I examined the emergence of automatic postural reactions (righting, equilibrium, and protective reactions) in a group of infants with Down syndrome and in a developmentally matched group of nonhandicapped infants. I assessed the relationship of postural reactions to chronological age and to motor milestone development (as measured by the Bayley Scales of Infant Development). The relationship of postural reactions to chronological age was weaker in the infants with Down syndrome; a regression analysis revealed a slower rate of postural reaction development evident at an age of about five months and older in infants with Down syndrome. The association between postural reactions and motor milestone performance was remarkably similar for both infant groups in degree of association and pattern across the span of motor development tested. The results indicated that, even though the rate of development differed, the association between postural reactions and motor milestones was similar in normal and delayed development. These results support the current rationale that promotes intervention efforts focusing on the facilitation of postural reactions to enhance motor milestone development in infants with Down syndrome.
我研究了一组唐氏综合征婴儿和一组发育匹配的非残疾婴儿中自动姿势反应（翻正、平衡和保护性反应）的出现情况。我评估了姿势反应与实际年龄以及运动里程碑发育（通过贝利婴儿发育量表测量）之间的关系。唐氏综合征婴儿的姿势反应与实际年龄的关系较弱；回归分析显示，唐氏综合征婴儿在大约五个月及以上年龄时，姿势反应发育速度明显较慢。在整个测试的运动发育阶段，两组婴儿的姿势反应与运动里程碑表现之间的关联程度和模式非常相似。结果表明，尽管发育速度不同，但正常发育和发育延迟的婴儿中，姿势反应与运动里程碑之间的关联是相似的。这些结果支持了当前的理论基础，即促进干预措施，重点在于促进姿势反应，以增强唐氏综合征婴儿的运动里程碑发育。
