In the past few years, there have been some pretty impressive breakthroughs for those suffering from partial paralysis, but a frustrating lack of successes when it comes to those who are fully paralyzed. But a new technique pioneered by scientists working on project NEUWalk at the Swiss Federal Institute for Technology (EPFL) have figured out a way to reactivate the severed spinal cords of fully paralyzed rats, allowing them to walk again via remote control.

And, the researchers say, their system is just about ready for human trials.

Previous studies have had some success in using epidural electrical stimulation (EES) to improve motor control in rodents and humans with spinal cord injuries. However, electrocuting neurons in order to get allow natural walking is no easy task, and it requires extremely quick and precise stimulation.

As the researchers wrote in a study published in Science Translational Medicine, "manual adjustment of pulse width, amplitude, and frequency" of the electrical signal being supplied to the spinal cord was required in EES treatment, until now.
