ABSTRACT
INTRODUCTION:
The aim of this study was to explore a method for obtaining sensory nerve action potentials (SNAPs) of the supratrochlear (STN) and supraorbital (SON) nerves and evaluate the function of affected nerves in patients with herpetic ophthalmic neuralgia (HON).METHODS:
Thirty healthy volunteers and 40 subjects with subacute HON participated in this study.RESULTS:
The amplitudes and sensory conduction velocities (SCVs) that predicted HON were identified. The corresponding cutoff values for the amplitudes ranged from 11.10 µV to 12.45 µV. The corresponding cutoff values for the SCVs ranged from 43.14 m/s to 44.64 m/s. SCVs were markedly lower on the affected side compared with healthy volunteers (P < 0.05), and the amplitudes of SNAPs on the affected side were decreased by 36% compared with healthy volunteers (P < 0.05).DISCUSSION:
SCVs of STN and SONs can be obtained with the 3-channel method and used to evaluate myelinated fibers in patients with HON. Muscle Nerve 57 973-980, 2018.Palabras clave
