Kinematics and Kinetics of Healthyand Osteoarthric Knee During Walking Stairs

Abstract

This paper presents the results obtained for healthy subjects and osteoarthritic patients during climbing and descending stairs. The variations and the maximum flexion-extension angles and the maximum reaction force values are presented. The climbing and descending tests demonstrated that the maximum values of flexion-extension angle are smaller for osteoarthritic knees than for healthy knees. The angle values are higher on descending than on climbing for all participants. For climbing stairs, the values are (1.25-1.4) body weight and for descending stairs, the values are (1.4-1.6) body weight.
