| Abstract |
| Introduction: Flat feet are one of the most common structural foot deformities characterized by the collapse of the medial longitudinal arch of the foot (Raj et al., 2023). This condition can lead to biomechanical abnormalities in the lower limb, including increased dynamic knee valgus angle (Sanchis et al.,2022). The aim of this study was to compare the effect of 8 weeks of Yoga asanas and Janda exercises on lower limb alignment (dynamic knee valgus angle) in girls with flat feet. Methods: 45 women with flat feet participated in this study. The samples were divided into 3 groups: Yoga asana exercises, corrective exercises with the Janda approach, and a control group. The intervention groups participated in the exercise programs for 8 weeks, three sessions per week. The first group performed Yoga asanas for 30 to 45 minutes and the second group performed Janda exercises for 60 minutes per session. The control group did not perform any exercises and continued their daily activities. Pre-test and post-test were performed to assess dynamic knee valgus in single-leg landing using 2D video analysis and marker placement on the ASIS, patella, and ankle (Harrington et al., 2010). Data were analyzed using SPSS version 21 and repeated-measures variance statistical test. Results: The findings showed that both the Yoga and Janda training groups had a significant reduction in dynamic knee valgus angle after 8 weeks, indicating the effectiveness of both programs. However, statistical analyses showed that the Yoga group had a greater and stronger effect on improving knee alignment than the Janda group. Conclusion: Yoga asanas strengthen deep stabilizing muscles, improve balance, and increase body awareness, all of which help correct dynamic knee valgus. Based on the results, both exercise programs are effective, but Yoga asanas are superior in improving lower limb alignment and are recommended for use in rehabilitation programs. |
