Abstract

Fatigue could lead to excessive eversion and affect static balance. This study was aimed to find out the influence of foot posture and jumping fatiguing effect on static balance and muscle activity of lower limb muscles. Methods: 19 elementary school children aged 9 to 11 years took part in this study. Of these all children, 10 had normal foot and 9 had flatfoot which was classified by their foot posture. Foot posture was measured based on arch index of footprint by a foot scanner. Surface electromyography (EMG) activity was recorded from tibialis anterior, gastrocnemius medialis and peroneus longus muscles while participants were standing on one leg barefoot with opened eyes. Results: Normal foot had arch index 0.25±0.01 whereas flatfoot had 0.36±0.01. Statistical analysis showed that fatigue could influence static balance in flatfoot children (p < 0.05). Based on electromiographic data, there were no significant differences on median frequency of lower limb muscles between both groups. After fatigue, median frequency (MF) timing was significantly different (p < 0.05) on tibialis anterior and peroneus longus. MF timing showed earlier in flatfoot. Conclusion: Fatigue influenced static balance and tended to appear earlier on lower limb muscles in flatfoot children.
