Project Summary Children who are born preterm are at a high risk for developing sensorimotor deficits. Though a majority of children born preterm do not have a neuromuscular diagnosis such as cerebral palsy, many have mild to moderate motor delays. These motor delays fall under the diagnosis of developmental coordination disorder or developmental dyspraxia, a condition with difficulties in motor planning and coordination, that is theoretically linked to somatosensory deficits. We hypothesize that deficit in somatosensory processing may precede this diagnosis in preterm children, but these deficits are not identified due to a lack of reliable and valid assessment methods for use with young children. Somatic sensations refer to sensory information from the body, including touch and proprioception. Proprioception -- the sense that lets us know how and where our body is moving -- is considered one of the most important senses for controlling movements. Based on research on motor learning in adults, we know the importance of accurate proprioception information on the control of movements. Difficulties in somatosensory information will impact a developing nervous system’s ability to learn new motor skills. This effect theoretically compounds as the child learns more motor skills with inaccurate somatosensory feedback, laying a poor foundation for further learning. However, our current understanding of how the sensory and motor systems interact in a developing nervous system is limited. The poor understanding of somatosensory in development is in part due to the lack of accurate assessments that measure somatosensory processing in young children. Current somatosensory assessments are limited to clinical observations and parent reports on the child’s behavior, which lack objectivity and do not provide a standard for comparison. Without objective assessments of somatosensory processing in young children, somatosensory processing deficits are often not identified until later in their childhood, when they present with motor delays. We developed and pilot tested innovative methods to measure somatosensory processing in children as young as 1 year old. The overall objectives of this project is to study somatosensory development in young children, develop a method to identify children who have challenges with somatosensory processing, and to examine the predictive relationship between somatosensory processing challenges in early childhood with later motor development. We hypothesize that somatosensory develop play a major role in predicting motor skill development and participation in activities of daily living in children who were born preterm. This study is part of a larger research program that aims to better our understanding of somatosensory development in children. We strive for early identification of children with somatosensory deficits, and to develop targeted interventions for these deficits in children.

项目摘要 早产儿是发展感觉运动缺陷的高危人群。虽然大多数 早产儿没有神经肌肉的诊断，如脑瘫，许多有轻度至 中度运动延迟。这些运动延迟属于发育协调障碍的诊断范围， 发育性运动障碍是一种运动规划和协调困难的疾病，从理论上讲， 与躯体感觉缺陷有关我们推测躯体感觉处理的缺陷可能先于此 早产儿的诊断，但由于缺乏可靠和有效的评估， 用于幼儿的方法。 躯体感觉是指来自身体的感觉信息，包括触觉和本体感觉。 本体感觉--让我们知道我们的身体是如何运动的，以及在哪里运动的感觉--被认为是 最重要的控制动作的感官。根据对成人运动学习的研究，我们知道， 准确的本体感觉信息对运动控制的重要性。躯体感觉障碍 信息将影响发育中的神经系统学习新运动技能的能力。这种效应理论上 化合物，因为孩子学习更多的运动技能与不准确的体感反馈，奠定了一个穷人 进一步学习的基础。然而，我们目前对感觉和运动系统如何 在发育中的神经系统中相互作用是有限的。 对发育中的体感的理解不足，部分原因是缺乏准确的评估 来测量幼儿的躯体感觉处理。目前的体感评估仅限于 临床观察和家长对孩子行为的报告，缺乏客观性，不能提供一个 标准进行比较。如果没有对幼儿躯体感觉处理的客观评估， 躯体感觉处理缺陷通常直到他们的童年后期才被发现， 运动延迟 我们开发和试点测试创新的方法来衡量儿童的体感处理年轻 一岁的时候。该项目的总体目标是研究幼儿的体感发育， 开发一种方法来识别有躯体感觉处理挑战的儿童，并检查 儿童早期躯体感觉加工障碍与后期运动障碍的预测关系 发展我们假设躯体感觉发育在预测运动技能中起主要作用 早产儿的发育和参与日常生活活动。 这项研究是一个更大的研究计划的一部分，该计划旨在更好地了解体感 儿童的发展。我们致力于早期识别儿童的躯体感觉缺陷，并 针对儿童的这些缺陷制定有针对性的干预措施。
