Physiological Flow of Liquids in Healthy Swallowing
In Brief
An observational study evaluating Starch-thickened liquids, Xanthan-gum thickened liquids, and 1 other intervention for Deglutition and 2 related conditions. Completed, enrolled 80 participants across 1 site.
Detailed Summary
Thickened liquids are commonly used as an intervention for people with dysphagia (swallowing impairment). However, the field currently lacks a proper understanding of how this intervention works. The overall goal of the project is to collect measurements of bolus flow through the oropharynx (i.e., mouth and throat) during swallowing. The factors that are expected to influence bolus flow include the liquid/food consistency (i.e., thin, slightly-thick, mildly-thick, moderately-thick, extremely thick, solid) and the forces applied during swallowing (i.e., tongue pressures and swallowing muscle contraction). The objective is to determine how these factors interact to influence the flow of a bolus through the oropharynx in healthy swallowing.
