经皮神经电刺激联合弹力带训练提升功能性慢踝患者运动能力的作用效果及其机制研究

Effect of Transcutaneous Electrical Nerve Stimulation Combined with Elastic Band Training on Improving Exercise Capacity in Patients with Functional Chronic Ankle Instability and Its Mechanism

摘要: 目的：本研究旨在探讨经皮神经电刺激(TENS)联合弹力带训练对慢性踝关节不稳定(CAI)患者运动能力的改善效果及其潜在机制。方法：研究招募45名CAI患者，随机分为经皮神经电刺激组、弹力带训练组和TENS联合弹力带训练组。干预周期为6周，实验前后分别测试受试者的肌肉电活动水平、动态平衡能力及静态平衡能力，并使用SPSS22.0统计分析。结果：6周干预后，所有受试者的肌电活动水平、动态平衡能力及静态平衡能力均有显著改善(p < 0.05)，但TENS联合弹力带训练组的改善幅度最大，显著优于单独训练组(p < 0.05)。结论：TENS联合弹力带训练能通过提高神经肌肉控制和肌肉力量，优化运动单位激活模式，提高踝关节稳定性，为CAI患者提供一种高效的康复策略。

Abstract: Objective: This study aimed to investigate the effect of transcutaneous electrical nerve stimulation (TENS) combined with elastic band training on improving exercise capacity in patients with chronic ankle instability (CAI) and explore its underlying mechanisms. Methods: Forty-five CAI patients were recruited and randomly assigned to a TENS group, an elastic band training group, or a combined TENS and elastic band training group. The intervention lasted 6 weeks. Muscle electrical activity, dynamic balance, and static balance were assessed before and after the intervention. Data were analyzed using SPSS 22.0. Results: After 6 weeks, all groups showed significant improvements in muscle activity, dynamic balance, and static balance (p < 0.05). However, the combined TENS and elastic band training group exhibited the greatest improvement, significantly outperforming the single-intervention groups (p < 0.05). Conclusion: The combination of TENS and elastic band training enhances neuromuscular control and muscle strength by optimizing motor unit activation patterns, thereby improving ankle stability. This approach provides an effective rehabilitation strategy for CAI patients.
