What this trial studies

This study investigates the effectiveness of non-invasive electrical spinal cord stimulation combined with activity-based rehabilitation to enhance hand and arm function in patients who have experienced a chronic ischemic stroke. The researchers aim to activate spinal networks that have lost control due to the stroke, potentially leading to improved voluntary movement in paralyzed muscles. Participants will undergo treatment sessions three times a week over an eight-month period, with assessments to measure functional recovery. The study seeks to address the inadequacies of current rehabilitation methods for upper limb recovery post-stroke.

Who should consider this trial

Good fit: Ideal candidates are individuals who have experienced a single ischemic stroke resulting in hemiplegia or hemiparesis, at least six months post-stroke, and have moderate to mild upper extremity function.

Not a fit: Patients with hemorrhagic strokes, multiple strokes, or those with active implanted stimulators will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve hand and arm function in stroke survivors, enhancing their quality of life.

How similar studies have performed: Other studies have shown promise with electrical spinal cord stimulation in similar neurological conditions, suggesting potential for success in this novel application.
