Research Abstract

The aim of this study was to measurement movement of hyoid and epiglottis at swallowing. In this study, It was revealed that three-dimensional position detection was possible in the living body of laboratory animals (rabbit) using some capture wireless magnetic markers in the magnetic motion capture system and date sampling of the movement of hyoid and epiglottis at swallowing was performed.
