目的：确定膝关节骨性关节炎（OA）患者自我报告活动性测量的决定因素，并将自我报告测量与身体表现进行比较。设计：横断面，前瞻性。设置：运动性能实验室和人类活动性研究中心。参与者：54名膝关节内侧间室OA参与者的方便样本（32名女性，22名男性;年龄68.3+/-8.7岁;范围：50- 87岁）。3名参与者因X线片上存在外侧膝关节OA而被排除。干预措施：不适用。主要结果测量：通过使用西安大略麦克马斯特大学骨关节炎指数（WOMAC）和医学结果研究36项健康调查简表（SF-36）记录自我报告。性能指标包括六分钟步行试验（6 MWT），定时上升和去（TUG）测试，和一个标准化的爬楼梯任务（STR）。结果：逐步线性回归分析确定的模型，包括疼痛，股四头肌和腿筋力量，抑郁症，解释62%至73%的变异的WOMAC和SF-36的身体功能子量表的分数。这些自我报告的措施有中度相关（r范围，.46 -64）与性能措施（6 MWT，TUG，STR.结论：自我报告的措施是强烈相关的疼痛;物理性能措施是强烈相关的自我效能感。回归模型显示，自我报告评分反映了疼痛、膝关节力量和抑郁。自我报告和业绩计量之间的关系是适度的，这表明这些审查流动的不同方面。
Objectives: To identify the determinants of self-report mobility measures in people with knee osteoarthritis (OA) and to compare self-report measures with physical performance.Design: Cross-sectional, prospective.Setting: Motor performance laboratory and human mobility research center.Participants: A convenient sample of 54 participants with medial compartment knee OA (32 women, 22 men; age 68.3+/-8.7y; range, 50-87y). Three participants were excluded because of the presence of lateral knee OA on radiographs. Interventions: Not applicable.Main Outcome Measures: Self-reports were recorded by using the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Performance measures included the six-minute walk test (6MWT), Timed Up & Go (TUG) test, and a standardized stair-climbing task (STR).Results: Stepwise linear regression analysis identified models that included pain, quadriceps and hamstrings strength, and depression to explain 62% to 73% of the variance in scores on the physical functioning subscale of the WOMAC and the SF-36. These self-report measures had a moderate relation (r range,.46-64) with performance measures (6MWT, TUG, STR).Conclusions: Self-report measures were strongly related to pain; physical performance measures were strongly related to self-efficacy. Regression models showed that self-report scores reflect pain, knee strength, and depression. The relation between self-report and performance measures was moderate, suggesting that these examine different aspects of mobility.
