Comparison of Myoelectric and Bionic Hands in Adults With Upper Limb Amputation Assessing Hand Function, Body Image, and User Satisfaction

What this Trial Is About

This research aims to compare myoelectric and bionic prosthetic hands to understand differences in upper limb function, body image, and user satisfaction among individuals with upper limb amputations. It focuses on answering whether the functional abilities differ between these two types of prosthetic devices used by people with amputations. The study is observational and involves adults aged 18 to 65 who regularly use prosthetic hands. Participants will either use advanced bionic prosthetic hands featuring multi-articulating structures and enhanced control systems designed to improve function and dexterity or myoelectric prosthetic hands controlled by muscle signals from the residual limb that provide basic powered hand movements. These groups allow comparison of the newer bionic technology against conventional myoelectric devices. During the study, participants will complete assessments including the Upper Limb Functional Index-15, Amputee Body Image Scale, and Orthotics and Prosthetics Users Survey at baseline. These measures will help evaluate hand function, body image perception, and satisfaction with prosthetic use. The study is led by Gulhane School of Medicine and participation spans from November 2025 to March 2026, involving adults with unilateral upper limb amputation who have been using prostheses for at least six months.
