Detailed Description

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

Open-label, cross-sectional prospective study examining the prevalence of positional nystagmus in healthy adults (adult with no previous or current inner ear disease) using a mechanical repositioning chair (TRV-chair, Interacoustics, Middelfart, Denmark). Patients will undergo traditional testing related to positional nystagmus by means of both the Dix-Hallpike test and Supine Roll Test (SRT) bilaterally. Latency, duration, and slow phase velocities will be registered and examiner as well as order of the positional tests performed with the TRV chair will be block randomized.
