THE SYMMETRY IN GAIT KINEMATICS OF ADOLESCENTS’ CASE STUDIES

Abstract

A gait cycle of 20 adolescents has been analyzed, representing each of them an age-gender group within a period of five years. The basic step values, the flexion-extension angle values between trunk and thighs (hips), thighs and calves (knees), calves and feet (ankles), and the angle between the horizontal and thighs were calculated. The symmetric movements of the lower limbs of each individual can be observed by means of angle-angle diagrams and the statistical results indicate the significant differences between right and left joints. After the analysis it is possible to infer that the symmetry in walking is developed during the latest years of the adolescence, but there are significant differences between right and left angular displacements.
