The deglutition movement progresses though three phase of the mouth phase, the pharynx phase, and the esophageal phase are consecutive it. Especially, continuity from the mouth phase to the pharynx phase is important, and we also treat for every periods. We think that we can be done more efficient treatments if we can clarify the continuity of the shift from the mouth phase to the pharynx phase, so we did the purpose to clarify open large relation of the larynx that is an important element of the movement and the pharynx phase deglutition movement of the lower jaw that is a typical organ of the mouth phase deglutition. As a result, it was recognized that the positional change of lower jawbone could affect deglutition for the pharynx phase.
