Abstract

Sensory nerve action potential is always characterized by three factor, amplitude, duration and waveform. In this paper we proposed an additive ratio (median to ulnar sensory nerve action potential amplitudes ratio) for improving the diagnosis of nerve syndrome while measuring sensory nerve action potential (SNAP). Orthodromic median and ulnar SNAPs were recorded and the respective ratios were calculated. Normative data for median nerve SNAP amplitude, ulnar nerve SNAP amplitude and the new ratio is obtained.
