The objective of this study was to standardize the electrodiagnostic technique, thereby increasing the clinical significance of nerve conduction and somatosensory evoked potential studies in saphenous and lateral femoral cutaneous nerves.

Forty seven healthy adults were studied.

The mean values of the conduction study for saphenous nerve were 2.63±0.21 msec for distal latency, 12.56±2.53㎶ in amplitude, and 1.43±0.16 msec in duration; and all those showing no significant difference in both side and sex, and are not significant correlation with age and skin temperature.

The mean values of the conduction study for lateral femoral cutaneous nerve were 3.03±0.23 msec for distal latency, 7.59±1.75㎶ in amplitude, and 1.37±0.19 msec in duration. All showed no significant difference between both side and no significant correlation with age or height. The only significant difference between the sexes was in amplitude.

The mean value of the P40 latency of somatosensory evoked potential study was 37.32±2.09 msec for the saphenous nerve stimulation and 32.45±1.33 msec for the lateral femoral cutaneous nerve stimulation.

Those all P40 latencies were not significant difference in both side, but were significant correlation with age and height.

Key Words: Saphenous &, lateral femoral cutaneous nerves, SNAP, SSEP
