Reference Values for Videofluoroscopic Measures of Swallowing
Sponsor: University Health Network, Toronto
Summary
Dysphagia (swallowing impairment) is a serious health condition seen in many age-related disease and injury processes. Although videofluoroscopy (VF) is an international "gold standard" dysphagia diagnostic exam, there is a paucity of available normative physiologic VF reference values in healthy adults across the age span to guide interpretation of these examinations. In this project, the investigators will extend previous work on the quantitative measurement of swallowing physiology from VF examinations to establish reference values for swallowing in healthy adults, and to identify clinical decision point values for differentiating healthy swallowing across the age span from disordered swallowing in several high-risk clinical populations to study dysphagia.

Videofluoroscopic Swallowing Study (VF)
A videofluoroscopy (VF) is a dynamic radiological evaluation of swallowing in which the participant swallows liquid or food boluses of different consistencies prepared with barium contrast. The x-rays are recorded at 30 frames per second.
