Graded Motor Imagery to Treat Complex Regional Pain Syndrome

Complex regional pain syndrome (CRPS) is a painful condition localized to a limb or body region, typically in response to trauma or surgery. Although several contributing mechanisms of CRPS have been described, the exact pathophysiology of the condition is not completely known. Graded motor imagery (GMI) is a comprehensive program aimed at sequentially activating motor cortical networks of the disordered limb to improve neural reorganization. GMI includes phases of progressive sensory-motor restructuring beginning with laterality training, guided imagery, and ultimately leading to mirror therapy. In this lecture, leading mechanisms for the development of CRPS will be discussed, along with the role of reorganization of the somatosensory cortex. In addition, treatment algorithms will be included along with medications, injections, and a thorough review of GMI and its outcomes. (Recorded at PAINWeek 2018)
