DESCRIPTION (provided by applicant): One of the major challenges of motor control is understanding how the central nervous system controls the degrees of freedom of the human body. Postural control of the trunk is essential for all other motor tasks. This foundational motor task is typically accomplished by 9 to 10 months of age when infants are able to sit independently. From that age on the spine is so well controlled that it is acceptable in posture control research to consider the trunk as one segment. Surprisingly little is known about how infants learn to control multiple segments of the spine. In this proposal, a novel approach allows evaluation of limited segments of the spine allowing measurement of upright postural control prior to the development of independent sitting. I will evaluate development of spinal control in a longitudinal study of infants from 3 months to 9 months of age and compare EMG and kinematic data from this group with data obtained from children with cerebral palsy who have been unable to achieve independent sitting balance. This knowledge will allow clinicians to develop new methods of training and evaluation and new types of supportive devices. The technique will also enhance the potential for research on development of motor control of the trunk.

描述（由申请人提供）：运动控制的主要挑战之一是了解中枢神经系统如何控制人体自由度。行李箱的姿势控制对于所有其他运动任务都是必不可少的。该基础运动任务通常是在婴儿能够独立坐下的9至10个月大的时间内完成的。从那个年龄开始，脊柱的控制良好，以至于可以将躯干视为一个细分市场，在姿势控制研究中是可以接受的。令人惊讶的是，关于婴儿如何学习控制脊柱的多个段的知之甚少。在此提案中，一种新颖的方法允许评估有限的脊柱段，可以在开发独立坐姿之前对直立的姿势控制进行测量。我将评估从3个月到9个月大的婴儿的纵向研究中的脊柱控制发展，并比较该组的EMG和运动学数据与无法实现独立坐余平衡的脑瘫儿童获得的数据。这些知识将使临床医生能够开发新的培训和评估方法以及新型的支持设备。该技术还将增强研究躯干运动控制发展的潜力。
