A prospective randomized controlled study of Li quick repositioning maneuver for geotropic horizontal canal BPPV

Abstract

Background: Li quick repositioning maneuver for treatment of geotropic horizontal canal benign paroxysmal positional vertigo (HC-BPPV) was reported in the literature.

Objective: The aim of this study is to observe the clinical efficacy of the Li quick repositioning maneuver for the treatment of geotropic HC-BPPV.

Methods: The single-blind method was used to conduct a prospective controlled study on 120 patients with geotropic HC-BPPV from May 2014 to May 2017. Patients were randomly assigned to the Li quick repositioning maneuver (Li maneuver) group or the barbecue repositioning maneuver (barbecue maneuver) group.

Results: The successful repositioning rates were 53.3%, 70.4%, 90.7% and 92.3%, respectively, in barbecue maneuver group and 61.7%, 80.7%, 93.0% and 96.3%, respectively, in Li maneuver group at 1-day, 3-day, 1-week and 1-month follow-up. Differences in success rates of repositioning between Li and barbecue maneuver groups at 1 day, 3 days, 1 week and 1 month after initial treatment were not statistically significant using the Kaplan–Meier survival curve with a log-rank test (p = .270) .

Conclusion: The Li maneuver is a rapid, simple and efficacious repositioning method for geotropic HC-BPPV and can be widely applied in clinical practice as an alternative method.

背景：文献报道李氏快速复位操作可治疗向地性水平半规管良性阵发性位置性眩晕（HC-BPPV）。

目的：本研究的目的是观察李氏快速复位操作法治疗向地性HC-BPPV的临床疗效。

方法：采用单盲法对2014年5月至2017年5月120例向地性HC-BPPV患者进行前瞻性对照研究。患者随机分为李氏快速复位操作（李氏操作）组或翻滚复位操作（翻滚操作）组。

结果：在第一天、第三天、第一个星期和第一个月的随访时, 翻滚操作组的成功复位率分别为53.3%、70.4%、90.7%和92.3%；李氏操作组的成功复位率分别为61.7%, 80.7%, 93.0%和96.3% 。使用具有对数秩检验的Kaplan-Meier生存曲线, 在初始治疗后1天、3天、1周和1个月, 李氏操作组和翻滚操纵组之间复位成功率的差异无显著统计学意义（p = .270）。

结论：李氏操作法是一种快速、简单、有效的向地性HC-BPPV复位方法, 可作为临床实践中广泛应用的替代方法。
