Introduction
Gait analysis is a tool to study locomotion and has been employed in sports, rehabilitation, and health diagnostics.
In running, we can define different phases of locomotion within a gait cycle; swing and stance.The swing phase is when the limb leaves the ground, and is repositioned to come into contact with the ground. The stance phase is begins with the foot making initial contact with the ground until the distal aspect of the foot pushed off.
Kinetics and kinematics are two ways to characterize gait. Kinematics is the branch of biomechanics concerned with the motion of objects without reference to the forces that cause the motion; Kinetics is the branch of biomechanics concerned with measuring and studying the rates of reactions (i.e., ground reaction forces). For example, in some types of sports training, the method is applied to recognize the faults in athlete performances so that they can improve. In the field of biomedical engineering, gait analysis has been a fundamental method and assistive tool to characterize human locomotion. Gait analysis has attracted the interest of researchers and clinicians (Weijun, Tao, Liu, Zheng and Feng, 2012).
