Nestle: Session 4

International Course on Oropharyngeal Dysphagia

Session#4:  Understanding Rheology and Approaches for Swallow Rehab & Treatment

Course Description

Session 4 begins with a lecture regarding the basic principles of rheology and how those principles are intrinsically linked to dysphagia management. Dr. Hanson reviews basic concepts of bolus flow and force with respect to individual stages of the oro-pharyngeal swallow and how these principles functionally impact safe swallowing ability. Basic tenants related to texture modification including stability, consistency and uniformity were reviewed.  Dr. Martino provides a detailed review of the literature exploring the relationship between dysphagia in stroke patients and the development of pneumonia.  She clearly delineates how methods of patient assessment impact reported pneumonia rates with overall prevalence ranging from 45-73%. Her comprehensive efforts reveal the need for future studies that further explore this complicated relationship and expand into additional financial, social and emotional ramifications of dysphagia in stroke patients.
