摘　　要：目的：对桡神经损伤患者的神经肌电图进行分析，探讨其在诊断桡神经损伤中的作用。方法：选择兵团医院2013年9月～2016年9月期间门诊及住院的30例桡神经损伤患者，采用肌电诱发电位仪对患者进行正中神经、尺神经和桡神经的运动及感觉神经传导测定及拇短展肌、小指展肌和指总伸肌针刺肌电图测定，观察所测运动和感觉神经的传导速度及所测肌肉的插入电位、异常自发电位、运动单位电位的波幅、时限和大力收缩时的募集电位。结果：30例桡神经损伤患者的桡神经运动潜伏期延长、传导速度减慢及诱发波幅降低，与正常参考值比较差异有统计学意义；而桡神经感觉神经损害早期绝大多数表现为感觉诱发波幅降低。针刺肌电图检查发现30块指总伸肌中73％出现自发电位，57％出现运动单位时限增宽大于20％，波幅增高大于70％。结论：神经肌电图检测能够为桡神经损伤患者的临床早期诊断、治疗及预后提供可靠依据。Objective：The electromyogram （EMG） of 30 patients with radial nerve injury was ana- lyzed to evaluate the role of electromyography in the diagnosis of radial nerve injury. Methods： 30 patients with radial nerve injury were selected from September, 2013 to September, 2016. Electromyographic e- voked potentials were used to measure the motor and sensory nerve conduction velocity and electromyo- gram of the limbs. The measured muscle movement unit potential of the waveform, amplitude, time limit and strong contraction of the recruitment potential were observed. Results：30 cases of radial nerve injury in patients with radial nerve motor latency, conduction velocity slowed down and evoked amplitude de- creased, and these data were statistically significant, compared with the normal value, while the radial nerve sensation was only manifested as decrease in evoked amplitude. According to EMG 73.3% sponta- neous potential wsa found in 30 cases of extensor digitorum communis, 56.7 % of the movement unit time limit was more than 20 %, the amplitude increased by more than 70 %. Conclusion.. EMG examination may provide reliable evidence for clinical diagnosis on the early stage, treatment and prognosis.
