Effects of Corrective Exercise Protocol Utilizing A TheraBand on Muscle Activity During Running in Individuals With Genu Valgum

Abstract

ackground and Aim: Genu Valgum is one of the most common lower limb malalignments that affects people's performance. The purpose of the present study was to investigate the effects of a corrective exercise protocol using a Theraband on muscle activity in individuals with genu valgum during running. Materials and Methods: The present study was a semi-experimental and laboratory study. 24 male students (20-30 years old) were randomly divided into control and experimental groups. Corrective exercises were performed for 8 weeks using Theraband on the experimental group. The electrical activity of selected muscles was recorded by electromyography system Statistical analysis was performed using repeated measures ANOVA test at the significant level of 0.05. Results: The results of the present study showed a significant decrease in biceps femoris muscular activity during stance phase of running by 69.98% in post-test compared to the pre-test (d=1.88, P=0.002). Also, the findings of the study showed a significant decrease in the electrical activity of the semitendinosus muscle during the post-test compared to the pre-test by 33.77% (d=0.86, P=0.024). The electrical activity of other muscles did not show any significant difference during post-test compared to pre-test (P>0.05). Conclusion: Decreased of biceps femoris muscle activity in individuals with genu valgus indicates a positive effect of rehabilitation using Theraband, and improving of performance in their daily activities.
