Abstract
The study of human gait is of interest in determining its individual characteristics that affect the loads experienced by the joints of the lower extremities. To analyze the gait in the lateral projection, an experiment was carried out with placed markers on the subject's body to determine the interarticular angles in the hip, knee and ankle joints. The graphs of the dependences of these angles on time were built, corresponding to a certain phase of the step. It was found that the range of changes in the angle in the left ankle joint in the subject was significantly different from the dependence obtained for the right joint. Based on the subject's anamnesis, we associate these differences with the fact that there was an ankle joint injury that affected the condition of the ligamentous apparatus of the joint. In further work, it is proposed to consider a person's gait not only in the lateral, but also in the frontal (anteroposterior) plane to assess all movements in the joints, especially those associated with the abduction of the limbs and the human body from the vertical line on the specified plane.
