Background: Motion sickness (MS) is usually generated when there is a mismatch between the senses which serve balance. One of these senses is related to
vestibular system, so it is highly possible that MS reflects in vestibular test results. But there are some conflicts in correlation between vestibular findings and MS.

Objective: To provide an overview of vestibular tests findings in individuals with MS

Method: Related studies were searched using the words of “motion sickness”, “vestibular test”, and other correlated keywords in the databases of PubMed, Scopus, ProQuest, and Google Scholar. 86 articles with the most correlation were selected to write this review article.

Results: It has been demonstrated that susceptible subjects to different types of MS have more pathologic results in vestibular tests, such as, aye movement
recordings and vestibular evoked myogenic potentials (VEMPs) results, asymmetry ratios and posturography results in particular.

Conclusion: Based on abnormalities in various vestibular tests related to MS, possible contribution of signals from any part of the vestibular organ is likely in sensory conflict and triggering MS. Vestibular test results apparently can separate subjects with different susceptibilities to MS, but it seems difficult to differentiate susceptibilities to various types of MS.
