Introduction 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.
Interpretation Decreasing foot stiffness can increase prosthesis range of motion, mid-stance energy storage and late-stance energy return, but the net contributions to forward
The lack of functional ankle musculature in lower limb amputees contributes to the reduced prosthetic ankle push-off, compensations at other joints and more energetically costly gait

Imagine a prosthetic foot that stores energy like a spring, adapts to uneven terrain like a mountain goat, and weighs less than your smartphone. That''s the magic of carbon
The technology, Controlled Energy Storage and Release (CESR), uses a microprocessor-controlled spring mechanism to capture and store elastic energy during heel strike.
Energy storing and return prosthetic (ESAR) feet have been available for decades. These prosthetic feet include carbon fiber components, or other spring-like material, that allow storing of mechanical energy during stance and releasing this energy during push-off .
The magnitude and the distribution of the energy stored and a series of stress and strain parameters were analysed for the test device using the proposed approach. The novel methodology proposed may act as an effective tool for the design, analysis and prescription of energy storage and return (ESAR) prosthetic feet.
Methods: Force-displacement data were collected at combinations of 15 sagittal and 5 coronal orientations and used to calculate stiffness and energy storage across prosthetic feet, stiffness categories, and heel wedge conditions. Results: Stiffness and energy storage were highly non-linear in both the sagittal and coronal planes.
Modern prosthetic feet have spring-like mechanics, deflecting and storing energy during mid-stance, and returning this energy during terminal stance. Researcher
Energy storing and return (ESAR) feet are generally preferred over solid ankle cushioned heel (SACH) feet by people with a lower limb amputation. While ESAR feet have been shown to have only limited effect on gait economy, other functional benefits should account for this preference.
