Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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).
BPPV diagnostic
Supine Roll Test and Dix-Hallpike Test
VNG goggles
Goggles for video nystagmography
IMU sensor
A sensor that measures triaxial acceleration and triaxial angular velocity.
Manual BPPV diagnostics
Bedside BPPV diagnostics
TRV BPPV diagnostics
Diagnostics of BPPV using the TRV chair.
