Longitudinal Follow-up Study About Complex Regional Pain Syndrome (CRPS) Patients

Complex regional pain syndrome (CRPS) is a post-traumatic chronic pain condition characterized by pain and other symptoms typically affecting a distal limb. Relatively little is known about the prognosis of the course of CRPS .Currently there is no specific test to diagnose CRPS. The primary objective of the study is to investigate prospectively the evolution of CRPS and the impact of the psychosocial factors on health status, recovery, quality of life, and working status of CRPS patients. The secondary objective of the study is to measure blood parameters in CRPS patients to investigate their evolution during the course of CRPS, and maybe to identify distinctive biomarkers associate with CRPS and that could be potential candidate for diagnosis.
