Description and Modeling of Swallowing Disorders After a Stroke (AVC-MODE)

The oropharyngeal junction participates in 3 interpenetrating functions: Swallowing, Breathing and Speech. In the context of ischemic or hemorrhagic stroke, these are altered, isolated or associated manner, causing major disorders and representing a source of handicap for patients.

Understanding the swallowing mechanisms is therefore a major challenge to guide the rehabilitation and improve the initial and long-term prognosis of patients with stroke.

The main objective of this study is to describe and modeling, thanks to a clinical, physiological and radiological knowledge base, swallowing, speech and breathing, in patients with stroke and in healthy subjects.
