ARC-EX Therapy

The first FDA-approved, non-invasive spinal cord stimulation to improve hand sensation and strength after chronic cervical spinal cord injury.

How it works

ARC-EX delivers gentle electrical stimulation through electrodes placed on the back of the neck while you practice real-world functional tasks — gripping, reaching, and self-care. Developed by ONWARD Medical, it is the first FDA-approved non-invasive spinal cord stimulation system of its kind.
The therapy is personalized, non-surgical, and used only in supervised rehabilitation settings like ours — integrated directly into your activity-based training so gains carry into daily life.
Who it's for
People living with chronic cervical spinal cord injury who are working to improve hand sensation and strength. Promising research is also underway applying this technology to other levels of spinal cord injury, as well as multiple sclerosis, stroke, and brain injury recovery.
