title: Association between pharyngeal residue and posterior oral spillage with penetration and aspiration in stroke.
abstract: OBJECTIVE
  This study aimed at showing association between the posterior oral spillage and pharyngeal residue with tracheal aspiration and/or laryngeal penetration in stroke.
  
  
  METHODS
  Clinical cross-sectional retrospective multicenter study. The study included 63 videofluoroscopic tests of post-ischemic stroke individuals and oropharyngeal dysphagia data of the three reference centers providing care for patients with dysphagia (43 men and 20 women; age range: from 40 to 90 years). These individuals were divided into two groups. Group I consisted of 35 participants with the presence of penetration and/or laryngotracheal aspiration, and Group II consisted of 28 individuals with no penetration and/or aspiration. Videofluoroscopic swallowing test results were analyzed to divide the groups, and the presence of posterior oral spillage and pharyngeal residue was observed.
  
  
  RESULTS
  No association was found between the groups with posterior oral spillage (χ²=1.65; p=0.30; φ²=0.02), but there was statistical difference for the association between pharyngeal residue (χ²=12.86; p=0.003; φ²=0.20) and the groups.
  
  
  CONCLUSIONS
  There is an association between pharyngeal residue and penetration with tracheal aspiration in post-stroke individuals.
