Surface Electromyographic Analysis of Normal Swallowing in Children: An Exploratory Study

This exploratory clinical trial aims to investigate the mechanism of sequential muscle contractions during normal swallowing processes, including spoon, straw, and cup feeding, in children aged 2 to under 10 years without swallowing disorders. Surface electromyography (sEMG) will be used to evaluate activation patterns of the orbicularis oris, submental, and hyoid muscles during liquid, semi-solid, and solid intake. The study seeks to characterize the timing, duration, amplitude, and coordination of swallowing-related muscle activity in typically developing children. Findings from this study are expected to provide foundational physiological data to inform the development of pediatric-specific neuromuscular electrical stimulation (NMES) protocols for dysphagia treatment.
