Stody of level diagnstic value of Inching test on compression peripheral neuritis

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 level diagnostic value of inching test on compression peripheral neuritis. Methods The inching test was Performed at 76 nerves in 58 patients with compression peripheral neuritis. Results There one or more indexes of inching test were abnormal in 65 nerves (85. 5% ). Among them, the positivity rate of amplitude was 78. 9% (60 nerves). The positivity rate of conductive velocity was 52. 6% (40 nerves). These were all higher than the positivity rate Of routine myograph. Conclusions The inching test has impel'tant value in level diagnosis of compression peripheral neuritis. The decrement of amplitude across the lesion have higher positivity rate than the reduction of conductivity velocity.
