Abstract

Somatosensory evoked potentials (SEPs) are of value in evaluating the somatosensory pathway from peripheral sensory receptor to cerebral cortex. Scalp-recorded SEPs recorded by median nerve stimulation were investigated in one group (total 23, male 19, female 4) of healthy Korean, and tibial nerve stimulation were studied in another group (total 40, male 34, female 6) of healthy Korean.

1) The Mean latency of the N1, P1, N2, P2, were 14.7±1.32 msec, 18.4±1.24 msec, 23.1±1.62 msec, 31.1±1.9 msec by the right median nerve, and 36.2±2.29 msec, 44.4±2.30 msec, 55.4±3.08 msec, 67.2±3.47 msec by the right tibial nerve.

2) There was no significant difference between right and left sides in the mean latency or amplitude of the median or tibial nerve SPEs.

3) The mean latency of the median or tibial nerve SEPs was increased significantly as the age of subjects was increased. The mean latency of the median or tibial nerve SEPs was increased significantly as the height of subjects was increased.

4) The coefficient of variation of the mean latency of SEPs of all cases were range from 5.16 to 6.32. The coefficient of variation of the mean amplitude of SEPs of all cases were range from 45.69 to 65.16. Narrower dispersion was obtained in the mean latency than amplitude of the median or tibial nerve SEPs.

5) There was no significant correlation between the amplitude of the median or tibial nerve SEPs and the age or height of subjects.

Key Words: Somatosensory evoked potential, Height, Age, Median nerve, Tibial nerve
