RECRUITING

Improving Prosthetic Arms for Amputee: A Better Fit and More Functionality

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This research and development will improve upon and investigate the potential validity of an innovative new transradial socket and harness design (the KSH system) that offers an alternative to standard hard sockets and rubber liners with a hybrid polymer and textile-based design derived from advanced athletic shoe technology. The project consists of designing, custom fitting and evaluating the function and comfort of the this new novel system. The study will take place in 3 phases; Phase 1, five experienced Veterans with transradial arm amputations will be recruited to provide guidance and to assist with the design and development. Experienced end-user Veterans and Clinical staff will work together to assist with design, develop the fitting process and working with engineers on the design of a completely digital fitting device for measuring the residual limb and locating bony prominences of the limb to inform the socket design. Phase 2, testing and assessment, the design and process validation will take place with the five Veteran upper transradial arm amputees Phase 3, an additional 20 Veterans with transradial arm amputations will be recruited and fit with the KSH system and undergo a series of evaluative tests. Veterans will perform a series of static and dynamic tasks to evaluate function, comfort and load bearing failure. The primary goal of this study is to improve upon the current preliminary prototype and to test it with a broader population of potential users to help advance the engineering and design, and to learn the potential to fit a range of Veterans with transradial amputations.
