项目摘要

PROJECT SUMMARY Cerebral palsy (CP) is the most common pediatric neurological disorder. CP is caused by damage to brain areas during development. CP results in weakness, altered tone and abnormal coordination. In unilateral spastic CP (USCP), the damage has a unilateral predominance. Although CP is defined as a motor disability, approximately 80% of people with USCP have deficits in sensation that limit the extent of rehabilitation. There is a poor understanding of how the sensory and motor systems interact in children with USCP. Impairments in motor and sensory function have largely been studied in isolation (rather than together) in children with USCP, even though voluntary movement requires the integration of sensory and motor processing. Moreover, while the motor system is better-characterized, there is still a limited understanding of how the location, type, and size of a child’s lesion impacts sensorimotor processing. There is an urgent need to identify and quantify sensory factors that impair movement in children with USCP. Our long-term goal is to develop evidence-based ways to improve movement in children with USCP. The overall objective for this project is to determine how fine touch sensation and sensation of limb position contribute to movement deficits in children with USCP. To meet our goal, we must not only know how sensory systems impact impairment in movement, but we must determine how a child’s lesion and brain connectivity contributes to these impairments. Our central hypothesis is that sensory dysfunction plays a key role in the ability of children with USCP to engage in functional, skillful movements. We also hypothesize that damage to specific brain regions cause specific kinds of impairments. The rationale for the proposed work is that demonstration of a strong relationship between sensory impairments and movement deficits will steer the development of therapies that engage children in the use of sensory information during meaningful complex tasks, with the goal of boosting motor function. !

项目摘要脑瘫（CP）是最常见的儿科神经系统疾病。 CP是由损坏造成的发育过程中的大脑区域。 CP导致弱点，音调改变和异常协调。单方面痉挛性CP（USCP），损害具有单方面的优势。尽管CP被定义为运动障碍，但大约80％的USCP患者在感觉上定义了限制康复程度的感觉。那里对感官和运动系统如何在USCP儿童中相互作用是一种不良的理解。障碍运动和感觉功能在很大程度上是在USCP儿童中孤立研究的（而不是一起研究）即使自愿运动需要集成感官和运动处理。而且，电机系统的特征更加特征，对位置，类型和儿童病变的大小会影响感觉运动处理。迫切需要识别和量化损害USCP儿童运动的感觉因素。我们的长期目标是开发基于证据的方法来改善USCP儿童的运动。该项目的总体目标是确定肢体位置的细触摸感和感觉如何在USCP儿童中定义运动的贡献。为了实现我们的目标，我们不仅必须知道感官系统影响影响运动对运动的影响，但我们必须确定孩子的病变和大脑连通性如何有助于这些障碍。我们的中心假设是感觉功能障碍在 USCP儿童从事功能，熟练运动的能力。我们还假设对特定的大脑区域会导致特定种类的损害。拟议工作的理由是感官障碍与动作定义之间存在牢固关系的演示将窃取在有意义的复合物过程中开发使儿童参与使用感官信息的疗法任务，目的是提高运动功能。呢
