Man walks again
after years of paralysis

walk again.

The ability to walk has been restored following a spinal cord injury, using
one's own brain power, according to research published in the open access Journal of NeuroEngineering and Rehabilitation. The preliminary
proof-of-concept study shows that it is possible to use direct brain control to
get a person's legs to walk again.

This is the first time that a person with complete paralysis in both legs
(paraplegia) due to spinal cord injury was able to walk without relying on
manually controlled robotic limbs, as with previous walking aid devices.

The participant, who had been paralyzed for five years, walked along a
3.66m long course using an electroencephalogram (EEG) based system. The system
takes electrical signals from the participant's brain, which then travel down
to electrodes placed around his knees to create movement.

Dr. An Do, one of the lead researchers involved in the study, from University
of California, Irvine, USA, says: "Even after years of paralysis the brain
can still generate robust brain waves that can be harnessed to enable basic
walking. We showed that you can restore intuitive, brain-controlled walking
after a complete spinal cord injury. This noninvasive system for leg muscle
stimulation is a promising method and is an advance of our current
brain-controlled systems that use virtual reality or a robotic
exoskeleton."

Mental training was initially needed to reactivate the brain's walking
ability. Seated and wearing an EEG cap to read his brainwaves, the participant
trained to control an avatar in a virtual reality environment. He also required
physical training to recondition and strengthen his leg muscles.

The participant later practiced walking while suspended 5cm above ground,
so he could freely move his legs without having to support himself. On his 20th
visit, he translated these skills to walk on the ground and wore a body-weight
support system for aid and to prevent falls. Over the 19 week testing period,
he gained more control and performed more tests per visit.

This proof-of-concept study involved a single patient so further studies
are needed to establish whether these results are true for a larger population
of individuals with paraplegia.

Dr. Zoran Nenadic, the senior lead researcher of the study, from University
of California, Irvine, USA, says: "Once we've confirmed the usability of
this noninvasive system, we can look into invasive means, such as brain
implants. We hope that an implant could achieve an even greater level of
prosthesis control because brain waves are recorded with higher quality. In
addition, such an implant could deliver sensation back to the brain, enabling
the user to feel their legs."
