Introduction – Flat feet need to be treated with the proper exercises. The purpose of this study was to compare the effects of dynamic stretching exercise with strengthening exercise in participants with flat feet. Methods – Participants included 73 subjects (12-14 years of age) with variety of flat feet degree who were recruited from a footprint with Arch Index (AI) and then randomly assigned to a dynamic stretching or strengthening treatment group. There were 35 participants in dynamic stretching group and 38 participants in strengthening group. The dynamic stretching treatment consisted of standing hamstring calf stretch, half kneeling with adductor stretch, and iliotibial band stretch. The strengthening treatment consisted of short foot, heel raise, and squat exercise. The main outcome measures were assessed with Independent T test for dependent variables. Results – There is statistically a significant difference between pre and post measurement readings with time (p = 0.00) and between groups (p < 0.05) with respect to longitudinal medial arch after 15 times exercise programs. Analysis showed more favor to dynamic stretching group (mean change, 0.031; 95% confidence interval [CI]: 0.025, 0.036) rather than strengthening group (mean change, 0.021; 95% CI: 0.012, 0.029). Conclusion – Our results showed that dynamic stretching exercise programs was more effective in improving fallen longitudinal medial arch than strengthening exercise programs. These findings suggest that dynamic stretching exercise is a valid option for treatment of flat feet.
