Spatio-temporal Characteristics of Human Gaits based on Joint Angle Analysis
In order to study the spatio-temporal characteristics of human lower limbs at different walking speeds, VICON MX three-dimensional morion capturing system was adopted to measure the three dimensional motion trajectories of lower limbs when human were walking on the treadmill. Through Matlab and Origin Pro7.5, the joint angles of lower limbs were calculated and gait cycles were divided. The results of joint angle analysis showed that in single motion cycle hip joint moved gently while knee joint and ankle joint moved choppily. With gait speeds increasing, support phase decreased and swing phase increased; the motion ranges of hip joint angles and knee joint angles changed slightly, increasing from 22.00° to 30.81° and 55.37° to 64.13° respectively, the motion range of ankle joint increased significantly from 22.09° to 59.66°; gait speed increasing made no significant impact on motion model of lower limbs. This paper will offer realistic theoretical evidences for bionic machinery design by studying the motion laws and gait characteristics of human.
