6 FAQs about [Carbon fiber energy storage feet]

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 .

How is energy stored in a carbon fiber forefoot?

Additional energy is stored during the deflection of the carbon fiber forefoot (Collins and Kuo 2010; Zelik et al. 2011; Segal et al. 2012; Zelik 2012). The timing of the energy release is controlled with the ability to augment the powered plantar flexion phase of terminal stance.

What is a controlled energy storing and returning foot?

The so-called Controlled Energy Storing and Returning Foot (CESR Foot) was developed to enhance the push-off properties of passive prostheses. CESR feet do not store energy during posture, but use the weight of the body to accumulate energy during initial contact and release energy when needed .

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