Changes in the trunk and lower limbs' sagittal movements may cause patellofemoral pain (PFP) because they influence the forces acting on this joint.
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.
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.
The PFP group exhibited less trunk flexion (SLS, = .006; SD, = .016) and greater forward knee displacement (SLS, = .001; SD, = .004) than the asymptomatic group; there was no significant difference in ankle angle (SLS, = .074; SD, = .278). Correlation analysis revealed that decreased trunk flexion was associated with increased forward knee displacement (SLS, = -0.439, = .000; SD, = -0.365, = .004) and ankle dorsiflexion (SLS, = -0.339, = .008; SD, = -0.356, = .005).
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.
躯干和下肢矢状面运动的变化可能会导致髌股疼痛（PFP），因为它们会影响作用于该关节的力。
比较有和没有PFP的女性在功能测试期间躯干和下肢的矢状面运动学，并验证矢状面躯干运动学是否与膝盖和脚踝的运动学相关。
共有30名患有PFP的女性和30名无症状女性进行了单腿深蹲（SLS）和下台阶（SD）测试，并由一台摄像机在矢状面进行拍摄。计算躯干倾斜角度、膝关节向前位移和踝关节角度。
与无症状组相比，PFP组表现出更少的躯干前屈（SLS，P = 0.006；SD，P = 0.016）和更大的膝关节向前位移（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）。相关性分析显示，躯干前屈减少与膝关节向前位移增加（SLS，r = -0.439，P = 0.000；SD，r = -0.365，P = 0.004）和踝关节背屈增加（SLS，r = -0.339，P = 0.008；SD，r = -0.356，P = 0.005）相关。
患有PFP的女性在单足活动期间在矢状面存在躯干和膝关节的运动学改变。此外，躯干和下肢的矢状面运动是相互依存的。
