Watch the heart-warming moment a paralysed chimpanzee walks for first time in six years with the help of a touch-screen

A chimpanzee has learned to walk again after an illness left him paralysed. The male, named Reo, was 24 when part of his spinal cord became inflamed, rendering him unable to move. Now, ten years later, thanks to a dedicated programme of training using a touch screen and reward training, he is able to walk again. Lead author Yoko Sakuraba of Kyoto University described the triumph in an article in Primates, the official journal of the Japan Monkey Centre. The study marks the first time a dedicated training progamme using touch screen technology to study chimpanzees' cognitive abilities has helped a chimp recover after paralysis.
