虽然有一个广泛的结果工具来评估有症状的踝关节炎患者，没有疾病特异性工具踝关节炎已被证明是可靠和有效的。本研究的目的是为踝关节骨关节炎的临床评估开发一种简单、可靠、有效的结果测量方法。我们修改了足部功能指数，一种用于评估类风湿性足部问题的基于视觉模拟的量表，以衡量患者的症状和踝关节骨关节炎引起的功能限制。对踝关节骨关节炎量表及其两个分量表（疼痛和残疾）进行重测信度、标准和结构效度测定。总体可靠性（r = 0.97; 95%置信区间[CI]，0.94-0.99）、疼痛子量表可靠性（r = 0.95; 95% CI，0.90-0.98）和残疾子量表可靠性（r = 0.94; 95% CI，0.88-0.97）均极佳。该仪器与WOMAC（骨关节炎的疾病特异性量表）和SF-36（一般健康调查）的标准有效性测试显示相关子量表的高度一致性。结构有效性使用的物理测量踝关节功能表现出灵敏度的仪器关节功能障碍的程度。从562名非患者（264名男性和298名女性）中获得了规范性数据。分析了性别、体重指数、关节炎的存在、与反应水平相关的骨折史和年龄的趋势。发现性别的一个小但统计学显著的主要影响，女性一贯报告更高的疼痛，残疾和总指数评分。还发现体重指数和关节炎与子量表和总指数评分的反应答案相关;然而，这些因素仅占变异的12%。踝关节骨关节炎量表是一个可靠和有效的自我评估工具，专门衡量病人的症状和残疾有关的踝关节炎。
Although there is a wide array of outcome tools for assessing patients with symptomatic ankle arthritis, no disease-specific instrument for ankle arthritis has been shown to be reliable and valid. The purpose of this study was to develop a simple, reliable, and validated outcome measure for the clinical assessment of ankle osteoarthritis. We modified the Foot Function Index, a visual analog-based scale used to assess rheumatoid foot problems, to measure patient symptoms and functional limitations stemming from osteoarthritis of the ankle joint. Test-retest reliability and criterion and construct validity were determined for the overall Ankle Osteoarthritis Scale and its two subscales (pain and disability). Overall reliability (r = 0.97; 95% confidence interval [CI], 0.94-0.99), pain subscale reliability (r = 0.95; 95% CI, 0.90-0.98), and disability subscale reliability (r = 0.94; 95% CI, 0.88-0.97) were excellent. Criterion validity testing of the instrument with the WOMAC (a disease-specific scale for osteoarthritis) and the SF-36 (a general health survey) showed a high degree of concordance for related subscales. Construct validity using a physical measure of ankle function demonstrated sensitivity of the instrument to the degree of joint dysfunction. Normative data were obtained from 562 individuals who were not patients (264 men and 298 women). The responses were analyzed for trends in gender, body mass index, presence of arthritis, history of fracture in relation to the response levels, and age. A small but statistically significant main effect for gender was found, with women consistently reporting higher pain, disability, and total index scores. Body mass index and arthritis were also found to correlate with response answers across the subscale and total index scores; however, these factors only accounted for 12% of the variation. The Ankle Osteoarthritis Scale is a reliable and valid self-assessment instrument that specifically measures patient symptoms and disabilities related to ankle arthritis.
