Abstract

Introduction and objectives

Given their known impact on function, anthropometrics and pain should be examined in knee osteoarthritis functional tests. To evaluate how anthropometric measures and pain influence the 30-s CST, 40m FPWT, and 11-step SCT in individuals with KOA.

Material and methods

This is a cross-sectional study with 142 participants included. We collected anthropometric data, then applied the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire, recorded pain and we administered the performance-based tests. Multiple linear regression models were used to assess the influence of clinical and demographic variables on each performance-based test. We performed the analyses in the R language (R version 4.3.2), adopting a significance level of 5%.

Results

Participants had a mean BMI of 29.1, mean pain 3.5, and mean WOMAC 47. Older age, higher BMI, and female sex were consistently associated with poorer performance. In the 40-meter Fast-Paced Walk Test, older age (β = 0.39, 95% CI [0.25, 0.53], p < 0.001) and higher BMI (β = 0.41, 95% CI [0.15, 0.66], p = 0.002) predicted slower performance, with men performing faster (β = −3.86, 95% CI [−6.36, −1.36], p = 0.003). Similar patterns were observed in the 30-s Chair Stand and 11-step Stair Climb tests, with worse WOMAC scores additionally associated with lower performance. Pain did not significantly affect any test.

Conclusion

Advanced age, being female, high BMI and low self-reported function negatively impacted performance-based tests.

膝关节骨关节炎的人体测量和疼痛相关因素与功能表现相关：一项横断面研究

介绍和目的考虑到已知的对功能的影响，人体测量学和疼痛应该在膝关节骨关节炎功能测试中进行检查。评估人体测量和疼痛对KOA患者30-s CST、40 - m FPWT和11步SCT的影响。材料与方法本研究为横断面研究，纳入142名受试者。我们收集了人体测量数据，然后应用了西安大略和麦克马斯特大学骨关节炎指数（WOMAC）问卷，记录了疼痛并进行了基于性能的测试。使用多元线性回归模型来评估临床和人口统计学变量对每个基于性能的测试的影响。我们使用R语言（R版本4.3.2）进行分析，采用5%的显著性水平。结果参与者的平均BMI为29.1，平均疼痛为3.5，平均WOMAC为47。年龄越大，身体质量指数越高，性别越女性，成绩越差。在40米快节奏步行测试中，年龄越大（β = 0.39, 95% CI [0.25, 0.53], p < 0.001）和BMI越高（β = 0.41, 95% CI [0.15, 0.66], p = 0.002）的受试者表现越慢，而男性表现越快（β = - 3.86, 95% CI [- 6.36, - 1.36], p = 0.003）。在30秒的椅子站立和11步爬楼梯测试中也观察到类似的模式，WOMAC得分越低，表现越差。疼痛对任何测试都没有显著影响。结论高龄、女性、高BMI和低自我报告功能对性能测试有负面影响。
