What is it about?

Stroke survivors are at risk for swallowing impairment (dysphagia) with most of the research focusing on swallowing problems in the mouth and throat. However, swallowing is an act that involves the mouth, throat, and the esophagus (food pipe). We studied post-stroke Modified Barium Swallow (x-ray swallow tests) and found that more than half of the patients had evidence of abnormal clearance of swallowed material through their esophagus.

Why is it important?

This is an important finding as esophageal swallowing impairments may be overlooked post-stroke.


We were interested in exploring the possibility that swallowing impairments may extend beyond the mouth and throat in stroke survivors.
