AIM To examine the relationship between self-care and bimanual performance in children aged 8 to 12 years with cerebral palsy (CP). METHOD This was a cross-sectional study of 74 children with CP (unilateral n=30, bilateral n=44; 48 males, 26 females; median age 9y 8mo [25th, 75th centiles 9y 1mo, 10y 8mo], Manual Abilities Classification System level I=30, II=28, III=16). Self-care was measured using the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT), and bimanual performance using the Assisting Hand Assessment (AHA) and Both Hands Assessment (BoHA). Measures of cognition, behavioural regulation, inattention, and gross motor function were included. Analyses used a directed acyclic graph to select variables for linear regression modelling. RESULTS Higher AHA and BoHA scores were associated with higher PEDI-CAT scores. An increase of 1 AHA unit was associated with an increase of 0.12 PEDI-CAT scores, and a 1 BoHA unit increase was associated with an increase of 0.17 PEDI-CAT scores. The BoHA accounted for 57% of variance in PEDI-CAT scores for children with bilateral CP, while BoHA and cognition accounted for 68% of variance. The AHA accounted for 40% of variance in PEDI-CAT scores for unilateral CP with no effect of cognition on self-care. INTERPRETATION Self-care was strongly and positively associated with bimanual performance. Associations between self-care and bimanual performance differed for those with unilateral and bilateral CP.

脑瘫患儿的手功能与自我保健

目的 探讨 8～12 岁脑瘫（CP）儿童自理能力与双手合力的关系。方法 这是一项对 74 名 CP 儿童的横断面研究（单侧 n=30，双侧 n=44；48 名男性，26 名女性；中位年龄 9 岁 8 个月 [25，第 75 个百分位数 9 岁 1 个月，10 岁 8 个月]，手动能力分类系统级别 I=30，II=28，III=16）。使用残疾清单的儿科评估 - 计算机适应性测试 (PEDI-CAT) 测量自我护理，并使用辅助手评估 (AHA) 和双手评估 (BoHA) 测量双手表现。包括认知、行为调节、注意力不集中和粗大运动功能的测量。分析使用有向无环图来选择用于线性回归建模的变量。结果 较高的 AHA 和 BoHA 分数与较高的 PEDI-CAT 分数相关。增加 1 个 AHA 单位与增加 0.12 个 PEDI-CAT 分数相关，增加 1 个 BoHA 单位与增加 0.17 个 PEDI-CAT 分数相关。BoHA 占双侧 CP 儿童 PEDI-CAT 评分方差的 57%，而 BoHA 和认知占方差的 68%。AHA 占单侧 CP 的 PEDI-CAT 分数方差的 40%，认知对自我护理没有影响。解释 自我照顾与双手表现强烈且正相关。对于单侧和双侧 CP 患者，自我护理和双手表现之间的关联不同。BoHA 占双侧 CP 儿童 PEDI-CAT 评分方差的 57%，而 BoHA 和认知占方差的 68%。AHA 占单侧 CP 的 PEDI-CAT 分数方差的 40%，认知对自我护理没有影响。解释 自我照顾与双手表现强烈且正相关。对于单侧和双侧 CP 患者，自我护理和双手表现之间的关联不同。BoHA 占双侧 CP 儿童 PEDI-CAT 评分方差的 57%，而 BoHA 和认知占方差的 68%。AHA 占单侧 CP 的 PEDI-CAT 分数方差的 40%，认知对自我护理没有影响。解释 自我照顾与双手表现强烈且正相关。对于单侧和双侧 CP 患者，自我护理和双手表现之间的关联不同。
