Energy storage foot training issues

What are energy storing and return prosthetic feet?

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 .

Do energy storage and return feet affect the propulsion of the body?

The effect that energy storage and return feet have on the propulsion of the body: a pilot study. Proc IMechE, Part H: J Engineering in Medicine 2014; 228 (9): 908–915. 78. Hawkins J, Noroozi S, Dupac M, et al. Development of a wearable sensor system for dynamically mapping the behavior of an energy storing and returning prosthetic foot.

Are energy storing and return (ESAR) feet a good choice?

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.

Are energy storage and return feet safe for amputees?

The strain and stress seen in the three tests were within safe limits, while most of the energy was absorbed in the ankle component of the prosthesis. Energy storage and return (ESR) feet have long been assumed to promote metabolically efficient amputee gait.

Are energy storage and return (ESAR) prosthetic feet effective?

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.

Do energy storage and return feet promote metabolically efficient amputee gait?

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.
