Whatever you do, don't use this paper with any medical professionals. The guy who wrote it, Scott Reubens, was a complete fraud. He admitted eventually that he hadn't actually carried out any of his many clinical trials and had just made up all of the contents and results. It set back CRPS research enormously. His papers have all been pulled from web based journals and sources and any other papers that relied on his papers have had those aspects rendered equally meaningless and null. This made the mainstream news media at the time and I can remember RSDSA announcing that they were pulling all his papers from their site because they were fabricated.

Google his name and you will see the extent of his fraud.
