Outline of Final Research Achievements

In this study, we suggested a method to evaluate the swallowing exercise of human being using a figure of muscle sound for the purpose of maintenance, the recovery of the prevention and the swallowing function of dysphagia that might remarkably reduce QoL (Quality of Life) of people quantitatively, and to reconstitute titled "the quantitative evaluation of the swallowing function using the figure of muscle sound and the trial to a biofeedback". And we built the system which we did an effective line of the suprahyoid muscles as a biofeedback in the Shaker method as swallowing rehabilitation, and could show the shrinkage visually. It was in this way shown that the effective rehabilitation that we matched with an individual patient was enabled.
