This study compared the effectiveness of Leuko and Nessa Ankle braces in restricting inversion before, during and after exercise. Thirteen Australian Rules Footballers with a mean age of 23.7 years (range = 17-30), and who had no previous history of moderate to severe ankle sprains, were tested in this study. A pedal goniometer was used to measure active inversion with the ankle in 42 degrees plantarflexion. Measurements were taken prior to the application of the brace, immediately after the brace was applied, after 20 minutes of controlled activity involving running, side-stepping and jumping, and after a further 20 minutes of identical drills. A study design in which all subjects were required to wear each brace once was used. Analysis revealed no significant difference in ankle inversion between braces at any of the measurement times (p > 0.05). Both the Nessa and Leuko Ankle brace significantly restricted inversion immediately after the brace was applied, after 20 and 40 minutes of exercise. The results provide objective guidelines for the prescription of ankle braces in the prevention of ankle injuries during physical activity.
本研究比较了Leuko和Nessa踝关节护具在运动前、运动中和运动后限制内翻的效果。本研究测试了13名澳大利亚式橄榄球运动员，他们的平均年龄为23.7岁（范围 = 17 - 30岁），且既往无中度至重度踝关节扭伤史。使用踏板式测角仪在踝关节处于42度跖屈时测量主动内翻。在佩戴护具前、佩戴护具后立即、进行包括跑步、侧步和跳跃的20分钟控制活动后以及再进行20分钟相同训练后进行测量。采用了一种研究设计，要求所有受试者每种护具都佩戴一次。分析显示，在任何测量时间，两种护具之间的踝关节内翻均无显著差异（p > 0.05）。Nessa和Leuko踝关节护具在佩戴后、运动20分钟和40分钟后均显著限制了内翻。研究结果为在体育活动中预防踝关节损伤时踝关节护具的处方提供了客观指导。
