Abstract

Objectives

To compare the effects of the KISS ankle brace, Aircast ankle brace, and no brace condition, on functional performance measures and perceptions of stability, confidence and reassurance in people with and without chronic ankle instability.

Design

Randomised double-blinded cross-over trial.

Method

A total of 42 participants (21 uninjured and 21 with chronic ankle instability) were recruited from the general population and completed a series of functional performance tests, including side hop (seconds), Star excursion balance test reach distance, triple hop for distance (centimetres), modified T-agility test (seconds), standing and maximum vertical jump reach (centimetres), while wearing two ankle brace conditions and no brace (control). Results were recorded and analysed by a blinded investigator.

Results

There was no significant difference between conditions for average time on the side hop test (F(2,122) = 0.04, P = 0.96); best reach distance on SEBT in anterior (F (2,122) = 0.04, P = 0.96), postero-medial (F(2,122) = 0.08, P = 0.93) and postero-lateral (F(2,122) = 0.08, P = 0.92) directions; best distance performed on the triple hop (F(2,122) = 0.03, P = 0.97); best standing vertical jump performance (F(2,110) = 0.04, P = 0.97); best maximum vertical jump performance (F(2,110) = 0.01, P = 0.99); or best time for the modified T-agility run (F(2,122) = 1.61, P = 0.21).

Conclusions

Practitioners can be assured that functional and balance performances will not be impacted by wearing an ankle brace.

踝关节护具会影响功能表现吗？随机双盲交叉试验

目标比较 KISS 护踝、Aircast 护踝和无护踝对慢性踝关节不稳定患者和非慢性踝关节不稳定患者的功能表现测量以及稳定性、自信心和安心感的影响。方法从普通人群中招募了 42 名参与者（21 名未受伤者和 21 名慢性踝关节不稳定患者），在佩戴两种踝部支撑条件和不佩戴踝部支撑条件（对照组）的情况下，完成一系列功能表现测试，包括侧跳（秒）、星形偏移平衡测试到达距离、三跳距离（厘米）、改良 T 型敏捷性测试（秒）、站立和最大垂直跳跃到达距离（厘米）。结果在侧跳测试的平均时间（F(2,122) = 0.04，P = 0.96）；SEBT 在前方（F(2,122) = 0.04，P = 0.96）、后内侧（F(2,122) = 0.08，P = 0.93）和后外侧（F(2,122) = 0.08，P = 0.92）；三周跳的最佳距离（F（2，122）= 0.03，P = 0.97）；立定纵跳的最佳成绩（F（2，110）= 0.04，P = 0.97）；最大纵跳的最佳成绩（F（2，110）= 0.结论练习者可以放心，佩戴护踝不会影响功能和平衡表现。
