Dutchman, Gert Jan Exam, has regained his ability to walk using a device that acts as a link between the brain and muscles to issue and implement movement orders.
A medical device has allowed a paralyzed man to walk normally again, more than a decade after the injury.
Dr. Grégoire Courtine and his colleagues at the Ecole Polytechnique Fédérale de Lausanne have developed and implanted a device that secures a link between the brain and the spine, establishing a direct neural connection between the brain and the spinal cord.
How does the device work?
The device requires tiny implants to receive movement commands in the brain and transmit the intent to move those commands wirelessly from the patient’s brain to a processing unit that the patient wears like a backpack. Tiny receptors in the brain convert the intentions into commands for the processing unit to send back through the second implant to stimulate the muscles.
How did the man become paralyzed?
Dutchman, Gert, was paralyzed in an accident that injured his neck while cycling in 2011. Thanks to the new device, he was able to stand and walk after doctors implanted the device which recognizes his brain waves and sends instructions to his spine. to move the muscles. Gert was able to climb stairs and walk approximately 100 meters in each trial after the device was implanted.
