Abstract

AIM: We aimed to clarify the underpinnings of widespread visuomotor deficits in very preterm children.

METHOD: Fifty-eight very preterm children (26 males, 32 females; mean [SD] age 7 y 6 mo [5 mo], gestational age 29.2 wks [1.6]; birthweight 1237 g [336]), recruited from a tertiary level neonatal intensive care unit, and 64 age-matched, comparison children born at term (28 males, 36 females; mean age [SD] 7 y 8 mo [7 mo]) participated. IQ was measured using a short form of the Wechsler Intelligence Scale for Children (3rd edition). A research diagnosis of developmental coordination disorder (DCD) was defined as a score below the 15th centile on the Movement Assessment Battery for Children. Visuomotor performance was assessed using a computerized task, in which children followed a predictable (structured condition) or an unpredictable (non-structured condition) trail on a touch screen using their index finger.

RESULTS: Forty-six per cent of the very preterm children had a research diagnosis of DCD, compared with 16% of children born at term (p<0.001, odds ratio 4.69 [95% CI 2.01-10.99]). No group difference in visuomotor performance was present for the structured condition. In the non-structured condition, children born very preterm with and without a research diagnosis of DCD had poorer visuomotor performance than those born at term.

INTERPRETATION: The predictability of the required motor response plays a crucial role in visuomotor deficits in very preterm children, regardless of DCD status.
