BACKGROUNDS
Many ankle injuries occur while participating in sports that require jumping and landing such as basketball, volleyball and soccer. Most recent studies have investigated dynamic postural stability of patients with chronic ankle instability after landing from a forward jump. The present study aimed to investigate the dynamic postural stability of the athletes who suffer from chronic ankle sprain while landing from a lateral jump.
METHODS
Twelve athletes with self-reported unilateral chronic ankle instability (4 females and 8 males) and 12 matched controls (3 females and 9 males) voluntarily participated in the study. Dynamic postural stability index and its directional indices were measured while performing lateral jump landing test.
RESULTS
No differences were found between athletes with and without chronic ankle instability during our landing protocol by means of the dynamic postural stability index and its directional indices. Findings showed that in each group, medial/lateral stability index is significantly higher than anterior/posterior and vertical stability indexes.
CONCLUSION
Findings showed that dynamic postural stability was not significantly different between the two groups. Future studies should examine chronic ankle instability patients with more severe disabilities and expose them to more challenging dynamic balance conditions to further explore postural stability.

背景
许多踝关节损伤发生在参与需要跳跃和落地的运动时，如篮球、排球和足球。最近的研究调查了慢性踝关节不稳定患者从向前跳跃落地后的动态姿势稳定性。本研究旨在调查患有慢性踝关节扭伤的运动员从侧向跳跃落地时的动态姿势稳定性。
方法
12名自我报告有单侧慢性踝关节不稳定的运动员（4名女性和8名男性）和12名匹配的对照组（3名女性和9名男性）自愿参与本研究。在进行侧向跳跃落地测试时测量动态姿势稳定性指数及其方向指数。
结果
通过动态姿势稳定性指数及其方向指数，在我们的落地方案中，有和没有慢性踝关节不稳定的运动员之间未发现差异。结果表明，在每组中，内侧/外侧稳定性指数显著高于前后和垂直稳定性指数。
结论
结果表明，两组之间的动态姿势稳定性没有显著差异。未来的研究应该检查残疾更严重的慢性踝关节不稳定患者，并让他们暴露在更具挑战性的动态平衡条件下，以进一步探索姿势稳定性。
