Abstract

We present two cases with and without a latency difference of the compound muscle action potential (CMAP) from the abductor digiti minimi (ADM) and the first dorsal interosseous (FDI). In each case, onset latencies of FDI CMAPs using the contralateral small finger as E2 were shorter than those of belly-tendon CMAPs from the ADM and FDI. We conclude that onset of the belly-tendon FDI CMAP does not necessarily indicate initial activation of the FDI.

摘要

我们呈现了两例伴有和不伴有小指展肌（ADM）和第一骨间背侧肌（FDI）的复合肌肉动作电位（CMAP）潜伏期差异的病例。在每种情况下，使用对侧小指作为 E2 记录的 FDI CMAP 的起始潜伏期均短于 ADM 和 FDI 腹肌腱 CMAP 的潜伏期。我们得出结论，腹肌腱 FDI CMAP 的起始并不一定表明 FDI 的初始激活。
