It is obvious that the examination of nerve conduction as a diagnostic aid is a field of interest with the state undergoing evaluation and improvement. This is true particularly in sensory action potential recording.

Conduction study of dorsal ulnar cutaneous nerve was performed with an antidromic technique. Surface recording electrode was placed at the apex of the "V" between the fourth and fifth metacarpal bone, and nerve is stimulated using surface electrodes 9.5 cm above the recording electrode between the flexor carpi ulnaris and the ulnar bone.

90 nerves in 45 normal person were examined. The results were summarized as follows:

1) The sensory conduction velocity of dorsal ulnar cutaneous nerve was 48.11±3.90 meters/sec.

2) The mean value of the latency to the peak of the negative phase was 1.98±0.16 msec.

3) The amplitude of the action potential was 42.96±15.30 uV.

4) NO statistical variation was noted with advancing age in sensory conduction velocity, latency and amplitude of the evoked potential.

5) There were no significant differences related to the dominance of the extremities.
