This is from Wikipedia article for phantom limb http://en.wikipedia.org/wiki/Phantom_limb
"One particularly novel treatment for phantom limb pain is the mirror box developed by Vilayanur Ramachandran and colleagues (Ramachandran, Rogers-Ramachandran & Cobb 1995). Through the use of artificial visual feedback it becomes possible for the patient to "move" the phantom limb, and to unclench it from potentially painful positions. Repeated training in some subjects has led to long-term improvement, and in one exceptional case, even to the complete elimination of the phantom limb between the hand and the shoulder (so that the phantom hand was dangling from the shoulder)."
In our society, I could see the following: the $10 sexily-marketed placebo pill / treatment must be better than the $2 knock-off, so people buy the $10 pill. Okay, they likely won't be buying $50k / year treatments, but all of a sudden the meds only cost cents to produce.
