Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests whether two mechanical rotation chairs—the TRV and the newer Rotundum—are equally accurate at diagnosing benign paroxysmal positional vertigo (BPPV), a common cause of brief dizzy spells triggered by head movements. About 200 adults with typical BPPV symptoms will undergo diagnostic maneuvers in both chairs, and results will be compared using two international diagnostic criteria. The goal is to see if the chairs agree on which inner ear canal is affected and the specific BPPV subtype, which could help clinics choose the best tool for precise diagnosis.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Two mechanical rotation chairs (TRV and Rotundum) used for diagnostic positioning maneuvers
What this could lead to
If one chair proves as accurate as the other, clinics could choose the more portable or affordable option without compromising BPPV diagnosis.
What could go wrong
The study is relatively small and compares two devices, so results may not apply to all rotation chairs. Differences in design could still affect diagnostic accuracy.
