Abstract
Purpose:
Functional ankle instability is one of the most common residual and debilitating symptoms of acute ankle sprain which usually makes the athlete to be out of training program for a while. This study aimed to investigate the effect of four weeks core stability training on some lower extremity kinematics variables in athletes with functional ankle instability during a single-leg drop landing task
Method:
In this semi-experimental research, study population included 24 athletes with functional ankle which were divided into two experimental (n=12), and control (n=12) groups. To assess the drop-landing task with functional instability foot,240 Hz frequency motion analysis system was used. The recorded movements were analyzed by Nexus 2.6 version. The hip, knee, and ankle angles were extracted on the sagittal plane, and finally, repeated measure ANOVA and Bonferroni posthoc were used to compare two groups (p≤0.05).
Result:
There was no significant difference in the angle of the ankle after four weeks training (p≥0.05). However, in the angle of the hip and knee were found a significant difference from pretest to post-test (p≤0.05)
Conclusion:
The results indicated that four weeks core stability training improves kinematics of landing in athletes with functional ankle instability, and it seems that these exercises can be a method of preventing re-injury of the ankle.
