Outline of Final Research Achievements

We analyzed 1)sitting position (the posture that a sole sets up), 2) sitting position (the posture that a sole does not ground), 3) standing position. We have analyzed genioglossus muscles, pretibial muscles, rectus abdominis muscle , erector muscle of spine , sternocleidomastoideus muscle. We have also analyzed the breathing phase and the deglutition phase by pneumogram from nasal mask during swallowing . We have used three types of food (beef jerky, jelly, water)to test swallowing function. As a result, with the side locus that a sole did not ground, muscle activity of the pretibial group of muscles weakened, and rectus abdominis muscle group, erector muscle of spine group, activity of the musculus sternocleidomastoideus group increased for the maintenance of the trunk adversely. Furthermore, what effect gave you in a timing of breathing cooperation swallowing from the sternocleidomastoid excessive tension that was accessory respiratory muscles was found.
