    Abstract

    Objective: To evaluate methods for estimating thresholds of vestibular evoked myogenic potentials (VEMPs) and ocular VEMPs (OVEMPs) produced by impulsive transmastoid acceleration (ITA). Design: VEMPs and OVEMPs were obtained simultaneously from subjects in supine posture with both head and eyes elevated. Thresholds to ITA were measured using four different response identification methods. Study sample: Twelve adult subjects with no history of auditory or vestibular deficits. Results: VEMP and OVEMP thresholds were found within the range of -8 to -26 dB re 0.2 g, with overall VEMP thresholds being lower than OVEMP thresholds by average of 3-10 dB, depending on the method used. Conclusion: VEMPs can be obtained at lower ITA stimulation levels than OVEMPs. Threshold values depend on the method used to define response presence. © 2014 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.
