Cognitive outcome shown in 11-year-old children born very preterm with CP and according to the performance in the Movement Assessment Battery for Children in children without CP
| CP, n=9 | DCD, ≤5th percentile, n=18 | Children without motor impairment, >5th percentile, n=142 | P value | |
| Full-Scale IQ | 62.4 (22.8) (40.0, 97.0) | 76.8 (18.2) (40.0, 100.0) | 91.6 (14.3) (52.0, 131.0) | <0.001* |
| Verbal comprehension | 75.1 (21.1) (46.0, 98.0) | 83.8 (16.3) (46.0, 108.0) | 92.1 (13.4) (60.0, 122.0) | 0.02* |
| Perceptual reasoning | 64.8 (23.1) (40.0, 100.0) | 85.7 (17.9) (51.0, 109.0) | 94.8 (14.6) (62.0, 122.0) | 0.02* |
| Working memory | 77.0 (20.5) (46.0, 109.0) | 79.2 (13.9) (46.0, 97.0) | 95.4 (15.0) (55.0, 133.0) | <0.001* |
| Processing speed | 72.4 (21.4) (47.0, 106.0) | 83.3 (19.4) (47.0, 118.0) | 96.5 (15.5) (56.0, 153.0) | 0.001* |
The mean values (SD) (minimum, maximum) of Full-Scale IQ and its four indexes are shown.
The outcomes are compared between children with DCD and children without motor impairment (two-sample t-test).
*The results remained statistically significant after adjusting for birth weight, gestational age, and mother’s and father’s education.
CP, cerebral palsy; DCD, developmental coordination disorder.
