[Purpose] This study aimed to investigate the effects of ankle biofeedback training on muscle strength of the ankle joint, balance, and gait in stroke patients. [Subjects and Methods] Twenty-seven subjects who had had a stroke were randomly allocated to either the ankle biofeedback training group (n=14) or control group (n=13). Conventional therapy, which adhered to the neurodevelopmental treatment approach, was administered to both groups for 30 minutes. Furthermore, ankle strengthening exercises were performed by the control group and ankle biofeedback training by the experimental group, each for 30 minutes, 5 days a week for 8 weeks. To test muscle strength, balance, and gait, the Biodex isokinetic dynamometer, functional reach test, and 10 m walk test, respectively, were used. [Results] After the intervention, both groups showed a significant increase in muscle strength on the affected side and improved balance and gait. Significantly greater improvements were observed in the balance and gait of the ankle biofeedback training group compared with the control group, but not in the strength of the dorsiflexor and plantar flexor muscles of the affected side. [Conclusion] This study showed that ankle biofeedback training significantly improves muscle strength of the ankle joint, balance, and gait in patients with stroke.
[目的] 本研究旨在探讨踝关节生物反馈训练对脑卒中患者踝关节肌肉力量、平衡能力和步态的影响。[对象与方法] 27例脑卒中患者被随机分为踝关节生物反馈训练组（n = 14）和对照组（n = 13）。两组均接受30分钟遵循神经发育治疗方法的常规治疗。此外，对照组进行踝关节强化训练，实验组进行踝关节生物反馈训练，均为每周5天，每次30分钟，共8周。分别使用Biodex等速测力计、功能性伸展测试和10米步行测试来检测肌肉力量、平衡能力和步态。[结果] 干预后，两组患侧肌肉力量均显著增加，平衡能力和步态均有所改善。与对照组相比，踝关节生物反馈训练组的平衡能力和步态改善更为显著，但患侧背屈肌和跖屈肌的力量无明显差异。[结论] 本研究表明，踝关节生物反馈训练可显著改善脑卒中患者的踝关节肌肉力量、平衡能力和步态。
