AbstractPoststroke Complex Regional Pain Syndrome (CRPS) affects a significant number of moderate to severely impaired stroke survivors. Until recently, advances in the assessment and management of CRPS have been limited due to the lack of a consensus on diagnostic criteria; however, with the development of the International Association for the Study of Pain diagnostic criteria, the medical and scientific communities are poised to make significant strides. Biomechanical factors and microtrauma to the hemiparetic shoulder may have a significant role in the genesis of CPRS, although the exact pathophysiology that links these triggers to the observed disease manifestation remains uncertain. Sympathetic dysfunction has historical importance in the CRPS literature. However, this appears to be only one of several possible pathophysiologic mechanisms; somatic nervous system dysfunction, inflammation, hypoxia, and psychological factors are also likely contributors to the disease process. There is no definitive treatment for CRPS, and most patients are treated empirically. Nevertheless, there is consensus that the treatment approach should be interdisciplinary with the goals of edema and pain control, maintenance of joint and muscle biomechanics, and functional restoration. As more rigorous clinical trials emerge, the treatment approach will become more rational with selection of interventions based on a specific mechanism or a combination of mechanisms responsible for a given individual's disease manifestation.
