Paralyzed rats walk again
September 21, 2009

In a breakthrough study funded in part by the Reeve Foundation, scientists at UCLA and the University of Zurich tested a three-part intervention to promote recovery of function in paralyzed rats.
The rats, whose spinal cords were completely transected, were given a combination of quipazine and epidural electrical stimulation, intended to activate the spinal cord's neural circuitry and make it functional once again. Then the rats were given locomotor training. The combination was extremely effective: the animals were able to fully bear weight on the treadmill and their locomotion was almost indistinguishable from their voluntary stepping before injury.
Published online in Nature Neuroscience (20 September 209), the study was led by V. Reggie Edgerton, PhD and Gregoire Courtine, PhD. Dr. Edgerton is a member of the Reeve Foundation's International Research Consortium on Spinal Cord Injury and Dr. Courtine, now an independent scientist in Zurich, is a former Consortium Associate from the Edgerton lab.
