| Outline of Final Research Achievements |
Expiratory muscle strength training (EMT) is effective for swallowing function, however its mechanism has not been fully elucidated yet. The purpose of this study was to investigate the morphological changes of the pharyngeal larynx under the use of endoscopy by performing EMT on patients with dysphagia who had a history of pneumonia. The subjects were divided into two groups with or without EMT (6 cases each) and intervened for 4 weeks. We compared pulmonary function, respiratory muscle strength, cough peak flow (CPF) and swallowing function which included by using endoscopy before and after intervention. The maximum expiratory pressure, FEV1 and CPF were significantly improved in the EMT-treated group, and the morphological change of the pharyngeal part also showed a large change in the horizontal and the vertical width when the EMT was performed. It is suggested that EMT can improve contraction force of the pharyngeal muscles and it may affect swallowing function.
