Paralyzed rat is able to walk again thanks to exoskeleton

Humans have exoskeletons to help us carry some really heavy stuff around, as well as perhaps help the paralyzed to walk again. How about animals? Well, this is one animal testing procedure that we hope will succeed to so that similar technology can be ported over to help humans walk again, without harming any lab rats in the process, of course. Scientists have managed to electrically stimulate the severed part of the spinal cord in order to control the limbs of a paralyzed rat in real time, and with the success of this experiment, it is said that human trials are set to begin.
