Introduction: To understand the mechanism of patellofemoral pain syndrome, determination the sources of tibial rotation movement is essential. Axial tibial rotation can causes by proximal or distal factors. Mechanical energy and power flow have been useful tools for evaluating and identifying the movement strategies. The aim of this study was to evaluate the effect of anti-anterior pelvic tilt taping on the axial tibial power flow pattern and three dimensional kinematics of the hip joint
Methodology: 23 patients with patellofemoral pain syndrome (20–25 years) performed 5 running trials at speed of 3 ±0.2 m/s during two conditions (no- intervention and anti-anterior pelvic tilt taping). Video and force-plate data were collected simultaneously to calculate the joint angles and axial tibial power flow. All of patients had proximal cause of axial tibial rotation (negative power flow). Statistical analysis was done by McNemar and paired sample T test.
Results: An anti-anterior pelvic tilt taping significantly reduced peak hip adduction (p=0.011) and internal rotation angles (p = 0.001). No between conditions differences in sagittal plane hip angle were observed. The result of McNemar test showed that there were not any between conditions differences in power flow pattern.
Discussion: The results of this study indicated that the anti-anterior pelvic tilt taping lead to the hip joint kinematics become similar to healthy population. However, taping did not have any effect on power flow pattern that determine the sources of axial tibial rotation. The results suggested that the kinematics interventions do not able change the power flow pattern.
