Traumatic neuralgias: complex regional pain syndromes (reflex sympathetic dystrophy and causalgia): clinical characteristics, pathophysiological mechanisms and therapy.
Complex regional pain syndromes (CPRS) may develop as a disproportionate consequence of a trauma affecting the limbs without (CRPS I, reflex sympathetic dystrophy) or with (CRPS II, causalgia) obvious nerve lesions. The clinical picture of CRPS consists of asymmetrical distal extremity pain, swelling, and autonomic (sympathetic) and motor symptoms. Changes in the peripheral and central somatosensory, autonomic and motor processing, and a pathologic interaction of sympathetic and afferent systems are discussed as underlying pathophysiologic mechanisms. Therapeutic strategies include pharmacologic pain relief, sympatholytic interventions, and rehabilitation.
