Stabilization of the ankle joint is used as a deterrent to injury, however, insufficient or excessive ankle control can cause negative effects. This study determined the effects of systematic changes in ankle and subtalar joint stabilization on performance through an obstacle course. Data were collected on six subjects as they completed two test procedures. Ankle range of motion in the sagittal and frontal planes was determined using a modified Inman apparatus. Completion time through an obstacle course, set up on a basketball court, was used as a measure of performance. High-top basketball shoes were constructed with pockets which allowed strips of plastic (stiffeners) to be positioned just anterior and posterior to the medial and lateral malleoli. Four shoe conditions were used including the shoe with no stiffeners. Significant differences (P less than 0.05) in eversion, flexion, and inversion were found between the shoe conditions. A general trend of decreased range of motion with increased restriction was observed. Significant differences (P less than 0.05) in performance were found between the shoe conditions, with a general trend of increased times with increased restriction. These results indicate that systematic changes in the range of motion of the ankle and subtalar joints can measurably affect performance.
踝关节稳定可预防受伤，然而，踝关节控制不足或过度都会产生负面影响。本研究通过障碍测试，确定踝关节和距下关节稳定的系统性变化对运动表现的影响。在六名受试者完成两项测试程序时收集数据。使用改良的英曼器械测定矢状面和额状面的踝关节活动范围。以在篮球场上设置的障碍测试的完成时间作为运动表现的衡量指标。高帮篮球鞋设有口袋，可在内、外踝前后放置塑料条（加固条）。使用了四种鞋类条件，包括未加加固条的鞋子。不同鞋类条件下，外翻、屈曲和内翻存在显著差异（P<0.05）。观察到随着限制增加，活动范围减小的总体趋势。不同鞋类条件下，运动表现存在显著差异（P<0.05），随着限制增加，时间增加的总体趋势明显。这些结果表明，踝关节和距下关节活动范围的系统性变化可显著影响运动表现。
