Video-head impulse test results in patients with Menière's disease related to duration and stage of disease.

Background: The video-head impulse test employs the vestibulo-ocular reflex (VOR) to assess vestibular function. To this day, no consensus has been reached among scientists in terms of whether or not vHIT results change in MD patients as the disease progresses.

Objective: To assess whether the vHIT is more often abnormal in later stages of MD compared to earlier stages.
