| Research Abstract |
We analyzed head and mandibular movements with intake of different-sized food pieces during realistic eating. Head, body and mandibular movements of20 healthy young adults eating the apple pieces were simultaneously recorded in three dimensions by a wireless opto-electronic system. And linear motion, and the inclination angle of the head and upper body, and mouth opening range were compared during intake of different-sized apple pieces. Mouth opening, head-neck rotation angle and the amount of upperbody forward translation and inclination increased with larger apple pieces. However, isolated relative head motion was stabilized. We conclude that upper body forward motion and head-neck rotation assist mouth opening while stabilizing head orientation, and that the range of head-neck rotation angle, upper body translation and range of mouth opening change with food size during realistic eating.
