Abstract
Aim: To ascertain clinical features of complex regional pain syndrome (CRPS) in children with a focus on movement disorders. Methods: all publications with original data on children with CRPS were assessed. Data were tabulated and descriptive statistics were applied. Results: One population-based study and nine clinic-based studies provided data on demographic and clinical characteristics of childhood CRPS. Mean age of onset was 12.5 years and 85% of patients were females (risk ratio: 1.70; 95% CI: 1.54−1.88). History of trauma in 71% and the lower limbs were affected in 75% of patients. A secondary site involvement was present in 15%. Movement disorders and dystonia were reported in 30% of children. Conclusion: Majority of cases of CRPS in children are females with mean age of 12.5 years. Movement disorders (mainly dystonia) affect at least one in three children with CRPS.
