尺神经的运动和感觉传导速度测定，及拇短展肌、小指展肌的肌电图检测。结果 40例患者中，双侧病变28例，单侧病变12例。40例CTS患者中68条正中神经感觉传导潜伏期延长和感觉传导速度减慢，41条正中神经感觉诱发波幅降低，28条正中神经运动远端潜伏期延长，35块正中神经支配的拇短展肌呈神经源性损害。结论 神经电生理检查在CTS的诊断与鉴别诊断中有重要意义。

    [Abstract] Objective To explore carpal tunnel syndrome (CTS) patients nervous eletric physilolgy characteristics and clinical manifestations of relevancy. Methods The clinical symptoms,signs accord with the CTS's 40 patients for the median nerve,the ruler of the motor and sensory nerve conduction velocity measurement, EMG examination of abductor pollicis brevis and electromyography detection. Results Among 40 cases of CTS patients, the lesions of 28 cases were bilateral, 12 patients were unilateral.There were all 68 lesions.The latency of 68 median nerves sensory conduction prolonged and the sensory conduction velocity decreased. Forty one sensory nerves evoked amplitude was reduced.The distal motor latency (DML) of 28 median nerves prolonged, The neurogenic injury was shown in 35 abductor pollicis brevis controlled by the median nerve. Conclusion The seexaminations has great value in the diagnosis and differential diagnosis of CTS. ......
