CONTEXT
Diminished hip-abductor strength has been suggested to increase the risk of noncontact lateral ankle sprains.
OBJECTIVE
To determine prospectively whether baseline hip-abductor strength predicts future noncontact lateral ankle sprains in competitive male soccer players.
DESIGN
Prospective cohort study.
SETTING
Athletic training facilities and various athletic fields.
PATIENTS OR OTHER PARTICIPANTS
Two hundred ten competitive male soccer players.
MAIN OUTCOME MEASURE(S): Before the start of the sport season, isometric hip-abductor strength was measured bilaterally using a handheld dynamometer. Any previous history of ankle sprain, body mass index, age, height, and weight were documented. During the sport season (30 weeks), ankle injury status was recorded by team medical providers. Injured athletes were further classified based on the mechanism of injury. Only data from injured athletes who sustained noncontact lateral ankle sprains were used for analysis. Postseason, logistic regression was used to determine whether baseline hip strength predicted future noncontact lateral ankle sprains. A receiver operating characteristic curve was constructed for hip strength to determine the cutoff value for distinguishing between high-risk and low-risk outcomes.
RESULTS
A total of 25 noncontact lateral ankle sprains were confirmed, for an overall annual incidence of 11.9%. Baseline hip-abductor strength was lower in injured players than in uninjured players ( P = .008). Logistic regression indicated that impaired hip-abductor strength increased the future injury risk (odds ratio = 1.10 [95% confidence interval = 1.02, 1.18], P = .010). The strength cutoff to define high risk was ≤33.8% body weight, as determined by receiver operating characteristic curve analysis. For athletes classified as high risk, the probability of injury increased from 11.9% to 26.7%.
CONCLUSIONS
Reduced isometric hip-abductor strength predisposed competitive male soccer players to noncontact lateral ankle sprains.
背景
髋外展肌力量减弱被认为会增加非接触性外侧踝关节扭伤的风险。
目的
前瞻性确定基线髋外展肌力量是否可预测竞技男性足球运动员未来的非接触性外侧踝关节扭伤。
设计
前瞻性队列研究。
设置
运动训练设施和各种运动场地。
患者或其他参与者
210 名竞技男性足球运动员。
主要观察指标
在运动赛季开始前，使用手持测力计双侧测量等长髋外展肌力量。记录任何先前的踝关节扭伤史、身体质量指数、年龄、身高和体重。在运动赛季（30 周）期间，由队医记录踝关节损伤情况。受伤运动员根据损伤机制进一步分类。仅使用发生非接触性外侧踝关节扭伤的受伤运动员的数据进行分析。赛后，使用逻辑回归确定基线髋部力量是否可预测未来的非接触性外侧踝关节扭伤。构建受试者工作特征曲线以确定区分高风险和低风险结果的髋部力量截断值。
结果
共确认 25 例非接触性外侧踝关节扭伤，总体年发生率为 11.9%。受伤运动员的基线髋外展肌力量低于未受伤运动员（P =.008）。逻辑回归表明，髋外展肌力量减弱增加了未来受伤的风险（优势比=1.10[95%置信区间=1.02，1.18]，P =.010）。通过受试者工作特征曲线分析确定，定义高风险的力量截断值为≤33.8%体重。对于分类为高风险的运动员，受伤的概率从 11.9%增加到 26.7%。
结论
等长髋外展肌力量减弱使竞技男性足球运动员易患非接触性外侧踝关节扭伤。
