Abstract. Non-articulated energy storage and return prosthetic feet lack any true articulation or obvious point of rotation. This makes it difficult to select a joint center about which to estimate their kinetics. Despite this absence of any clear point of rotation, methods for estimating the kinetic performance of this class of prosthetic feet ...

The general concept of energy storage and release of prosthetic feet is that they store energy during mid-stance and release the energy when it is desired, i.e. during push-off. These events are based on two major phases (Winter and Sienko, 1988) consistently seen in ankle power graphs in normal subjects.

Energy storage and return (ESR) feet have long been assumed to promote metabolically efficient amputee gait. However, despite being prescribed for approximately 30 yr, there is limited evidence that they achieve this desired function. Here, we report a meta-analysis of data from 10 studies that met …

In this model, the tibia was assumed to be rigid, and the soft tissues are assumed to be homogeneous, isotropic and linear elastic. Indentation of the tibia into the soft tissues at a time t, defined as δ(t), is calculated by [13]: (1) δ (t) = F (t) h π a 2 (λ + 2 G) where F(t) is the measured limb-socket force, and G and λ are the effective shear …
