Standing on One Foot

Standing on one foot without any help?  This man did, four years after the accident that left him with a spinal cord injury.  After years of training with epidural stimulation, Andrew Meas has been “able to extend his knees, reach a standing position, maintain a standing position without assistance, and even stand on one leg" (to quote from Michelle Star's "Science Alert" article).  The unexpected result is that he has done all of these things without active electrical stimulation.  This is motor function recovery.
