To explore the effect of different lengths of kinesiology taping (KT) on dynamic balance control in individuals with and without chronic ankle instability (CAI). Thirty-one participants (16 CAI, 15 non-CAI) volunteered, and all of them were tested for dynamic balance with KT taping of varied strip lengths, in a random sequence, with taping conditions being: above-ankle taping (short taping), below-knee taping (mid taping), and above-knee taping (long taping). Dynamic balance was measured by the Y-Balance test (YBT) with three reaching directions; anterior (YBT-A), posteromedial (YBT-PM), posterolateral (YBT-PL), untaped at enrolment and immediately after each taping condition. Non-CAI participants consistently outperformed CAI all YBT measures made in the untaped condition (all p<0.05). Linear mixed model (LMM) analysis suggested there were significant KT-Group interactions reflecting reducing inter-group difference as tape length increased for YBT-C (F = 5.599, p = 0.016, ES = 0.104), YBT-PM (F = 3.53, p = 0.018, ES = 0.102) and YBT-PL (F = 2.72, p = 0.049, ES = 0.008), but not YBT-A (F = 1.44, p = 0.236). Paired t-tests suggested that in the CAI group, compared to the untaped condition, YBT-PM scores increased in all taping conditions, with mean difference (MD) from 3.5 to 7.0% (t = 2.17-5.17, p = 0.00-0.046, 95%CI = -9.83, -0.07), whereas YBT-C (MD = 4.2%, t = 1.03, p = 0.001, 95%CI = -6.36, -1.97) and YBT-PL scores (MD = 5.3%, t = 3.9, p = 0.001, 95%CI = -8.18, -2.41) increased only in the long-taping condition. KT taping can improve dynamic balance for individuals with CAI to a level of those without CAI. Longer KT taping seems to show superior effects. However, individuals without CAI may not benefit from KT taping when performing a dynamic balance task.
为探究不同长度的肌内效贴布（KT）对有无慢性踝关节不稳（CAI）个体动态平衡控制的影响。31名参与者（16名CAI患者，15名非CAI患者）自愿参与，所有人均以随机顺序接受不同条带长度的KT贴扎测试动态平衡，贴扎条件分别为：踝关节上方贴扎（短贴扎）、膝关节下方贴扎（中贴扎）和膝关节上方贴扎（长贴扎）。通过Y平衡测试（YBT）在三个伸展方向测量动态平衡，即前向（YBT-A）、后内侧（YBT-PM）、后外侧（YBT-PL），在入组时未贴扎以及每种贴扎条件后立即进行测量。在未贴扎条件下进行的所有YBT测量中，非CAI参与者的表现始终优于CAI参与者（所有p<0.05）。线性混合模型（LMM）分析表明，存在显著的KT-组交互作用，反映出随着贴布长度增加，YBT-C（F = 5.599，p = 0.016，ES = 0.104）、YBT-PM（F = 3.53，p = 0.018，ES = 0.102）和YBT-PL（F = 2.72，p = 0.049，ES = 0.008）的组间差异减小，但YBT-A（F = 1.44，p = 0.236）不存在这种情况。配对t检验表明，在CAI组中，与未贴扎条件相比，所有贴扎条件下YBT-PM得分均增加，平均差异（MD）为3.5%至7.0%（t = 2.17 - 5.17，p = 0.00 - 0.046，95%CI = -9.83，-0.07），而YBT-C（MD = 4.2%，t = 1.03，p = 0.001，95%CI = -6.36，-1.97）和YBT-PL得分（MD = 5.3%，t = 3.9，p = 0.001，95%CI = -8.18，-2.41）仅在长贴扎条件下增加。KT贴扎可将CAI个体的动态平衡改善至非CAI个体的水平。较长的KT贴扎似乎显示出更好的效果。然而，非CAI个体在执行动态平衡任务时可能无法从KT贴扎中获益。
