Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In order to study the spatio-temporal characteristics of human lower limbs at different walking speeds, VICON MX three-dimensional motion 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.
