Evaluation of vestibulo-ocular reflex in motion sickness: A comparison of vHIT, SHIMP, and functional head impulse test

Motion sickness (MS) is an autonomic condition triggered by real or perceived movement. No single objective test reliably identifies MS susceptibility or explains its vestibular basis.ObjectiveTo compare vHIT, SHIMP, and functional head impulse test (fHIT)-with and without optokinetic stimulation-in detecting vestibulo-ocular reflex (VOR) dysfunction in MS, and to examine links between MS susceptibility,...

Comparing vHIT, SHIMP, and the functional head impulse test in motion sickness patients provides useful diagnostic benchmarking, but results should be interpreted cautiously until larger studies confirm which measure best predicts functional outcomes in this population.

Determining the most diagnostically reliable vestibulo-ocular reflex assessment for motion sickness could standardize vestibular evaluation protocols and improve management of a prevalent and often under-diagnosed condition.

1. 01Study directly compares three VOR assessments: vHIT, SHIMP, and the functional head impulse test.
2. 02Patient population is specifically motion sickness sufferers, a distinct and underserved vestibular group.
3. 03Aims to identify which test provides the most reliable diagnostic information.

5. 05Findings may inform vestibular test battery selection in clinical practice.
