Evaluating a new prosthesis control system for upper limb amputees

Assessment of Gesture Accuracy for a Multi-electrode EMG Sensor Array Based Prosthesis Control System

EARLY_PHASE1 · Phantom Neuro Inc. · NCT06446037

This study is testing a new control system for prosthetic hands to see if it can help people with upper limb amputations use their prosthetics more effectively by interpreting their muscle signals.

What this trial studies

This study assesses the performance of the Phantom X prosthesis control system, focusing on its ability to decode electromyography (EMG) signals for hand gesture control. The research involves both able-bodied individuals and those with upper limb amputations at the forearm level. Participants will wear a non-invasive multi-electrode array on their forearms to capture EMG signals, which will be analyzed to determine the accuracy of gesture control. The goal is to enhance the functionality of prosthetic devices for amputees.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 21 and older with transradial amputations who can follow study directions and provide informed consent.

Not a fit: Patients with higher-level amputations, significant muscle pathologies, or cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved control and functionality of prosthetic limbs for individuals with upper limb amputations.

How similar studies have performed: While the approach of using EMG signals for prosthetic control is established, the specific Phantom X system's performance is novel and has not been extensively tested in prior studies.
