Abstract

Background: Changes in the trunk and lower limbs' sagittal movements may cause patellofemoral pain (PFP) because they influence the forces acting on this joint.

Objectives: To compare trunk and lower limb sagittal kinematics between women with and without PFP during functional tests and to verify whether sagittal trunk kinematics are correlated with those of the knees and ankles.

Methods: A total of 30 women with PFP and 30 asymptomatic women performed single-leg squat (SLS) and step-down (SD) tests and were filmed by a camera in the sagittal plane. The trunk inclination angle, forward knee displacement, and ankle angle were calculated.

Results: The PFP group exhibited less trunk flexion (SLS, p = .006; SD, p = .016) and greater forward knee displacement (SLS, p = .001; SD, p = .004) than the asymptomatic group; there was no significant difference in ankle angle (SLS, p = .074; SD, p = .278). Correlation analysis revealed that decreased trunk flexion was associated with increased forward knee displacement (SLS, r = -0.439, p = .000; SD, r = -0.365, p = .004) and ankle dorsiflexion (SLS, r = -0.339, p = .008; SD, r = -0.356, p = .005).

Conclusion: Women with PFP present kinematic alterations of the trunk and knee in the sagittal plane during unipodal activities. Furthermore, the trunk and lower limb sagittal movements were interdependent.

患有髌骨股骨痛的女性在进行单腿深蹲和下蹲任务时，躯干和下肢矢状运动会发生变化。

背景：躯干和下肢矢状运动的变化可能会导致髌骨股骨痛（PFP），因为它们会影响作用在该关节上的力：比较患有和未患有髌骨股骨痛的女性在功能测试中的躯干和下肢矢状运动学，并验证躯干矢状运动学是否与膝关节和踝关节的矢状运动学相关：共有30名患有PFP的女性和30名无症状的女性进行了单腿深蹲（SLS）和下台阶（SD）测试，并由摄像机在矢状面上进行拍摄。结果显示，PFP 组的躯干屈曲度较小，膝关节向前位移和踝关节角度较大：与无症状组相比，PFP 组的躯干屈曲度较小（SLS，p = 0.006；SD，p = 0.016），膝关节前移量较大（SLS，p = 0.001；SD，p = 0.004）；踝关节角度无显著差异（SLS，p = 0.074；SD，p = 0.278）。相关分析显示，躯干屈曲减少与膝关节前移增加有关（SLS，r = -0.439，p = .000；SD，r = -0.365，p = .004），与踝关节背屈有关（SLS，r = -0.339，p = .008；SD，r = -0.356，p = .005）：结论：患有 PFP 的女性在进行单足活动时，躯干和膝关节在矢状面上会出现运动学改变。此外，躯干和下肢矢状面运动是相互依存的。

期刊介绍： The aim of Physiotherapy Theory and Practice is to provide an international, peer-reviewed forum for the publication, dissemination, and discussion of recent developments and current research in physiotherapy/physical therapy. The journal accepts original quantitative and qualitative research reports, theoretical papers, systematic literature reviews, clinical case reports, and technical clinical notes. Physiotherapy Theory and Practice; promotes post-basic education through reports, reviews, and updates on all aspects of physiotherapy and specialties relating to clinical physiotherapy.
