"All the patients could walk using body weight support within one week", says Blotch. "After a few months, participants regained voluntary control over previously paralysed muscles without stimulation and could walk or cycle in ecological settings during spatiotemporal stimulation", Fabien Wagner and his colleagues wrote in the study.

After several months of intense physical therapy, the patients could start walking hands-free.

The study achieves an unprecedented level of precision in electrically stimulating spinal cords, which the researchers said was "as precise as a Swiss watch".

"It was the first time I've seen the recovery of voluntary movement without stimulation, which is true neurological recovery", Professor Courtine said.

"If we can stimulate the central nervous system and peripheral nervous system at the same time, the additive effects could restart touch perception and movement in some people".

Most people don't have to think about walking.

"This opens a completely novel avenue for spinal cord injury rehabilitation".

But scientists have been hopeful that these nerve pathways in the spinal cord can be repaired by tapping into certain populations of nerve cells, called neural circuits, that are found in the spinal column. Now, the latest of three recent studies might prove them wrong.

A man with a spinal-cord injury leaving him wheelchair bound has been able to walk thanks to a revolutionary new spinal implant. During the study, they used electrical stimulation to give motor neurons extra excitement and boost the remaining connections to the brain. This device, manufactured by Medtronic, is already on the market for deep brain stimulation for Parkinson's disease. There are some connections still intact, but might not be enough to allow mobility. "It's turning up the volume, turning up the excitability of the spinal circuits below the injury".

However, neurostimulation for paralysis is still in its early stages, and scientists don't know exactly how it works to restore movement, says Kristin Zhao, an investigator at the Mayo Clinic and author of one of the September papers.

David M'zee, a 30-year-old Swiss man who was told by doctors he would never walk again after a sporting accident, is now able to walk around half a mile with the implant turned on. The team's cocktail ofneuronactivating chemicals and electrical stimulation might be a precursor to future treatments for disabled humans, researchers say. Continuous electrical stimulation of the spine may overwhelm communication the lower limbs are trying to send to the spinal cord, Courtine and his colleagues report in a second paper also published Wednesday in Nature Neuroscience.

While the results are exciting, it's important to keep in mind that paraplegics have other needs that go beyond walking, Moritz adds.

Previous studies have revealed that "the spinal cord has its own intelligence system that controls walking", said Dr. Thomas Oxley, director of innovation strategy for the Mount Sinai Health System Department of Neurology in New York City. "It doesn't need the brain to walk", Oxley said.

Even within the small group of three patients, the results have been markedly different.

Breakthrough: Spinal cord injuries can severely reduce a person's range of motion or lead to complete leg paralysis.
