Abstract

The use of single fiber EMG and macro EMG in studies of reinnervation is discussed. SFEMG gives information about changes in the topography of the motor unit and in function of transmission in terminal nerve, motor endplate and muscle fiber. Dynamics of reinnervation may be studied with this technique. The amount of reinnervation is obtained from macro EMG studies. The capacity for reinnervation is discussed for a few conditions as well as factors that limit the reinnervation process.

摘要

本文讨论了单纤维肌电图和巨肌电图在神经再支配研究中的应用。单纤维肌电图可提供有关运动单位拓扑结构变化以及终末神经、运动终板和肌纤维中传导功能变化的信息。利用该技术可研究神经再支配的动态过程。神经再支配的程度可通过巨肌电图研究获得。本文还讨论了几种情况下的神经再支配能力以及限制神经再支配过程的因素。
