A man who was left paralyzed following a motorcycle accident 12 years ago can now walk, climb stairs and complete chores thanks to computer-aided brain and spinal cord implants.

Gert-Jan Oskam, 40, of the Netherlands, lost control of his legs and much of his arms after a horrible crash while in China, with doctors telling him he would never walk again.

Not one to give up, Oskam underwent years of physical therapy and eventually joined the Swiss Federal Institute of Technology’s “digital bridge” project, which installed implants into his brain and spine in 2017 that can now connect to an external computer worn as a backpack.

By donning a special headpiece, signals from Oskam’s brain commanding his body to move are transmitted to his spinal cord, prompting his legs to walk as he sees fit, according to the proof-of-concept study published Wednesday in Nature.

Oskam said the technology, developed by Onward, has been life changing, allowing him to complete simple chores by himself.

“Last week, there was something that needed to be painted and there was nobody to help me. So I took the walker and the paint, and I did it myself while I was standing,” he told reporters on Tuesday.

Study author Prof Grégoire Courtine said Oskam’s progress has been astounding compared to the condition he came to them in.

“When we met him, he was completely paralyzed, unable to take a step by himself without assistance,” he told NBC.

When Oskam had the initial implants put in, he regained some of his motor functions, but he said his movements were still strained, and the machines at the time couldn’t keep in rhythm with his thoughts.

With his physical therapy plateauing by 2021, he decided to join the proof-of-concept study to see if things would change.

“The stimulation before was controlling me, and now I’m controlling the stimulation,” Oskam said of the new tech.

He noted that he can walk between 330 to 660 feet per day and can stand unsupported for at least two minutes.

Onward said that the system Oskam is using has additional trials planned over the next 12 to 18 months, and that four other people will receive the same implants to help them restore motion to their hands and legs.

Courtine is optimistic that Oskam’s case and the new technology will pave the way to helping many others walk again.

“There is no reason why it would not apply to the vast majority of people with spinal cord injury,” he said.
