The ankle joints of 14 healthy volunteers and 16 patients with unstable ankle joints were tested for their functional and proprioceptive capabilities. All of them were active athletes. Three tests were used: the single-leg stance test, the single-leg jumping course test, and the angle-reproduction test. The influence of three stabilization devices--the lace-on brace (Mikros), the stirrup brace (Aircast), and taping--on the proprioceptivity of stable and unstable ankle joints was evaluated. The scores of the single-leg jumping course test without any stabilizing device ("standard" category) ranged between 8.06 and 13.68 (10.65 + 1.29). In the Mikros (9.95 + 0.99) and Aircast (9.99 + 1.14) brace categories, as well as the tape bandage (10.27 + 0.81) category, better scores were achieved. The differences between "standard vs Mikros" and "standard vs Aircast" revealed a significant reduction of the scores with the orthoses (P < .01). The error rate in the single-leg stance test was within the range of 0 to 16 (5.12 + 2.85) for the standard category. It was lower for the Mikros (3.65 + 2.65) and Aircast (4.17 + 2.59) categories. The error rate was highest in the tape bandage group (5.79 + 3.53). There was a significant difference between "standard vs Mikros" and "standard vs Aircast" regarding injured and non-injured ankle joints (P < .01). The angle-reproduction test showed higher values for the standard (2.36 degrees + 0.97) category than the Mikros (1.46 degrees + 0.72), Aircast (1.62 degrees + 0.91), and taping (1.84 degrees + 0.41) categories. In the standard category, the reproduction error was lower when non-injured ankle joints (2.30 degrees + 1.04) were tested than when unstable ankle joints (2.44 degrees + 0.81) were tested, whereas in all other categories the reproduction error was higher in the group of non-injured joints. According to the literature, applying a prophylactic brace can prevent an estimated 30 ankle sprains per 1000 athletic exposures.
对14名健康志愿者和16名踝关节不稳定患者的踝关节进行了功能和本体感觉能力测试。他们均为现役运动员。采用了三项测试：单腿站立测试、单腿跳跃测试和角度再现测试。评估了三种稳定装置——系带式护具（Mikros）、马镫式护具（Aircast）和绷带包扎——对稳定和不稳定踝关节本体感觉的影响。在没有任何稳定装置的单腿跳跃测试（“标准”类别）中，得分在8.06至13.68之间（10.65±1.29）。在Mikros（9.95±0.99）和Aircast（9.99±1.14）护具类别以及绷带包扎（10.27±0.81）类别中，得分更高。“标准与Mikros”以及“标准与Aircast”之间的差异显示，使用矫形器后得分显著降低（P<.01）。在单腿站立测试中，标准类别的错误率在0至16之间（5.12±2.85）。Mikros（3.65±2.65）和Aircast（4.17±2.59）类别的错误率较低。绷带包扎组的错误率最高（5.79±3.53）。在受伤和未受伤的踝关节方面，“标准与Mikros”以及“标准与Aircast”之间存在显著差异（P<.01）。角度再现测试显示，标准（2.36度±0.97）类别的值高于Mikros（1.46度±0.72）、Aircast（1.62度±0.91）和绷带包扎（1.84度±0.41）类别。在标准类别中，测试未受伤的踝关节（2.30度±1.04）时的再现误差低于测试不稳定踝关节（2.44度±0.81）时的误差，而在所有其他类别中，未受伤关节组的再现误差更高。根据文献，使用预防性护具估计每1000次运动暴露可预防30次踝关节扭伤。
