The swallow function is a multidirectional process that depends on complex neuro-muscular network. The function can be evaluated using instrumental, such as fibreoptic endoscopic evaluation of swallowing (FEES), videofluoroscopy, or well structured scales. There are many questionnaire and scales for assessment of swallow but very few have been validated. The study will assess the construct validity and reliability of the Turkish version of Pharyngeal Residue Severity Rating Scale as known as Yale Pharyngeal Residue Severity Rating Scale.
Purpose of the study is the validity and reliability of the Turkish version of the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS-T), so that it would be used as an assessment tool for dysphagia patients.
