title: Repositioning intervals in the modified Epley's maneuver and their effect on benign paroxysmal positional vertigo treatment outcome.
abstract: BACKGROUND
  This study showed that short and long interval treatments achieved comparable success rates. There was no statistically significant difference in the rate of early and late recurrences between the two groups. Modified Epley maneuver can be applied in a short interval time with comparable success and recurrence rates which are as effective as in a long interval time.
  
  
  OBJECTIVE
  The Epley maneuver is called the particle repositioning or canalith repositioning procedure. If a short time interval in each position is effective, it will allow for reduced time and avoid unnecessary physical burden. How long of a stay in each position is not determined in the literature. There is an absence of comparative studies of the BPPV repositioning time. The aim of this study is to compare the treatment time in patients with benign paroxysmal positional vertigo (BPPV).
  
  
  METHODS
  Longitudinal prospective study.
  
  
  METHODS
  Outpatient practice in a tertiary care facility.
  
  
  METHODS
  Sixty consecutive patients with BPPV were included in this study. These patients were sequentially allocated to one of two groups (A or B). The interval times between each position in group A and B were 15 and 120 s, respectively. Modified Epley maneuver was performed in all patients. The maneuvers in both groups were exactly the same sequence of movements, except interval times.
  
  
  RESULTS
  The mean age of the patients was 49.25 years (range =19-76 years). Of the 60 patients, 48 (80%) were women and 12 (20%) were men. Successful outcome was achieved in 26 patients (86.7%) after the first modified Epley maneuver in both groups. Three patients from each group (total six patients) responded to the third modified Epley maneuver and the remaining two patients did not respond to any modified Epley maneuver. Therefore, the Semont maneuver was applied with a successful result.
