| Research Abstract |
The research project 1) developed a system for automatic calculation of TP values which were expected as potent parameters for evaluation of muscle activity patterns, 2) validated the TP values theoretically in simulated data, 3) confirmed the usefulness of the TP values in food discrimination by analysis of the parameter recorded in the swallowing-related muscles, 4) confirmed the usefulness of the TP values as well as other conventional parameters in food discrimination by analysis of masseter (jaw-closer) activity, and 5) examined a parameter for suprahyoid (jaw-opener) activity in food discrimination by calculation of a ratio in each chewing cycle.
