To investigate the relations between changes in motor capacity (can do, in standardized environment), motor capability (can do, in daily environment), and motor performance (does do, in daily environment) among children with cerebral palsy (CP).
Prospective longitudinal study. After baseline measurements (at the age of 18 mo, 30 mo, 5 y, 7 y, 9 y, 11 y, or 13 y), 2-year follow-up measurements were performed. Change scores were calculated, and Pearson correlations were used for change score relations.
Outpatient clinic.
Toddlers, school-age children, and adolescents with CP (N=321; 200 boys, 121 girls). Levels of severity according to the Gross Motor Function Classification System included level I (42%), level II (15%), level III (17%), level IV (13%), and level V (13%).
Not applicable.
Change in motor capacity was assessed with the Gross Motor Function Measure-66. Changes in motor capability and motor performance were assessed with the Pediatric Evaluation of Disability Inventory using the Functional Skills Scale and Caregiver Assistance Scale, respectively.
Within the total group, change score correlations were moderate (.52-.67) and significant (P<.001). For age groups, correlations were significantly higher in toddlers than school-age children and adolescents. For severity levels, correlations were significantly higher in children at level III than level I, IV, and V.
Results imply that change in motor capacity does not automatically translate to change in motor capability and change in motor capability does not automatically translate to change in motor performance. Results also show different relations for clinically relevant subgroups. These are important insights for clinical practice because they can guide evidence-based interventions with a focus on activities.
研究脑瘫儿童的运动能力（在标准化环境中能做什么）、运动能力（在日常生活环境中能做什么）和运动表现（在日常生活环境中实际做什么）的变化之间的关系。
前瞻性纵向研究。在基线测量（18 个月、30 个月、5 岁、7 岁、9 岁、11 岁或 13 岁时）后，进行了为期 2 年的随访测量。计算变化分数，并使用 Pearson 相关系数来评估变化分数之间的关系。
门诊。
脑瘫儿童（N=321；男孩 200 名，女孩 121 名）。根据粗大运动功能分类系统，严重程度水平包括 I 级（42%）、II 级（15%）、III 级（17%）、IV 级（13%）和 V 级（13%）。
无。
使用粗大运动功能测量-66 评估运动能力的变化。使用小儿残疾评估量表的功能技能量表和照顾者协助量表分别评估运动能力和运动表现的变化。
在总组中，变化分数之间的相关性为中等（.52-.67）且显著（P<.001）。对于年龄组，幼儿的相关性明显高于学龄儿童和青少年。对于严重程度水平，III 级儿童的相关性明显高于 I 级、IV 级和 V 级儿童。
结果表明，运动能力的变化不一定会自动转化为运动能力的变化，运动能力的变化也不一定会自动转化为运动表现的变化。结果还显示了对具有临床意义的亚组的不同关系。这些结果对临床实践很重要，因为它们可以指导以活动为重点的循证干预。
