摘　　要：本文对兔坐骨神经钳夹伤后的电生理研究结果表明：１．神经损伤后第１０天肌电图（ＥＭＧ）表现有插入电位延长，延长时间随神经再生而逐渐缩短。２．损伤后第２０天可记录到再生小电位。３．诱发肌肉收缩电位于神经损伤后３０天可记录到，４．推算神经再生速度平均为２．８３ｍｍ／日，最快可达４ｍｍ／日。本研究旨在对神经再生的临床判断及有关研究提供参考。In this article, the results of electrophysiological study on rabbit sciatic nerve after clamp injury indicated that firstly there were prolongation of insertion potential of EMG ten days after injury of the nerve, the duration shortened gradually along with regeneration of the nerve. Secondly, regeneration small potentials could be recorded at 20 days post-traumatically. Thirdly,induced muscular contraction potentials could be recorded 30 days after nerve injury. Fourthly,the average standard nerve regeneration velocity was 2.93mm/day,the utmost being 4mm/day.The aim of study is to offer a clinical criteria of nerve regeneration and a reference of related researches.
