Factors influencing disability and work absence in complex regional pain syndrome type-1 (CRPS)-1 have not been thoroughly described in the literature. We sought to determine whether demographic variables, work-related factors, CRPS clinical severity ratings, pain scores, or psychological variables were associated with disability and sick leave in early CRPS-1. ⋯ Although the study was cross-sectional and so cannot differentiate cause from effect, results suggest that even in the early stages of CRPS, a cycle of pain, disability, depression, and work absence can emerge. Treatments aimed to prevent this cycle may help prevent adverse long-term outcomes.
