VEMP: from the origin to the future

Abstract

　VEMP (vestibular evoked myogenic potential) is an electromyographic response originating from the vestibular labyrinth, especially the otolith organ, evoked by sound, vibration, or electrical stimulation. Two types of VEMP, cervical VEMP (cVEMP) and ocular VEMP (oVEMP) have been assessed clinically. In this short review, the author briefly describes the history, basic neurophysiological findings, recording methods, and data interpretation in VEMP testing. Furthermore, the author also discusses the expectations for possible clinical applications of VEMP testing in the near future.
