The aim of this study was to better understand the mechanisms underlying the motor difficulties encountered by children born very preterm (VPT) without major sequelae from preterm birth. We compared the organization of visuo-manual aiming in preterm and full term (FT) preschool aged children based on performance and kinematics data. Twenty preterm (4 females, 16 males) and 20 sex- and age-matched FT children were divided into two age groups (mean age: 3 years-4 months, and 5 years). Comparison of the performance data showed differences between the older preterm and FT children. Kinematics data revealed differences in movement control between the younger preterm and FT children. The younger FT children did not differ from the older children. In addition, there was an effect of age on both performance and kinematics data for the preterm children only. The pattern of results suggests difficulties in integrating sensory information for movement control in the preterm groups, leading to a delay in the development of visuo-manual coordination. Kinematics analyses may help identify children at risk for poor school performance.
本研究的目的是更好地理解极早产儿（VPT）在无早产主要后遗症情况下出现运动困难的潜在机制。我们基于表现和运动学数据，比较了早产和足月（FT）学龄前儿童的视觉-手动瞄准组织情况。20名早产儿（4名女性，16名男性）和20名性别与年龄匹配的足月儿被分为两个年龄组（平均年龄：3岁4个月和5岁）。表现数据的比较显示，年龄较大的早产儿和足月儿之间存在差异。运动学数据揭示了年龄较小的早产儿和足月儿在运动控制方面的差异。年龄较小的足月儿与年龄较大的儿童没有差异。此外，仅在早产儿的表现和运动学数据方面存在年龄效应。结果模式表明，早产组在整合用于运动控制的感觉信息方面存在困难，导致视觉-手动协调发展延迟。运动学分析可能有助于识别学业成绩不佳风险的儿童。
