Abstract

BACKGROUND

Children born preterm are prone to motor problems. Research on their motor performance has, however, rarely been integrated with sensory processing.

AIM

To examine sensory-motor performance in children born extremely preterm (EPT).

METHOD

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.

RESULTS

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.

CONCLUSION

Seven-year-old EPT children perform worse than their term-born peers in tests for visual-motor, somatosensory, and motor planning performance.

摘要

背景

早产出生的儿童容易出现运动问题。然而，对他们运动表现的研究很少与感觉加工相结合。

目的

研究极早早产儿（EPT）的感觉运动表现。

方法

在一项纵向前瞻性队列研究中，对49名极早早产儿（孕周<28周；32名男孩和17名女孩）和33名足月儿（16名男孩和17名女孩）在7.0至7.3岁时进行了感觉统合与实践测试中的六项个体子测试。

结果

在所有子测试中，表明功能障碍的测试z分数率（轻度为-2标准差（SD）至<-1 SD，中度至重度为<-2 SD）在极早早产儿中显著高于足月儿。在对性别和母亲教育程度进行调整后比较平均表现时，极早早产儿在图案临摹（z分数差异-0.83；95%置信区间-1.32至-0.34）、运动准确性（-0.82；-1.26至-0.38）、姿势实践（-0.95；-1.45至-0.45）、手部形状感知（-0.59；-1.12至-0.06）和手指识别（-0.88；-1.45至-0.31）方面的表现比足月儿差。对全量表智商进行额外调整后，手部形状感知的差异不显著。
