Somatosensory evoked potentials (SEPs) following median nerve stimulation of 25 medical students were recorded along with their height, age and upper limb length. Three major positive and negative peaks were recorded. P1 (16 msec), N1 (20 msec), P2 (28 msec), N2 (33 msec), P3 (43 msec), N3 (50 msec). Significant correlation (P value < 0.05) of N1 and P1 with height and limb length was observed. It is therefore suggested that studies involving SEPs must include physical parameters like age, height and limb length. Our future studies will indicate the accurate correction factor for these physical parameters.
