[The necessity of post-maneuver postural restriction in treating benign paroxysmal positional vertigo].

OBJECTIVE: To evaluate the necessity of postural restrictions after repositioning maneuvers in posterior canal benign paroxysmal positional vertigo (BPPV). METHOD: Sixty-eight consecutive patients diagnosed of posterior canal BPPV with a positive Dix-Hallpike test. Thirty-two patients were instructed to follow postural restrictions after repositioning maneuvers, and 36 patients did not receive any postural restriction after treatment. All the patients were reevaluated at 1 week and 3 months later respectively. RESULT: There was no statistical difference in number of maneuvers needed to resolve symptoms between two groups. CONCLUSION: Epley maneuver is effective to treat patients with posterior canal BPPV, and postural restrictions does not improved the efficacy. Above all, we do not recommend any postural restrictions to patients with posterior canal BPPV.
