Objectives/Hypothesis: The need for class I and II studies on the efficacy of liberatory maneuvers in the treatment of lateral canal benign paroxysmal positional vertigo (LC-BPPV) motivated the present double-blind randomized trial on the short-term efficacy of the forced prolonged position (FPP). Study Design: Double-blind, randomized controlled trial. Methods: Two hundred twenty-one patients with unilateral LC-BPPV met the inclusion criteria for a multicentric study. Patients were randomly assigned to treatment by FPP (116 subjects) or sham treatment (105 subjects). Subjects were followed up at 24 hours with the supine roll test by blinded examiners. Results: Among the sample, 67.4% and 32.6% of the patients showed respectively geotropic and apogeotropic variant of LC-BPPV. At the 24-hour follow-up, the effectiveness of FFP compared to the sham maneuver was, respectively, 57.8% versus 12.4% (P <.0001) in the total sample, 76.9% versus 11.3% (P <.0001) in the geotropic variant group, and 60.5% versus 17.6% (P =.0003) in the apogeotropic variant group, including resolution or transformation to geotropic variant. Conclusions: FPP proved highly effective compared to the sham maneuver. The present class 2 study of the efficacy of the FPP changes the level of recommendation of the method for treating LC-BPPV into a strong one. Level of Evidence: 2 Laryngoscope, 2020.

Abstract

Objectives/Hypothesis: The need for class I and II studies on the efficacy of liberatory maneuvers in the treatment of lateral canal benign paroxysmal positional vertigo (LC-BPPV) motivated the present double-blind randomized trial on the short-term efficacy of the forced prolonged position (FPP). Study Design: Double-blind, randomized controlled trial. Methods: Two hundred twenty-one patients with unilateral LC-BPPV met the inclusion criteria for a multicentric study. Patients were randomly assigned to treatment by FPP (116 subjects) or sham treatment (105 subjects). Subjects were followed up at 24 hours with the supine roll test by blinded examiners. Results: Among the sample, 67.4% and 32.6% of the patients showed respectively geotropic and apogeotropic variant of LC-BPPV. At the 24-hour follow-up, the effectiveness of FFP compared to the sham maneuver was, respectively, 57.8% versus 12.4% (P <.0001) in the total sample, 76.9% versus 11.3% (P <.0001) in the geotropic variant group, and 60.5% versus 17.6% (P =.0003) in the apogeotropic variant group, including resolution or transformation to geotropic variant. Conclusions: FPP proved highly effective compared to the sham maneuver. The present class 2 study of the efficacy of the FPP changes the level of recommendation of the method for treating LC-BPPV into a strong one. Level of Evidence: 2 Laryngoscope, 2020.
