Introduction: This study aimed to investigate the influence of sports shoe aging on the frequency domain of selected lower limb muscles in healthy individuals and those with genu varus during walking.
Methods: This study is a clinical trial. Fifteen girls with genu varus and fifteen healthy individuals were volunteered to participate in this study. Data were collected under two specific test conditions, including walking in new and worn shoes. The long time of the shoes was six months. A surface electromyography system recorded muscular electrical activity. Two way ANOVA with Repeated measures test was used for data analysis. A significant level was set at P < 0.05.
Results: Finding demonstrated that shoe has a significant main effect on frequency content for vastus medialis during stance phase (P = 0.04), for tibialis anterior during loading response (P = 0.01) and push off aspects (P = 0.002), and for medial gastrocnemius during push-off phase (P = 0.003). Moreover, the group has a significant main effect on frequency content for tibialis anterior during stance (P = 0.04) and swing phases (P = 0.04).
Conclusions: It sounds that shoe aging changed the frequency content of lower limb muscles in both healthy and genu varus groups. In some cases, this altered frequency content could be associated with the occurrence of injury.
