A man confined to a wheelchair is able to walk again after United States scientists reconnected his brain and legs.

It is the first time a paraplegic patient who was completely paralysed from the waist down after a spinal cord injury has been able to walk without relying on manually operated robotic limbs.

Neurosurgeons transmitted signals from the 26-year-old's brain to electrodes in his knees. "The brain can still generate brain waves that can be harnessed to enable walking," study leader An Do said.
