To investigate the objective method for electrophysiological examination in evaluating the functional recovery in motor nerve regeneration, 30 rabbits were divided into 5 groups randomly. The common peroneal nerve on left side of every rabbit was sectioned and repaired by epineural suture, while that of the right side was left intact as control. In 2nd, 4th, 8th, 12th and 16th week after operation, the muscle power and the changes of the electrophysiological parameters of the nerve and the muscle were determined dynamically. The linear correlation analysis was used to assess their relationship. The results showed that the electrophysiological parameters and muscle contractibility revealed signs of recovery in parallel. There was a significant linear relationship among the amplitude of the muscle action potential, velocity of nerve-muscle conductivity and muscle contractibility. The conclusion was that the electrophysiological examination of motor nerve and muscle could be used to assess the regeneration of the motor nerve, and it would also reflect the recovery of muscle contactibility in the early stage.
