Outline of Final Research Achievements

We analyzed the feeding movements of oral cavity using a motion capture, when subjects chewed food with various kinds of posture and when a meal was provided from various kinds of directions during assisted feeding. It was suggested that the posture of the body affects the chewing motion, and that the head posture and then the food-intake movement of mouth come under an influence of the direction of feeding assistance. We note that attention on food-intake and mastication is required during management of posture and an assistance method during feeding.
