Evaluation of a Multi-electrode Prosthesis Control System for Real-world Tasks Performance in Individuals With Upper Limb Transradial Amputation

Withdrawn before enrolling · Not applicable

Conditions studied: Upper Limb Amputation Below Elbow

In brief

This study tests how well the Phantom X prosthesis control system works. The system helps control a prosthetic hand using muscle signals from the arm. You'll wear a non-invasive version for one day in the clinic. You'll practice hand movements and then do two simple tasks with both your usual prosthesis and the Phantom X system. At the end, you'll fill out short surveys about your experience.
