婴儿坐姿摇摆为幼儿时期的运动发育提供了一个窗口。姿势摇摆中的近似熵（随机性的度量）被用来评估发育迟缓，如脑瘫中发生的情况。对用于计算近似熵的参数进行了研究，发现对于前后轴发育迟缓的婴儿，早期坐姿姿势摇摆的近似熵较低，但对于内外轴发育迟缓的婴儿则较低。频谱分析显示，典型发育的婴儿早期坐姿的姿势摇摆具有更高的频率特征，这表明与发育迟缓的婴儿相比，典型发育的婴儿有更快的控制机制活跃，可能是由接近跌倒事件激活的。
Infant sitting postural sway provides a window into motor development at an early age. The approximate entropy, a measure of randomness, in the postural sway was used to assess developmental delay, as occurs in cerebral palsy. Parameters used for the calculation of approximate entropy were investigated, and approximate entropy of postural sway in early sitting was found to be lower for infants with developmental delay in the anterior-posterior axis, but not in the medial-lateral axis. Spectral analysis showed higher frequency features in the postural sway of early sitting of infants with typical development, suggesting a faster control mechanism is active in infants with typical development as compared to infants with delayed development, perhaps activated by near-fall events.
