Goal: To determine the efficacy of wearable adaptive resistance training for rapidly improving walking ability in children with cerebral palsy (CP). Methods: Six children with spastic CP (five males, one female; mean age 14y 11mo; three hemiplegic, three diplegic; Gross Motor Function Classification System [GMFCS] levels I and II) underwent ten, 20-minute training sessions over four weeks with a wearable adaptive resistance device. Strength, speed, walking efficiency, timed up and go (TUG), and six-minute walk test (6MWT) were used to measure training outcomes. Results: Participants showed increased average plantar flexor strength (17 ± 8%, p = 0.02), increased preferred walking speed on the treadmill (39 ± 25%, p = 0.04), improved metabolic cost of transport (33 ± 9%, p = 0.03), and enhanced performance on the timed up and go (11 ± 9%, p = 0.04) and six-minute walk test (13 ± 9%, p = 0.04). Conclusions: The observed increase in preferred walking speed, reduction in metabolic cost of transport, and improved performance on clinical tests of mobility highlights the potentially transformative nature of this novel therapy; the rate at which this intervention elicited improved function was 3 – 6 times greater than what has been reported previously.

可穿戴式自适应阻力训练可提高脑瘫患者的脚踝力量、行走效率和活动能力：一项试点临床试验


目标：确定可穿戴式适应性阻力训练对于快速提高脑瘫 (CP) 儿童步行能力的功效。方法：6 名痉挛性 CP 儿童（5 名男性，1 名女性；平均年龄 14 岁 11 个月；3 名偏瘫，3 名瘫痪；粗大运动功能分类系统 [GMFCS] 级别 I 和 II）在 4 周内接受了 10 次 20 分钟的训练课程，可穿戴自适应阻力装置。力量、速度、步行效率、计时起跑 (TUG) 和六分钟步行测试 (6MWT) 用于衡量训练结果。结果：参与者的平均跖屈肌力量增加（17 ± 8%，p = 0.02），跑步机上的首选行走速度增加（39 ± 25%，p = 0.04），交通代谢成本改善（33 ± 9%，p = 0.03），并增强了计时起跑测试（11 ± 9%，p = 0.04）和六分钟步行测试（13 ± 9%，p = 0.04）的性能。结论：观察到的首选步行速度的增加、运输代谢成本的降低以及活动性临床测试表现的改善凸显了这种新疗法的潜在变革性；这种干预措施改善功能的速度是之前报道的 3 至 6 倍。
