Dynamic evaluation of swallowing in patients with cerebrovascular accident.

To determine the specific effects of cerebrovascular accident (CVA) on deglutition, especially relative to the site of CVA, we studied videotapes of barium swallow examinations in 74 patients who had had a CVA. Although there was no distinct correlation between the prevalence of oral and pharyngeal dysfunction and the site of CVA, left CVA was prone to impair only the oral phase, and right CVA tended to impair both phases.
