Since the first description of sound-evoked short-latency myogenic reflexes recorded from neck muscles, vestibular evoked myogenic potentials (VEMPs) have become an important part of the neuro-otological test battery. Recent research has shown that VEMPs can also be recorded from the extraocular muscles using surface electrodes placed near the eyes. These “ocular VEMPs” (oVEMPs) are a manifestation of the vestibulo-ocular reflex. Both cervical and ocular VEMPs provide a means of assessing otolith function. In this workshop the historical development of the oVEMP, its neurophysiological properties and characteristics in central and peripheral disorders of vestibular function will be described.
