| Outline of Final Research Achievements |
We analyzed tongue pressure (TP) production during squeezing jelly samples with nine kinds texture properties in healthy subjects. Maximal magnitude of TP in early and middle stages was higher for jellies with larger fracture strength and lower for that with larger fracture strain, suggesting that the strength of tongue-palate contact was modulated widely according to the initial fracture properties. Also we analyzed the the relationship between TP, bolus transport and hyoid excursion, and found the temporo-spacial coordination between TP and hyoid excursion.
