Improving control of advanced robotic limb devices for stroke patients
Official title: Improving Myoelectric Prosthetic and Orthotic Limb Control Using Predictive Regression Algorithms and High-count Surface Electrodes
Run by University of Utah · NCT05509101 · Data updated 2026-11-12
This study is testing a new way to help stroke patients with limited movement use robotic limb devices more effectively by improving how these devices read muscle signals.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals who have had a first-ever ischemic or hemorrhagic stroke and have chronic hemiparesis.
✕Probably not a fit
Patients who are currently incarcerated will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to enhance the control of myoelectrically-controlled advanced powered orthoses, which are robotic devices that assist movement by interpreting muscle signals from the body. The approach involves using advanced predictive decode algorithms alongside a high count of surface electromyographic (sEMG) electrodes to improve the functionality of these devices. Participants will be individuals who have experienced a stroke and have chronic hemiparesis, allowing for targeted intervention to improve their mobility and independence.
Why it matters
Potential benefit: If successful, this study could significantly improve mobility and quality of life for patients with hemiparesis following a stroke.
How similar studies have gone: Other studies have shown promise in improving control of robotic devices using similar approaches, indicating potential for success in this area.
