The Complex Regional Pain Syndrome (CRPS) Special Interest Group aims to:

  • Provide a forum for members to engage in free and frank communication on the diagnosis and management of complex regional pain syndrome with its variable clinical presentations.
  • Bring attention to new developments in the fields of basic and clinical research on CRPS.
  • Promote person-centred interdisciplinary research and care by integrating knowledge and expertise from basic science, medicine, psychology and rehabilitation science disciplines as well as lived experience (patient) reports about pain in complex regional pain syndrome.

Attention Early Career Researchers  

The CRPS SIG Officers are committed to promoting opportunities for Early Career Researchers. Therefore, we are pleased to announce that we have appointed an Early Career Researcher (ECR) to focus on the evaluation of treatments for CRPS.   

In his role as the ECR representative, Michael is working towards creating new opportunities for ECR members to engage with the CRPS-SIG. He is currently calling for expressions of interest from ECRs to present their CRPS research in a free online symposium, scheduled for 2023. 

If you are interested in presenting your work at the symposium or contributing to the ECR perspective of the SIG, please contact Michael at m.ferraro@neura.edu.au 

If you would like to feature your work on the CRPS Twitter feed or if you have news you would like to share on the CRPS page, please reach out to Tara Packham for more details or DM our Twitter account.
