This power point lists methods of obtaining proper diagnoses, documented by outcome studies, which prove the efficacy of these diagnostic methods. One case is point is the overdiagnosis of RSD or CRPS, where 71% of patients sent to the former president of the RSD Asssociation of America with the “diagnosis” of RSD actually had nerve entrapments, and no signs of RSD.
