Human lower limb dynamic analysis with applications to orthopedic implants

Abstract

In this paper we present the human lower limb inverse dynamic analysis in the sight of some useful dynamic parameters determination for orthopedic implants design. We elaborate the human lower limb mathematic model based on some cinematic and dynamic considerations obtained on experimental and analytical way. The inverse dynamic analysis has on its base the Newton-Euler formalism completed with Lagrange's multipliers method. Through this analysis we obtain the connection forces which appear at the human lower limb's joints level for walking activity. With these results we will study through finite element method an orthopedic implant which will partially replace the human lower limb's ankle joint. © Springer Science+Business Media B.V. 2010.
