title: Number of maneuvers need to get a negative Dix-Hallpike test.
abstract: Benign Paroxysmal Positional Vertigo is one of the most common causes of dizziness. Its characteristic clinical profile is dizziness at head movements. The main diagnostic maneuver of posterior canal Benign Paroxysmal Positional Vertigo is the Dix-Hallpike test. If the maneuver is positive (vertigo and/or nystagmus), the physician can perform the Epley maneuver on the injured side.
  
  
  OBJECTIVE
  This paper aims at checking the number of maneuvers necessary for patients with posterior canal Benign Paroxysmal Positional Vertigo to have a negative Dix-Hallpike test.
  
  
  METHODS
  we carried out a retrospective analysis of 71 charts of patients with posterior canal Benign Paroxysmal Positional Vertigo, who were treated with the modified Epley maneuver.
  
  
  METHODS
  Cross-Sectional Retrospective.
  
  
  RESULTS
  We found that 76.00% of the patients analyzed had the symptoms completely resolved and negative Dix-Hallpike test with a single maneuver.
  
  
  CONCLUSIONS
  Based on our results it is possible to conclude that the number of modified Epley maneuvers is variable depending on the etiology, being that the Benign Paroxysmal Positional Vertigo secondary to the traumatic brain injury needed a greater number of maneuvers for Dix-Hallpike test to become negative.
