ClinConnect Summary

This clinical trial is testing a new system called the Phantom X, which helps people control a prosthetic hand using signals from their arm muscles. The goal is to see how well this system works during everyday tasks. If you take part, you’ll visit the clinic for one day and wear a special, non-invasive device that reads your muscle signals. You’ll practice moving the prosthetic hand and then complete two simple tasks using both your current prosthesis and the Phantom X system. At the end, you’ll be asked to fill out short surveys to share your experience.

The study is open to adults aged 21 and older who have lost one or both arms below the elbow and are able to follow instructions and attend the study visit. People who have skin allergies to the device materials, have arm injuries, or other specific conditions may not be able to participate. This trial is not yet recruiting participants but is designed to help improve prosthetic hand control for people with arm amputations.
