Ian Burkhart, 24, plays a guitar video game as part of a study with neural bypass technology.
Ian Burkhart was only 19 when the accident happened. He had been swimming in the Outer Banks with some buddies when a wave caught him and hurled him into a sandbar, leaving him paralyzed from the neck down. But he always held out hope that medical science would one day be able to help him regain enough movement to become more independent.
That day has finally arrived.
Scientists reported Wednesday in the journal Nature that they have been able to implant a chip in Burkhart's brain that sends signals to an array of 130 electrodes embedded in a "sleeve" he wears on his arm that has given him the ability to move his hand with significant accuracy. Holding a glass with water and pouring it out. Using a stick to stir the contents of a jar. Playing Guitar Hero. Swiping a credit card.
These are the movements of mundane, daily life that many of us take for granted. But for Burkhart it's nothing short of a miracle.
"The first time I was able to open and close my hands it really gave me a sense of hope for the future," Burkhart, now 24, said in a call with reporters.
Lead researchers Chad Bouton, Nick Annetta and Ali Rezai said the effort took a multi-disciplinary team of scientists from neurosurgery to electrical engineering. The technique they used involves reconnecting the brain to the body by bypassing the damaged spinal cord.
For the interface to work, Burkhart concentrates on the movement he wants to make and a computer connected to the chip translates those signals into something his muscles understand. It turns out that each person has his or her own unique language that makes the machine a kind of "interpreter."
The study marks the first time a paralyzed patient has been able to regain movement in his own body - a total of six different wrist and hand motions - by using signals that originated within the brain.
"We were not sure this would be possible. This result really exceeded our expectations," said Bouton, a researcher at the Feinstein Institute for Medical Research in Manhasset, N.Y.
The system was tested and fine-tuned by Burkhart during up to three sessions a week for 15 months after the surgery to implant the chip in the motor cortex region of his brain.
The breakthrough is one of a number of recent advances in brain-computer interfaces for paralysis. In December 2012, scientists from the University of Pittsburgh helped Jan Scheuermann, who is quadriplegic, grab chocolate and put it to her mouth with a robotic appendage. Others have been experimenting with similar treatments for people with Lou Gehrig's disease and stroke.
Throughout the world, millions of people are living with full or partial paralysis, and the achievement marks what scientists say may be a new era in the types of treatment available to them. While the interface can only be used in the lab at this time, Annetta, an electrical engineer at the Battelle Memorial Institute, said their immediate goals include miniaturizing the equipment and making it more practical for patients so they can use it in their homes or out and about in their communities.
"This opens up so many opportunities now that we know it's possible," Bouton said.

These are the movements of mundane, daily life that many of us take for granted. But for Burkhart it's nothing short of a miracle.
Burkhart was paralyzed from the shoulders down after an accident in 2010, but regained functional use of his hand through the use of neural bypass technology.
