Abstract

The goal of this study was to calculate muscle forces using different optimization techniques and investigate their effect on hip joint contact forces in gait and sit to stand. These contact forces were compared to measured hip contact forces [3]. The results showed that contact forces were overestimated, especially when muscle forces were calculated using computed muscle control. For static optimization, results were closest to measured contact forces. Also, differences between measured and calculated contact forces were dependent on the movement analyzed.
