What this trial studies

This study explores the feasibility of using an EMG controlled device to enhance rehabilitation for stroke survivors with severe arm deficits. It aims to determine if this innovative technology can improve clinical outcomes beyond standard care during the acute phase of recovery. The study will assess the correlation between neurophysiological changes and the functional improvements achieved through the use of the device. Participants will engage in rehabilitation practices that leverage the device to potentially enhance neuroplasticity and recovery of arm function.

Who should consider this trial

Good fit: Ideal candidates are veterans over 18 years old who have experienced an ischemic stroke within the last 6 months and have severe arm impairments.

Not a fit: Patients who have had a hemorrhagic stroke or previous strokes affecting motor function on the opposite side may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the ability of stroke survivors to perform daily activities independently.

How similar studies have performed: While the use of EMG controlled devices in rehabilitation is a novel approach, previous studies have shown promise in enhancing recovery through innovative rehabilitative tools.
