Abstract
A prosthesis foot (1) comprises a light-weight hollow core (3) which by a combination of shape, material and material thickness forms a system of elastic and rigid areas, so that the core in itself forms a joint system, which can be connected directly to a foot adapter (2) without the mediation of separate elastic or articulated elements. The core or skeleton (3) preferably consists of a plastics material having good resistance to folding ("hinge material"), and it is preferably made by blow molding, injection molding, rotation molding, or the like. The new prosthesis foot has low weight, is easy and inexpensive to manufacture and provides for very good simulation of the possibilities of movement and the pattern of movement of the biological foot during walking.
