目的：研究放射学骨关节炎（罗阿）和当前膝关节疼痛对下肢身体功能、股四头肌力量、膝关节本体感觉和姿势sweet.Methods的相对影响：采用262析因设计，根据罗阿的存在或不存在，将142名45岁以上的社区受试者分为四个亚组（Kellgren & Lawrence. 2级）和膝关节疼痛（通过NHANES问题和100 mm视觉模拟量表评估）。最大等长收缩股四头肌，膝关节本体感觉敏锐度，静态姿势摇摆，和WOMAC指数（整体和功能分量表）进行了评估在所有subjects.Results：与正常人相比，报告的残疾是更大的所有其他亚组（p < 0.01）。罗阿和膝关节疼痛的受试者报告的残疾最大，仅膝关节疼痛的受试者比仅罗阿的受试者残疾更大。股四头肌无力各组与正常对照组比较有显著性差异（P < 0.01），但组间差异无显著性。有膝关节疼痛的受试者比没有膝关节疼痛的受试者有更大的摇摆面积（p < 0.05），但罗阿的存在与姿势摇摆的增加无关。groups.Conclusions：膝关节疼痛的存在与股四头肌力量，姿势摇摆和残疾相比，罗阿有负相关。然而，无痛罗阿的存在对相对股四头肌力量和报告的残疾有显著的负面影响。
Objective: To investigate the relative impact of radiographic osteoarthritis (ROA) and current knee pain on lower limb physical function, quadriceps strength, knee joint proprioception, and postural sway.Methods: Using a 262 factorial design, 142 community derived subjects aged over 45 were divided into four subgroups based on the presence or absence of ROA (Kellgren & Lawrence. grade 2) and knee pain (as assessed by NHANES questions and a 100 mm visual analogue scale). Maximum isometric contraction of the quadriceps, knee joint proprioceptive acuity, static postural sway, and WOMAC index (both whole and function subscale) were assessed in all subjects.Results: Compared with normal subjects, reported disability was greater for all other subgroups (p < 0.01). Subjects with both ROA and knee pain reported the greatest disability, and those with knee pain only had greater disability than those with ROA only. Quadriceps weakness was observed in all groups compared with normal subjects (p < 0.01), though they were no significant intergroup differences. Subjects with knee pain had a greater sway area than those without (p < 0.05) but the presence of ROA was not associated with increased postural sway. No differences in proprioceptive acuity were observed between groups.Conclusions: The presence of knee pain has a negative association with quadriceps strength, postural sway, and disability compared with ROA. However, the presence of pain-free ROA has a significant negative influence on relative quadriceps strength and reported disability.
