[] 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 edian 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 edian nerves sensory conduction prolonged and the sensory conduction velocity decreased. Forty one sensory nerves evoked amplitude otor latency (DML) of 28 median nerves prolonged, The neurogenic injury edian nerve. Conclusion The seexaminations has great value in the diagnosis and differential diagnosis of CTS.

腕管综合征(Carpal tunnel syndrome, CTS),是正中神经在腕管内受压而引起的手指感觉异常为主要特征的一种症候群,是嵌压性周围神经病中最常见的一种。当局部骨折脱位、韧带增厚或管内的肌腱肿胀、膨大引起腕管相对变窄,致使腕部正中神经慢性损伤产生腕管综合症。CTS的特征性神经电生理改变,即神经传导检测主要显示腕远侧节段正中神经感觉或(和)运动传导的选择性异常,而同侧尺神经远侧节段及正中神经近段相对正常[1]。现将我们诊断的40例CTS患者的临床及神经电生理资料分析报道如下。
