Portable Rehabilitation Interface (PoRI) for improving hand function after stroke

Randomized Clinical Trial of (PoRI) Post-Stroke Hand Rehabilitation Device

Not applicable Interventional Yale University · NCT07407023

This trial tests the PoRI portable hand-rehabilitation device to see if it helps people who recently had a stroke regain hand motor function compared with standard hand therapy.

What this trial studies

This is a randomized, controlled trial comparing a portable device-based therapy (PoRI) with conventional hand therapy in patients early after stroke. Participants are enrolled between 2 days and 2 months after their stroke and have reduced hand strength (0–3/5) or sensorimotor finger problems. The device must comfortably fit the participant's hand and allow passive range of motion to neutral; those who cannot meet those requirements are excluded. Treatments are delivered in Yale New Haven Hospital's Inpatient Rehabilitation Unit (Milford, CT) and outcomes focus on hand motor recovery and functional use.

Who should consider this trial

Good fit: Ideal candidates are people 2 days to 2 months after a stroke with significant hand weakness (0–3/5) or sensorimotor finger impairment who can fit their hand into the device and tolerate passive range of motion exercises.

Not a fit: Patients more than 2 months or less than 2 days after stroke, those with near-normal hand strength (4–5/5), those who cannot achieve neutral passive wrist/finger positioning, or vulnerable populations are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, PoRI could speed and improve hand motor recovery after stroke, leading to better hand function and reduced disability.

How similar studies have performed: Other robotic and device-assisted hand rehabilitation approaches have shown promise in improving post-stroke hand function, but PoRI is a specific portable interface being tested in this trial.
