简要总结
Unilateral posterior canal benign paroxysmal positional vertigo (BPPV) cases will be randomized to treat with single or multiple cycles of canalith repositioning procedure.The treatment outcomes will be assessed at 7th and 28th days.
详细描述
Patients present with brief episodes of vertigo will be evaluated by Dix-Hallpike test. Cases with positive Dix-Hallpike test, unilateral, posterior canal, will be randomized with block of four. Either single or multiple cycles of canalith repositioning procedure will be performed. Four treatment outcomes will be blindly assessed at 7 and 28 days.

研究组 & 干预措施
Single cycle
single cycle of canalith repositioning procedure
干预措施: Canalith repositioning procedure (Procedure)
multiple cycles of CRP
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
干预措施: Canalith repositioning procedure (Procedure)
结局指标
主要结局
Dix-Hallpike test (DHT)
时间窗: At 7th day
percentage of negative DHT between single and multiple cycles
次要结局
- Dizziness handicap inventory (DHI)(compare to the first visit at 28th day between single and multiple cycles)
- Loss of balance(compare to the first visit at 28th day between single and multiple cycles)
- Dix-Hallpike test (DHT)(At 28th day)
- Subjective symptoms(Improvement of the symptoms compare to the first visit at 28th day between single and multiple cycles)
