项目摘要

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.

项目概要尽管大多数早产儿出现感觉运动缺陷的风险很高。早产儿没有神经肌肉诊断，例如脑瘫，许多患有轻度至中度运动迟缓这些运动迟缓属于发育协调障碍或发育性运用障碍，一种运动规划和协调困难的病症，理论上是与体感缺陷有关，我们认为体感处理缺陷可能先于此。早产儿的诊断，但由于缺乏可靠和有效的评估，这些缺陷未被识别适用于幼儿的方法。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如何以及在哪里移动的感觉——被认为是根据对成人运动学习的研究，我们知道控制运动的最重要的感觉。准确的本体感觉信息对体感控制困难的重要性。理论上，信息会影响神经系统学习新运动技能的能力。当孩子通过不准确的体感反馈学习更多的运动技能时，这种情况会变得更加复杂，从而奠定了较差的基础然而，我们目前对感觉和运动系统如何的理解。神经系统发育过程中的相互作用是有限的。对发育过程中的体感了解不足，部分原因是缺乏准确的评估目前的体感评估仅限于测量幼儿的体感处理。临床观察和家长对孩子行为的报告缺乏客观性，不能提供客观的依据没有对幼儿体感处理的客观评估，体感处理缺陷通常直到童年后期才被发现，此时他们表现出电机延迟。我们开发并试点测试了测量儿童体感处理的创新方法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在体感处理方面有困难的儿童，并检查幼儿期体感处理挑战与后期运动之间的预测关系我们率先提出体感发育在预测运动技能方面发挥着重要作用。早产儿日常生活活动的发展和参与。这项研究是一个更大的研究计划的一部分，旨在更好地理解体感我们努力尽早发现有躯体感觉缺陷的儿童，并针对儿童的这些缺陷制定有针对性的干预措施。
