Lokesh Kumar Penubarthi, Bhaskar Thakur

Abstract :

Introduction: Subjective visual vertical is a function of otolith organs. There were many publications over the measurement of subjective visual vertical in laboratory set up. In this article , subjective visual vertical was measured by a simple, easily made bucket method. Materials and methods:Thirty normal subjects with no previous complaints of vertigo were compared with fifteen patients with acute vertigo with this bucket method. Results and conclusion:Subjective Visual Vertical test ( SVV) at a cutoff value of 1.30 demonstrating 100% sensitivity and 100 % specificity . We recommend the use of bucket method for measurement of SVV in patients with vertigo in routine neurotological examination.
