SANCHEZ PRADO, Einer et al. Associated factors related to the development of sequels in a group of patients with complex regional pain syndrome type 1 (SUDECK). Rev. argent. reumatolg. [online]. 2019, vol.30, n.4, pp.14-17. ISSN 0327-4411.

Background/Purpose: complex regional pain syndrome (CRPS) is a form of chronic pain that usually affects an arm or a leg. CRPS typically develops after an injury, a surgery, a stroke or a heart attack. The pain is out of proportion to the severity of the initial injury. CRPS is uncommon, and its cause isn't clearly understood. Methods: To estimate the percentage of patients with CRPS who develop disability and its associated factors. Consecutive patients older than 18 years old whose met Budapest criteria for CRPS type 1 were included. Demographic variables, time of follow-up, main cause of the disease and location, time between trauma and starting treatment were recorded from the electronic clinical history (ECH). Previous immobilization, type were recorded of treatment, response to it and clinical manifestations. Disability was defined when there was a change in work activity. Results: 98 patients were included with at least one year of follow up, 65.3% were women. The median age is 54 years (45-61). The prevalence of disability was 60%. We found a significant and independent association with indication of rehabilitation (OR: 4.3 CI: 1.3-14) and response to treatment (OR: 0.078 CI: 0.023-0,2). Conclusion: 60% of the patients developed disability in their follow-up, they were associated independently with the indication of rehabilitation and in a negative way with a good response to treatment.
