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 .
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.
Do design matrices for energy-storing feet have clinical relevance?
A wide variety of design matrices for energy- storing feet was found, but the clinical relevance of its design parameters is uncommon. Definitive factors on technical and clinical characteristics were derived and included in the summary tables. To modify existing foot failure mechanisms, material selection and multiple experiments must be improved.
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.
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.
