Our objective was to compare the reliability and responsiveness of the original Steinbrocker's (OS), our modified Steinbrocker's (MS) and Larsen's (L) radiological scoring methods for detecting radiological change in psoriatic arthritis over time. Two sets of radiographs of the hands and feet at least 2 yr apart were selected from 68 patients. Films were randomly presented and scored independently by a rheumatologist (DDG) and a radiologist (DS), in a blinded fashion using all methods. The index of reliability was the intraclass coefficient (ICC) and the responsiveness was assessed using plots and regression analyses. All three radiological scoring methods have excellent interobserver and good intra-observer reliability. L and MS are equally responsive and superior to OS in detecting change in joint damage over time. Thus, the L or MS radiological scoring methods can be used to monitor disease progression in psoriatic arthritis.
我们的目的是比较原始的斯坦布罗克（OS）、我们改良的斯坦布罗克（MS）和拉森（L）放射学评分方法在检测银屑病关节炎随时间推移的放射学变化方面的可靠性和反应性。从68例患者中选取了两组间隔至少2年的手足部X光片。胶片随机呈现，由一名风湿病学家（DDG）和一名放射科医生（DS）采用所有方法以盲法独立评分。可靠性指标为组内相关系数（ICC），反应性通过绘图和回归分析进行评估。所有三种放射学评分方法均具有出色的观察者间可靠性和良好的观察者内可靠性。在检测随时间推移的关节损伤变化方面，L和MS具有同等的反应性且优于OS。因此，L或MS放射学评分方法可用于监测银屑病关节炎的疾病进展。
