摘　　要：背景:在跳跃落地的过程中,踝关节内翻扭伤频繁发生,这一动作常导致距腓前韧带和跟腓韧带受损。以往的研究常采用内翻角度等指标来代表损伤风险,这些指标与踝扭伤的关系缺乏数据支持。目的:通过三维多体足踝模型,计算下落跳时的距腓前韧带和跟腓韧带应变,探讨增加足外展角度落地是否会降低内翻扭伤风险。方法:共招募35名高运动需求的健康参与者,其中男性15名,女性20名;年龄(21.0±0.9)岁;身高(176.2±8.8)cm;体质量(71.6±12.8)kg。使用活板门装置进行下落跳测试模拟踝关节内翻扭伤。测试过程中,参与者被要求分别在自然着地和外展着地两种状态下跳落在活板门上,使用12摄像头三维红外动作捕捉系统来记录参与者的运动学数据,随后利用这些运动学数据驱动三维多体足踝模型,计算距腓前韧带和跟腓韧带的应变。结果与结论:与自然着地状态相比,在外展着地状态下,距腓前韧带的应变显著降低[自然着地:(3.57±1.92)%,足外展着地:(0.36±1.18)%,P<0.001,Cohen’s d=2.01],同时跟腓韧带的应变也显著降低[自然着地:(1.38±1.80)%,足外展着地:(0.28±2.29)%,P=0.003,Cohen’s d=0.81]。这些结果表明,外展着地可以有效降低下落跳时踝关节内翻状态下的距腓前韧带和跟腓韧带应变,进而减少踝关节内翻扭伤的风险。BACKGROUND:Ankle inversion injuries frequently occur during landing,injuring the anterior talofibular and calcaneofibular ligaments.Previous studies usually used indirect indicators,such as inversion angle,as an injury risk indicator,but epidemiological support is lacking.OBJECTIVE:To calculate anterior talofibular and calcaneofibular ligament strains using a three-dimensional multi-body foot model during a drop-landing and to investigate whether increasing the foot toe-out angle for landing would reduce the risk of inversion sprains.METHODS:Thirty-five participants with high sports demands[15 males and 20 females,age:(21.0±0.9)years,height:(176.2±8.8)cm,body mass:(71.6±12.8)kg]were recruited to perform a drop-landing test using a trapdoor device to simulate ankle inversion sprains.Two landing conditions were tested,i.e.,natural landing and toe-out landing.Kinematic data were collected using a 12-camera motion analysis system,the strains of the anterior talofibular and calcaneofibular ligaments were calculated using a three-dimensional rigid-body foot model.RESULTS AND CONCLUSION:From natural landing to toe-out landing conditions,the anterior talofibular ligament strain decreased[natural landing=(3.57±1.92)%,toe-out landing=(0.36±1.18)%,P<0.001,Cohen’s d=2.01],as was the calcaneofibular ligament strain[natural landing=(1.38±1.80)%,toe-out landing=(0.28±2.29)%,P=0.003,Cohen’s d=0.81].It could be concluded that increasing foot toe-out angle reduces anterior talofibular and calcaneofibular ligament strains during drop-landing with ankle inversion,thereby reducing the potential of ankle inversion sprains.
