Stop Pain: Complex Regional Pain Syndrome (CRPS)
This site covers all the bases for patients who need to know about complex regional pain syndrome. Visitors can read up on who gets the syndrome, symptoms, and treatment options. Under the “What Is Happening in My Body to Cause CRPS?” section, readers can learn about sympathetically maintained pain and the role it may play in CRPS. Or, they can simply open up the pop-up interactive flash module, sit back, and listen to the program, which covers all of these topics.

Reflex Sympathetic Dystrophy Syndrome Association
Direct your patients here to receive reliable information from one of the oldest associations dedicated to complex regional pain syndrome. Patients can read about how CRPS is diagnosed, as well as common symptoms. The site maintains updated collections of recent news, medical articles, research, and events for those who wish to become a part of the association or participate in an event. The website is “designed to give patients, family members, and healthcare professionals the most up-to-date information on treatment, legislation, support groups, research, fundraising, and patient stories.”

//Medical Websites Complex Regional Pain Syndrome: Treatment Guidelines
Take a look at the guidelines for complex regional pain syndrome featured at the Reflex Sympathetic Dystrophy Syndrome Association’s website. The new edition of the guideline was edited by R. Norman Harden, MD, director, Center for Pain Studies, Addison Chair, Rehabilitation Institute of Chicago. The site features the full-text guideline, from the table of contents to interventional therapies. The appendices on treatment algorithm, pharmacotherapy guide, and psychological intervention are
also included. A gallery of 16 photos accompanies the guideline as well.

//Online CME Module 5: Complex Regional Pain Syndromes
Fee: $30 (non-members), None
Expires: March 31, 2011
This activity is the fifth module in a series of CME activities under the palliative care umbrella. At the conclusion of this module, “participants should be able to understand the symptoms of Complex Regional Pain Syndromes (CRPS); distinguish CRPS1 from CRPS2; and discuss the treatment algorithm for CRPS.”

//eAbstracts Validation of Proposed Diagnostic Criteria (the “Budapest Criteria”) for Complex Regional Pain Syndrome
Journal: Pain (April 20)
Authors: Harden R, Bruehl S,
Perez R, et al.
Purpose: “This validation study compared current IASP diagnostic criteria for CRPS to proposed new diagnostic criteria (the “Budapest Criteria”) regarding diagnostic accuracy.”
Results: “Discriminating between diagnostic groups based on presence of signs or symptoms meeting IASP criteria showed high diagnostic sensitivity (1.00), but poor specificity (0.41), replicating prior work. In comparison, the Budapest clinical criteria
retained the exceptional sensitivity of the IASP criteria (0.99), but greatly improved upon the specificity (0.68).” The “inclusion of four distinct CRPS components in the Budapest Criteria contributed to enhanced specificity.”

Familial Occurrence of Complex Regional Pain Syndrome
Journal: Canadian Journal of Neurological Sciences (May 2010)
Authors: Shirani P, Jawaid A,
Moretti P, et al.
Purpose: To further study the etiology of complex regional pain syndrome (CRPS) and evaluate the idea that “different environmental and genetic factors” may contribute
Results: The team “reviewed the clinical data from a cohort of 69 patients with CRPS.” According to the data, “CRPS can be familial” and “may have a genetic basis in some
families.” The researchers concluded that “larger studies will be needed to ascertain clearer patterns of inheritance.”

Wherever Is My Arm? Impaired Upper Limb Position Accuracy in Complex Regional Pain Syndrome
Journal: Pain (June 2010)
Authors: Lewis J, Kersten P, McPherson K, et al.
Purpose: Researchers sought to “determine the degree to which experimental data supported the reported difficulty in limb position sense” for patients with complex regional pain syndrome.
Results: Results demonstrated evidence “of bilateral arm positioning impairments in unilateral arm CRPS,” which “suggests that central mechanisms are involved.” The team suggested cortical reorganization “in regions associated with the body” as one explanation.

Pregabalin vs Placebo as an Add-on for Complex Regional Pain Syndrome of the Upper Limb Managed by Stellate Ganglion Block
Study Type: Interventional
Age/Gender Requirements: 18-65 years (male/female)
Sponsor: Hamilton Health Sciences
Purpose: “The purpose of this study is to assess the efficacy of pregabalin
in patients with complex regional pain syndrome Type I and to determine
whether it provides clinically significant pain relief and whether it improves
functioning of the upper limb.”
