The objective of this study was to standardize the technique, increasing the clinical significance of the nerve conduction study in median and ulnar motor and sensory nerves.

At first we found the stimulating point that the muscle action potentials or nerve action potentials are most definitely elicited after stimulating to the median and ulnar nerves at the wrist in 44 healthy Korean adults aged from 20 to 49 years. And then we measured the conduction distance from the stimulating cathode at the wrist to the active recording electrode in the hand muscle or the finger in the median and ulnar nerves respectively.

The mean values of the conduction distance in median and ulnar motor nerves were 6.0±0.60 cm and 5.3±0.54 cm respectively. The mean values of that in median and ulnar sensory nerves were 13.3±1.12 cm and 11.6±0.82 cm respectively, too.

There was statistically significant correlation between the height of the volunteer and the conduction distance in median and ulnar, motor and sensory nerves(p<0.01).

Key Words: Median nerve, Ulnar nerve, Nerve conduction study, Conduction distance
