Abstract


Background: the supinated foot is one of the lower limb abnormalities that is associated with navicular drop and may be affected by leg muscles. The aim of this study was to investigate the effects of 8-week corrective exercises to improve static and dynamic balance of supinated foot.

Materials and methods: The current research is a quasi-experimental study, in which twenty 18-25 male subjects that all suffer supinated leg were chosen purposefully into two groups (10) of experimental and control. Before the training program of supinated legs of navicular drop test subjects, static balance and dynamic balance was measured with a force platform. The experimental group carried out exercises program for 8 weeks with a frequency of three times a week on the area of weak muscles and stretched legs, and the control group were doing their usual activities. After 8 weeks of corrective exercises, static and dynamic balance and supinated leg were measured again. To analyze the data, independent t-test for changes between the group and dependent t-test for within-group changes were used.

Findings: The results showed a significant increase in static balance (shifting the center of pressure, p = 0.011), dynamic balance (time to stabilization in the lateral direction, p = 0.008) as well as supinated leg (p = 0.00)between pre-test and post-test experimental group. However, no significant differences in dynamic balance in the anterior-posterior direction (p = 0.2) in the experimental group were observed. In the control group variables during the study period, no significant difference was observed.

Conclusion: Using corrective exercises presented in this study, the static and dynamic balance level and navicular drop could be improved, and supinated foot deformity was corrected.
