[Purpose] This study examined the effects of balance training by applying knee joint movements on muscle activity in male adults with functional ankle instability. [Subjects and Methods] 28 adults with functional ankle instability, divided randomly into an experimental group, which performed balance training by applying knee joint movements for 20 minutes and ankle joint exercises for 10 minutes, and a control group, which performed ankle joint exercise for 30 minutes. Exercises were completed three times a week for 8 weeks. Electromyographic values of the tibialis anterior, peroneus longus, peroneus brevis, and the lateral gastrocnemius muscles were obtained to compare and analyze muscle activity before and after the experiments in each group. [Results] The experimental group had significant increases in muscle activity in the tibialis anterior, peroneus longus, and lateral gastrocnemius muscles, while muscle activity in the peroneus brevis increased without significance. The control group had significant increases in muscle activity in the tibialis anterior and peroneus longus, while muscle activity in the peroneus brevis and lateral gastrocnemius muscles increased without significance. [Conclusion] In conclusion, balance training by applying knee joint movements can be recommended as a treatment method for patients with functional ankle instability.
[目的] 本研究通过应用膝关节运动来检验平衡训练对功能性踝关节不稳男性成年人肌肉活动的影响。[对象与方法] 28名功能性踝关节不稳的成年人，随机分为实验组和对照组。实验组进行20分钟的膝关节运动平衡训练和10分钟的踝关节运动，对照组进行30分钟的踝关节运动。每周进行3次训练，共8周。获取胫骨前肌、腓骨长肌、腓骨短肌和外侧腓肠肌的肌电图值，以比较和分析每组实验前后的肌肉活动情况。[结果] 实验组胫骨前肌、腓骨长肌和外侧腓肠肌的肌肉活动显著增加，而腓骨短肌的肌肉活动虽有增加但不显著。对照组胫骨前肌和腓骨长肌的肌肉活动显著增加，而腓骨短肌和外侧腓肠肌的肌肉活动虽有增加但不显著。[结论] 总之，应用膝关节运动的平衡训练可作为功能性踝关节不稳患者的一种治疗方法推荐使用。
