The purpose of this study was to analyze if a daily routine of self-canalith repositioning procedure (CRP) will increase the time to recurrence and reduce the rate of recurrence of benign paroxysmal positional vertigo (BPPV).
Prospective study, nonrandomized control group.
Outpatient clinic.
Thirty-nine patients diagnosed with posterior canal BPPV successfully treated with the CRP. Based on a convenience sample, 17 (44%) patients were assigned to the treatment group, whereas 22 (56%) were assigned to the no-treatment group. The number of subjects lost at the time of follow-up were 5 (29.4%) of the treatment group and 2 (9%) of the no-treatment group.
Patients assigned to the treatment group performed the self-CRP daily, whereas those assigned to the no-treatment group performed no exercises. Patients were followed for up to 2 years.
The main outcome measures were the rate of recurrence of BPPV and the time for BPPV to recur.
Of the 39 subjects, symptoms recurred in 16 (41%) of the total population, 6 (35%) of 17 of the treatment group, and 10 (46%) of 22 of the no-treatment group. There was no difference in the frequency of recurrence (Pearson chi; p = 0.522) or the time to recurrence (survival analysis; log-rank test; p = 0.242).
Our results suggest that a daily routine of the self-CRP does not affect the time to recurrence and the rate of recurrence of posterior canal-BPPV.
本研究旨在分析每日进行自我耳石复位法(CRP)是否会延长良性阵发性位置性眩晕(BPPV)的复发时间并降低其复发率。
前瞻性研究,非随机对照组。
门诊诊所。
39例经CRP成功治疗的后半规管BPPV患者。基于便利抽样,17例(44%)患者被分配至治疗组,22例(56%)患者被分配至非治疗组。随访时治疗组失访5例(29.4%),非治疗组失访2例(9%)。
分配至治疗组的患者每日进行自我CRP,而分配至非治疗组的患者不进行任何锻炼。对患者随访长达2年。
主要观察指标为BPPV的复发率及BPPV复发的时间。
39例受试者中,16例(41%)出现症状复发,其中治疗组17例中有6例(35%)复发,非治疗组22例中有10例(46%)复发。复发频率(Pearson卡方检验;p = 0.522)或复发时间(生存分析;对数秩检验;p = 0.242)无差异。
我们的结果表明,每日进行自我CRP并不影响后半规管BPPV的复发时间和复发率。
