The necessity of post-maneuver postural restriction in treating benign paroxysmal positional vertigo: a meta-analytic study.

The objective of this article is to verify the role of postural restrictions after repositioning maneuvers in treating patients with benign paroxysmal positional vertigo (BPPV). The study included published articles yielded by a Pubmed search concerning post-maneuver postural restriction in treating BPPV. The search was limited to articles published in English language in the last three decades. The search was done on 1/11/2011. For the 18 relevant articles, we applied our inclusion and exclusion criteria and only 9 articles were included. The data collected from each article were statistically analyzed utilizing meta-analytic Review Manager (RevMan 5.1) software. (Version: 5.1.0.0). There were no significant differences between patients instructed with postural restriction after undergoing repositioning maneuver and patients left free to move after undergoing repositioning maneuver with regard to the presence or absence of post-maneuver symptoms. In conclusion, post-maneuver restrictions do not add to the success of the treatment of BPPV and there is no reason to submit patients to these impractical instructions.
