This is the fifth edition of the Diagnostic and Treatment Guidelines for Complex Regional Pain Syndrome (CRPS; also known as Reflex Sympathetic Dystrophy [RSD], causalgia). These guidelines have been sponsored by the Reflex Sympathetic Dystrophy Syndrome Association and are written by expert practitioners in each discipline that is traditionally utilized in the treatment of CRPS . There is a fairly recent, excellent, rigorous systematic review of the treatment literature in CRPS  which confirmed there is only modest high-quality research in the area. Nonetheless, in this “evidence vacuum” we still have a responsibility to treat. Certainly, we must develop better evidence, but our patients cannot wait for that. Thus, although the authors of these practical guidelines all utilized a systematic approach to reviewing the available and relevant literature, they have also included less rigorous, preliminary research reports, often supplemented by extensive empirical experience. The authors perforce must also extrapolate from “related conditions” (e.g., neuropathy ). The research quality, clinical relevance and “state of the art” of diagnostic criteria or treatment modalities are discussed, sometimes in considerable detail. Where there have been no discernable updates in areas since the 4th edition, text from that has been kept, sometimes verbatim.
These guidelines are intended to serve as an aid to the informed practitioner. They are not intended to replace or supplant the clinician’s best judgment, experience, training and/or a careful consideration of the clinical context. Although every reasonable attempt has been made to minimize the bias of the authors, it must be recalled that, in context, all the experts are to a degree biased to “their” therapeutic approach.
Detailed sections are provided as a guide and informational source not only to the “expert” in CRPS therapy but also the primary practitioner who is interested. Levels of evidence are mentioned when appropriate (Table 1), so that the practitioner can better assess the modality under discussion and, if desired, to personally review the citations in detail. In the humanitarian spirit of making the most of all current thinking in the area, balanced by a careful case by case analysis of the risk/cost versus benefit analysis, we offer these “practical” guidelines.
