Outcome Measures

Primary Outcomes (1)

  • Dix-Hallpike test (DHT)

    percentage of negative DHT between single and multiple cycles

    At 7th day

Secondary Outcomes (7)

  • Dizziness handicap inventory (DHI)

    compare to the first visit at 7th between single and multiple cycles

  • Dizziness handicap inventory (DHI)

    compare to the first visit at 28th day between single and multiple cycles

  • Subjective symptoms

    Improvement of the symptoms compare to the first visit at 7th day between single and multiple cycles

  • Subjective symptoms

    Improvement of the symptoms compare to the first visit at 28th day between single and multiple cycles

  • Loss of balance

    compare to the first visit at 7th between single and multiple cycles

  • +2 more secondary outcomes

Study Arms (2)

Single cycle

EXPERIMENTAL

single cycle of canalith repositioning procedure

Procedure: Canalith repositioning procedure

multiple cycles of CRP

EXPERIMENTAL

multiple cycles of canalith repositioning procedure CRP will be stopped if 1) no nystagmus and vertigo in all positions 2) complications exited 3) stable nystagmus in the 2 last cycles

Procedure: Canalith repositioning procedure

Interventions

Canalith repositioning procedure; single or multiple cycles

Also known as: Epley's maneuver
Single cyclemultiple cycles of CRP
