Functional ankle instability, orthoses, and passive resistive torque tolerated have not been researched. The purpose of the study was to evaluate the passive resistance torque exerted by a flexible and semirigid orthosis for individuals with chronic instability. Twenty-two subjects were evaluated on the passive ankle resistance unit during unbraced, flexible, and semirigid brace conditions. Data from the final three trials for each condition were analyzed using a multiple analysis of variance with repeated measures for resistive torque and inversion range of motion. The semirigid and flexible braces tolerated significantly greater torque forces and less inversion range than the unbraced condition (P < 0.000). External orthotic support, in particular that of a semirigid orthosis, may be beneficial toward reducing injury or be an effective prophylactic for the healthy population.
功能性踝关节不稳、矫形器以及可耐受的被动阻力矩尚未得到研究。本研究的目的是评估柔性和半刚性矫形器对慢性踝关节不稳患者施加的被动阻力矩。22名受试者在不佩戴矫形器、佩戴柔性矫形器和半刚性矫形器的情况下，在被动踝关节阻力装置上接受评估。使用重复测量的多元方差分析对每种情况的最后三次试验数据进行分析，分析指标为阻力矩和内翻活动范围。与不佩戴矫形器的情况相比，半刚性和柔性矫形器可耐受更大的扭矩力，内翻范围更小（P < 0.000）。外部矫形器支持，尤其是半刚性矫形器，可能有助于减少损伤，或者对健康人群是一种有效的预防措施。
