RECONSTRUCTING THE OSCILLATIONS OF THE CENTER OF MASS OF THE HUMAN BODY IN UPRIGHT STANDING
P. G. Morasso, G. Spada, R. Capra
Abstract:
The stability of upright posture is usually analyzed by means of force platform measurements. The outcome is the trajectory of the Center of Pressure (COP) of the ground reaction. This point is not coincident with the projection of the Center of Mass (COM) on the support surface and the evolution of the COM-COP difference is a physiologically significant variable. In the paper an algorithm is described for recovering the COM from the COP: it is based on a dynamic model (the postural inverted pendulum) and the integration of the corresponding ordinary differential equation by means of a variational approach based on spline functions.
