Simultaneous four‐channel recording of bilateral cervical and ocular vestibular‐evoked myogenic potentials in response to stimulation by forehead bone‐conducted vibration: Our experience in 20 healthy adults

Abstract

Various vestibular stimuli, including air‐conducted sound (ACS), bone‐conducted vibration (BCV), and galvanic vestibular stimulation (GVS), can be used to elicit vestibular‐evoked myogenic potential (VEMP). VEMP obtained from the sternocleidomastoid (SCM) muscle is called cervical VEMP (cVEMP), while that recorded at extraocular muscles is termed ocular VEMP (oVEMP). cVEMP was first recognized as fundamental in determining the sacculo‐collic reflex (SCR) pathway in the mid‐1990s. In the mid‐2000s, oVEMP was successfully recorded and emerged as the basis for a promising examination for evaluating the integrity of the vestibulo‐ocular reflex (VOR) pathway.
