    Abstract:
    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. WHAT THIS PAPER ADDS: There is a strong positive relationship between self-care and bimanual performance for unilateral and bilateral cerebral palsy (CP). Both Hands Assessment (BoHA) scores have a stronger association with self-care than Assisting Hand Assessment scores. BoHA scores also account for more variation in self-care. There is a strong positive relationship between self-care and cognition overall. The effect of cognition on self-care performance differed for bilateral and unilateral CP.
