What this Trial Is About
Sarcopenic dysphagia is defined as swallowing difficulty among the elderly due to the loss of whole body skeletal and swallowing muscle mass and function. However, the pathophysiology and dynamics of swallowing in sarcopenic dysphagia have been poorly investigated. Therefore, the present study aims to investigate the characteristics of sarcopenic dysphagia using the Videofluoroscopic study (VFSS) focusing on each phase of dysphagia, and surface Electromyography (surface EMG) to assess suprahyoid muscle activity. In sarcopenic dysphagia, impairments will occur in both the oral and pharyngeal phases, particularly affecting bolus formation, premature bolus spillage and laryngeal elevation during swallowing due to the loss of swallowing muscle mass and function. These changes will be considered to have led to an change of duration and amplitude of suprahyoid muscle activity measured via surface EMG.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- 65 years of age or older who underwent VFSS to evaluate the presence of dysphagia
- Diagnosed with sarcopenia based on the Asian Working Group for Sarcopenia (AWGS) 2019 cutoff values
- Cognitive ability to follow instructions for Videofluoroscopic swallowing study and surface electromyography
You will not qualify if you...
- History of cerebral hemorrhage or cerebral infarction
- History of neuromuscular diseases that could cause 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 cause dysphagia
- History of connective tissue disease
- History of cervical surgical procedure
- Cognitive impairment preventing following instructions for Videofluoroscopic swallowing study or surface electromyography
