[Normal electroneurographic values of the sural nerve related to age].
The normal values of sural nerve electroneurography (ENG) by the antidromic technique with skin electrodes are reported for 104 healthy individuals who were evaluated in decade groups. A lineal increase of the duration (DUR) and an increase, also lineal, of amplitude (AMP) of conduction velocity with age were found. Also, a significantly higher AMP of the evoked sensory potential (ESP) was found in the left than in the right side when all data were considered as a whole. The adjustment for age of the parameters of sural nerve ENG is a basic requirement in the measurement of the electrophysiological abnormalities contributing to the diagnosis of a neuropathy.
