The objective of this study was to standardize the technique, increasing the clinical significance of the nerve conduction study in medial and lateral planter 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 medial and lateral planter motor nerves at the ankle and stimulating to the sensory nerves at the toe in 35 healthy Korean adults aged from 22 to 53 years. And then we measured the conduction distance from the stimulating cathode to the active recording electrode in the foot with a flexible tape and a caliper. The mean values of the conduction distance in medial and lateral plantar motor nerves were 7.75±0.85 cm and 8.06±0.97 cm respectively. The mean value of that in medial plantar sensory nerve was 18.3±1.77 cm, too.

The mean value of the distal motor latency was 3.93±0.49 msec for the medial planter nerve and 4.29±0.55 msec for the lateral planter nerve. The mean value of distal sensory latency was 4.30±0.53 msec for the medial plantar nerve and 4.61±0.49 msec for the lateral planter nerve. There was significant difference in the distal latency and amplitude between the medial and lateral plantar motor and sensory nerves.
