About this study
Official title: Treatment of Posterior Benign Paroxysmal Positional Vertigo With Mechanical Rotational Chair: A Randomized Controlled Trial Comparing Epley and 360° Maneuvers.
Comparison of treatment efficacy of Epley maneuver and 360 maneuver in a mechanical rotational chair (TRV chair) in patient with posterior benign paroxysmal positional vertigo (BPPV).
Read the detailed description
Open-label, randomized controlled trial comparing the Epley maneuver with the 360 maneuver using the TRV chair in both scenarios. Patients diagnosed with posterior BPPV will be randomized to receive treatment with either the Epley maneuver or the 360 maneuver.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
The Epley ManeuverProcedure or surgery
5 step procedure where the patient:
- Sits upright in a neutral position
- Rotate 45° towards the affected side around the yaw axis and then ro-tate 135° backward around the pitch axis
- Rotated 90° towards the unaffected side around the yaw axis
- Rotate a further 90° toward the unaffected side around the yaw axis
- Rotates back to an upright position with a 135° backward rotation around the pitch axis.
The 360 Degree ManeuverProcedure or surgery
5 step procedure where the patient:
- Sits upright in a neutral position
- Rotate 45° towards the affected side around the yaw axis and then ro-tate 135° backward around the pitch axis
- Rotate a further 90° backward around the pitch axis (total 225°)
- Rotate a further 90° backward around the pitch axis (total 315°)
- Rotate back to an upright position with an additional 45° backward rota-tion around the pitch axis (total 360°).

What is this clinical trial studying?
A study testing The Epley Maneuver, The 360 Degree Maneuver and Mechanical rotational chair in people with Benign Paroxysmal Positional Vertigo and BPPV, run by Aalborg University Hospital at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Treatment success after first treatment (time frame: 2 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05834452, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2026.
