Researchers said that a quadriplegic person is able to move four of his paralyzed limbs using a robot-controlled robotic suit.

News agency AFP reported that a 28-year-old man named Thibault of France was paralyzed from the shoulder after falling 40 feet from a balcony.
There was some movement in his biceps and left wrist, and he could drive a wheelchair using a joystick with his left hand.

Researchers at the University of Grenoble in France, the Cleantech Biomedical Research Center and the CEA Research Center implanted recording devices between the brain and the skin on each side of the head of the thimble to cover the brain area that controls the sensor's motor sensors. Does. And condolences
The electrode network collected brain signals from humans and transferred them to a decoding algorithm, which translated the signals into movements and ordered a robotic exoskeleton to complete them.
Over a period of two years, Thibault trained the algorithm to control an avatar, a virtual character within a video game, and to understand his ideas for moving and touching 2D and 3D objects.

He trained in simple virtual simulations before using the exoskeleton, which is assisted by a harness mounted on the roof to finally walk and reach the target with his arms.
During the study, Thibault covered a total of 145 meters (about 476 feet) with 480 steps using a combined embodiment, video and exoskeleton, the researchers said in the study, which was published in The Lancet Neurology on Friday.
Scientists have said that technology is an experimental treatment for now, but once improved, it may have the potential to improve patients' lives.
Thibault told AFP, "I can't go home tomorrow in my exoskeleton, but I've reached a point where I can walk. I want and can stop whenever I want."

"Our findings may take us a step further to help tetraplastic patients manage computers using only brain signals, perhaps starting in a wheelchair using brain activity instead of joysticks and an exoskeleton for greater mobility. do." A neurosurgeon at Grenoble University Hospital and author of the study said in a press release.
The team has recruited three more patients for the trial and aims to allow patients to walk and swing without using the roof suspension system in the next phase of the investigation.
