Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin

Honors Projects

A 3D printed hand and arm prosthetic was created from the idea of adding bionic elements while keeping the cost low. It was designed based on existing models, desired functions, and materials available. A tilt sensor keeps the hand level, two motors move the wrist in two different directions, a limit switch signals the fingers to open and close, and another motor helps open and close the fingers. All sensors and motors were built on a circuit board, programmed using an Arduino, and powered by a battery. Other supporting materials include metal brackets, screws, guitar strings, elastic bands, small clamps, …

Predicting Walking Ability And Prosthetic Candidacy Following Lower Extremity Amputation: Systematic Review, Treatment Pathway And Algorithm, Scott Love

Student Dissertations

Purpose: The purpose of this study is a systematic review (SR) of existing literature to examine characteristics of persons with amputation which predict walking ability and prosthetic candidacy following lower extremity amputation (LEA). The identification, synthesis and summary of this evidence could assist in developing clinical practice guidelines, including a physical rehabilitation treatment pathway and a clinical algorithm. The importance of this project is the establishment to further develop evidence based LEA clinical practice guidelines. This evidence will assist the healthcare team in decision making, specifically considering evidence and patient-centric predictive characteristics.

Background: Currently, there is no multi-disciplinary physical …

The Use Of A Pylon Mounted Transducer For Investigating The Gait Of Transtibial Amputees, Justin Robert Brink

UNLV Theses, Dissertations, Professional Papers, and Capstones

Two areas of research interest in the design and use of lower limb prosthetic devices are how foot performance varies with design and how prosthesis alignment affects gait. The current study addressed both of these areas through the use of the JR3 triaxial transducer mounted at the base of the socket. The transducer is an innovative form of instrumentation that measures forces and moments at the end of the socket. Traditional measurement of gait uses a force plate buried in the floor of a gait laboratory. The study established that the transducer offers a viable means of instrumentation for amputee …
