Abstract
Background. Patellofemoral pain (PFP) is the most common overuse running injury in the knee joint (7.4 - 15.6%) that affected by osteoarthritis (OA). Individuals with OA showed less joint power in their affected knee which result reductions in the energy exerted by the leg and the plantar flexion power of the ankle joint during toe off. No evidence has shown if the use of appropriate foot orthoses could change knee joint power.
Aim. The purpose of this study was to investigate the acute effect of distal treatment modality on knee mechanical work in women with patellofemoral pain syndrome during running.
Methods. Ten females with PFPS were participated in this study. Participants were excluded from the study if they had 1) knee pain from an acute injury or from other disorders; 2) history of patellar dislocation; 3) previous knee surgeries within the past 12 months. Kinematic and kinetic data were recorded in both barefoot and with pronation control shoes conditions (ASISC Cayano 21) using six cameras (Basler 200 Hz) and a force plate (1000 Hz Kistler), respectively. Paired t-test was used to analyze the data at a significant level (p<0.05).
Results. Findings showed that the motion control shoe could decrease the mechanical work at the knee joint in the sagittal plane (p=0.004) while no significant effects were observed in the frontal (p >0.05) and horizontal (p >0.05) planes.
Conclusion. Generally, the amount of energy absorption at the knee could be decreased by use of motion control shoes during stance phase of running.
