Previous studies have demonstrated significant biomechanical differences between individuals with chronic ankle instability (CAI) and healthy controls during the Y-balance test. This study aimed to examine the effects of kinesio taping (KT) on lower limb biomechanical characteristics during the Y-balance anterior reach task in individuals with CAI.
A total of 30 participants were recruited, comprising 15 individuals with CAI and 15 healthy controls. All participants were randomly assigned three taping conditions: no taping (NT), placebo taping (PT), and KT, followed by the Y-balance anterior reach task. Each condition was separated by one-week intervals. Kinematic and kinetic data of the lower limbs during the movement phase were collected using the Vicon motion capture system (Vicon, T40, 200 Hz) and two Kistler force platforms (Kistler, 1000 Hz).
KT significantly improved the Y-balance anterior reach distance (P = 0.003) and peak ankle eversion angle (P = 0.019) compared to NT. Additionally, KT resulted in increased peak knee flexion angle (P = 0.002, P = 0.011) and peak ankle dorsiflexion angle (P <0.001, P = 0.005) relative to both NT and PT. KT also significantly reduced mediolateral center of pressure (COP) displacement (P = 0.001) and average velocity of mediolateral COP displacement (P = 0.033) in comparison to NT. Furthermore, KT decreased mediolateral center of gravity displacement (P = 0.002, P = 0.003) relative to both NT and PT.
KT significantly improved abnormal ankle posture by promoting greater ankle dorsiflexion and eversion angles. Additionally, KT reduced mediolateral COP displacement and average velocity to improve postural stability. These changes may contribute to reduced risk of ankle sprains. Therefore, KT may serve as an effective tool for managing recurrent ankle sprains in individuals with CAI.
先前的研究表明，在Y平衡测试中，慢性踝关节不稳（CAI）患者与健康对照者之间存在显著的生物力学差异。本研究旨在探讨肌内效贴布（KT）对CAI患者在Y平衡前伸任务中下肢生物力学特征的影响。
共招募30名参与者，包括15名CAI患者和15名健康对照者。所有参与者被随机分配到三种贴布条件：不贴布（NT）、安慰剂贴布（PT）和KT，然后进行Y平衡前伸任务。每种条件间隔一周。在运动阶段，使用Vicon运动捕捉系统（Vicon，T40，200Hz）和两个Kistler力平台（Kistler，1000Hz）收集下肢的运动学和动力学数据。
与NT相比，KT显著提高了Y平衡前伸距离（P = 0.003）和踝关节外翻峰值角度（P = 0.019）。此外，相对于NT和PT，KT导致膝关节屈曲峰值角度增加（P = 0.002，P = 0.011）和踝关节背屈峰值角度增加（P <0.001，P = 0.005）。与NT相比，KT还显著降低了内外侧压力中心（COP）位移（P = 0.001）和内外侧COP位移的平均速度（P = 0.033）。此外，相对于NT和PT，KT降低了内外侧重心位移（P = 0.002，P = 0.003）。
KT通过促进更大的踝关节背屈和外翻角度，显著改善了异常的踝关节姿势。此外，KT减少了内外侧COP位移和平均速度，以提高姿势稳定性。这些变化可能有助于降低踝关节扭伤的风险。因此，KT可能是管理CAI患者复发性踝关节扭伤的有效工具。
