Swallowing Rehabilitation Research Lab

Coming Soon: Maximum pharyngeal constriction measurement tools are currently being updated to reflect the latest recommendations from the manuscript describing the ASPEKT method. A webinar recording describing the results is also available here. New measurement tools will be posted in the coming weeks. Release of these new tools will be announced on our twitter and facebook pages. Stay tuned!

Normalized Maximum Pharyngeal Constriction (nMPC)

Professor Steele’s research in our lab suggests that measurement of pharyngeal constriction on a single frame relative to a reference scalar (square length from the anterior inferior corner of the C4 vertebra to the anterior inferior corner of the C2 vertebra), is adequate for capturing variations pharyngeal constriction during swallowing across different conditions.
