A Study of the Centrodes of Human Knee Joints Using Differential Method and Rigid-body Displacement Matrix Method

摘要：

The kinematics characteristics of the human knee joint can be represented by its centrodes. This paper provides an alternative method to construct the centrodes by using commercial digital camera to take the sequential pictures. In order to eliminate the undesired movements, a testing chair and a brace are specially designed. Two methods are introduced to constructe the moving centrodes of knee joint from the measured data. The rigid-body displacemnt matrix method provides a quick way to construc the centrodes. The differential method provides a much smooth curve to construt the centrodes. This paper provides a non-expensive, non-invasion, and non-radiation way to study the centrodes of human knee joint.
