Abstract
Partial Weight Bearing Gait (PWBG) is commonly used method for gait rehabilitation after hip or knee joint surgery. Partial Weight Bearing Gearis emerging gait rehabilitation device for PWBG. By compensating vertical force in gait, apatient can exercise gait with less effort and do exercise of low limb muscle not for maintaining gait ability. However, quantitative research how much weight should be compensated, how much joint force, moment and muscle force weight bearingaffects, about change of trajectory change according to weight bearing are not sufficiently especially mobile PWBG on overgound not on treadmill. Even though there are quantitative research for PWBG, most of them studied on the treadmill. In this paper, trajectory changes of center of mass, knee and ankle joint, joint force (hip, knee, ankle), joint moment (hip, knee, ankle), ground reaction force using VICON and muscle force (rectus femoris, tibia anterior, gastrocnemius, biceps femoris) using OpenSimas degree of weight bearing changes are presented in wheel type PWBG and suggest various guide line of weight bearing depending on patient situation. ⓒ 2017 DGIST
