title: Residual dizziness after successful repositioning maneuvers for idiopathic benign paroxysmal positional vertigo.
abstract: OBJECTIVE
  To establish a possible causal factor for residual dizziness (RD) after successful repositioning maneuvers in patients with benign paroxysmal positional vertigo (BPPV).
  
  
  METHODS
  Ninety consecutive patients with idiopathic BPPV were treated with repositioning maneuvers, and the rate of RD was assessed as well as clinical data. Posturography and assessment of anxiety levels were performed on patients reporting RD. Results were compared with a control group of BPPV patients of the sample after repositioning maneuvers and without RD.
  
  
  RESULTS
  Twenty-eight subjects (31.1%) reported RD on the second day after successful repositioning maneuvers. The mean duration of RD was 11.6 ± 3.9 days. Patients with RD presented a higher duration of BPPV (14.1 vs. 10.9 days, p = 0.01). A correlation was demonstrated between the duration of BPPV and duration of RD (p < 0.01). Subjects with RD presented increased body sways, above all in eyes-closed conditions.
  
  
  CONCLUSIONS
  RD is mainly correlated with duration of vertigo in BPPV patients. Anxiety was demonstrated to play a role in increased body sways.
