Treatment of benign paroxysmal positional vertigo (BPPV) with the Epley and Semont maneuvers has been used with and without postmaneuver postural restrictions. Studies examining these restrictions have yielded differing results. This study sought to examine the studies for a more uniform conclusion.
Controlled studies with objective identification of unilateral posterior semicircular canal BPPV and symptom resolution were analyzed. A PubMed search identified six studies totaling 523 patients meeting all inclusion criteria.
Cohorts treated with and without restrictions were compared. Individual patient pooled analyses in a one-stage comparison were used for the meta-analysis.
Pooled results of all restriction types showed no advantage over no restriction. Studies including each individual restriction were examined against the pooled population to look for technique differences. No restriction was found to be statistically significant.
The restrictions examined in controlled trials did not differ significantly in clinical outcomes, which suggests that restrictions do not appear to significantly affect the efficacy of BPPV maneuvers.
采用 Epley 和 Semont 手法治疗良性阵发性位置性眩晕（BPPV）时，可在进行手法治疗后限制患者的姿势，也可不限制患者的姿势。研究这些限制因素的结果存在差异。本研究旨在对这些研究进行更统一的分析。
分析了使用 Epley 和 Semont 手法治疗并客观确定单侧后半规管 BPPV 患者和症状缓解情况的对照研究。通过 PubMed 搜索，确定了符合所有纳入标准的 6 项研究，共 523 例患者。
对有和无限制的患者进行比较。采用单阶段比较对个体患者进行汇总分析，以进行荟萃分析。
所有限制类型的汇总结果均未显示出优于无限制的优势。对纳入的每个限制因素进行研究，与汇总人群进行比较，以寻找技术差异。未发现任何限制因素具有统计学意义。
在对照试验中检查的限制因素在临床结果上没有显著差异，这表明限制因素似乎不会显著影响 BPPV 手法治疗的效果。
