Instrumental kinematic analysis of the condition of the hip, knee and ankle joints in normal and at hypermobility syndrome joints in cycle step

We used the kinematic instrumental method to analyze the functional state of the hip, knee and ankle joint in girls of 12-15 years old in norm and under the hypermobility syndrome with recurrent subluxation of the left patella. A significant increase in the angle of external rotation of the knee joint in the support phase was revealed; we also demonstraded the decrease in the angles of flexion, extension, and increase in the angle of rotation and the appearance of internal rotation of the hip joint on the left in the support phase. Changes in function in all joints studied in the transfer phase were noted. The results of the research will form the basis for the table of norms of the kinematic analysis of the step-cycle of a person of different age groups.
