BCI RoGO
Published on Jul 7, 2012

An able-bodied subject uses electroencephalogram (EEG)-based brain-computer interface (BCI) to operate a robotic gait orthosis (Lokomat, Hocoma, Volketswil, Switzerland). The subject is instructed by alternating 1-minute cues presented on the screen to idle (red) and walk (green) for a total of 5 minutes. The subject is 85% body-weight supported. There is a 5-7 second delay due to Lokomat's start-up and shut-down cycle.
This work, a collaboration between UC Irvine and Long Beach VA, represents the first successful integration of a BCI with a lower extremity prosthesis in humans. It carries implications for developing future devices to restore walking to individuals with paraplegia due to spinal cord injury and possibly for rehabilitation of those with incomplete motor injuries.

Person with Paraplegia Uses a Brain-Computer Interface to Regain Overground Walking
Published on Apr 21, 2014
Quote:
An individual with paraplegia due to spinal cord injury (SCI) uses electroencephalogram (EEG)-based brain-computer interface (BCI) to operate a functional electrical stimulator (Parastep, Sigmedics, Fairborn, OH) for walking. The subject is instructed by auditory cues to walk from one set of traffic cones to the next, while making ~10-20 second-long stops by the cones. For safety reasons, the subject is placed in a harness (ZeroG, Aretech, Ashburn, VA).
This work has been supported by the National Science Foundation, UC Irvine Institute for Clinical and Translational Sciences, and the Spinal Cord Injury Fund.

Brain-computer interface restores walking after paraplegia
Published on Sep 23, 2015
Quote:
Using an electroencephalogram (EEG) based system, the ability to walk has been restored following a spinal cord injury. 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. The participant, who had been paralyzed for five years, walked along a 3.66m long course using a system that takes electrical signals from his brain, which then travel down to electrodes placed around his knees to create movement.
