Nerves inside paralysed people’s bodies have been “rewired” to give movement to their arms and hands, say Australian surgeons.

Patients can now feed themselves, put on make-up, turn a key, handle money and type at a computer.

Paul Robinson, 36 from Brisbane, said the innovative surgery had given him independence he had never imagined.

Completely normal function has not been restored, but doctors say the improvement is life-changing.

How does the procedure work?

Injuries to the spinal cord stop messages getting from the brain to control the rest of the body. The impact is paralysis.

Patients in the trial had quadriplegia affecting movement in all their limbs.

But crucially they were still able to move some muscles in their upper arms.

The functioning nerves leading from the spinal cord to these muscles were then rewired.

The nerves were cut and then attached to nerves that control other muscles – such as for extending the arm or opening or closing the hand.

For example, nerves that once turned the palm up to face the ceiling could be used to extend all the fingers in the hand.

So now when a patient thinks of rotating their hand, their fingers extend.

“We believe that nerve transfer surgery offers an exciting new option, offering individuals with paralysis the possibility of regaining arm and hand functions to perform everyday tasks, and giving them greater independence and the ability to participate more easily in family and work life,” said Dr Natasha van Zyl from Austin Health in Melbourne.
