• Conditions: Vertigo

• Registration Number: NCT06017466
• Lead Sponsor: Universitair Ziekenhuis Brussel

Brief Summary

The aim of this study is to translate and introduce a cross-cultural adaptation of The Visual Vertigo Analogue Scale (VVAS). E. Dannenbaum et al developed the VVAS in order to diagnose visual vertigo (VV). VV is dizziness caused by visual stimuli such as scrolling through a computer screen or walking through crowds of people or supermarket aisles.

Detailed Description

The Visual Vertigo Analogue Scale (VVAS) was developed by E. Dannenbaum et al in 2011 to diagnose visual vertigo. It is a nine-item analogue scale in which the subjects can rate their symptoms' intensity. The symptoms can be categorized as None (0), Mild (0.1-40), Moderate (40.01-70), or Severe (70.01-100). The VVAS is already available in English and French but a Dutch version does not yet exist. In this study, we would like to translate and introduce a cross-cultural adaptation of the VVAS into Dutch for use with vestibular patients in Belgium.

Arm && Interventions

Group	Intervention	Description
Chronic Vertigo	Visual Vertigo Analogue Scale (VVAS)	Chronic vertigo patients can be divided into three groups. The first pathway is episodic vertigo (caused by e.g. migraine, Ménière's disease, benign paroxysmal positional vertigo (BPPV)) progressively leading to chronic dizziness. The second pathway is initiated by a single attack of vertigo (e.g. neuritis vestibularis) with some initial recovery but later on residual symptoms. The third pathway is the presence of chronic, slowly progressive, continuous, or unchanging symptoms (e.g. bilateral vestibular failure, CNS disorders). All patient with chronic vertigo (see above) will included.
