鞋帮高度对侧切动作踝关节生物力学特征的影响

Effects of Shoe Collar Height on Ankle Joint Kinematics and Kinetics during Side-cutting Task

慢性踝关节不稳是篮球运动中常见伤病,可导致再次扭伤风险增大。高帮球鞋是预防扭伤的常用手段,但是否对踝关节不稳者具有防护作用仍不明确。确定鞋帮高度对有、无慢性踝关节不稳者侧切时踝关节生物力学特征的影响。选取13名慢性踝关节不稳者和13名对照者分别穿着高、低帮球鞋进行45°侧切变向动作,通过红外运动捕捉系统和测力台采集踝关节运动学和动力学数据。慢性踝关节不稳者和对照者穿着高帮球鞋侧切时最大踝内翻角、最大踝内翻角速度和踝内翻活动幅度均小于低帮。高帮球鞋在一定程度上可提高踝关节侧向稳定性和降低扭伤风险,且对慢性踝关节不稳者与正常者均具有相同的防护效果。

Chronic ankle instability(CAI)is the most common injury in basketball,which could lead to high risk for recurrent ankle sprains.High-top shoes are commonly used to prevent ankle sprains,but it is still unclear whether they have a protective effect on CAI.The effects of shoe collar height on ankle joint kinematics and kinetics during side-cutting task in individuals with and without chronic ankle instability should be determined.Thirteen participants with CAI and 13 healthy control participants wore high-top and low-top basketball shoes performed side-cutting task,ankle kinematics and kinetics data were collected by using motion capture system and force platform.Wearing high-top shoes resulted in smaller peak ankle inversion angle,perk ankle inversion velocity and total range of inversion during side-cutting task for both CAI and control groups.Wearing high-top basketball shoes could improve the lateral stability and reduce the risk of ankle sprains for both individuals with and without CAI.
