The medial antebrachial cutaneous nerve (MACN) is injured infrequently, but due to its anatomical location, it may be injured more frequently than is recognized by injuries and surgical procedures to the elbow and cardiac catheterization. A simple antidromic technique to measure nerve conduction velocity (NCV) of this nerve was developed and used in 40 normal subjects (80 nerves). The nerve was stimulated at the elbow and the evoked potential was recorded by surface disc electrodes from this skin of the medial forearm. The mean NCV for the whole group was 49.3 meters per second. In some cases, NCV were performed on the same subjects by the orthodromic method. Sensory NCV of the MACN was used to confirm injury of this nerve on patients.
