Although trunk muscles extend across multiple vertebral joints, recent motor control studies have shown that a top-down progression of trunk control in typical infants occurs incrementally, one segment at a time, until independent sitting. The current study merges this surprising developmental pattern with parent behavior by exploring the relationship between how parents hold their infant and the segmental level for which the infant exhibits postural control. We measured trunk control of 60 infants (1-8 months) via the segmental assessment of trunk control. Spontaneous parental hold and variability was recorded during repeated sitting and standing conditions. Parent hold correlated with infant level of control in both sitting and standing, providing evidence for a positive interaction between parent behavior and segmental trunk development.
尽管躯干肌肉跨越多个椎骨关节，但最近的运动控制研究表明，典型婴儿的躯干控制是自上而下逐步进行的，一次一个节段，直到能够独立坐立。本研究通过探讨父母抱婴儿的方式与婴儿表现出姿势控制的节段水平之间的关系，将这一惊人的发育模式与父母行为相结合。我们通过对60名1至8个月大婴儿的躯干控制进行节段评估来测量其躯干控制能力。在反复坐立和站立的情况下，记录父母自然的抱姿及其变化。父母的抱姿与婴儿在坐立和站立时的控制水平相关，这为父母行为与躯干节段发育之间的积极相互作用提供了证据。
