Reflex sympathetic dystrophy (RSD) is a complex syndrome of pain, trophic changes, and vasomotor instability secondary to an abnormal hyperactive state of the sympathetic nervous system following injury to an extremity. Numerous theories have been proposed to explain the pathophysiology. None is universally accepted. The diagnosis of RSD is complicated because some patients improve without treatment, whereas others develop intractable symptoms even after the injury has healed. A delay in diagnosis and/or treatment for this syndrome can result in severe physical and psychological problems. Early recognition and prompt treatment, i.e., sympathetic blockade and physical therapy, provide the greatest opportunity for a successful outcome.
反射性交感神经营养不良（RSD）是一种复杂的综合征，表现为疼痛、营养改变和血管运动不稳定，继发于肢体受伤后交感神经系统异常的亢进状态。人们提出了许多理论来解释其病理生理学。但没有一种被普遍接受。RSD的诊断很复杂，因为一些患者未经治疗就好转了，而另一些患者即使在损伤愈合后仍会出现难以治疗的症状。该综合征诊断和/或治疗的延迟会导致严重的身体和心理问题。早期识别和及时治疗，即交感神经阻滞和物理治疗，为成功治疗提供了最大机会。
