Visuospatial perception in children born preterm with no major neurological disorders.

Objective: Many investigations have found deficits in visuospatial perception in children born preterm, however, it is not clear whether the deficits are specific to visuospatial perception or the consequences of deficits in other functional areas, which often accompany preterm birth. This study investigated whether children born preterm show a specific deficit in visuospatial perception.

Method: Fifty-six 7- to 11-year-old preterm born children (gestational age <34 weeks) without cerebral palsy and 51 age-matched, full-term children completed four computerized tasks tapping different levels and types of visuospatial perception.

The quality of preterm infants' spontaneous movements: an early indicator of intelligence and behaviour at school age.

Background: The quality of very preterm infants' spontaneous movements at 11 to 16 weeks post-term age is a powerful predictor of their later neurological status. This study investigated whether early spontaneous movements also have predictive value for the intellectual and behavioural problems that children born very preterm often experience.

Methods: Spontaneous movement quality was assessed, using Prechtl's method, at 11 to 16 weeks post-term in 65 infants born at View Article and Find Full Text PDF

Quantitative aspects of the early motor repertoire in preterm infants: do they predict minor neurological dysfunction at school age?

Background: Qualitative aspects of the motor repertoire, at 11-16 weeks post-term are predictive for minor neurological dysfunction (MND) at 7 to 11 years of age. Predictive value of quantitative aspects is unknown so far.

Aim: To investigate whether quantitative aspects of the motor repertoire between 6 and 24 weeks post-term also have predictive value for neurological outcome at 7 to 11 years of age.

Movement adaptations in 7- to 10-year-old typically developing children: evidence for a transition in feedback-based motor control.

We used a modified double-step pointing task to study movement adaptations in 7- to 10-year-old typically developing children. We found that the majority (63%) were able to optimally adapt fast, goal-directed visually-guided movements to a late change in target location meeting the requirements of speed and accuracy. A minority (35%) failed to meet the requirement of accuracy resulting in a less optimal adaptation.

Quality of general movements and the development of minor neurological dysfunction at toddler and school age.

Objective: To evaluate the reliability of assessing infants' general movements (GMs) using a new classification and its validity in predicting complex minor neurological dysfunction (MND) at toddler and at school age.

Design: Prospective study of two groups of infants, each consisting of a mix of low-risk and high-risk infants.

Setting: University Hospital Groningen, the Netherlands.

Maternal rigidity in infancy and level of intelligence at school age in children born preterm.

Forty-four children who had been born preterm and their mothers participated in the follow-up study. At 3 and 14 months (corrected age) cognitive development was assessed using the BOS 2-30, the Dutch version of the Bayley Scales of Infant Development. The BOS yields measures of mental and motor development.
