Analysis and Evaluation of Walking Characteristics with Various Levels of Weight Bearing by Using Wearable Motion Measurement Device

Currently, manned space exploration is actively being promoted internationally, so it is necessary to clarify kinematic changes of locomotion under microgravity. In this research, walking in a microgravity environment was simulated by using an anti-gravity treadmill and its walking motion was measured with a wearable motion measurement device. As a result, it was found that it becomes floating and slower tiptoe walk as the weight rate is small from ground reaction forces and joint angles, and the walking behavior characteristics of a lower body greatly changes between the weight rate of 40% and 60% from the joint angles.
