The problem of severe chronic pain following spinal cord injury (SCI) has been well delineated for many years. However, progress has been slow in determining which treatment procedures work for which type of SCI pain in a particular individual at a particular time. Reasons for such slow progress include the low incidence and prevalence of SCI making large series of patients unavailable for trials in many centers. Lack of a widely accepted SCI pain classification scheme has also limited the comparability of similar interventions carried out by different investigators. Design limitations of many existing studies that can be remedied in future investigations are reviewed. Finally, discussion of two conceptual models of SCI pain is presented and an argument raised for the utility of both.
脊髓损伤（SCI）后严重慢性疼痛的问题多年来已得到充分描述。然而，在确定在特定时间针对特定个体的哪种脊髓损伤疼痛适用何种治疗程序方面，进展一直缓慢。进展缓慢的原因包括脊髓损伤的发病率和患病率较低，导致许多中心无法获得大量患者进行试验。缺乏广泛接受的脊髓损伤疼痛分类方案也限制了不同研究者进行的类似干预措施的可比性。本文回顾了许多现有研究中可在未来研究中加以纠正的设计局限性。最后，介绍了两种脊髓损伤疼痛的概念模型并提出二者均有用的观点。
