Here's  an amazing story to end your week on a high note: a 25-year-old  paraplegic is now walking again, thanks to a groundbreaking procedure  developed by neuroscientists at the University of Louisville, UCLA and  Cal Tech. The Oregon man, Rob Summers, was paralyzed below the chest in  2006, after getting hit by a speeding car. This week, however, doctors  announced that Summers can now stand up on his own and remain standing  for up to four minutes. With the help of a special harness, he can even  take steps on a treadmill and can move his lower extremities for the  first time in years. It was all made possible by a spinal implant  that emits small pulses of electricity, designed to replicate signals  that the brain usually sends to coordinate movement. Prior to receiving  the implant in 2009, Summers underwent two years of training on a  treadmill, with a harness supporting his weight and researchers moving  his legs. This week's breakthrough comes after 30 years of research,  though scientists acknowledge that this brand of epidural stimulation  still needs to be tested on a broader sample of subjects before any  definitive conclusions can be drawn. Summers, meanwhile, seems  understandably elated. "This procedure has completely changed my life,"  the former baseball player said. "To be able to pick up my foot and step  down again was unbelievable, but beyond all of that my sense of  well-being has changed." We can only imagine.
