Linking swallowing problems to suprahyoid muscle activity in sarcopenic dysphagia

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational study enrolling people aged 65 and older diagnosed with sarcopenia who undergo videofluoroscopic swallowing study (VFSS) and surface electromyography (sEMG) of the suprahyoid muscles. Investigators will record VFSS to characterize oral and pharyngeal phase swallowing dynamics and use sEMG to measure suprahyoid muscle amplitude and duration during swallowing tasks. Participants with major neurologic, structural, or cognitive causes of dysphagia are excluded to focus on sarcopenic mechanisms. The study will analyze relationships between sEMG signal patterns and specific VFSS abnormalities such as bolus formation, premature spillage, and laryngeal elevation.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* 65 years of age or older who underwent VFSS to evaluate the presence of dysphagia
* Patient who diagnosed with sarcopenia based on the cutoff values of the Asian Working Group for Sarcopenia (AWGS) 2019
* Cognitive ability to follow instructions for Videofluoroscopic swallowing study, surface electromyography.

Exclusion Criteria:

* History of cerebral hemorrhage or cerebral infarction
* History of neuromuscular diseases that could lead to dysphagia such as Parkinson's disease, amyotrophic lateral sclerosis, Guillain-Barre disease
* History of Tracheostomy
* History of oropharyngeal cancer
* History of esophageal structural disease that could lead to dysphagia
* History of connective tissue disease
* History of cervical surgical procedure
* Cognitive impairment who cannot follow instructions for Videofluoroscopic swallowing study, surface electromyography
