This study aimed to determine the effects of balance training with weight shift-triggered electrical stimulation to improve balance, lower-extremity motor function, and activities of daily living in patients with stroke. The participants were randomly allocated to the balance training with electrical stimulation group (BT-ESG, = 29) or the balance training group (BTG, = 30). Both groups were trained 5 times per week for 6 weeks for 50 min per session. To evaluate static balance, postural sway was assessed and dynamic balance was assessed using the Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and functional reach test (FRT). Lower-extremity motor function was assessed using the Fugl-Meyer assessment. Daily activities were assessed using the Modified Barthel Index. As for static balance, BT-ESG showed a significant improvement compared to BTG in postural swat in both the eyes-open (velocity moment; effect size, 0.88; 95% confidence interval, -1.16 to -1.30), or eyes-closed state (velocity moment; effect size, 0.81; 95% confidence interval, -1.22 to -0.27). Dynamic balance, which includes TUG (effect size, 0.90; 95% confidence interval, -4.67 to -1.25), BBS (effect size, 1.26; 95% confidence interval, -2.84 to 6.83), and FRT (effect size, 1.45; 95% confidence interval, 1.92 to 4.08), in addition to lower-extremity motor function (effect size, 1.38; 95% confidence interval, 2.25 to 4.97), and activities of daily living (effect size, 2.04; 95% confidence interval, 2.04 to 937), showed significant improvement in BT-ESG compared to BTG. These results suggest that balance training with weight shift-triggered electrical stimulation effectively improves balance, lower-extremity motor function, and activities of daily living in patients with stroke.
本研究旨在确定体重转移触发电刺激的平衡训练对改善中风患者的平衡能力、下肢运动功能和日常生活活动能力的效果。参与者被随机分配到电刺激平衡训练组（BT - ESG，n = 29）或平衡训练组（BTG，n = 30）。两组均每周训练5次，共6周，每次训练50分钟。为评估静态平衡，通过评估姿势摆动来进行，动态平衡则使用伯格平衡量表（BBS）、定时起立行走测试（TUG）和功能性伸展测试（FRT）进行评估。下肢运动功能使用Fugl - Meyer评估法进行评估。日常生活活动能力使用改良巴氏指数进行评估。在静态平衡方面，与BTG相比，BT - ESG在睁眼（速度矩；效应量，0.88；95%置信区间，-1.16至-1.30）或闭眼状态（速度矩；效应量，0.81；95%置信区间，-1.22至-0.27）下的姿势摆动均有显著改善。动态平衡方面，包括TUG（效应量，0.90；95%置信区间，-4.67至-1.25）、BBS（效应量，1.26；95%置信区间，-2.84至6.83）和FRT（效应量，1.45；95%置信区间，1.92至4.08），此外还有下肢运动功能（效应量，1.38；95%置信区间，2.25至4.97）和日常生活活动能力（效应量，2.04；95%置信区间，2.04至937），与BTG相比，BT - ESG均有显著改善。这些结果表明，体重转移触发电刺激的平衡训练能有效改善中风患者的平衡能力、下肢运动功能和日常生活活动能力。
