Outline of Final Research Achievements

The purpose of this project is to make research the specificity of Parkinson disease (PD) under swallowing by measuring tongue pressure which generates when tongue comes in contact with hard palate.
Our results indicated that the magnitude of tongue pressure decreased in PD patients with or without dysphagia. Moreover the decreased tongue pressure made bad influence on oral and pharyngeal stage of swallowing. These results indicate the possibility that measuring tongue pressure becomes an new diagnosis tool for dysphagic PD patients and contributes on making clinical strategies for dysphagia.
