COMPARISON OF KINEMATIC PARAMETERS OF GAIT IN TRANSFEMORAL AMPUTEES WITH BIONIC AND HYDRAULIC KNEE – CASE STUDY

Abstract

The development of new technologies has led to further improvements in prosthetic knee joints. The aim of this study was to compare kinematics in knee and hip joints during the gait of transfemoral amputees and to determine the effect of the type of knee joint used (bionic, hydraulic) on their symmetry. One female with transfemoral amputation participated in the study. Symmetry of lower limb movement in the hip joint is better for all monitored parameters for bionic knee joints. Flexion at heel contact and maximum flexion in the swing phase in the knee joint are more symmetrical at hydraulic knee joints; for all other parameters the bionic knee joints achieves better symmetry. Kinematics parameters in bionic knee amputees approximate to the parameters of gait in people without pathology
