Medical device, brainwaves retrain paralyzed hand

Columbus, Ohio – A scientific study, at The Ohio State University Wexner Medical Center and based on an invention from Battelle, has enabled a quadriplegic Ohio man to regain his ability to pick up objects, stir liquids, and even play video games – using his own thoughts. Ian Burkhart of Dublin, Ohio, first made headlines in June 2014 when he became the first paralyzed patient to use neural bypass technology, NeuroLife, to pick up and hold a spoon using his own thoughts.

“Today, when he’s hooked up to the system, he’s able to swipe a credit card, hold a bottle up to his mouth, and pick up a phone,” says Dr. Ali Rezai, CEO of Ohio State's Neurological Institute. “We’re thrilled how far Ian has come in just over a year. Several years after a spinal cord injury, his level of function has improved significantly. That has never been demonstrated before.”

Back in 2014, Rezai implanted a chip into Ian’s brain. Wires from that chip connect to a computer containing algorithms that decode his thoughts and translate them into action impulses for a sleeve on his arm. For the past two years in hundreds of sessions at Ohio State, Burkhart has become more proficient at performing complex, functional tasks with his right hand as he learns the system and the system learns from him.

“It creates what we call a neural bypass,” said Nick Annetta, a researcher and electrical engineer at Battelle, which developed the NeuroLife system. “We’re able to turn Ian’s thoughts into signals that bypass his injured spinal cord, and send them directly to the sleeve, causing his muscles to move. It really is incredible.”
