Effects of Background Composition, Tilt, and Rotation on Accuracy of the Subjective Visual Vertical

Overview

About this study

The primary goal of this proposal is to investigate the effects of background content on subjective visual vertical (SVV) error in patients with persistent (>3 months) vertigo, unsteadiness, or dizziness due to neuro-otologic disorders and normal individuals. The secondary goal is to correlate SVV errors with standardized measures of discomfort with space-motion stimuli, dizziness handicap, anxiety, body vigilance, neuroticism, and introversion, all of which have been identified as risk factors or core elements of persistent vestibular symptoms.
