presented by Catriona Steele
In this course, Catriona Steele discusses strategies for evaluating the swallowing safety and efficiency of patients via video fluoroscopy. The course reviews the relevance of measurable residue levels and visible aspiration events to swallowing impairment and gives participants an overview of the Normalized Residue Ratio Scale (NRRS) and the Aspiration-Penetration Scale (APS). Participants will learn to distinguish between normal and abnormal swallowing function, and will have the opportunity to apply their knowledge to a series of case-based scenarios.
Dr. Catriona M. Steele is the Director of the Swallowing Rehabilitation Research Laboratory at the Toronto Rehabilitation Institute. She also teaches in the Graduate Department of Speech-Language Pathology at the University of Toronto. Prior to completing her Ph.D., Dr. Steele worked as a medical speech-language pathologist for 10 years. Dr. Steele is known for her commitment to pursuing theoretically driven research that will underpin clinical interventions with sound empirical evidence. She has received particular recognition for her work on tongue function in swallowing. Dr. Steele holds research funding from the National Institutes of Health in the United States, a Canadian Institutes of Health Research New Investigator Award, and funding from the Heart and Stroke Foundation of Ontario. She has published more than 80 peer-reviewed publications. Dr. Steele is in demand as a teacher around the world, and has given workshops and invited lectures across North America, Europe, Japan, China, Korea, Chile, New Zealand and Australia.
Dr. Steele introduces swallowing safety, specifically regarding penetration-aspiration, as a major functional goal for patients, and describes the Penetration-Aspiration Scale and delineation of normal vs. abnormal function. Participants will receive practice in rating swallowing safety.
This chapter focuses on rating swallowing efficiency by objectively observing reside after swallowing in patients experiencing dysphagia. Among topics discussed are rating residue, decision-making regarding frame selection and delineation of normal vs. abnormal function. Participants are also given the opportunity to practice in rating residue using the ordinal rating scales and NRRS.
