婴儿获得从仰卧位到俯卧位的翻身能力，这需要在与地面的动态相互作用下的多个自由度的身体协调。虽然以前的研究婴儿滚动观察到的运动学特征，很少有人知道的动力学特征的身体部分与表面接触。我们测量了地面接触压力下的手臂，腿，头，和近端的身体部分使用压力垫和他们的位移使用三维运动捕捉系统。17例9-10个月婴儿的数据表明，大多数婴儿表现出6种高度观察的运动模式中的2-4种，包括1种轴向滚动模式、2种脊柱屈曲模式和3种肩带引导模式。在轴向滚动和脊柱屈曲模式中，手臂和腿对地面接触压力的贡献很小。与滚转方向有关的同侧腿仅在1个肩带引导模式中参与支撑体重。对侧腿在3个肩胛带引导模式中滚动之前在地板上显示出大的峰值压力。结果表明，婴儿可以产生多种翻身模式与不同的策略，以协调他们的身体部分和与地板的互动。运动模式的分析结果进一步表明，很少有模式对应于成人报告的模式。这意味着婴儿通过考虑自己的生物力学约束来产生独特的运动模式。
Infants acquire the ability to roll over from the supine to the prone position, which requires body coordination of multiple degrees of freedom under dynamic interactions with the ground. Although previous studies on infant rolling observed kinematic characteristics, little is known about the kinetic characteristics of body segments in contact with the surface. We measured the ground contact pressure under the arms, legs, head, and proximal body segments using a pressure mat and their displacements using a three-dimensional motion capture system. The data obtained from 17 infants aged 9–10 months indicated that most of them showed 2–4 of 6 highly observed movement patterns, including 1 axial rolling, 2 spinal flexion, and 3 shoulder girdle leading patterns. The arms and legs had small contributions to the ground contact pressure in the axial rolling and spinal flexion patterns. The ipsilateral leg in relation to the rolling direction was involved in supporting the body weight in only 1 shoulder girdle leading pattern. The contralateral leg showed large peak pressure to push on the floor before rolling in 3 shoulder girdle leading patterns. The results indicate that infants can produce multiple rolling-over patterns with different strategies to coordinate their body segments and interact with the floor. The results of the analysis of the movement patterns further suggest that few patterns correspond to those reported in adults. This implies that infants generate unique motor patterns by taking into account their own biomechanical constraints.
