Outline of Final Research Achievements

The purpose of this study was to construct theory for choice of motor strategy under functional restriction based on optimization. At the first experiment, the relationship between the joint movement pattern and the energy cost (EC) during walking under a functional restriction of the hip flexion was examined. At the second experiment, we examined the relationship between jerk cost and the formation of the center of gravity trajectory during sit-to-stand motion with asymmetrical foot placement. At the third experiment, the relationship between stepping-over motion and floor reaction force under the restriction of knee flexion was examined. In conclusion, it was indicated that EC greatly contributed to the formation of joint movement pattern under functional restriction. On the other hand, it was shown that safety is given priority if they must avoid risk such as falls.
