Summary

Prostheses can be suspended from the amputated limb using a variety of techniques, such as straps and suction. Suspending the prosthesis by creating a vacuum between the prosthetic socket and limb using a pump has benefits over other techniques including improved limb health and mobility. A new pump design will be tested by prosthesis users in the laboratory to verify its functionality during walking.

Description

Human subject testing will involve a cross-sectional, repeated measures study consisting of a single 3 hour visit wherein participants will initially stand and then continuously walk at their self-selected speed for ten minutes on a level treadmill with the prototype under two randomly presented conditions of the mechanical system: 1) fully functional, and 2) locked to restrict axial displacement. After written informed consent is obtained, information on socket comfort and mobility capability will be collected. A load-cell will be installed proximal to the prototype and in-line with the prosthesis to measure instantaneous socket-reaction moments.

Medical and Biotech [MESH] Definitions

The part of a limb or tail following amputation that is proximal to the amputated section.

A ubiquitous target SNARE protein that interacts with SYNTAXIN and SYNAPTOBREVIN. It is a core component of the machinery for intracellular MEMBRANE FUSION. The sequence contains 2 SNARE domains, one is the prototype for the Qb-SNARES, and the other is the prototype for the Qc-SNARES.
