Objective

To obtain reference data on the early motor repertoire of very preterm infants compared with healthy term infants at three months’ post-term age.

Study design

In this observational study, using Prechtl's method on the assessment of the early motor repertoire, we compared the quality of fidgety movements and the concurrent motor optimality score - revised of infants with a gestational age <30 weeks and/or a birth weight <1000 g with healthy infants with a gestational age of 37–42 weeks.

Results

One hundred eighty very preterm and 180 healthy term infants participated. The median motor optimality scores - revised of very preterm infants were significantly lower in comparison to those of term infants, with scores of 24 (25th-75th percentiles: 23–26) and 26 (25th-75th percentiles: 26–28), respectively. Fidgety movements were aberrant (abnormal or absent) more often in very preterm infants than in term infants. The odds ratio was 4.59 (95% CI, 1.51–13.92). Compared with term infants, very preterm infants had poorer scores on the subscales age-adequate movement repertoire, observed postural patterns, and movement character with odds ratios ≥2.97. We found no differences regarding observed movement patterns.

Conclusion

This study provides reference data on the early motor repertoire of very preterm and healthy term infants. It demonstrates that the early motor repertoire of very preterm infants is poorer than that of term infants, a finding consistent with existing knowledge that prematurity increases the risk of poor neurodevelopment.

比较早产儿和足月儿的早期运动功能

客观的

为了获得有关早产儿和早产儿三个月时的健康足月儿的早期运动功能的参考数据。

学习规划

在这项观察性研究中，我们使用Prechtl方法评估早期运动库，我们比较了躁动的质量和同时发生的运动最佳评分-修订了胎龄<30周和/或出生体重<1000 g的婴儿胎龄为37–42周的健康婴儿。

结果

一百八十个极早产婴儿和180个健康足月婴儿参加了研究。与早产儿相比，极早产儿的运动最佳中位分数（修订版）明显低于足月儿，分别为24（25-75％：23-26）和26（25-75％：26-28）。 。与早产儿相比，早产儿的坐立不安运动异常（异常或缺乏）更多。优势比为4.59（95％CI，1.51–13.92）。与足月儿相比，极早产儿在年龄足够的运动能力表中得分较低，观察到的姿势模式和运动特征比值比≥2.97。我们发现观察到的运动模式没有差异。

结论

该研究为早产和健康足月儿的早期运动功能提供参考数据。它表明，早产儿的早期运动功能比足月儿差，这一发现与早产会增加不良神经发育风险的现有知识相一致。
