The purpose of this study was to examine the kinematic and kinetic parameters of the gait of patients with anterior knee pain. Fifteen symptomatic patients and 15 female control subjects were asked to perform 10 barefoot walks along a 10-m walkway. Ground reaction force data were collected using a force platform. Rearfoot motion data were collected using a video kinematic analysis system. The results showed that the controls exerted a significantly higher lateral force compared to patients. There was also a significant difference between controls and patients in the amount of time taken to maximum lateral force and in the time taken to achieve maximum angle between the axis of the calcaneus and axis of the tendo achilles. These results indicate that extended time to maximum lateral force rather than excessive lateral force is a discriminating factor in the gait of female patients with anterior knee pain who have a low recreational status. This contradicts previous studies using running analysis on athletes with this condition and suggests that in terms of diagnosis and treatment, care must be taken when comparing results from groups of different recreational status.
本研究的目的是检查前膝疼痛患者步态的运动学和动力学参数。15名有症状的患者和15名女性对照受试者被要求沿着10米长的通道进行10次赤脚行走。使用测力平台收集地面反作用力数据。使用视频运动分析系统收集后足运动数据。结果表明，与患者相比，对照组施加的侧向力明显更高。在达到最大侧向力所需的时间以及跟骨轴线与跟腱轴线之间达到最大角度所需的时间方面，对照组和患者之间也存在显著差异。这些结果表明，达到最大侧向力的时间延长而非侧向力过大是娱乐活动水平较低的前膝疼痛女性患者步态的一个鉴别因素。这与之前对患有这种疾病的运动员进行跑步分析的研究结果相矛盾，并表明在诊断和治疗方面，比较不同娱乐活动水平组的结果时必须谨慎。
