Abstract

Joint stiffness is a major manifestation of joint disease. Nevertheless, an extensive review of the literature reveals that little has been done to characterize joint stiffness quantitatively or qualitatively. A method is described whereby joint stiffness can be measured in precise physical terms. The major components of joint stiffness in normal and arthritic subjects are elasticity and plasticity. Viscous stiffness is small, and friction is negligible even in badly damaged joints.

In a recent article [1], Pun and Semercigil successfully applied a joint variable stiffness control (VSC) scheme to a one-link flexible arm. A standard finite element method was used to discretize the continuous system and produce global matrices. The Newmark-b method was applied to integrate the gl
