简要总结
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.
详细描述
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.

研究组 & 干预措施
Bedside BPPV diagnostics
Diagnostics of BPPV with manual tests using VNG goggles. The goggles will be added an IMU sensor detecting angulation and velocity (the physician will not get feedback from the sensor during the examination. This will only be used in later analysis).
干预措施: BPPV diagnostic (Diagnostic Test)
