"I was like, should we enroll this participant?"

M'zee lost the use of his legs due to a sporting accident but thanks to researchers at the Swiss Federal Institute of Technology in Lausanne, Switzerland, he can reportedly walk more than a half mile, hands free, with the implants turned on.

This latest study, called STIMO (STImulation Movement Overground), establishes a new therapeutic framework to improve recovery from spinal cord injury.

For Courtine, Bloch, and their colleagues, the next step is to explore results in people with recent injuries, where "the potential for plasticity is elevated and the neuromuscular system has not yet undergone the atrophy that follows chronic paralysis", they write. 'Unbelievable!' Courtine's postdocs said.

The field of spinal cord injury is poised to take a giant leap forward in the treatment of what was until very recently considered incurable: "paralysis".

The two previous studies appeared in Nature Medicine and The New England Journal of Medicine. In most spinal cord injuries the spine is not severed, but bruised. The devices also helped the damaged nerves of the spine to regrow and restore some of the activities.

Pilot arrested for blowing 10 times over limit before flight
Katsutoshi Jitsukawa, 42, was arrested after being reported to police when an airport bus driver smelled alcohol on him. Tests revealed he had 189mg of alcohol per 100ml of blood in his system, nearly 10 times the 20mg limit for a pilot .

"Specific configurations of electrodes are activated to control the appropriate groups of muscles, mimicking the signals that the brain would deliver to produce walking", explained co-researcher Dr. Jocelyne Bloch, a neurosurgeon with Lausanne University Hospital.

There were three of the total paralyzed men who were told that they wouldn't be able to walk again in their lives and they would spend the rest of their lives by simply being in wheelchairs. 'That's one of the most exciting parts of this, ' says Chet Moritz, a neuroscientist at the University of Washington who was not involved with the new work.

"I can support more and more weight on my legs and have more and more control with my legs", said Tobler, 47, who had both legs completely paralyzed after a 2013 mountain biking accident.

Every good thing can be improved, so research about spinal cord electrical stimulation continues. When Courtine had the implant fire continuously in the same patients, that coordination went away. "It is also this spatiotemporal coincidence that triggers the growth of new nerve connections", says Courtine. During the study, they used electrical stimulation to give motor neurons extra excitement and boost the remaining connections to the brain. That in turn makes it hard for the spinal cord to coordinate movement, says Jocelyne Bloch, a neurosurgeon at Lausanne University Hospital who worked on the new studies. 'The collision of signals is confusing the brain and the patient, ' she says. His left leg has been paralyzed ever since 2010, but now, thanks to the spinal cord stimulation, he can perform operations like extending the knee, moving toes and flexing the hip.

"Nerve fibers are growing again". This implant helped them walk. 'Two of them can walk long distances with crutches, ' he adds. "The patients - they have to do it". And others began having more sensation in parts of their upper bodies. David when was asked about this, he told that this treatment really meant a lot of him and he was surprised that how this really worked and what could have he done if he was not able to walk. Gert-Jan Oskam could only make slight movements with his legs before the trial, but now he says he can stand to do simple tasks at home-including cooking and grilling.
