Energy storage and return in dynamic elastic response prosthetic feet

Abstract

Dynamic Elastic Response prosthetic feet are designed to store energy in midstance and return a portion of that energy to assist the amputee with push-off. While dozens of designs exist, the literature has not developed a consensus understanding of foot function. Several methods are explored to determine prosthesis energy storage and return, including joint translational power, segmental power, and prosthesis instrumentation.
