客观的。本研究的目的是在患有慢性踝关节不稳定的人群中测试 10 种不同的踝关节支架在被动和快速诱导负载条件下的稳定性，以便为选择或推荐适合特定需求的适当模型提供客观信息。此外，还评估了被动和快速诱导反转稳定效果测试之间的关系，以确定在快速诱导条件下是否反映了支架的被动支撑特性。设计。使用了具有重复测量设计的体内实验研究。背景。踝关节支架通常用于治疗、康复和预防踝关节损伤。存在多种产品，但可用于帮助临床医生、物理治疗师和教练以及消费者根据客观信息选择支具的信息很少。此外，缺乏研究提供使用不同踝关节支架时被动和快速诱导踝关节运动的数据。方法。二十四名患有慢性踝关节不稳定的受试者参加了该项目。在定制的固定装置中进行被动踝关节运动范围测量，并在倾斜平台上引发模拟内翻扭伤。结果。与无支架条件相比，测试的支架显着限制了被动和快速诱导倒转的运动范围，并且揭示了支架之间的显着差异。发现被动和快速诱导反演测试结果之间存在密切关系。结论。被动和快速诱导的稳定性测试为描述不同踝关节支架的特性提供了客观信息的基础。被动和快速诱导反演的综合结果以及结果之间的相关性表明，在快速诱导条件下，支撑的被动支撑特性得以体现，但限制量减少。因此，仅根据被动支撑特性推荐用于动态环境下的应用时应谨慎。
Objective. The aim of the present investigation was to test the stability of 10 different ankle braces under passive and rapidly induced loading conditions in a population suffering from chronic ankle instability in order to provide objective information to choose or recommend an appropriate model for specific needs. In addition, the relationship between passive and rapidly induced testing of the stabilizing effect against inversion was evaluated to identify if passive Support characteristics of braces are reflected under rapidly induced conditions.Design. An experimental in vivo study with a repeated-measures design was used.Background. Ankle braces are commonly used for treatment, rehabilitation, and prevention of ankle injuries. A variety of products exists but there is few information available to assist clinicians, physiotherapists and coaches as well as consumers in choosing a brace on a basis of objective information. Furthermore, there is a lack of studies that provide data for both passively and rapidly induced movement of the ankle joint when using different ankle braces.Methods. Twenty-four subjects with chronic ankle instability participated in the project. Passive ankle range of motion measurements were performed in a custom-built fixture and simulated inversion sprains were elicited on a tilting platform.Results. The tested braces restrict range of motion significantly compared to the no-brace condition for both the passively and rapidly induced inversion and marked differences between braces were revealed. A close relationship between passive and rapidly induced test results for inversion was found.Conclusions. Passive as well as rapidly induced stability tests provide a basis of objective information to describe the characteristics of different ankle braces. Combined results of passive and rapidly induced inversion as well as correlation between results demonstrate that passive support characteristics of braces are reflected under rapidly induced conditions but the amount of restriction is reduced. Therefore, caution should be taken when recommending braces for applications under dynamic circumstances only on the basis of passive support characteristics.
