| Outline of Final Research Achievements |
For the monitoring of chew and swallowing condition in long period, the silk electrode has been used on the neck surface. Because of artifacts by the phonation and respiration movements, it was difficult to achieve a steady monitoring for the swallowing. The structure of the larynx and pharynx focusing those movement was evaluated histologically to assume the reason of the artifacts, and novel findings of distribution of elastic fibers and enteric plexus are published. To increase the stability of monitoring, the soft, paper type electrode which can detect surface movements of the skin by changing its electronic resistance has been developed and the experiment of monitoring in healthy subject is starting. Also the swallowing functions of head and neck cancer patients (the study will be carried out in those cases) has been evaluate and published.
