I am the one who posted originally about the conference in San Diego. I was able to figure out how to copy the criteria for diagnosis of CRPS from my previous post.

They spent a long time discussing the difference between signs (something that the doctor sees upon examination), and symptoms (reported by the patient as happening at some time). They have decided that the doctors need to take both into account, not just what they see in the office. Hope this helps. If you want more detail, let me know. Sunny

CRPS diagnostic criteria from 1994 need to be changed [name was changed from RSD to Complex Regional Pain Syndrome (CRPS) because there was no evidence that the syndrome was necessarily a reflex or sympathetically mediated]. The old theory of stages is not valid, except for the progression of warm to cool; there may be subtypes instead.
New proposed criteria (from 2003 meeting in Budapest);
For a positive diagnosis of CRPS: Need--1. Continuous pain in the region disproportionate to the inciting event
2. At least one symptom in 3 or more of the following categories:
3. At least one sign in 2 or more of the following categories:
Categories: 1. Sensory: Allodynia; Hyperalgesia; Deep somatic allodynia
2. Vasomotor: Temperature; Color change/asymmetry
3. Sudomotor: Abnormal sweating; Edema
4. Motor/Trophic: Decreased range of motion; Skin, hair, nail changes
(Allodynia=pain from innocuous tactile stimuli; hyperalgesia=increased response to painful stimuli)
Diagnosis is made on clinical evaluation, but thermography, Quantitative Sweat Test, bone scan, diagnostic blocks, etc., may help support the clinical diagnosis. Lack of a positive response to SNS block does not mean it is not CRPS.
New guidelines for traditional treatment involve 3 core elements: rehabilitation (including physical therapy), pain management, and psychological treatment.
