Finite Element Analysis (FEA), the widely accepted virtual testing process, involves creation of a virtual geometry model that is converted into a Finite Element Model (FEM) and complemented by material and load models. The creation of geometry model is presently supported by various NURB packages while the material model can be translated from CT scan via techniques of power law or micro-mechanics. The load model remains at discretion of the researcher and his resources. This leads to a situation when the load model is limited to simulate over simplified daily life activity (DLA) such as standing position and any other activity where the forces can be computed from static equations without consideration of the muscular activity. This creates a drawback for correct simulation of the test ‘in silico’ that should be carried under the maximum load condition thus considering inertial forces and additional muscular load. This paper will provide brief overview of the present way to evaluate the load for required DLA and the final results obtained when modelling an ordinary walk. The results (Sant et al., 2012), based on validated model (Arjmand et al., 2006), will be compared with results of AnyBody load model applied to the lumbar spine.
