目的研究微移试验对嵌压性单神经病的定位诊断、选择治疗和判断预后的意义。方法对５８例累及运动功能的单神经病患者进行微移试验并随访半年。结果７６条神经中６５条（８５．５％）试验异常，６０条（７８．９％）传导阻滞，４０条（５２．６％）传导减慢。随访发现波幅衰减３０％以下者不需治疗多能恢复，衰减３０％～７０％者中２／３可经非手术方法治愈，而衰减＞７０％时可通过手术松解方法恢复功能。结论微移试验对嵌压性单神经病有重要的定位、选择治疗和判断预后价值。 Objective To study the differential diagnosis of entrapped mononuclear neuropathy localization diagnosis, selection treatment and prognostic significance. Methods Fifty-eight patients with mononeuropathy involving motor function were numerically tested and followed up for six months. Results Of the 76 nerves, 65 (85.5%) had abnormal test, 60 (78.9%) had conduction block and 40 (52.6%) had slow conduction. Follow-up found that 30% of amplitude attenuation less than the recovery without treatment, 30% to 70% of those 2/3 can be cured by non-surgical method, and attenuation of> 70% by surgical release method to restore function. Conclusions The microneedle test has an important role in entrapment-induced mononeuropathy. Choosing treatment and prognostic value.
