    Abstract:
    IMPORTANCE: Questions remain concerning treatment efficacy for the common condition of benign paroxysmal positional vertigo (BPPV). OBJECTIVE: To compare the effectiveness of the Semont-plus maneuver (SM-plus) and the Epley maneuver (EM) for treatment of posterior canal benign paroxysmal positional vertigo (pcBPPV) canalolithiasis. DESIGN, SETTING, AND PARTICIPANTS: This prospective randomized clinical trial was performed at 3 national referral centers (in Munich, Germany; Siena, Italy; and Bruges, Belgium) over 2 years, with a follow-up to 4 weeks after the initial examination. Recruitment took place from June 1, 2020, until March 10, 2022. Patients were selected randomly during routine outpatient care after being referred to 1 of the 3 centers. Two hundred fifty-three patients were assessed for eligibility. After consideration of the exclusion criteria as well as informed consent, 56 patients were excluded and 2 declined to participate, with 195 participants included in the final analysis. The analysis was prespecified and per-protocol. INTERVENTIONS: After being randomized to the SM-plus or the EM group, patients received 1 initial maneuver from a physician, then subsequently performed self-maneuvers at home 3 times in the morning, 3 times at noon, and 3 times in the evening. MAIN OUTCOME AND MEASURES: Patients had to document whether they could provoke positional vertigo every morning. The primary end point was the number of days until no positional vertigo could be induced on 3 consecutive mornings. The secondary end point was the effect of the single maneuver performed by the physician. RESULTS: Of the 195 participants included in the analysis, the mean (SD) age was 62.6 (13.9) years, and 125 (64.1%) were women. The mean (SD) time until no positional vertigo attacks could be induced in the SM-plus group was 2.0 (1.6) days (median, 1 [range, 1-8] day; 95% CI, 1.64-2.28 days); in the EM group, 3.3 (3.6) days (median, 2 [range, 1-20] days; 95% CI, 2.62-4.06 days) (P = .01; α = .05, 2-tailed Mann-Whitney test). For the secondary end point (effect of a single maneuver), no significant difference was detected (67 of 98 [68.4%] vs 61 of 97 [62.9%]; P = .42; α = .05). No serious adverse event was detected with both maneuvers. Nineteen patients (19.6%) in the EM group and 24 (24.5%) in the SM-plus group experienced relevant nausea. CONCLUSIONS AND RELEVANCE: The SM-plus self-maneuver is superior to the EM self-maneuver in terms of the number of days until recovery in pcBPPV.
