'I dream of walking every other night', says wheelchair user

I dream of walking every other night. The dreams aren’t bitter. They’re charged with hope. It was this hope that led me to California to take part in clinical trials for a powered exoskeleton that is designed to help paralysed people like me walk again.

I’ve been using a wheelchair for the past 21 years after one day in May 1996 during what was supposed to be an idyllic vacation on the Greek island of Poros.
