PURPOSE
Ankle sprain is one of the most common injuries among athletes and instability and injury to this joint is responsible for long time loss of physical and recreational activity. Also, it can impose high costs to sport teams. Prevention of this injury is an important concern of practice and rehabilitation. One way of reducing the possibility of ankle joint injury is using an ankle orthosis. The present study aimed at inspecting the effects of two ankle orthoses on dynamic and semi-dynamic postural stability in athletes with chronic ankle instability (CAI).
METHODS
Twenty basketball players with CAI and fifteen non-injured athletes volunteered to participate in this study. Biodex Balance System was used to assess the participants' postural stability in bilateral position at level 8 and level 2. Repeated measures analysis of variance (ANOVA) was performed in order to examine the effects of ankle orthoses. Statistical significance level was determined at P< 0.05.
RESULTS
Statistical analyses revealed the significant effect of ankle supports on dynamic and semi-dynamic postural stability in the two groups and results indicated there wasn't significant difference between groups.
CONCLUSIONS
According to our results the orthoses improved both dynamic and semi-dynamic postural stability. Therefore, orthoses can prevent injury and its reoccurrence.
目的
踝关节扭伤是运动员中最常见的损伤之一，该关节的不稳定和损伤会导致长时间丧失体育活动和娱乐活动能力。此外，它还会给运动队带来高昂成本。预防这种损伤是实践和康复中的一个重要关注点。减少踝关节损伤可能性的一种方法是使用踝关节矫形器。本研究旨在考察两种踝关节矫形器对慢性踝关节不稳定（CAI）运动员动态和半动态姿势稳定性的影响。
方法
20名患有CAI的篮球运动员和15名未受伤的运动员自愿参与本研究。使用Biodex平衡系统评估参与者在8级和2级双侧位置的姿势稳定性。进行重复测量方差分析（ANOVA）以检验踝关节矫形器的效果。统计学显著性水平设定为P < 0.05。
结果
统计分析显示踝关节支撑对两组的动态和半动态姿势稳定性有显著影响，结果表明两组之间没有显著差异。
结论
根据我们的结果，矫形器改善了动态和半动态姿势稳定性。因此，矫形器可以预防损伤及其复发。
