Dynamic Stability Analysis of Random Multi-Obstacle Crossing in Elderly

Abstract

To improve the accuracy of dynamic stability analysis of gait across obstacles. The conventional kinematics parameters and temporal dynamic parameters were calculated and compared. The dynamic stability control ability of the young group, the old group, and the fall group was analyzed when crossing obstacles of random height. The kinematic parameters can express the difference in dynamic stability caused by aging, and the temporal dynamic stability parameters can express the subtle differences between the fall group and the elderly group, and the two-dimensional ROSa Shannon entropy is more sensitive. This paper analyzes the performance of different parameters in analyzing the difference in dynamic stability when crossing obstacles of random height, which improves the accuracy of the dynamic stability analysis method for crossing obstacles
