Researchers have long known that simply viewing an image of an amputee's intact foot or arm in a mirror can sometimes help
relieve phantom pain, as if the brain's sense of self adjusts its conflicting sensations about the missing limb.
The new findings parallel previous work demonstrating that adding more sensory input can
relieve chronic
phantom limb
pain experienced by some amputees: when a mirror tricks the brain into thinking the body is whole again, the
pain subsides.
