Abstract

OBJECTIVE: To assess the functional status of the otolithic pathway in vestibular migraine by comparing the results of static and dynamic subjective visual vertical and horizontal [subjective visual vertical (SVV) and subjective visual horizontal (SVH)] testing in patients with vestibular migraine with that of normal individuals.

 

MATERIALS and METHODS: This hospital-based prospective study was conducted in 82 normal adults and 66 adults with vestibular migraine. The SVV and SVH angles were measured under static and dynamic conditions using a software-based test protocol. The arithmetic mean of six readings in each situation was considered. The results were further analyzed by stratifying cases and controls into two age groups 20–40 years and 41–60 years and into gender.

 

RESULTS: The clinical profile of the patients with vestibular migraine was comparable to the available literature. The dynamic SVV and SVH in both age groups and the static SVH in the 41–60 years age group were significantly higher compared to normal individuals (p<0.05). The dynamic SVV and SVH were significantly higher in the cases compared to controls among both males and females (p<0.05).

 

CONCLUSION: There is evidence of otolithic pathway abnormalities in individuals with vestibular migraine. The inclusion of SVV and SVH testing for the evaluation of patients with vestibular migraine may be useful in the interpretation and rehabilitation of symptoms in these patients.
