Objective: To determine if a daily routine of Brandt-Daroff exercises increases the time to recurrence and reduces the rate of recurrence of benign paroxysmal positional vertigo (BPPV). Design: Random sample of convenience and retrospective case review. Setting: Tertiary referral center and outpatient clinic. Patients: One hundred sixteen patients diagnosed with BPPV involving the posterior semicircular canal (BPPV-PC) who were successfully treated with the canalith repositioning procedure. Interventions: Patients in the treatment group (n=43) performed daily Brandt-Daroff exercises, while patients in the no-treatment group (n=73) performed no exercises. Main Outcome Measures: Follow-up was as long as 2 years. Every 2 months patients were mailed a questionnaire. If BPPV had recurred, patients contacted the principal investigator within 24 hours. Within 1 to 2 weeks, patients were evaluated in the clinic with the Dix-Hallpike maneuver or, if unable to travel to the clinic, interviewed by telephone. Results: Symptoms recurred in 50 (43%) of the 116 subjects, 34 (47%) of 73 in the no-treatment group and 16 (37%) of 43 in the treatment group. There was no significant difference in the frequency of recurrence (Pearson χ2, P=.33) or time to recurrence (survival analysis, log-rank test, P=.92). A history of recurrent BPPV-PC did not affect frequency of recurrence (Pearson χ2, P=.33) or time to recurrence (survival analysis, log-rank test, P=.72). Conclusion: Our results suggest that a daily routine of Brandt-Daroff exercises does not significantly affect the time to recurrence or the rate of recurrence of BPPV-PC.
