Energy storage and release of prosthetic feet
This paper is the second part of a study on biomechanical and functional properties of prosthetic feet. The first part dealt with a biomechanical analysis related to user benefits. This part deals with subjective ratings and deciding factors for trans-tibia] amputees using 2 energy storing feet (ESF) and 2 conventional feet (CF). The Otto Bock Dynamic Pro and Hanger Quantum feet were used as ES...
متن کاملAnalysis of Rollover Shape and Energy Storage and Return in Cantilever Beam-type Prosthetic Feet
This paper presents an analysis of the rollover shape and energy storage and return in a prosthetic foot made from a compliant cantilevered beam. The rollover shape of a prosthetic foot is defined as the path of the center of pressure along the bottom of the foot during stance phase of gait, from heel strike to toe off. This path is rotated into the reference frame of the ankle-knee segment of ...
متن کاملTrajectory of the center of rotation in non-articulated energy storage and return prosthetic feet.
Non-articulated energy storage and return prosthetic feet lack any true articulation or obvious point of rotation. This makes it difficult to select a joint center about which to estimate their kinetics. Despite this absence of any clear point of rotation, methods for estimating the kinetic performance of this class of prosthetic feet typically assume that they possess a fixed center of rotatio...
متن کاملTranstibial amputee gait efficiency: Energy storage and return versus solid ankle cushioned heel prosthetic feet.
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. Here, we report a meta-analysis of data from 10 studies that met our selection criteria to determine whether amputee walking with ESR feet is more efficient than ...
متن کاملTranstibial energy-storage-and-return prosthetic devices: a review of energy concepts and a proposed nomenclature.
Prosthetic devices that can store and return energy during gait enhance the mobility and functionality of lower-limb amputees. The process of selecting and fitting such devices is complicated, partly because of confusing literature on the topic. Gait analysis methods for measuring energy characteristics are often incomplete, leading to inconsistencies in the energy classifications of different ...
