From Martin Gregorie
I would like to pass on a personal observation related to the rubber hand illusion (15 October, p 34). I am a below-the-knee amputee and periodically have twinges of phantom limb pain. Where I have the sensation depends on circumstances. If I’m wearing my prosthesis, the pain feels as if it is in my (missing) foot, but if I’m not wearing it, then I feel the pain in my stump. This is independent of whether I can see my legs or not.
