Objectives To compare the efficacy of the Epley maneuver with that of a placebo maneuver in patients presenting to the emergency department (ED) with benign positional vertigo (BPV). Methods This was a prospective, randomized, single-blind placebo-controlled trial. Consecutive adult ED patients presenting to a university teaching hospital with BPV were randomized to treatment with either the Epley or placebo maneuver. The severity of vertigo was evaluated on a 0 to 10-point scale before and after the maneuvers. Results Eleven patients were randomized to the Epley group and 11 to the placebo group before the trial was terminated, based on a planned interim analysis. The median decreases in vertigo severity were 6 (95% confidence interval [95% CI]=4 to 9) for the Epley group and 1 (95% CI=0 to 3) for the placebo group (p=0.001). Conclusions The Epley maneuver is a simple bedside maneuver that appears to be more efficacious than a placebo maneuver in the treatment of acute BPV among ED patients.
