Objectives: To explore the relations between cognitive performance and spatio-temporal organization of upper-body movements in preterm children at school age compared with full-term peers.
Background: Neuromotor disabilities and lowered cognitive performance are frequently reported in school-aged preterm children. A few studies have also reported associations between intelligence and motor skill outcomes in this population as assessed by standardized test batteries. At present, however, there is no knowledge of how measures of intelligence relate to more refined measurements of movement quality in preterm children.
Design/Method: In the present study, performance on the Wechsler Intelligence Scale for Children, 4th edition (WISC-IV) was related to optoelectronic registrations (ProReflex, Qualisys Inc.) of arm movement performance during a unimanual precision task in a sample of preterm children at 6 to 8 years (n=31) compared with typically developing full-term children (n=36).
Results: A significant group effect was revealed for Fullscale IQ, indicating poorer overall performance on the WISC-IV by preterm (mean 95.1) than full-term (mean 103.5) participants. The same pattern was apparent for both the Verbal and Performance indexes and the majority of the sub-tests. Correlation analyses were performed to test the associations between cognitive performance and spatiotemporal movement parameters. Several findings emerged from this procedure and will be presented, including significant relations between Full-scale IQ and movement segmentation at both the proximal and distal level in preterm but not full-term participants.
Conclusions: Measures of WISC-IV appear significantly associated with kinematic outcome measures in schoolaged preterm children in terms of better cognitive performance being linked with better movement organization. The same associations were not seen in the age- and sexmatched full-term group. This type of investigation adds to the understanding of relations between cognitive and motor performance in the context of movement organization, coordination, and control depending on birth history.
