[The record of sensitive nerve action potentials. Interelectrode distance in healthy children].

Background: Studies in adults show that with a 3 or 4 cm distance between active and reference electrodes, maximum amplitude and latency values of sensitive nerve action potentials are obtained. The purpose of this study was to identify, in healthy children, the interelectrode distances at which the amplitude and peak latency do not differ significantly from those obtained with the intereletrode distance at which the maximum values are obtained.

Methods: Four reference electrodes were placed at 1, 2, 3 and 4 cm distance from the active electrode.
