The topic of this article is probably unfamiliar to most electromyographers. These potentials can be seen at high amplification immediately preceding the median or ulnar compound muscle action potential (CMAP) during standard motor nerve conduction studies. A chronological review of premotor potentials is provided. After longstanding debate, eventual determination of their electrophysiologic origin employed analysis of these potentials using volume conduction principles. The significance of premotor potentials is addressed.
本文的主题可能大多数肌电图学家都不熟悉。在标准运动神经传导研究中，在正中神经或尺神经复合肌肉动作电位（CMAP）之前的高放大倍数下可以看到这些电位。本文对运动前电位进行了按时间顺序的综述。经过长期争论，最终利用容积传导原理对这些电位进行分析确定了它们的电生理起源。文中探讨了运动前电位的意义。
