STRATEGIES FOR ANALYZING INFANT AND TODDLER MOVEMENT

这个项目的长期目标是更好地了解婴儿 以及学步儿童的运动发育。具体目标包括发展和 验证分析运动行为的新策略，重点是 运动的质量。 移动质量将被操作为：1)在 位置，2)位置内的过渡，3)复杂的组合 单个运动事件，以及4)异常运动模式的数量。 样本将是390名正常儿童和90名高危儿童。分析将 重点确定标准运动模式、发育年龄趋势、 高危/正常组差异大，可靠性高。 与传统的运动评估方法不同，拟议的观察 系统在自发、自然的背景下评估运动- 正在上演的戏剧。汽车评估，涉及直接处理 孩子一直被发现是不可靠的。新方法 最大限度地减少考官与考生互动的非受控影响 因为几乎不需要处理。 负责任地实施公法99-457要求可靠和 适用于婴幼儿的有效观察技术。这个 拟议的研究在理论和临床上都有意义，并可能 在评估运动发育和预测风险方面有价值。

The long-term objective of this project is a better understanding of infant and toddler motor development. Specific aims include the development and validation of new strategies for analyzing motor behavior with emphasis on quality of movement. Quality of movement will be operationalized as: 1) variations within a position, 2) transitions within a position, 3) complex combinations of single motor events, and 4) the number of abnormal movement patterns. The sample will be 390 normal and 90 high-risk children. Analyses will focus on determining normative motor patterns, developmental age trends, high-risk/normal group differences, and reliability. Unlike traditional approaches to motor assessment, the proposed observation system evaluates movement in the context of spontaneous, naturally- occurring play. Motor assessments that involve direct handling of the child have consistently been found to be unreliable. The new approach minimizes the uncontrolled-for effects of examiner-examinee interactions because little handling is required. The responsible implementation of Public Law 99-457 demands reliable and valid observational techniques for use with infants and toddlers. The proposed research is theoretically and clinically meaningful and likely to be of value in evaluating motor development and predicting risk.
