Respiratory Capacity and Swallowing Function in Spinal Disorders: A Pilot Study

2019-10-09 09:21:34 | BioPortfolio


This study is part of a larger grant, for which the overall goal is to collect measurements of liquid flow through the oropharynx (i.e., mouth and throat) during swallowing.The focus of this study is to evaluate the flow of liquids of varying consistency in the spinal disorder population.


Thickened liquids are commonly used as an intervention for dysphagia (swallowing impairment). However, the field lacks a clear understanding of how liquids of different consistencies behave during swallowing. In order to improve understanding of the effectiveness of altered liquid consistency for improving dysphagia, the investigators are studying liquid flow through the oropharynx. This study explores this question in individuals with spinal cord injury. Participants will swallow 20% w/v barium thickened to different consistencies (thin, slightly thick, mildly thick, moderately thick and extremely thick) using commercially available food thickeners. Swallowing will be observed under videofluoroscopy. Simultaneous measures of airflow via nasal cannula will be used to study respiratory-swallow coordination in this study sample.
