Abstract: (2225 Views)
Purpose: This study aimed to compare the impact of core stability and dynamic neuromuscular stabilization (DNS) training on knee valgus and motor function in 11- to 14-year-old students.
Methods: This study used a quasi-experimental design. Therefore, 60 female students from Tehran Province, Iran (mean age, 11.5 years) were selected as participants in this study and were randomly divided into three groups: core stability training, DNS training, and control. Knee valgus and movement function were measured using the Q angle and the functional movement screening (FMS) before and after the intervention. The participants in the experimental groups performed exercises for 6 weeks, with three sessions per week, each lasting 60 minutes. One-way analysis of variance and the least significant difference post hoc test were utilized to compare the groups, while the paired t-test was employed to assess within-group effects.
Results: The present study demonstrated a significant difference between the FMS test scores and knee valgus angle in the two experimental groups (DNS and core stability exercises) and the control group. However, no significant difference was observed in scores between the two experimental groups.
Conclusion: Overall, both DNS and core stability training significantly improve FMS test scores and decrease the knee valgus angle.
