目的:大多数对踝关节应用Kinesio绑扎(KT)的生物力学研究都集中在测试预期的运动。然而,脚踝扭伤在现实生活中经常发生在意想不到的情况下,个人毫无准备,面临突然的外部刺激。这种情况与预期的情况完全不同。本研究的目的是研究在大学运动员的意外跳跃任务中,踝关节KT应用对膝关节和踝关节的运动学和动力学特性的影响。
方法:18名健康的大学运动员按随机顺序经历了三种录音条件:无录音(NT),安慰剂录音(PT),还有KT,并执行了意想不到的跳跃任务。采用9摄像头红外高速运动捕捉系统收集膝盖和脚踝运动学数据,在任务期间,使用3维力板收集膝盖和脚踝的动力学数据。
结果:在右跳期间,与NT相比,KT显着增加了峰值膝关节屈曲角度(P=0.031),与NT和PT相比,峰值垂直地面反作用力显着降低(P<0.001,P=0.001)。在左跳的时候,与NT和PT相比,KT显着降低了峰值踝关节内翻角度(P=0.022,P<0.001)和峰值踝关节内翻力矩(P=0.002,P=0.001)。
结论:在意外的跳跃动作中,KT降低了峰值踝关节内翻角度,峰值垂直地面反作用力,大学运动员的踝关节内翻力矩峰值和膝关节屈曲角度峰值增加。
OBJECTIVE: Most biomechanical research on the application of Kinesio taping (KT) to the ankle joint focused on testing anticipated movements. However, ankle sprains frequently occur in real life in unanticipated situations, where individuals are unprepared and face sudden external stimuli. This situation is completely different from the anticipated situation. The aim of the present study was to investigate the effects of ankle KT application on the kinematic and kinetic characteristics of the knee and ankle joints during unanticipated jump tasks in collegiate athletes.
METHODS: Eighteen healthy collegiate athletes experienced three taping conditions in a randomized order: no taping (NT), placebo taping (PT), and KT, and performed unanticipated jump tasks. A 9-camera infrared high-speed motion capture system was employed to collect knee and ankle kinematic data, and a 3-dimensional force plate was utilized to collect knee and ankle kinetic data during the tasks.
RESULTS: During the right jumps, KT significantly increased peak knee flexion angle (P = 0.031) compared to NT and significantly decreased peak vertical ground reaction force (P < 0.001, P = 0.001) compared to NT and PT. During the left jumps, KT significantly reduced peak ankle inversion angle (P = 0.022, P < 0.001) and peak ankle inversion moment (P = 0.002, P = 0.001) compared to NT and PT.
CONCLUSIONS: During unanticipated jump maneuvers, KT reduced peak ankle inversion angle, peak vertical ground reaction force, and peak ankle inversion moment and increased peak knee flexion angle in collegiate athletes.
