The effects of sarcopenic dysphagia on the dynamics of swallowing organs observed on videofluoroscopic swallowing studies.

The decline in swallowing function of sarcopenia patients was characterised by lower laryngeal movement and enlargement of the pharyngeal cavity due to decreased skeletal muscle mass and decreased muscle strength. The present study suggested the usefulness of measuring ALUM during swallowing and measuring the pharyngeal area with VFSS as indicators of decreased swallowing muscle function in sarcopenia.
