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.

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:

1. Epley's maneuver
2. Semont maneuver
3. 360 degree vertical rotation

Inclusion Criteria:

• Characteristic (for BPPV) positional nystagmus
• Positive Dix-Hallpike Test
• Medical history compatible with BPPV

Exclusion Criteria:

• Treatment in a mechanical rotational chair within the last 6 months
• Exclusion of BPPV diagnosis
• Lack of treatment cooperation
• Known cerebral aneurism or cerebral hemorrhage
• Treated for BPPV within the past month
