运动行为的复杂性是健康系统的标志。本研究的目的是在两种情况下探讨早期运动行为发展过程中的姿势复杂性。22名1至6个月大的婴儿参与了这项研究。采用支撑底部压力中心的线性和非线性位移测量来量化姿态控制的大小和时间结构。行为编码用于量化中线头部控制和早期到达的出现。结果表明，婴儿在发育早期具有姿势控制策略的复杂性。这种复杂性随着婴儿学习运动行为而降低，即使姿势可变性的大小没有改变。婴儿能够适应不同条件下的姿势控制变异性的大小。我们认为婴儿经历了三个阶段来支持婴儿适应运动行为的能力。(c) 2012 Wiley期刊有限公司中国生物医学工程学报，2013,31 (5):444 - 444
Complexity in motor behavior is a hallmark of healthy systems. The purpose of this study was to investigate postural complexity during development of early motor behaviors and under two conditions. Twenty-two infants participated from 1 to 6 months of age. Linear and nonlinear measures of displacement of the center of pressure at the base of support were used to quantify magnitude and temporal structure of postural control. Behavioral coding was used to quantify the emergence of midline head control and early reaching. Results suggest that infants have complexity in postural control strategies early in development. This complexity decreases as infants learn motor behaviors, even when magnitude of the postural variability does not change. Infants were able to adapt the magnitude of postural control variability under different conditions. We propose that infants proceed through three stages which support the infant's ability to adapt motor behaviors. (c) 2012 Wiley Periodicals, Inc. Dev Psychobiol 55: 404414, 2013
