Diseño de molde para muñón de pierna con altura ajustable de bajo costo, para prótesis de rodilla con energía cinética

Objective Design a leg stump mold and base and manufacture it, with variable center of gravity adjustment, the cost should not exceed 50% of the prostheses that exist in the market, for this it will be made with accessible materials that are easy to acquire and low cost. Methodology Take a mold of the stump of the subject in plaster, then make the male the same in plaster, to continue the mold in fiberglass and resin, with a metal support at the bottom, where it will be attached to a machined aluminum base.
