Painless spinal zaps may restore hand movement after paralysis

This study tested a new, non-invasive treatment for people with cervical spinal cord injury who have difficulty using their hands and arms. Fifteen participants received either electrical stimulation of the spinal cord combined with physical therapy, or physical therapy alone. The goal was to see if the stimulation could help rewire the spinal cord and improve motor control. The treatment was painless and did not require surgery.
