BACKGROUND: Patellofemoral pain (PFP) is the most common running overuse injury. Excessive rearfoot eversion is commonly considered as a PFP risk factor and the relationship between ankle-foot complex movement and lower limb may be involved with this dysfunction. The purpose of this study was to evaluate the correlation between rearfoot eversion with tibia and femur kinematics in frontal and transverse planes during running in individuals with and without PFP. The secondary purpose was to compare the lower limb kinematics between runners with and without PFP. METHODS: Fifty-four recreational runners were divided into 2 groups: healthy runners (CG, n = 27) and runners with patellofemoral pain (PFPG, n = 27). Kinematics during running were assessed using three-dimensional motion analysis system. Pearson's correlation coefficients (r) were calculated to establish the correlation of rearfoot eversion with tibial and femur movements. FINDINGS: Greater peak rearfoot eversion was correlated with greater peak femur adduction in PFP runners. Greater peak rearfoot eversion was correlated with greater peak tibial internal rotation and tibial adduction in the PFPG and CG. Additionally, greater peak rearfoot eversion was correlated with greater tibial internal rotation range of motion in the PFPG and CG. No significant differences were found between the PFPG and CG for all kinematics variables. INTERPRETATION: Correlation between greater rearfoot eversion and greater peak hip adduction in the PFPG might be related to PFP persistence in runners with excessive rearfoot eversion, and indicates that treatment strategies aimed at controlling the movement of the rearfoot could help modify the symptoms.
