Phantom limb syndrome is when you lose a limb due to any tragedy, and you still feel pain in that lost limb, even when it does not exist. For instance, it can be an amputated leg, and neurons in the brain will send signals to a limb that is no longer there. The way that this happens is that the brain receives mismatch signals. Usually vision is what helps us move, and proprioception gives the brain constant feedback from the extremity or limb during movements. 

I wanted to represent the syndrome, so I decided to create a leg out of wire. This is shown in the images attached below. The wire includes random pieces of jacks, which portray the nerve signals that go along with your vision and proprioception that can make the individual feel pain in the nonexistent leg. 

In addition to creating the leg, I placed a mirror next to the limb to represent the lost leg. The image is attached below. This represents a therapeutic way of dealing with phantom limb syndrome. They place a mirror next to the existing leg, to make it look like the amputated limb exists. Thus, they perform symmetrical exercises thinking that their missing limb is there and moving.
