To investigate effectiveness of a functional strengthening program, the loaded sit-to-stand (STS) resistance exercise, for children with cerebral palsy (CP).
A single-blind, randomized block design.
STS exercises were carried out at the children's homes.
Twenty children (12 boys, 8 girls; age range, 5-12y) with spastic diplegia CP and classified by the Gross Motor Function Classification System as level I or II were stratified by their severity and age and randomly allocated into either the experimental or control group.
Both groups received their regular physical therapy. The experimental group underwent loaded STS exercise 3 times a week for 6 weeks.
Goal dimension scores of the Gross Motor Function Measure (GMFM), gait speed, 1 repetition maximum (1-RM) of the loaded STS, isometric strength of knee extensor, and Physiological Cost Index (PCI). The outcome measures were conducted at the beginning and end of the 6-week study.
After loaded STS exercise, the experimental group showed statistically significant differences in GMFM goal dimension scores, 1-RM STS, and PCI from the control group. The changes in gait speed and isometric strength of the knee extensor did not differ significantly between the 2 groups.
After the loaded STS exercise, children with mild spastic diplegia improved their basic motor abilities, functional muscle strength, and walking efficiency.
探讨功能性强化训练计划，即负重坐立位转换（STS）抗阻运动，对脑瘫（CP）患儿的有效性。
单盲随机区组设计。
在患儿家中进行STS训练。
20名痉挛型双瘫脑瘫患儿（12名男孩，8名女孩；年龄范围5 - 12岁），根据粗大运动功能分类系统分为I级或II级，按严重程度和年龄分层，随机分为实验组或对照组。
两组均接受常规物理治疗。实验组每周进行3次负重STS运动，共6周。
粗大运动功能测量（GMFM）目标维度评分、步态速度、负重STS的1次重复最大量（1-RM）、膝伸肌等长肌力和生理成本指数（PCI）。在为期6周的研究开始和结束时进行观察指标的测量。
负重STS运动后，实验组在GMFM目标维度评分、1-RM STS和PCI方面与对照组相比有统计学显著差异。两组之间步态速度和膝伸肌等长肌力的变化无显著差异。
负重STS运动后，轻度痉挛型双瘫患儿的基本运动能力、功能性肌肉力量和步行效率得到改善。
