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 出生早产儿的儿童患有感觉运动缺陷的风险很高。虽然大部分 出生早产的孩子没有神经肌肉诊断，例如脑瘫 中度电动机延迟。这些电动机延迟属于发育协调障碍的诊断或 发育障碍，在运动计划和协调方面困难的状况，从理论上讲是 与体感不足有关。我们假设体感处理的不足可能在此之前 早产儿的诊断，但由于缺乏可靠且有效的评估，这些定义未被确定 与幼儿一起使用的方法。 躯体感觉是指身体的感觉信息，包括触摸和本体感受。 本体感受 - 让我们知道身体如何和何处移动的感觉 - 被认为是 控制运动的最重要感觉。根据成人运动学习的研究，我们知道 准确的本体感受信息的重要性。体感的困难 信息将影响发展中神经系统学习新运动技能的能力。从理论上讲，这种效果 当孩子通过不准确的体感反馈学习更多的运动技能时，化合物的化合物却差不多 进一步学习的基础。但是，我们目前对感官和运动系统如何的理解 在发育中的神经系统中相互作用是有限的。 对发展中体感的不良理解部分是由于缺乏准确的评估 这种衡量幼儿的体感处理。当前的体感评估仅限于 临床观察和父母报告了孩子的行为，这些行为缺乏客观性，并且不提供 比较标准。没有对幼儿体感处理的客观评估， 通常直到童年后期才发现体感的处理缺陷，当 电机延迟。 我们开发并进行了试点测试的创新方法，以测量年轻儿童的体感处理 1岁。该项目的总体目标是研究幼儿的体感发展， 开发一种方法来识别在体感处理方面面临挑战的孩子，并检查 较早的运动的早期运动挑战之间的预测关系与较晚的电动机 发展。我们假设体感发展在预测运动技能方面起着重要作用 开发和参与天生早产儿童日常生活的活动。 这项研究是一项更大的研究计划的一部分，旨在更好地理解体感 儿童的发展。我们努力早日确定具有体感缺乏症的儿童，并 为这些儿童缺陷而制定了针对性的干预措施。
