摘　　要：目的探讨腕管综合征(CTS)的神经电生理学特点。方法对60例CTS患者及60名正常对照者的神经电生理检查结果进行比较分析。结果 CTS组60例患者98块患侧拇短展肌中39块呈神经源性损害。CTS组60例患者98条患侧正中神经感觉及运动传导均异常。与正常对照组比较,CTS组正中神经感觉神经动作电位(SNAP)潜伏期延长,波幅降低,传导速度减慢;CTS组正中神经运动传导末端潜伏期延长,最大复合肌肉动作电位(CMAP)波幅降低(均P<0.05)。结论 CTS的神经电生理学特点为正中神经SNAP传导速度减慢或SNAP波幅降低,运动传导末端潜伏期延长,拇短展肌呈神经源性损害。Objective To study the features of electrophysiological examination in the carpal tunnel syndrome （CTS）. Methods The result of electrophysiological examination of 60 cases of CTS and 60 normal controls were analyzed. Results In the 98 abductor pollicis brevis of affected side in 60 cases of CTS group, 39 of which were neurogenic damaded. The sensory and motor conduction of 98 median nerves of affected side in 60 cases of CTS group were all abnormal. Compared with normal control group, the latency of sensory nerve action potentials （SNAP） was prolonged, the amplitude of SNAP was decreased, and the conduction velocity of SNAP was slowed in median nerves of CTS group; and the distal latency of motor conduction was prolonged, the amplitude of compound muscle action potentials was decreased in median nerves of CTS group （ all P 〈 0. 05 ）. Conclusion The electrophysiological features of CTS are the slowing of the conduction velocityy of SNAP, the decrease of the amplitude of SNAP and the prolong of the distal motor latency in median nerves, and the neurogrnic damage of abductor pollieis brevis.
