Summary

The aim is to investigate the accuracy of manual diagnostics of benign paroxysmal positional vertigo (BPPV) by comparing it to BPPV diagnostics in mechanical rotational chair (TRV chair). VNG (videonystagmography) goggles will be used in both scenarios. Furthermore, the investigators will examine the importance of angulation and velocity in relation to the diagnostic outcome.

Detailed description

Open-label, randomized controlled trial with cross over comparing manual bedside BPPV diagnostics with diagnostics in a mechanical rotational chair (TRV chair) when using VNG goggles in both scenarios. Patients with a history of positional vertigo will be considered for enrollment and randomized to which diagnostic modality they begin with. Each subject will wait for minimum 30 minutes between the two diagnostics.
