Purpose.
To explore the changes in knee sagittal angle and moment and patellofemoral joint (PFJ) force and stress before and after 12-week gait retraining.
Methods.
A total of 30 healthy male recreational runners were randomized into a control group (n=15) who ran in their original strike pattern using minimalist shoes or experimental group (n=15) who ran in a forefoot strike pattern using minimalist shoes during the 12-week gait retraining.
The kinematic and kinetic data of the dominant leg of the participants during the 12 km/h running were collected by 3D motion capture systems and 3D force platforms.
Besides, the biomechanical property of the PFJ was calculated on the basis of the joint force model and the regression equation of the contact area.
Results.
After the 12-week gait retraining, 78% of the rearfoot strikers turned into forefoot strikers.
Peak knee extension moment and peak PFJ stress decreased by 13.8% and 13.3% without altering the running speed, respectively.
Meanwhile, no changes in maximum knee flexion angle/extension moment and PFJ force/stress were observed for the control group.
Conclusion.
The 12-week gait retraining effectively reduced the PFJ stress, thereby providing a potential means of reducing the risk of patellofemoral pain syndrome while running.
