Implications of the dynamical systems approach to understanding movement dysfunction in infants are discussed. Traditional theories of motor development attribute changes in movement to the hierarchical maturation of the central nervous system. The dynamical systems approach emphasizes that movement self-organizes as the result of the interaction of the participating subsystems in developmental and real time. In this article, I discuss, from the theoretical perspective of the dynamical systems approach, the organization of leg movements in low- and high-risk preterm and full-term infants, developmental changes in movement in low-risk preterm infants from 34 weeks' gestational age to 40 weeks' postgestational age, and differences in movement between low-risk preterm infants at 40 weeks' postgestational age and full-term infants. Preliminary data on high-risk preterm infants are presented. Based on these data, the necessity to review and reinterpret traditional concepts of motor development is explored. Suggestions are offered and questions posed on how the dynamical systems perspective may influence the practice of physical therapy in the evaluation, and treatment of infants at risk for movement dysfunction.
本文讨论了动力系统方法在理解婴儿运动功能障碍方面的意义。传统的运动发育理论将运动变化归因于中枢神经系统的层级成熟。动力系统方法强调,运动是参与子系统在发育过程中和实时相互作用的结果,是自我组织形成的。在本文中,我从动力系统方法的理论视角出发,探讨了低风险和高风险早产儿及足月儿腿部运动的组织方式、低风险早产儿从孕34周到孕龄40周后运动的发育变化,以及孕龄40周后的低风险早产儿与足月儿在运动方面的差异。文中还展示了高风险早产儿的初步数据。基于这些数据,探讨了回顾和重新解释传统运动发育概念的必要性。针对动力系统观点如何影响物理治疗在评估和治疗有运动功能障碍风险婴儿方面的实践,提出了建议并提出了问题。
