Using the anterior numerical data, as well as the analytical relations (Kwak et al., 2000; Nor<strong>din</strong>, 2005), there were determined using the Matlab programme, the chart of the variation of the components of the reaction force from the elbow articulation, Rcx and Rcy and the moment of reaction from the elbow articulation, in flexure move for 1 s, represented in Figs. 1 and 2. The method of reducing the forces to a given point is useful in the converse dynamic analysis, given the fact that the muscular forces, tendons forces, ligament forces and the forces from the bony surfaces in
