The origin of the intramuscular nerve action potential (INAP) was investigated using conventional surface recording electrodes. The appearance of the INAP was (1) associated with subjective paresthesias, (2) recorded only when the reference electrode (G2) was over an appropriate digital nerve, (3) increased in latency as G2 was placed more distally, (4) blocked by an orthodromic sensory nerve action potential arising from the thumb, and (5) abolished with an anaesthetic block in the digital nerve proximal to G2. The findings indicate that the INAP is recorded by the G2 electrode from the digital nerve.
使用传统的表面记录电极对肌内神经动作电位（INAP）的起源进行了研究。INAP的出现具有以下特点：（1）与主观感觉异常相关；（2）仅当参考电极（G2）置于合适的指神经上方时才能记录到；（3）随着G2向更远端放置，潜伏期延长；（4）被来自拇指的顺行性感觉神经动作电位阻断；（5）在G2近端的指神经进行麻醉阻滞时消失。这些发现表明，G2电极记录到的INAP来自指神经。
