Gait – pathology or phisiology

The purpose of our scientific work was to study some mechanisms of formation of human gait, to study some electromyographyc (EMG) and biomechanical features of gait in pathological conditions and volunteers. The gait of a person is a peculiar kind of two-legged movement, in which the support for one leg cyclically changes the biaxial period, and then the support to the other leg. Gait is figuratively described as “controlled fall”. At each new step, the person bend over and begins to fall, which is hampered by the advanced leg. After it touches the earth, the weight of the body is transferred to it, the knee bends, and erects, returning the body to its original position. That is why many authors represent gait as model of the “inverted pendulum” (Figure 1).
