We sought to determine whether foot posture and foot mobility were increased in individuals with patellofemoral pain syndrome compared with individuals in a control group.
A nested case-control design was used with two controls matched to each patient by sex and age (±1 year). Participants included 43 individuals with a history of unilateral or bilateral patellofemoral pain syndrome and 86 participants in a control group. Data collected included height, weight, and five different measures of foot height and width in weightbearing and nonweightbearing that have been previously shown to have high levels of reliability.
Individuals with patellofemoral pain syndrome were found to be four times more likely (odds ratio, 4.04; 95% confidence interval, 1.45-11.32) to have a larger-than-normal difference between nonweightbearing and weightbearing arch height compared with those in the control group. The mean values for difference in arch height and foot mobility magnitude were also statistically significant between the patient and control groups. Foot posture, as determined using the arch height ratio, was not significant between groups (odds ratio, 0.94; 95% confidence interval, 0.34-2.61).
Although foot posture may not be different between individuals with patellofemoral pain syndrome and controls, foot mobility assessed using difference in arch height and foot mobility magnitude is different between the two groups.
我们试图确定与对照组个体相比，髌股疼痛综合征患者的足部姿势和足部活动度是否增加。
采用巢式病例对照设计，为每位患者匹配两名按性别和年龄（±1岁）配对的对照。参与者包括有单侧或双侧髌股疼痛综合征病史的43名个体和86名对照组参与者。收集的数据包括身高、体重以及负重和非负重状态下足部高度和宽度的五种不同测量值，这些测量值先前已被证明具有高度可靠性。
与对照组相比，髌股疼痛综合征患者非负重和负重足弓高度差异大于正常的可能性高出四倍（优势比，4.04；95%置信区间，1.45 - 11.32）。患者组和对照组之间足弓高度差异和足部活动度大小的平均值也具有统计学意义。使用足弓高度比确定的足部姿势在两组之间无显著差异（优势比，0.94；95%置信区间，0.34 - 2.61）。
虽然髌股疼痛综合征患者与对照组个体之间的足部姿势可能没有差异，但使用足弓高度差异和足部活动度大小评估的足部活动度在两组之间是不同的。
