Electrical Pulses Help Paralyzed Patients Move

Four people who were paralyzed below the waist for more than two years were able to voluntarily wiggle their toes and flex their legs, thanks to a promising study that some are heralding as a breakthrough in spinal-cord-injury treatment.

The key to the achievement, say the study’s authors, was stimulation of the spinal cord using a commercially available electrical stimulator commonly used to treat pain. The device is surgically implanted just above the spine’s dura, in the epidura, where animal studies showed it could appropriately relay signals to the legs and lower extremities.
