The purpose of this study was to analyze trouble of tongue movement in patient with dysphagia. * digital videofluorography (VF) in order to investigate the role of tongue for mastication and swallo* VF that equipped in our hospital had become a useful tool because of series of our modifications of allowed a relaxed posture for the patient and easy orientation of the patient's head under the cond* level X-ray exposure.
