摘　　要：目的:探讨肘管综合征(cubital tunnel syndrome,CTS)患者的临床及电生理特点,提高对本病的认识。方法:总结50例CTS患者的患侧(作为患者组)与健侧(作为对照组),将相关的临床及电生理资料进行分析比较。结果:尺神经运动神经传导速度的肘上-肘下段为(33.69±9.31)m/s,潜伏期较对照组延长(7.80±2.58)ms,波幅降低3.5(1.6,8.1)mV;感觉神经传导速度为(48.11±9.51)m/s,潜伏期较对照组延长(2.69±0.61)ms,波幅降低2.8(2.0,4.2)mV,患者组有3例未引出感觉诱发的动作电位波形,其差异均有统计学意义。50例患者肌电图均有异常;50例患者F波有47例表现异常,其中5例未引出。结论:短节段运动神经测定为诊断肘管综合征的可靠手段,可早期确诊及准确定位受损部位及损伤程度。Abstract Objective：To explore the features of cubital tunnel syndrome （CTS） in clinic and electrophysiology through the application of short segmental motor neurological assessment. Methods： Clinical and electrophysiological Documents of 50 patients with CTS were reviewed. And the data of affected side of patients was compared with thatof contralateral side. Results：As compared with control group （contralateral side）, the average conduction velocity of the ulnar never was decreased , the motor conduction velocity （ MCV ） and latency from upper to lower section was （ 33.69 ±9.31 ） m/s and （ 7.80 ±2.58 ） ms respectively ; amplitude of motor action potential was prolonged 3.5 （1.6,8.1） my. The sensory conduction velocity （ SCV ） and latency was （ 48.11 ±9.51） m/s and（2.69± 0.61 ms） respectively ; sensory action potential was prolonged and decreased, amplitude 2.8 （2.0,4.2） my. There was statistically difference between the affected group and healthy control group. The sensory potentials in 3 of the 50 cases could not be elicited. EMG were abnormal in 50 patients. F wave potentials in 5 of the 50 cases could not be elicited, but 47 cases were abnormal. Conclusions： CTS should be diagnosed and treated early if short segmental motor neurological assessment was implicated in patients with CTS in clinic. Electrophysiological examination could provide the reliable evidence for earlier diagnosis of CTS, and exact location and degree of the ulnar never lesions were determined.
