Abstract
Accurate reconstruction of bone motion using marker tracking is still an open issue in biomechanics. In this paper a novel approach for gait motion reconstruction is presented that is based on the analysis of kinematical loops and the reconstruction of functional skeleton features from segmented MRI data. The method uses an alternative path for concatenating relative motion, starting at the feet and closing at the hip joints. The discrepancies between predicted and geometrically identified functional data, such as knee axis and hip joint centers, gives rise to a cost function, which is the basis for model addaptation. Computations are performed with the object-oriented library MOBILE.
