About Feet | Ottobock US Shop

Energy storage. A foot made with carbon fiber for energy storage literally gives you a spring in your step. The carbon fiber acts as a spring, compressing as you apply weight and propelling you forward as your foot rolls, returning energy to your step as the spring releases. Some prostheses have one spring in the heel and a second spring in the

6 FAQs about [Energy storage universal foot]

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 .

Is a safe foot the original energy storing foot?

Although not a brand new design, the SAFE foot (Stationary Ankle Flexible Endoskeleton) has recently been advertised as "the original energy storing foot." In our view, this may be stretching the point, since we believe the flexible keel serves primarily to dissipate energy as it accommodates to irregular surfaces.

What is energy storage and return prosthetics?

Preliminary energy storage and return prostheses incorporated an elastically deflectable keel in the prosthetic foot aspect. This design would store a portion of energy during the impact of stance initiation with a subsequent release during the terminal aspect of stance.

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

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.

Does a Proflex foot store more energy during stance or push-off?

The Pro-Flex foot stored more energy during stance than the Vari-Flex foot (p = 0.022), returned more energy (p = 0.045), more of that energy was delivered during push-off (p = 0.023), and these results occurred with large effect sizes and observed power (Table 1 ).
