Complex regional pain syndrome type 1 (CRPS1) is characterized by pain, swelling, and sudomotor and motor dysfunction. The affected limb is exquisitely sensitive, and gentle movements can exacerbate symptoms. Local or spinal mechanisms, or both, may mediate symptoms, including pain. Evidence of altered sensorimotor processing suggests that symptoms may also be mediated by cortical mechanisms. This clinical note reports on findings from one patient with CRPS1 in whom imagined movement of the affected limb, without local muscle activity or movement, increased pain and swelling.
