Implant Helps Paralyzed Man Stand, Take Steps: Electrical Stimulator Gives Portland Man Ability to Move His Legs

LONDON — After Rob Summers was paralyzed below the chest in a car accident in 2006, his doctors told him he would never stand again. They were wrong.

Despite intensive physical therapy for three years, Summers' condition hadn't improved. So in 2009, doctors implanted an electrical stimulator onto the lining of his spinal cord to try waking up his damaged nervous system. Within days, Summers, 25, stood without help. Months later, he wiggled his toes, moved his knees, ankles and hips, and was able to take a few steps on a treadmill.

"It was the most incredible feeling," said Summers, of Portland, Oregon. "After not being able to move for four years, I thought things could finally change."

Still, despite his renewed optimism, Summers can't stand when he's not in a therapy session with the stimulator turned on, and he normally gets around in a wheelchair. Doctors are currently limiting his use of the device to several hours at a time.

His case is described in a paper published Friday in the journal, Lancet. The research was paid for by the U.S. National Institutes of Health and the Christopher and Dana Reeve Foundation.
For years, certain people with incomplete spinal cord injuries, who have some control of their limbs, have experienced some improvement after experiments to electrically stimulate their muscles. But such progress had not been seen before in someone with a complete spinal cord injury.

"This is not a cure, but it could lead to improved functionality in some patients," said Gregoire Courtine, head of experimental neurorehabilitation at the University of Zurich. He was not connected to Summers' case. Courtine cautioned Summers' recovery didn't make any difference to the patient's daily life and that more research was needed to help paralyzed people regain enough mobility to make a difference in their normal routines.
