Dynamic tape is one of the options for supporting the foot arch in the management of arch-related disorders. However, its mechanical effects on the foot arch remain unclear, particularly under cyclic loading. This study aims to investigate the initial effects of dynamic taping on maintaining foot arch height under cyclic loading among university students.
Thirty-three asymptomatic participants were enrolled in this study. The dynamic tape was applied to the foot with the lower arch to provide support, and the other foot remained untaped as a control. The tape was applied without pre-tension and simply laid straight. Changes in bilateral foot arch height and index were measured using a commercial foot sole morphology assessment device and compared after 6 and 12 min of walking.
The arch height did not decrease significantly after walking for 6 or 12 min in either the taped or untaped foot. However, the arch index of the taped foot increased significantly (from 0.258 ± 0.086 to 0.273 ± 0.085) after 12 min of walking, whereas no significant change was observed in the untaped foot.
This study is the first to evaluate the initial effect of dynamic tape applied without pre-tension on foot arch support by directly measuring sole morphology using a pin-array impression device. The results indicate that dynamic tape without pre-tension does not effectively prevent the immediate reduction in foot arch height after application. Further research is needed to determine the optimal balance between pre-tension and therapeutic efficacy.
动态贴布是足弓相关疾病管理中支撑足弓的选择之一。然而，其对足弓的力学影响仍不清楚，尤其是在循环加载下。本研究旨在调查动态贴布对大学生在循环加载下维持足弓高度的初始影响。
33名无症状参与者纳入本研究。将动态贴布应用于足弓较低的足部以提供支撑，另一只脚不贴布作为对照。贴布时不施加预张力，直接平铺。使用商用足底形态评估装置测量双侧足弓高度和指数的变化，并在行走6分钟和12分钟后进行比较。
贴布足和未贴布足在行走6分钟或12分钟后足弓高度均无显著下降。然而，贴布足在行走12分钟后足弓指数显著增加（从0.258±0.086增至0.273±0.085），而未贴布足未观察到显著变化。
本研究首次通过使用针阵列压印装置直接测量足底形态，评估了无预张力的动态贴布对足弓支撑的初始效果。结果表明，无预张力的动态贴布不能有效防止应用后足弓高度立即降低。需要进一步研究以确定预张力与治疗效果之间的最佳平衡。
