Testing a Wearable 3D-Printed Prosthetic Arm

Summary

We are doing a study to test a lightweight, 3D-printed prosthetic hand. The goal is to understand how easy, comfortable, and natural the prosthetic hand feels to use during everyday tasks. Participants will wear the prosthetic hand and perform simple movements such as opening and closing the hand, holding objects, and completing basic tasks, such as pulling a zipper or opening a door. Small sensors placed on the skin will measure muscle signals from the arm (called electromyography, or EMG). These signals are used to help the prosthetic hand move in response to the participant’s intended motion. After completing the tasks, participants will be asked to share their feedback about comfort, ease of use, and how well the prosthetic responded to their movements. This information will help improve future prosthetic designs so they feel more natural and easier to control.
