Chronic stroke patients often experience muscle weakness, reduced mobility, and impaired physical function. Eccentric contraction-based resistance exercise has been proposed as an effective intervention to improve neuromuscular function and mobility; however, its effects remain unclear. This study compared the effects of eccentric overload resistance training using a flywheel device and traditional resistance training on physical performance and muscle strength in chronic stroke patients.
This 8-week, randomized controlled trial included chronic stroke patients who were assigned to either an intervention group (INT; eccentric flywheel-based resistance exercise) or a control group (CON; conventional resistance training). Physical function was assessed based on the timed up-and-go test, 6-minute walk test, 5-times sit-to-stand test, gait speed, and isokinetic muscle strength before and after the intervention.
Of the 40 participants enrolled, 36 completed the study (INT group: n = 18; CON group: n = 18). Both groups showed improvements in physical function outcomes, such as gait speed, balance, and functional mobility, postintervention. Muscle strength also improved in both groups, with no significant between-group differences in functional or muscle strength outcomes. Subgroup analysis revealed additional benefits of eccentric training for participants with limited walking ability.
Both resistance training approaches improved physical performance in chronic stroke patients. However, eccentric overload resistance training offered additional advantages in functional mobility, particularly for patients with severe impairments. Both eccentric overload and traditional resistance training significantly improved physical performance in chronic stroke patients, highlighting the importance of structured exercise in rehabilitation.
慢性中风患者常出现肌肉无力、活动能力下降和身体功能受损。基于离心收缩的抗阻运动已被提出作为改善神经肌肉功能和活动能力的有效干预措施；然而，其效果仍不明确。本研究比较了使用飞轮装置的离心超负荷抗阻训练与传统抗阻训练对慢性中风患者身体表现和肌肉力量的影响。
这项为期8周的随机对照试验纳入了慢性中风患者，这些患者被分配到干预组（INT；基于飞轮的离心抗阻运动）或对照组（CON；传统抗阻训练）。在干预前后，根据定时起立行走测试、6分钟步行测试、5次坐立测试、步态速度和等速肌肉力量评估身体功能。
在纳入的40名参与者中，36名完成了研究（INT组：n = 18；CON组：n = 18）。两组在干预后身体功能指标均有改善，如步态速度、平衡和功能性活动能力。两组的肌肉力量也有所提高，在功能或肌肉力量指标上两组间无显著差异。亚组分析显示，离心训练对步行能力有限的参与者有额外益处。
两种抗阻训练方法均改善了慢性中风患者的身体表现。然而，离心超负荷抗阻训练在功能性活动能力方面具有额外优势，尤其是对严重受损的患者。离心超负荷训练和传统抗阻训练均显著改善了慢性中风患者的身体表现，突出了结构化运动在康复中的重要性。
