title: Features of Residual Dizziness after Canalith Repositioning Procedures for Benign Paroxysmal Positional Vertigo.
abstract: OBJECTIVE
  To assess factors related to residual dizziness (RD) in patients who underwent successful canalith repositioning procedures (CRPs) for benign paroxysmal positional vertigo (BPPV).
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Academic center.
  
  
  METHODS
  Ninety-seven consecutive patients with BPPV of the posterior semicircular canal were initially enrolled. Diagnosis was assessed according to clinical history and bedside evaluation. All patients were treated with CRPs until nystagmus disappeared. Three days after the successful treatment, presence of RD was investigated. If RD was present, patients were monitored every 3 days until the symptoms disappeared. Subjects who required ≥4 CRPs or who failed to meet the follow-up visit were excluded. The Dizziness Handicap Inventory (DHI) was obtained from patients at the time of diagnosis and at every subsequent visit.
  
  
  RESULTS
  At the end of selection, 86 patients were included; 33 (38.36%) reported RD after successful treatment. A significant difference in the incidence of RD was observed in consideration of the age of the subjects (P = .0003) and the DHI score at the time of diagnosis (P < .001). A logistic regression analysis showed that the probability of RD occurrence increased with the increase of the emotional subdomain score of the DHI questionnaire.
  
  
  CONCLUSIONS
  RD is a common self-limited disorder, more frequent in the elderly, which may occur after the physical treatment for BPPV. The DHI score at the time of BPPV diagnosis represents a useful tool to quantify the impact of this vestibular disorder on the quality of life and to estimate the risk of RD after CRPs.
