The virtual testing in silico is widely accepted technique and will be used in our work to simulate a walk. The already existing Finite Element (FE) model of the lumbar spine was reused while the virtual behaviour was controlled by a set of constrains and a load data, normally transferred through the load-bearing tissue. The magnitude and character of the used load depended on the physical activity, external loads, physical condition of the subject and its specific factors such as gender, health condition, etc. Most of the published simulations used estimated simplified loads that barely simulate the real behaviour. This paper will discuss performance of the lumbar segment during the walk. The musculo-skeletal system is a statically indeterminate system thus the forces were solved via computational modelling using the trajectories recorded by VICON system, and consequently exported into an open software for computation. All forces acting on the segment were exported to into Finite Element (FE) database and the obtained results presented the importance of correct material model as well as the corresponding load model.
