Introduction: Dynamic knee valgus, static and dynamic balance are contributing to knee injuries in military cadets. This study aimed to investigate the effect of the Stop-X injury prevention program on dynamic knee valgus, static and dynamic balance in military cadets with dynamic knee valgus deficiency.
Methods: The present study was quasi-experimental. At first 116 students were assessed and finally, 40 participants with dynamic valgus were recruited and they were randomly assigned to the intervention group (n=20) or control group (n=20). Drop-jump test, Bass Stick test and Y Balance test were used to measure dynamic knee valgus angle, static and dynamic balance at the baseline and the end of the study. After evaluating the variables in the pre-test, the intervention group used the Stop-X program as a warm-up for 8 weeks while the control group performed its routine warm-up during this time and finally they were re-evaluated. ANCOVA and paired-samples t-test were used to evaluate changes.
Results: The results showed that there was a significant reduction in knee valgus angle (P=0.001) and there were significant enhancements in static (P=0.001) and dynamic balance (P=0.001) in the intervention group in comparison with the control group in the post-test. Moreover, the results obtained in the intervention group in post-test in comparison with pre-test showed that there was a significant reduction in knee valgus angle (P=0.001) and there were significant enhancements in static (P=0.001) and dynamic balance (P=0.001) but there were no significant differences in the control group (P>0.05).
Conclusion: This study demonstrated that the Stop-X injury prevention program was effective in reducing dynamic knee valgus angle and improving static balance time and dynamic balance in military cadets. Thus, this program can reduce the risk of knee injuries in military cadets.
