Description
Summary:1 Introduction In their recent paper "Mechanical interaction of centre of pressure and force direction in the upright human", Gruben and Boehm (2012) present a model to show that the direction of the ground reaction force vectors in walking always pass closely through a single point, the Point of Intersection (Î ). See PDF]The conclusion is that, for any position of the CP and for any movement, the (resultant) ground reaction force vector runs through a fixed point PI, which is located a small distance vertically above the CM, see Fig. 1.
