Clinical Trial Summary

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).

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.

Intervention

Procedure:
• The Epley Maneuver
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 Maneuver
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°).

Device:
• Mechanical rotational chair
