What the trial is, and whether it could suit you

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 sur

📋 Eligibility rules (as published)
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.
