Normal Pediatric Swallowing PhysiologySwallowing Muscle Activation Patterns in ChildrenSwallowing Function

Study summary

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.

Inclusion Criteria: * Children aged 2 to under 10 years * Children without a diagnosis of dysphagia * Children without congenital brain lesions or respiratory conditions (e.g., bronchopulmonary dysplasia \[BPD\], respiratory distress syndrome \[RDS\]) that may affect the swallowing process * Children whose legal guardians provide informed consent for participation * Participants who meet all of the above inclusion criteria Exclusion Criteria: * Refusal to provide consent for participation in the study * Refusal to undergo the study procedures or assessments * Determined by the principal investigator to be unsuitable for participation -Meeting any of the above exclusion criteria -

Primary outcome measure(s)

  • Electromyography-based activation patterns of swallowing-related muscles (orbicularis oris, submental, and hyoid muscles) — Single assessment at baseline visit
    Surface electromyography (EMG) parameters measured during swallowing tasks, including Onset latency (time of muscle contraction onset), Offset latency (time of muscle contraction termination), Duration (duration of muscle contraction), Peak amplitude (maximum amplitude), and Area under the curve (AUC) of the electromyographic signal
