Joint Loads and Cartilage Stress in Intact Joints of Transtibial Amputees: Enhancing Quality of Life

Abstract

The goals of this project are to identify exercises that maintain intact limb knee and hip joint and cartilage tissue loads at safe levels and, consequently, enhance the quality of life (QoL) via prevention of intact limb joint arthritis for military transtibial amputees. Progress includes the following. 1) Completed experiments for all participants (10 control and 10 amputee) in gait, cycling, and elliptical training exercises. 2) Analyses of knee angles correct for soft tissue artifact and crosstalk errors in 4 control and 4 amputee participants. 3) Completed analyses for all participants of ground reaction, pedal reaction, and resultant hip and knee joint loads. 4) Continues EMG-driven Opensim inverse dynamic analyses of knee joint contact loads and finite element analyses of cartilage tissue loads. During year 3, results and findings have been presented as eight conference papers and 5 MS theses; preparation of 2 journal papers has commenced.
