BACKGROUND
Competitive adolescent athletes should be aware of the early signs of chronic ankle instability (CAI) and the connection between the condition and performance.
PURPOSE
To investigate whether CAI is related to foot alignment and morphology as well as dynamic postural stability after a jump landing among adolescent competitive athletes with and without a history of a lateral ankle sprain and CAI.
STUDY DESIGN
Cross-sectional study; Level of evidence, 3.
METHODS
Between July 2020 and August 2021, adolescent competitive athletes (N = 85; n = 49 boys; n = 36 girls) were classified into 3 groups using Cumberland Ankle Instability Tool (CAIT) scores: healthy athletes (n = 55), coper athletes (n = 19), and athletes with CAI (n = 11). Results of foot alignment assessments involving the leg-heel angle (LHA) and navicular height, intrinsic foot muscle morphology, dynamic postural stability index (DPSI), and other parameters were compared among the 3 groups. The relationship between the CAIT score and the LHA and dynamic postural stability and instability were examined using multiple linear regression.
RESULTS
Compared with the healthy group, the CAI group had a significantly greater LHA (8.73°± 3.22° vs 6.09°± 3.26°; < .05), higher DPSI (0.336 ± 0.046 vs 0.298 ± 0.035), and higher vertical stability index (0.303 ± 0.048 vs 0.264 ± 0.037; < .05 for all). Multiple regression analysis showed that the LHA (β = -0.228; = .033) and DPSI (β = -0.240; = .025) were significantly associated with the CAIT score .
CONCLUSION
Valgus rearfoot alignment and poorer dynamic postural control were associated with CAI among adolescent athletes.
背景
有竞争力的青少年运动员应了解慢性踝关节不稳（CAI）的早期症状以及该病症与运动表现之间的联系。
目的
调查在有或无外侧踝关节扭伤和CAI病史的青少年竞技运动员中，CAI是否与足部对线和形态以及跳跃着陆后的动态姿势稳定性相关。
研究设计
横断面研究；证据等级，3级。
方法
在2020年7月至2021年8月期间，使用坎伯兰踝关节不稳工具（CAIT）评分将青少年竞技运动员（N = 85；49名男孩；36名女孩）分为3组：健康运动员（n = 55）、恢复良好运动员（n = 19）和患有CAI的运动员（n = 11）。比较3组之间涉及小腿-足跟角（LHA）和舟骨高度的足部对线评估结果、足部固有肌肉形态、动态姿势稳定性指数（DPSI）和其他参数。使用多元线性回归检查CAIT评分与LHA以及动态姿势稳定性和不稳定性之间的关系。
结果
与健康组相比，CAI组的LHA显著更大（8.73°± 3.22°对6.09°± 3.26°；P <.05），DPSI更高（0.336 ± 0.046对0.298 ± 0.035），垂直稳定性指数更高（0.303 ± 0.048对0.264 ± 0.037；所有P <.05）。多元回归分析表明，LHA（β = -0.228；P = .033）和DPSI（β = -0.240；P = .025）与CAIT评分显著相关。
结论
青少年运动员中，后足外翻对线和较差的动态姿势控制与CAI相关。
