感知和行动之间的协调是与环境成功互动的必要条件。这已经被非常年幼的婴儿训练过了，他们进行自发的运动来学习他们的身体如何与环境相互作用。婴儿为此目的使用的策略会随着年龄的增长而变化。因此，可以通过监测婴儿自发运动活动的发展来研究婴儿在动作控制方面取得的非常早期的进展。本文介绍了一种可以定量评价新生儿自发活动发育的客观方法。所介绍的方法基于通过3D运动分析获取脚的自发运动轨迹，并随后从这些运动中计算特定的运动参数。有了这些基于运动的参数，就有可能客观地描述小于6个月的健康新生儿的年龄相关发育阶段。此外，研究还表明，像婴儿脑瘫这样的疾病对运动能力的发展有很大影响。由于引入的方法是客观和定量的，因此适合监测新生儿是如何训练他们的认知过程的，这将使他们能够通过运动交互来应对环境。
Coordination between perception and action is required to interact with the environment successfully. This is already trained by very young infants who perform spontaneous movements to learn how their body interacts with the environment. The strategies used by the infants for this purpose change with age. Therefore, very early progresses in action control made by the infants can be investigated by monitoring the development of spontaneous motor activity. In this paper, an objective method is introduced, which allows the quantitative evaluation of the development of spontaneous motor activity in newborns. The introduced methodology is based on the acquisition of spontaneous movement trajectories of the feet by 3D movement analysis and subsequent calculation of specific movement parameters from them. With these movement-based parameters, it was possible to provide an objective description of age-dependent developmental steps in healthy newborns younger than 6 months. Furthermore, it has been shown that pathologies like infantile cerebral palsy influence development of motor activity significantly. Since the introduced methodology is objective and quantitative, it is suitable to monitor how newborns train their cognitive processes, which will enable them to cope with their environment by motor interaction.
