[Purpose] The purpose of this study was to examine the effect of kinetic chain exercise using EMG-biofeedback on balance and lower extremity muscle activation. [Subjects and Methods] For this study, 30 stroke patients participated in this study and they were divided into closed kinetic chain exercise using EMG-biofeedback group (CKCE+EB) and open kinetic chain exercise using EMG-biofeedback group (OKCE+EB), each group consisting of 15 patients. The kinetic chain exercise using EMG-biofeedback was performed by the patients for 20 minutes once a day, 5 days a week, for 6 weeks using an Myo-Ex. BioRescue was used to measure balance ability, while surface EMG was used to measure the lower extremity muscle activation. [Results] According to the results of the comparison within the groups, after the intervention, both groups showed significant increases in the balance ability and lower extremity muscle activation. In the comparisons between the groups, after the intervention, balance ability and lower extremity muscle activation were significantly higher in the CKCE+BE than in the OKCE+EB. [Conclusion] This study showed that closed kinetic chain exercise using EMG-biofeedback is effective for improving balance ability and lower extremity muscle activation in stroke patients.
[目的]本研究旨在探讨肌电图生物反馈动力链运动对平衡能力及下肢肌肉激活的影响。[对象与方法]本研究中，30例中风患者参与，分为肌电图生物反馈闭链运动组（CKCE+EB）和肌电图生物反馈开链运动组（OKCE+EB），每组15例患者。使用肌电图生物反馈的动力链运动由患者每天进行1次，每次20分钟，每周5天，共6周，使用Myo-Ex设备。采用BioRescue测量平衡能力，同时使用表面肌电图测量下肢肌肉激活情况。[结果]根据组内比较结果，干预后两组的平衡能力和下肢肌肉激活均显著增加。组间比较中，干预后CKCE+BE组的平衡能力和下肢肌肉激活显著高于OKCE+EB组。[结论]本研究表明，肌电图生物反馈闭链运动对改善中风患者的平衡能力和下肢肌肉激活有效。
