Abstract |
Objectives |
To determine associations between hand function at age 18-22 months (early) and scores on the Movement Assessment Battery for Children, 2nd edition (MABC) at 6-7 years of age (school age) in extremely preterm children.
Study design |
Prospective multicenter cohort of 313 extremely preterm children with early hand function assessment and school-age MABC testing. Early hand function was compared with “definite deficits” (MABC <5th percentile) and MABC standard scores. Early hand function was categorized as “no deficit” vs “any deficit.” Mixed-effects regression models were used to evaluate the association of early hand function with MABC deficits, controlling for multiple demographic, neonatal, and childhood factors.
Results |
Children with early hand function deficits were more likely to have definite school-age deficits in all MABC subtests (Manual Dexterity, Aiming and Catching, and Balance) and to have received physical or occupational therapy (45% vs 26%; P < .001). Children with early hand function deficits had lower Manual Dexterity (P = .006), Balance (P = .035), and Total Test (P = .039) scores. Controlling for confounders, children with early hand function deficits had higher odds of definite school-age deficits in Manual Dexterity (aOR, 2.78; 95% CI, 1.36-5.68; P = .005) and lower Manual Dexterity (P = .031) and Balance (P = .027) scores. When excluding children with cerebral palsy and those with an IQ <70, hand function deficits remained significantly associated with manual dexterity.
Conclusion |
Hand function deficits at age 18-22 months are associated with manual dexterity deficits and motor difficulties at school age, independent of perinatal-neonatal factors and the use of occupational or physical therapy. This has significant implications for school success, intervention, and rehabilitative therapy development.
