Groundbreaking brain implants have restored hand control — and hope — for a man who became paralyzed after a diving accident.
Keith Thomas, who became paralyzed from the chest down after a pool accident, has regained control over his hands through a groundbreaking medical study involving brain implants.
Conducted by Northwell Health, Thomas underwent a surgery where five small chips were implanted into his brain in a procedure known as a double neuro bypass. The chips send and interpret signals between his brain, damaged spinal cord and hands, allowing him some movement. "We are literally pulsing very intense electrical patterns, but very briefly, that activates those circuits, those damaged circuits that are in his spinal cord and then we believe it's starting to strengthen those connections. There's a saying that neurons that fire together, wire together," said engineer Chad Bouton, who leads the Neural Bypass Lab in New York.
Before the accident, independence was everything to Thomas, although he said he took it for granted. The former finance professional had an active social life, going out to dinner with clients almost every night of the week. "When I first got home, I didn't get out of bed. I got out of bed once a day for six months," Thomas said."I cried all the time. I was crying cause I didn't have independence.
Michelle Bennett, his sister, remained a constant source of support. The accident brought them closer and Bennett said even when Thomas was still in the hospital and intubated, she remained positive about her brother, because she witnessed glimmers of the fun-loving Thomas despite his challenges."In September, he goes, 'Michelle, I'm just so hungry.' Because he couldn't eat yet. He'd been hungry since August," she said.
