The Effect of Corrective Exercises Using Thera-Band on Components of Ground Reaction Force in Boy Students with Genu Valgum during Running: A Clinical Trial Study

Background and Objectives: Knee joint, like other joints in the body, is affected by defects, injuries and diseases. Genu valgum is one of the most common lower limb complications. The purpose of the present study was to determine the effects of corrective exercises using Thera-Band on components of ground reaction force in boy students with genu valgum during running. Materials and Methods: The present study was a clinical trial. 24 male students (20-30 years old) were randomly divided into control and experimental groups. The present study was conducted at University of Mohaghegh Ardabili Health and Wellness Center in 2019. Corrective exercises were performed for 8 weeks using Thera-band for the experimental group. The control group did not receive any treatment intervention during this period. The ground reaction forces were recorded by a force plate. Data were analyzed using repeated measures ANOVA. Results: The results of this study showed a significant difference in the time to peak in the vertical direction during the push off phase of the experimental group (5.17%) (p=0.030, d=0.589). In the experimental group, the other components of ground reaction forces did not demonstrate any significant effect during post-test than that in the pre-test (p>0.05). Conclusion: The selected corrective exercises using the Thera-band were able to increase the time to peak of the vertical force during the push off phase during the post-test compared to the pre-test. This increase was probably due to the longer contact of foot with the surface, which reduces the amount of force applied to the foot.
