We propose an analog restless legs syndrome (RLS) rating scale (ARLS) to assess RLS severity. ARLS has three components: overall perceived severity of symptoms, the severity of urge to move and the degree to which symptoms improve with movement, each scored from 0 to 100. ARLS is relatively convenient, easy to administer in clinics and can be rapidly assessed. Our goal was to compare the novel ARLS with the well-known International RLS Study Group scale (IRLS) to assess the efficacy of the ARLS. ARLS and IRLS were administered on 93 occasions. Perceived severity of the disease measured with ARLS positively correlated with the normalized IRLS score (correlation coefficient 0.6; slope 1.2; p<0.0001). Improvement in symptoms after movement inversely correlated with the disease burden as measured with normalized IRLS score (slope -0.94; correlation coefficient 0.4; p=0.0001). For both low and high IRLS scores, the urge to move measured with ARLS saturated, suggesting a non-linear, multifactorial relationship between the perception of RLS severity and the urge to move. In conclusion, individual components of the ARLS correlated well with total IRLS score. We emphasize that the ARLS is a simple RLS rating tool that can be used in clinical settings.
我们提出了一种模拟不宁腿综合征（RLS）评分量表（ARLS）来评估 RLS 的严重程度。ARLS 有三个组成部分：症状的总体感知严重程度、移动的强烈冲动程度以及症状随运动改善的程度，每个部分的评分范围为 0 到 100。ARLS 相对方便，易于在诊所进行管理，并且可以快速评估。我们的目标是将新型 ARLS 与著名的国际 RLS 研究组量表（IRLS）进行比较，以评估 ARLS 的疗效。在 93 次就诊中同时使用了 ARLS 和 IRLS。用 ARLS 测量的疾病严重程度与标准化的 IRLS 评分呈正相关（相关系数 0.6；斜率 1.2；p<0.0001）。运动后症状的改善与标准化 IRLS 评分所衡量的疾病负担呈负相关（斜率-0.94；相关系数 0.4；p=0.0001）。对于低和高 IRLS 评分，用 ARLS 测量的移动冲动趋于饱和，表明 RLS 严重程度的感知与移动冲动之间存在非线性、多因素关系。总之，ARLS 的各个组成部分与总 IRLS 评分相关性良好。我们强调，ARLS 是一种简单的 RLS 评分工具，可用于临床环境。
