Background and Aim: Genu varus is one of the most common lower extremity complications that affect a person's activity during daily activities and sports. The aim of this study was to investigate the effect of 8 weeks using knee braces on frequency of muscles in people with genu varus during walking.
Materials and Methods: The present study was a quasi-experimental. 30 male students with genu varus (20-30 years) were randomly divided into control and intervention groups. Corrective exercises were performed for 8 weeks using braces for the intervention group. Electrical activity of selected muscles was recorded by electromyography system. For statistical analysis, ANCOVA test was used at a significance level of 0.05.
Results: During loading phase, the results of the present study showed lower frequency content of biceps femoris muscle in experimental group compared with control group (P=0.041). Frequency content of other muscles did not demonstrate any significant difference between groups (P>0.05).
Conclusion: Due to the decrease in the frequency of biceps femoris muscle in experimental group than that control group, it can be stated that 8-week use of the brace can be effective in reducing the shock absorption imposed to the lower extremity.
