Sensory-motor performance in seven-year-old children born extremely preterm.

Children born preterm are prone to motor problems. Research on their motor performance has, however, rarely been integrated with sensory processing.To examine sensory-motor performance in children born extremely preterm (EPT).In a longitudinal prospective cohort study, 49 EPT (born <28 gestational weeks; 32 boys and 17 girls) and 33 term-born (16 boys and 17 girls) children were assessed with six individual subtests from the Sensory Integration and Praxis Tests at the age of 7.0 to 7.3 years.The rate of test z-scores indicating dysfunction [from -2 standard deviations (SD) to < -1 SD for mild and < -2 SD for moderate-to-severe] was significantly higher in EPT children than in term-born children in all the subtests. When comparing mean performance adjusted for gender and mother's education, EPT children performed worse than term-born children in Design Copying (z-score difference - 0.83; 95% confidence interval -1.32 to -0.34), Motor Accuracy (-0.82; -1.26 to -0.38), Postural Praxis (-0.95; -1.45 to -0.45), Manual Form Perception (-0.59; -1.12 to -0.06), and Finger Identification (-0.88; -1.45 to -0.31). Additional adjustment for Full-Scale Intelligence Quotient rendered difference in Manual Form Perception non-significant.Seven-year-old EPT children perform worse than their term-born peers in tests for visual-motor, somatosensory, and motor planning performance.Copyright © 2018 Elsevier B.V.
