The investigators will utilize Videofluoroscopic Dysphagia Scale (VDS), that composed of fourteen categories, which can be divided into oral and pharyngeal phases to assess scores based on VFSS results. The oral phase composed of 7 items (lip closure, bolus formation, mastication, apraxia, tongue-to-palate contact, premature bolus loss, and oral transit time). The pharyngeal phase also included 7 items (triggering of pharyngeal swallowing, vallecular residues, pyriform sinus residues, laryngeal elevation, coating of pharyngeal wall, pharyngeal transit time, and aspiration). VDS can assess the components of dysphagia in such detail.
