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:

    1. Sits upright in a neutral position
    2. Rotate 45° towards the affected side around the yaw axis and then ro-tate 135° backward around the pitch axis
    3. Rotated 90° towards the unaffected side around the yaw axis
    4. Rotate a further 90° toward the unaffected side around the yaw axis
    5. 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:

    1. Sits upright in a neutral position
    2. Rotate 45° towards the affected side around the yaw axis and then ro-tate 135° backward around the pitch axis
    3. Rotate a further 90° backward around the pitch axis (total 225°)
    4. Rotate a further 90° backward around the pitch axis (total 315°)
    5. Rotate back to an upright position with an additional 45° backward rota-tion around the pitch axis (total 360°).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Treatment success after first treatment

    Number of subjects achieving resolution of vertigo and nystagmus after one treatment

    Measured: 2 year

  2. Number of treatments

    Number of treatment necessary to achieve resolution of vertigo and nystagmus

    Measured: 2 year

Secondary outcomes (3)
  1. Dizziness Handicap Inventory (DHI) Questionnaire

    Comparison of pre-treatment score and post-treatment score

    Measured: 2 year

  2. Adverse events

    Registration of adverse events

    Measured: 2 year

  3. Recurrence rate

    Recurrence of BPPV 3 and 6 months after successful treatment.

    Measured: 2 year
