This is Jasper, a 10-year-old dachshund, after he got hit by a car:
Here he is after the study:
Like several of the 23 dogs in the study who received the treatment, Jasper could soon walk on a treadmill with a harness. Many of the others regained at least some mobility in their hind legs.
Jasper had a slipped disc as a result of the accident in 2008. His owners had been using a trolley with a sling to help him get around. They say that now, "we can't stop him whizzing around the house, and he can even keep up with the two other dogs we own. It's utterly magic."
The research holds out hope that the same technique may eventually be used to restore at least some movement to humans with spinal cord injuries, although the researchers cautioned that a lot more research is still needed before that can happen.
