Subject specific modelling for a better understanding of the locomotor disorders

Units : Laboratory of Anatomy, Biomechanics and Organogenesis | ULB190

Description :

Physically based prediction of joint and muscle force distribution using multibody mechanics and numerical methods of mixed
dynamics requests accurate adjustment of the model parameters defined in reproducible coordinate system (CS) using strict definition of
anatomical landmarks (ALs). This research focuses on development of customizable dynamical model of human passive motions, based
on accurate 3D bones and soft tissue reconstruction, medical imaging data (CT, MRI) and stereophotogrammetry by digital cameras
during subject dissection. Customizable dynamical models were imported as bone surfaces and soft tissue attachment data of one
subject's right leg in MSC ADAMS software. Currently the model includes hip joint, femoro-tibial joint, femoro-patellar joint and ankle
joint. Joints are simulated by full impact contacts and constrained by corresponding ligaments. Passive motion simulation were
obtained by constraining the model with cylindrical and hinge joints connected to iliac and metatarsus respectively. Impact contact
between calcaneus and floor was also implemented.
