[Purpose] The purpose of this study was to compare differences in respiratory pressure and pulmonary function and the effectiveness of respiratory feedback training according to walking ability in children with cerebral palsy (CP). [Subjects and Methods] Twenty-three children with spastic CP were enrolled in the final analysis and were divided into an independent walking group (n=12) and non-independent walking group. All children received respiratory feedback training for four weeks. Before and after the training, respiratory muscle strength was measured and a pulmonary function test was performed. [Results] Comparison of respiratory pressure and pulmonary function test results between the two revealed that the independent walking group had significantly higher respiratory function than the other group in all variables except peak expiratory flow. In comparison of changes in respiratory function between the two groups, the independent walking group showed significantly higher improvement of respiratory function in terms of maximal inspiratory pressure, maximal expiratory pressure, and forced vital capacity. [Conclusion] These findings showed that children with independent walking ability had better respiratory muscle strength and pulmonary function compared with children without independent walking ability. Understanding respiratory function and the effectiveness of respiratory training according to walking ability will be valuable clinical information for respiratory assessment and therapy in children with CP.
[目的]本研究旨在比较脑瘫（CP）患儿呼吸压力和肺功能的差异以及根据步行能力进行呼吸反馈训练的效果。[对象与方法]23例痉挛型CP患儿纳入最终分析，并分为独立步行组（n = 12）和非独立步行组。所有患儿均接受为期四周的呼吸反馈训练。训练前后，测量呼吸肌力量并进行肺功能测试。[结果]两组之间呼吸压力和肺功能测试结果的比较显示，除呼气峰值流速外，独立步行组在所有变量中的呼吸功能均显著高于另一组。两组呼吸功能变化的比较中，独立步行组在最大吸气压力、最大呼气压力和用力肺活量方面的呼吸功能改善显著更高。[结论]这些结果表明，与无独立步行能力的儿童相比，有独立步行能力的儿童具有更好的呼吸肌力量和肺功能。了解根据步行能力的呼吸功能及呼吸训练效果，将为CP患儿的呼吸评估和治疗提供有价值的临床信息。
