Swallowing Rehabilitation Research Lab

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.
