Complex Regional Pain Syndrome

The SIG on Complex Regional Pain Syndrome (CRPS) aims to:

  • Provide a forum for members to engage in free and frank communication on the diagnosis and management of pain syndromes of the sympathetic nervous system.
  • Bring focus to new developments in the field in basic and clinical research.
  • Assimilate the views of the different medical disciplines and patient reports about pain and the sympathetic nervous system.

The IASP accepted criteria for CRPS follows:
Harden, R. N., Bruehl, S., Perez, R. S., Birklein, F., Marinus, J., Maihofner, C., Lubenow, T., Buvanendran, A., Mackey, S., and Graciosa, J. (2010). "Validation of proposed diagnostic criteria (the “Budapest Criteria”) for complex regional pain syndrome." PAIN, 150(2), 268-274. These criteria are described in the IASP Classification of Chronic Pain.


The IASP SIG on Complex Regional Pain Syndrome (CRPS) keeps an archive of published newsletters under its previous name of Pain and Sympathetic Nervous System (PSNS).
