Although the cause of MS is not clearly established, one widely accepted theory is otolith asymmetry and canal-otolith conflict. Masseteric vestibular evoked myogenic potentials (mVEMPs) are short latency inhibitory potentials recorded from the bilateral masseter muscle in response to bilateral or unilateral galvanic/acoustic stimuli. Studies have shown that mVEMP evaluates the integrity of the vestibulo-trigeminal pathway and the generator region is the saccule in common with cVEMP.ObjectiveOur study aimed to evaluate the function of the otolith organ and vestibulo-trigeminal pathway in people with high susceptibility to MS via mVEMP.MethodsAccording to the Motion Sickness Susceptibility Questionnaire-Short Form (MSSQ-SF), 21 people with 70-100% susceptibility (high susceptibility) and 20 people with 0-30% susceptibility (low susceptibility) were included in the study.

Gain and saccades were analyzed using a custom MATLAB script. Three VOR gain algorithms were compared: Area under the curve (AUC), instantaneous gain, and regression gain.ResultsIn our sample, no significant differences in the VOR gains were observed between younger and older adults using any of the algorithms. Compared to younger adults, older adults had saccades that were significantly more frequent, of greater amplitude, and of shorter latencies. However, a larger sample size is needed to confirm the lack of aging effect on VOR gains.ConclusionsThe absence of significant effects of aging on VOR gain in vHIT demonstrates that all three gain algorithms should provide similar values for patients across all ages in clinical practice.
