摘　　要：目的探讨肘管综合征患者的神经电生理特点。方法总结57例肘管综合征患者的神经电生理资料,与38例正常人(76侧肢体)的神经电生理数据进行分析比较。结果病例组尺神经运动传导速度肘上-肘下段为(34.74±9.57)m/s,复合肌肉动作电位潜伏期较对照组延长,波幅降低,差异有统计学意义(P <0.05)。病例组6侧未引出复合肌肉动作电位,31侧未引出感觉神经动作电位。针极肌电图提示第一骨间背侧肌自发电位出现率77.77%(21/27),小指展肌自发电位出现率84.21%(16/19)。结论神经电生理检测为诊断肘管综合征的可靠手段,可准确定位尺神经受损部位及损伤程度。Objective To investigate the nerve electrophysiological characteristics of patients with cubital tunnel syndrome. Methods Electrophysiological data of 57 patients with cubital tunnel syndrome were collected. And the results were compared with the healthy limbs of 38 healthy people. Results The average conduction velocity of the ulnar nerve decreased, the motor conduction velocity(MCV) from above to below elbow was(34.74±9.57) m/s;the latency and amplitude of compound muscle action potential prolonged and decreased respectively. The difference between the patients group and the healthy control group was statistically significant(P < 0.05). The compound muscle action potential could not be elicited in 6 of the 77 upper limbs, and sensory nerve action potential could not be elicited in 31 of the 77 upper limbs. Electromyography indicated that the spontaneous potential incidence of the first dorsal interosseous muscle was77.77%(21/27), the spontaneous potential incidence of the little finger abductor muscle was 84.21%(16/19). Conclusions Nerve electrophysiological examination could provide the reliable evidence for early diagnosis of cubital tunnel syndrome,and the information for the exact location and degree of the ulnar nerve lesion.
