A simple, reliable method of recording sensory nerve action potentials (SNAP) from the medial and lateral plantar nerves was established using 30 healthy adults as subjects. Potentials were recorded with surface electrodes both antidromically and orthodromically. The mean latency and amplitude of the SNAP of the medial plantar nerve using antidromic stimulation were 2.5msec (+/- 0.32) and 16.3microV (+/- 6.5), respectively. Orthodromically, the latency was 2.5msec (+/- 0.35) and the amplitude 16.5microV (+/- 7.14). For the lateral plantar, antidromically the nerve latency was 2.5msec (+/- 0.35) and the amplitude 14.8microV (+/- 4.41). With the orthodromic procedure, the latency remained unchanged but the amplitude was 11.0microV (+/- 5.59). In the case of the lateral plantar nerve, the antidromic technique consistently resulted in higher amplitude responses.
以30名健康成年人作为研究对象，建立了一种简单、可靠的记录足底内侧神经和足底外侧神经感觉神经动作电位（SNAP）的方法。使用表面电极分别逆向和顺向记录电位。逆向刺激时，足底内侧神经SNAP的平均潜伏期和波幅分别为2.5毫秒（±0.32）和16.3微伏（±6.5）。顺向刺激时，潜伏期为2.5毫秒（±0.35），波幅为16.5微伏（±7.14）。对于足底外侧神经，逆向刺激时神经潜伏期为2.5毫秒（±0.35），波幅为14.8微伏（±4.41）。采用顺向记录方法时，潜伏期不变，但波幅为11.0微伏（±5.59）。对于足底外侧神经，逆向技术始终产生更高的波幅反应。
