Effect of Placing the Electrode on the Eyebrow During ENG Recording

Abstract

We have reduced noise markedly during ENG recording of the horizontal aspect of eye movement by placing the electrode on the eyebrow, not above the eyebrow.
Although the noise of frontal muscle electromyography was increased by placing the electrode above the eyebrow, it was decreased markedly by placing it on the eyebrow.
Although this procedure is not the one recommended by the Japan Society for Equilibrium Research, we propose it because it reduces noise markedly.
