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.

IASP 2020 World CongressUpcoming CRPS SIG Meetings!

Our next CRPS SIG satellite meeting will be in Amsterdam in August 2020 at the IASP World Congress on Pain. In 2019, we encourage members to attend the Congress of the European Pain Federation EFIC in Valencia September 4-7. As a part of EFIC, leaders in the field of CRPS research will present a workshop, “New Aspects of Complex Regional Pain Syndrome” on September 5, 2019 from 10:30-12:00 PM.
