Abstract / Description

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 defi ne response presence.
