Abstract:
In this study, biomechanical parameters of lower
limb joints due to motion changes have been estimated to
develop the 3-D model that can analyze dynamic gait simulation
for wearable walking assistant robot. Motion data which
include stair up and sit-to-stand condition of human motion
upon normal person with no nervous system and
musculoskeletal disease was obtained from 3-D motion analysis
system. As a result, it was observed that maximum torque value
of hip joint (1.26Nm/kg) was much higher than knee joint
(0.49Nm/kg) during stair up stage in sagittal plane. On the other
hand, maximum torque value of knee joint (0.72Nm/kg) was
higher than hip joint (0.18Nm/kg) during sit-to-stand stage
using walker. And maximum torque value of knee joint
(1.20Nm/kg) was higher than hip joint (0.87Nm/kg) during
sit-to-stand stage with no constraints. In this study,
biomechanical characteristics of lower limb joint upon various
conditions were presented and these data can be applied to
biomedical research field that include wearable walking
assistant robot.
