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. Muscle Nerve, 2011
