Technology Helps A Paralyzed Person Change Thought Into Motion

Ian Burkhart prepares for a training session in Columbus, Ohio. To move muscles in Burkhart's hand, the system relies on electrodes implanted in his brain, a computer interface attached to his skull, and electrical stimulators wrapped around his forearm.

Ian Burkhart was paralyzed right into a wave in shallow water after diving in 2010. The injury left him with some arm motion but no usage of his hands.

Subsequently, about a couple of years back, scientists in Ohio equipped Burkhart hand together with his ideas and having a method that enabled him to control his right wrist.

After many months of training, Burkhart can perform jobs like swiping a credit card by means of a card reader, taking small things, and pouring water from a bottle. He also can control the motion of individual fingers.

It is all possible due to technology that intercepts and decodes electric signals from the mind before they reach the damaged back of Burkhart.

The device relies on electrodes planted in the brain, a computer interface attached to his skull of Burkhart, and electric stimulators wrapped around his forearm. It was created with a team in Columbus, Ohio, at Ohio State University and Battelle Memorial Institute.

Initially, Burkhart could take things, when he transferred his arm, however he’d drop them. Though, Bouton says his ability has improved steadily.

“Ian is learning the best way to think about quite comprehensive movements as well as the machine is really learning just how to decipher those signs more efficiently as well,” Bouton says. “So they are really learning collectively.”

Burkhart’s accomplishments have received a lot of media interest.

“The brain computer interfacing they did is sort of garden variety,” Kirsch says. “As well as the electric stimulation they’ve done is truly old fashioned.”

Other groups have got better results using electric stimulators which can be planted in muscles, instead of put on skin, Kirsch says. That strategy needs operation that is additional but enables more exact control of muscles, he says.

In a scientific meeting a year ago, a part of Kirsch’s team reported on someone using their technology who’s in a position to make use of muscles to be triggered by ideas in the arm and hand. That is significant, Kirsch says, because, unlike Burkhart, many other individuals that are paralyzed don’t have any usage of the arms or shoulders.

Over a decade of experiments has demonstrated that paralyzed individuals can learn how to work with their ideas to robotic arms control computers as well as their own limbs, says a professor of engineering at Brown University, Leigh Hochberg. Sadly, the systems which make this potential still aren’t unsuitable for use at home, he says.

And that, he says, will need technical progress — including the capacity to carry signals in the brain.

However, other paralysis research workers along with Hochberg say the delay will most likely be measured in years, not decades.
