Abstract: (2392 Views)
Background & Aims: Increasing the angle of the valgus by making changes to the lower limbs can cause changes in the center of gravity of the body relative to the level of reliance and limit balance control. The aim of this study was to investigate the effects of a corrective exercise course using an elastic band on the frequency spectrum of ground reaction forces in young boys with genu valgum during running.
Materials & Methods: The present study was a clinical trial. 24 male students with genu valgum (20-30 years) were randomly assigned to control and experimental groups. Corrective exercises were performed for 8 weeks using an elastic band for the experimental group. Ground reaction forces were recorded by the Bertec force plate. For statistical analysis, SPSS V21 software and analysis of repeated measure ANOVA were used at a significance level of 0.05.
Results: The results of the present study showed a decrease in the median frequency in the anterior-posterior direction of the experimental group during the post-test compared to the pre-test (p = 0.025; d = 3.921). Also, in the experimental group, the frequency band component showed a significant decrease in anterior-posterior direction during the post-test compared to pre-test (p = 0.028; d = 3.843).
Conclusion: Due to the reduction in median frequency, it can be concluded that the corrective exercises used were able to reduce the incoming forces in the anterior-posterior direction. With the reduction of the frequency band during corrective exercises, the participation and activity of motor performance have also decreased.
