In this work, free and treadmillwalking kinematics of human locomotion is studied and compared.All measurements are performed on one female subject.The lack of equqipment (only one camcoder, treadmill and one PC) was replaced with multiple measurements and statistical data processing using the Bootstrap method.The trajectories for the hip, knee and ankle agles for free and treadmill walking are shown graphically.Theangles for left and right leg are compared.The angle-angle diagrams for hip-knee angles are shown graphically.
