About this study
Official title: Efficacy of a New Type of Mechanical Rotational Chair (ROTUNDUM) in Treating BPPV
A study to establish the efficacy of a new type of mechanical rotational chair in treating BPPV. In addition, comparison of three types of treatment maneuvers using the mechanical rotational chair.
Read the detailed description
Open-label, randomized controlled trial comparing three different treatment maneuvers in a mechanical rotational chair (ROTUNDUM-chair) in treating BPPV. Patients diagnosed with BPPV will be randomized to one of three maneuvers in the ROTUNDUM-chair:
- Epley's maneuver
- Semont maneuver
- 360 degree vertical rotation
- Conditions
- BPPV
- Being tested
- Epley's Maneuver, Semont Maneuver, 360 degree vertical rotation
- Keywords
- Benign Paroxysmal Positional Vertigo, Vertigo, Dizziness, Vestibular diseases, Epley Maneuver, Semont Maneuver, Repositioning chair
- Medical subject headings

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of treatments
Number of treatments necessary to achieve resolution of vertigo and nystagmus
Measured: 2 years
Treatment success after first treatment
Number of subjects achieving resolution of vertigo and nystagmus after one treatment
Measured: 2 years
Secondary outcomes (3)
Dizziness Handicap Inventory (DHI) questionnaire
Comparison of pre- and post-treatment score, total score between 0 and 100. Higher score reflects worse condition
Measured: 2 years
Adverse events
Registration of adverse events
Measured: 2 years
Value of liberatory nystagmus
Registration of liberatory nystagmus after each treatment as a prognostic factor for treatment success
Measured: 2 years

Questions about this trial
What is this clinical trial studying?
A study testing Epley's Maneuver, Semont Maneuver and 360 degree vertical rotation in people with 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 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?
Number of treatments (time frame: 2 years). 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 NCT04147156, 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?
