项目摘要
Project Summary
Infants with developmental delay often experience lifelong difficulties in motor, cognitive and
social skills. A challenge to providing early physical therapy intervention, however, is that it can
be difficult to identify atypical development within the first few months of life due to infants’
limited motor skills and highly variable rates of development and motor skill performance. The
aim of this study is to use electroencephalography (EEG) to obtain a neural measure of the
development of infant motor control in infants at risk for developmental delay. EEG is a neural
imaging technique that non-invasively measures brain activity and has great potential for
measuring brain function related to infant motor control. Combining EEG with observation of
infant movements will support better identification of infants who will benefit from early therapy
intervention.
This is a longitudinal, observational study of infants at risk for developmental delay 3-6 months
of age. EEG data will be collected monthly as infants learn to reach for objects. EEG measures
of interest are amount of activity in (power) and connections (coherence) between parts of the
brain involved in executive attention and intention (frontal cortex), motor control (motor cortex),
and sensory integration (parietal cortex). The first aim of this project is to determine the
developmental trajectory of changes in EEG measures of neuromotor control as infant reaching
skills develop in infants at risk for developmental delay. The second aim of this project is to
relate EEG measures to behavioral and functional measures of infant neuromotor control.
Achieving our overall objective will provide a much-needed neural biomarker of the development
of infant neuromotor control in infants at risk for developmental delay. Results of this study will
provide the crucial first step in our effort to evaluate the effectiveness of therapeutic intervention
aimed at improving neuromotor development for infants with or at risk for developmental delay
and other neuromotor problems. Optimal early intervention will support the Eunice Kennedy
Shriver National Institute of Child Health and Human Development mission that all children have
the chance to achieve their full potential for healthy and productive lives, free from disease or
disability, and to ensure the health, productivity, independence, and well-being of all people
through optimal rehabilitation. This research also fits with the mission of the National Institutes
of Neurological Disorders and Stroke: to seek fundamental knowledge about the brain and
nervous system and to use that knowledge to reduce the burden of neurological disease.
项目总结:
--
患有发育迟缓的婴儿通常会在运动、认知能力和智力方面经历终生的困难。
社交技能。我们面临的挑战是如何提供早期的物理治疗和干预,然而,它不可能做到这一点。
由于婴儿的死亡,很难在生命的头几个月内识别出不典型的婴儿发育不良。
有限的运动技能,以及高度可变的运动发展速度和运动技能表现。
本研究的目的是使用脑电图仪(EEG)来获得患者的一项重要的神经功能测量指标。
婴儿运动控制能力的发育迟缓是婴儿发育迟缓的危险因素。
成像技术是一种非侵入性的测量大脑活动的技术,具有巨大的应用潜力。
脑功能测定与婴幼儿运动功能控制有关。脑电图仪与儿童观察法相结合。
婴儿运动将支持对婴儿进行更好的识别,因为他们将从早期婴儿治疗中受益。
干预。

这项研究是对有发育迟缓3-6个月风险的婴儿进行的一项纵向、观察性的研究。
到了这个年龄,将不再每月收集一次脑电数据,因为婴儿可以学习如何接触不同的物体。
最令人感兴趣的是网络(电源)中的活动数量以及设备各部分之间的连接(一致性)。
大脑参与了执行注意和意向控制(额叶皮质),以及运动控制(运动和皮层)。
以及感觉和大脑皮质的整合(顶叶皮质)。这是这一项目的第一个目标,它被认为是不确定的。
随着婴儿发育成熟,脑电图仪测量神经运动控制能力变化的发展轨迹。
在婴儿发育迟缓的风险下发展他们的技能。这一项目的第二个主要目标是:
涉及到EEG的措施,包括婴儿的行为控制和神经运动控制的功能控制。
实现我们的总体目标也将为我们提供一个亟需的神经和生物标记物来促进我们的发展。
在面临发育迟缓风险的婴儿中,有6%的婴儿存在神经运动控制障碍。这项研究的结果将公布。
为我们进一步评估治疗性医疗干预的有效性提供关键的第一步。
旨在改善患有发育迟缓或有发育迟缓风险的婴儿的神经运动发育能力。
以及其他神经运动问题。一个最优的早期医疗干预计划将继续支持美国总统肯尼迪。
施莱弗是美国儿童健康研究所和世界人类发展基金会的使团,他们表示,所有儿童都已经患上了艾滋病。
最大的机会是充分发挥他们的潜力,为人们提供健康的生活和高效的生活,使他们远离疾病或疾病。
残疾、残疾和残疾,以确保所有中国人的身体健康、生产力、独立性和福祉。
通过最优的医疗康复,这一研究成果也非常契合美国国立卫生研究院的使命目标。
神经功能障碍和中风的研究:寻求有关大脑功能和功能的基础知识
紧张的神经系统需要更多地利用这些知识来进一步减轻神经系统疾病的负担。
