The aim of this study was to investigate whether postural control was associated with an increased risk of future noncontact ACL injury in youth female basketball and floorball athletes. Data collection on 189 youth female basketball and floorball athletes was performed during a 3-year period. The modified Star Excursion Balance Test (mSEBT), single-leg drop-down test, and single-leg stance tests on a balance platform were used to measure postural control. In the mSEBT, performance in the anteromedial, medial, and posteromedial directions, as well as the corresponding composite score, were recorded. In balance platform tests, the mediolateral and anteroposterior velocity, velocity moment, and side length of a square representing 90% of postural sway were measured. Relative limb asymmetry and bilateral limb mean results for these variables were calculated and used as predictor variables in Cox regression analysis. Noncontact ACL injuries and individual exposure hours were prospectively recorded throughout the follow-up. Twelve noncontact ACL injuries occurred. Greater limb asymmetry in the posteromedial direction [HR 1.18 (95% CI 1.05-1.32)] and composite score [HR 1.17 (95% CI 1.01-1.36)] on the mSEBT were associated with an increased risk of noncontact ACL injury. No statistically significant associations were found in the other directions for the mSEBT or any of the balance-platform-generated variables. Dynamic postural control, measured by limb asymmetry in the mSEBT, was associated with future ACL injury. Prevention programs for noncontact ACL injury could benefit from exercises directed toward correcting limb asymmetries in dynamic postural control in youth female basketball and floorball athletes.
本研究的目的是调查姿势控制是否与青年女子篮球和地板球运动员未来发生非接触性前交叉韧带损伤的风险增加有关。在3年期间对189名青年女子篮球和地板球运动员进行了数据收集。采用改良的星状偏移平衡测试（mSEBT）、单腿下蹲测试和在平衡平台上的单腿站立测试来测量姿势控制。在mSEBT中，记录前内侧、内侧和后内侧方向的表现以及相应的综合得分。在平衡平台测试中，测量代表90%姿势摆动的正方形的内外侧和前后速度、速度矩和边长。计算这些变量的相对肢体不对称性和双侧肢体平均结果，并将其用作Cox回归分析中的预测变量。在整个随访过程中前瞻性记录非接触性前交叉韧带损伤和个人暴露时间。发生了12例非接触性前交叉韧带损伤。mSEBT中后内侧方向更大的肢体不对称性[风险比（HR）1.18（95%置信区间1.05 - 1.32）]和综合得分[HR 1.17（95%置信区间1.01 - 1.36）]与非接触性前交叉韧带损伤风险增加相关。在mSEBT的其他方向或任何平衡平台产生的变量中未发现统计学上显著的关联。通过mSEBT中的肢体不对称性测量的动态姿势控制与未来的前交叉韧带损伤相关。针对青年女子篮球和地板球运动员非接触性前交叉韧带损伤的预防计划可能会受益于旨在纠正动态姿势控制中肢体不对称性的练习。
