VEMP Stimuli: A Guide to Ensuring Patient Safety

Vestibular-evoked myogenic potentials (VEMPs) are electrophysiological measures of saccular and utricular reflex pathways. These potentials are currently the only method available to gain information on these important balance organs in the clinic. VEMPs are recorded easily and have been accepted widely due to the novel information they provide to the vestibular diagnostic evaluation. In most clinics in the United States, VEMPs are recorded using air-conducted short-duration tone bursts or clicks (Rosengren et al, 2009).
