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.
