摘　　要：目的探讨腕管综合征(CTS)神经电生理特征及其与临床表现的相关性。方法对45例72侧CTS患者进行正中神经的传导速度和电位测定,及拇短展肌、小指展肌的肌电图检查。结果神经电生理检查:正中神经感觉传导速度(SCV)、运动末端运动潜伏期(DML)、运动传导速度(MCV)、感觉神经动作电位波幅(SNAP)、复合肌肉动作电位波幅(CMAP)的异常率分别为100%、71%、45%、85%和67%;肌电图(EMG)检查的异常率高达79%,均与正常参考值有显著差异。结论神经电生理检查是CTS诊断敏感指标。Aim To observe the relativity of the clinical features and electroneurophysiologieal examination in patients with carpal tunnel syndrome（CTS）.Methods Examination of conduction velocity and electric potential of median nerve of 72 nerves in 45 patients with CTS,and electromyogram examination of abductor pollicis brevis and abductor digiti minimi.Results The abnormality rates of five indexes in the electroneurophysiologieal examination including sensory conduction velocity of median nerve（SCV）,distal motor latency（DML）,motor conduction velocity（MCV）,amplitude of the sensory nerve action potential（SNAP） and amplitude of the compound muscle action potential（CMAP） were respectively 100%,71%,45%,85% and 67%.The abnormality rate of electromyogram examination was high up to 79%.Conclusion Electroneurophysiologieal examination is sensitive in diagnosis of CTS.
