Cause and Treatment of Phantom Limb Pain in Amputees Discovered

Scientists have found why amputees feel the sensation of phantom limb pain. It is due to this reorganization pain occurs in the amputated limbs of a vast majority of amputees. The researchers also found a proposed way of treating the affliction through the use of artificial intelligence techniques. The researchers used a brain-machine interface to come up with this conclusion. They trained a group of ten amputees so they could control a robotic arm from their brain. The research team found learning to control the prosthetic through the amputated arm resulted in pain.
