  1. This table shows the minimum (Min), first quartile (1st Qu.), median, third quartile (3rd Qu.), and maximum (Max) values for motor evoked potential (MEP) latencies by mapped muscle and gender (in ms). In the present study, the abductor pollicis brevis muscle (APB), abductor digiti minimi muscle (ADM), flexor carpi radialis muscle (FCR), biceps brachii muscle (BCS), tibialis anterior muscle (TA), and gastrocnemius muscle (GCN) were mapped
