Background and Aim: The aim of the present study was to evaluate the effects of motion control shoes on knee joint co-contraction in overweight individuals with flat feet.
Material and Methods: 15 overweight females with navicular dropgreater than 10 mm were selected with availible sampling. Demographic charectrestics of participants include age: 26.8±2.5 years, height: 1.7±0.1 m, weight: 82.5±3.2 kg, and body mass index: 28.2±1.1 kg/m2. The present study was done during running with both control (Supernova control, Adidas) and motion control (Supernovacushion, Adidas) shoes. Electrical activity of selected muscles was recorded by electromyography system and then the co-contraction values were computed. Paired sample t-test was used for for statistical analysis.
Results: Finding demonstrated that during loading phase, the directed co-contraction of vastus medialis/lateralis while using of motion control shoes was greater than control shoes (P=0.035). Also, medio-lateral directed knee joint co-contraction while running with motion control shoe was greater than control shoe during push-off phase (P=0.020).
Conclusion: Motion control shoe improved directed co-contraction in overweight individuals with flat feet especially in the frontal plane that could modify imposed knee joint loads.
