Manchester researchers devise 3D phantom limb

15/11/2006

Researchers at the University of Manchester have designed a computer program that allows amputees to move a 3D 'phantom limb'.

It is hoped that the 3D computer graphics program could help those who suffer from phantom limb pain (PLP) a condition where pain is felt in the amputated limb due to signals from nerve endings.

People who suffer from PLP often experience the sensation that the amputated limb is still attached to the body.

The researchers believe that the virtual reality device tricks the brain into believing a limb is present, thereby reducing the pain.

By means of sensors and a headset, patients are able to 'see' and 'move' fingers, hands, feet, arms and legs.

Although the study was limited to five patients from Greater Manchester, four of them reported almost immediate pain reduction.

Dr Craig Murray, who led the research, said: "One patient felt that the fingers of her amputated hand were continually clenched into her palm, which was very painful for her.

"However, after just one session using the virtual system she began to feel movement in her fingers and the pain began to ease."

According to research, up to 80 per cent of amputees are said to experience painful, phantom sensations in their amputated arm or leg.
