摘要
目的探讨腕管综合征(CTS)患者的神经电生理特征。方法对临床症状、体征符合CTS的60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60例患者中,双侧病变18例,单侧病变42例。60例CTS患者中78条正中神经感觉传导潜伏期均延长和感觉传导速度均减慢,60条正中神经感觉诱发波幅降低,74条正中神经运动远端潜伏期延长,4条正中神经运动远端潜伏期和诱发波幅正常。58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。
Objective To discuss the clinical features of carpal tunnel syndrome（CTS） patients. Methods EMG examination of the median nerve, ular nerve, nerve conduction velocity, extensor pollicis brevis and abductor pollcis longus of 60 cases of CTS patients were examined. Results Among 60 cases of CTS patients, the lesions of 18 cases were bilateral, 42 patients were unilateral. There were all 78 lesions. The latency of 78 median nerves sensory conduction prolonged and the sensory con- duction velocity decreased. Sixty sensory nerves evoked amplitude was reduced. The distal motor latency （DML） of 74 median nerves prolonged. The DML and the evoked amplitude of 4 median nerves were normal. The neurogenie injury was shown in 58 extensor pollicis brevis controlled by the median nerve. Conclusion Clinical features examination has great value in the diagnosis and differential diagnosis of CTS.
