| Outline of Final Research Achievements |
This study aimed to evaluate the effect of a wearable robot on the fall recovery motion and the risk of fall. Application of the perturbation, which mimicked the one occurring in the daily living environment, during walking caused the loss of balance or fall. Observation of such motions and motion simulation, which estimated the impact position and speed, enabled to identify the reaction strategy and injury risk.
Classification of the reaction strategy using factor analysis and comparison of motions using t-test suggested the separation of motion strategy owing to the timing of perturbation. Then, the extraction of the motion characteristics and understanding of the mechanism of the motion resulted in the estimation of the injuries. The relationship between the motion strategy and injury risk of the strategy helped to propose the countermeasure against such falls.
