研究概览
简要总结
To assess the Videonystagmographic findings of vertigo patients who don’t have BPPV in indian population.
To recognize or any patterns in VNG which are specific to non BPPV patients.
VNG is a comparatively new modality of Vestibular testing for which we have less data available among indian population. This study aims to bridge that gap .
By scrutinizing such a test which is noninvasive , there might be new scenarios where this test can be used apart from what it is currently being used for.
