ABSTRACT Children with cerebral palsy (CP) are likely to experience decreased participation in activities and less competence in activities of daily living. Studies of children with spastic CP have shown that strengthening programs produce positive results in strength, gait, and functional outcomes (measured by the Gross Motor Function Measure). No investigations have analyzed electromyography (EMG) activity before and after strength training to determine whether any changes occur in the GMFM. This feasibility case report quantified dorsiflexor and plantarflexor muscle activation changes during performance of 3-5 selected GMFM items following a plantarflexor strength training in two children with cerebral palsy. Increased plantarflexor strength and increased ability to selectively activate muscles were found. Little carryover to performance on GMFM items was observed. It is feasible to use EMG during performance on selected GMFM items to evaluate motor control changes following strength training in children with CP.
脑瘫儿童（CP）可能会经历活动参与度降低和日常生活活动能力下降。对痉挛型 CP 儿童的研究表明，强化计划在力量、步态和功能结果（通过粗大运动功能测量法测量）方面产生了积极的结果。没有研究分析力量训练前后的肌电图（EMG）活动，以确定 GMFM 是否发生任何变化。本可行性病例报告量化了两名脑瘫儿童进行跖屈肌力量训练后，在执行 3-5 项 GMFM 选定项目期间，背屈肌和跖屈肌肌肉激活的变化。发现跖屈肌力量增加，选择性激活肌肉的能力增强。在 GMFM 项目上的表现几乎没有延续。在 CP 儿童进行选定的 GMFM 项目时使用肌电图来评估力量训练后运动控制的变化是可行的。
