title: Voluntary Cough and Swallowing Function Characteristics of Acute Stroke Patients Based on Lesion Type.
abstract: OBJECTIVE
  To investigate the relation between voluntary cough and swallowing functions according to the type of lesion in patients with acute stroke.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  University rehabilitation hospital.
  
  
  METHODS
  Acute stroke patients with dysphagia symptoms (N=397).
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  A peak cough flow meter was used to measure voluntary coughing ability. Swallowing function was evaluated using the functional dysphagia scale and the penetration-aspiration scale based on the results of a videofluoroscopic swallowing study. Stroke lesions were divided into one of the following 3 categories: cortical, subcortical, and brainstem. These evaluations were performed within 2 weeks after stroke onset.
  
  
  RESULTS
  Of the enrolled 397 patients, 207 patients were classified as cortical stroke, 106 patients were classified as subcortical stroke, and 84 patients were classified as brainstem stroke. Among the subscores of the functional dysphagia scale, the amount of pharyngeal residue negatively correlated with peak cough flow meter results across all stroke lesion types. In the brainstem lesion, peak cough flow and penetration-aspiration scale scores were high compared with other lesions, but these 2 functions did not show a correlation.
  
  
  CONCLUSIONS
  This study revealed that large amounts of pharyngeal residue correlated with weak voluntary cough ability in all stroke lesion groups. We also showed a discrepancy between 2 functions in the brainstem lesion group. Our results suggest that voluntary coughing exercises could be a helpful therapeutic option for dysphagia to prevent pulmonary complications in some types of patients with stroke.
