Complex regional pain syndrome (CRPS) I, formerly known as reflex sympathetic dystrophy (RSD), is a painful neuropathic condition that most commonly affects a traumatized extremity. It is characterized by pain that is out of proportion to the original injury, has a distal predominance, and is not attributable to a specific peripheral nerve injury. The name RSD has been changed to CRPS I reflecting the fact that although sympathetic dysfunction can maintain the painful state, it is not the essential pathophysiologic lesion. Successful treatment hinges on early recognition of suspected cases, prompt referral to pain specialists, and ultimately pain control and return of limb function. Treatments range from noninvasive medications and therapies to sympathetic ganglion blockade and sympathectomy. The sports medicine physician is in an ideal position to recognize CRPS I in its earliest stages postinjury, and is advised to make prompt referral to a pain specialist when suspected.
复杂性区域疼痛综合征I型（CRPS I），以前称为反射性交感神经营养不良（RSD），是一种疼痛性神经病变，最常影响受伤的肢体。其特征是疼痛与原始损伤不成比例，以远端为主，且不能归因于特定的周围神经损伤。RSD这个名称已改为CRPS I，这反映出尽管交感神经功能障碍可维持疼痛状态，但它并非基本的病理生理病变。成功的治疗取决于对疑似病例的早期识别、及时转诊至疼痛专科医生，最终实现疼痛控制和肢体功能恢复。治疗方法从非侵入性药物和疗法到交感神经节阻滞及交感神经切除术不等。运动医学医生处于在损伤后最早阶段识别CRPS I的理想位置，建议在怀疑时及时转诊至疼痛专科医生。
