Rehabilitation Practice and Science

Objective: Post-stroke dysphagia is associated with increased morbidity and mortality in acute stroke patients due to malnutrition or aspiration. This study compares the hyolaryngeal movement during swallowing between post-stroke dysphagia patients with and without penetration/aspiration by videofluoroscopy swallowing study (VFSS). The goal was to find out possible defects in swallow mechunism for improving post-stroke dysphagia swallowing training. Method: We retrospectively collected VFSS images from stroke in-patients in a medical center in Central Taiwan from October 2015 to April 2017. The subjects were subdivided according to the VFSS results and 8-point penetration-aspiration scale (PAS) into those with penetration/aspiration (PAS ≥ 3) …
