DYNAMIC ANALYSIS OF THE HUMAN KNEE

The objective of this paper is to present a dynamic analysis of the human knee for various activities such as walking and stair ascending/descending. The results of this work is significant as it can used as inputs to joint simulators for artificial joint study, for rehabilitation purposes and to some extend applied to sports biomechanics. In the present work an experimental study consisting of a motion sensor and a force plate was used to capture the motion of subjects and to provide ground force reactions data that will serve as inputs to the model. Subjects in the 50-65 years old bracket performed activities such as walking, stairs ascending and descending. This age bracket was chosen because most of patients with knee-related problems are found in this age group. Some of the results from the present work correlated with that of published literature. However, the present analysis was based on a more comprehensive model of the knee, which makes the results more realistic to the actual mechanical behavior of the lower limb.
