ABSTRACT:
A prosthetic foot includes an adapter element securable to a residual limb, a foot plate having a heel portion and a toe portion along the length thereof, at least one toe spring connected between the adapter element and the toe portion of the foot plate, and a heel spring connected between the adapter element and the heel portion. The heel spring may be a leaf spring or a tube type shock absorber. The concave side of the leaf spring exhibits a plurality of transverse ribs. Alternatively, a tubular pylon may have a collar mounted thereon for movement along the length of the pylon. A toe spring and a heel spring extend from the collar to form toe and heel portions of the prosthetic foot. A further heel spring is connected between the heel portion and another end of the pylon, and a non-extensible band extends between the heel portion and the collar. As another alternative, a tubular pylon has one end securable to a residual limb, and a collar is mounted to the pylon for movement along the length of the pylon. At least one toe spring is connected between the collar and the toe portion of a foot plate, while a heel spring is connected between the heel portion of the foot plate and another end of the pylon.
