Electroneurography index: A standardized neurophysiological method to assess peripheral nerve function in patients with polyneuropathy

Abstract

An index based on 12 electrophysiological parameters (conduction velocities, F‐latencies, and amplitudes) was constructed to obtain an overall estimation of peripheral nerve conduction. The index was expressed as the meandeviation (in SD) compared to controls standardized for age or height. The stability of the index was tested by repeated examinations during intervalsof several months in healthy subjects. The use of a compound index enabled detection of slight impairments of nerve conduction. The relatively low interrecording variability of the index makes it suitable to follow the progression of a polyneuropathy. © 1993 John Wiley & Sons, Inc.
