EVALUATION OF THE EFFECT OF ELASTIC BANDAGE ON THE ANKLE BASKETBALL PLAYERS WITH AND WITHOUT CHRONIC INSTABILITY

ABSTRACT Introduction: Basketball is a sport that requires good motor coordination as well as intense and multidirectional movements. Chronic ankle instability affects about 40% of patients who have sustained a sprain injury. In order to minimize the effects of this dysfunction, functional elastic tape has been widely used due to its mechanical properties, having some positive effects on athletes’ functional performance. Objective: To evaluate the effect of elastic tapes on the ankles of basketball players with and without chronic instability. Method: Thirteen athletes from a varsity basketball team of both sexes, aged between 18 and 30 years (23.2 ± 3.2 years), who had been playing the sport for at least one year and trained at least twice a week. The subjects were assessed using the anterior drawer test for the presence or absence of chronic ankle instability and in three different situations: placebo, elastic tape and control, and the order of use of the implements was randomly determined, using the Star Excursion Balance Test (SEBT) to assess the ankle stability of these athletes. Results: Among the eight directions proposed in the SEBT, there was statistical significance in the difference in three directions for the placebo method in comparison to elastic taping and control. There was no statistical significance in the difference in four directions between the assessments, and there was no statistical significance in the difference in all directions between the control and elastic tapes. Conclusion: It can be inferred from the study that elastic taping does not have positive effects on joint stability in athletes with and without chronic instability, taking into account their functionality.

摘要
引言：篮球是一项对运动协调能力要求较高，且需进行高强度多方向移动的体育运动。慢性踝关节不稳（chronic ankle instability）在既往发生过踝关节扭伤的人群中占比约40%。为尽可能减轻该功能障碍带来的不良影响，功能性弹性贴布因其独特的机械特性被广泛应用，且对运动员的运动功能表现具有一定积极作用。
研究目的：评估弹性贴布对伴或不伴慢性踝关节不稳的篮球运动员踝关节的干预效果。
研究方法：招募某高校篮球队的13名男女运动员，年龄介于18至30岁（23.2±3.2岁），均具备至少1年篮球运动经历且每周至少开展2次训练。采用前抽屉试验（anterior drawer test）评估受试者是否存在慢性踝关节不稳，并设置三种测试情境：安慰剂贴布、弹性贴布及空白对照，测试器具的使用顺序采用随机分配方式；同时通过星型伸展平衡测试（Star Excursion Balance Test, SEBT）评估受试者的踝关节稳定性。
研究结果：在SEBT设定的8个测试方向中，安慰剂贴布组与弹性贴布组、空白对照组相比，有3个方向的组间差异具有统计学意义。不同测试情境间的4个方向差异无统计学意义；且空白对照组与弹性贴布组在所有测试方向上的差异均无统计学意义。
研究结论：结合运动员的踝关节功能表现来看，可推断弹性贴布对伴或不伴慢性踝关节不稳的运动员的关节稳定性无积极作用。本研究证据等级为I级；属于高质量随机对照试验，其研究结果要么存在统计学差异，要么虽无统计学差异但置信区间较窄。
