More than 400 patients have been reported in blinded studies comparing the Epley or Semont maneuver to either placebo or medical treatment. The results are clearly in favor of these maneuvers. The median response in treated patients was 81%, compared to 37.% in placebo or untreated subjects. The few instances where the Epley or Semont results were not compelling (e.g. Blakely et al, 1994), may have been instances where technique was not perfected.

Helminski et al (2010) recently published a meta-analysis of CRP in posterior canal BPPV. They concluded that there was very good evidence for efficacy of the Epley maneuver.
