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. !

项目概要脑瘫（CP）是最常见的小儿神经系统疾病。 CP是由损坏引起的发育过程中的大脑区域。 CP 会导致虚弱、语气改变和协调异常。单方面痉挛性 CP (USCP)，损害以单侧为主。尽管 CP 被定义为运动障碍，大约 80% 的 USCP 患者存在感觉缺陷，从而限制了康复程度。那里对 USCP 儿童的感觉和运动系统如何相互作用知之甚少。减值 USCP 儿童的运动和感觉功能主要是单独（而不是一起）研究的，尽管随意运动需要感觉和运动处理的整合。此外，虽然虽然运动系统的特性已经得到了更好的描述，但对于其位置、类型和运动方式的了解仍然有限。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触觉和肢体位置感觉的精细程度导致 USCP 儿童的运动缺陷。为了实现我们的目标，我们不仅要了解感官系统会影响运动障碍，但我们必须确定儿童的病变和大脑连接如何造成这些损害。我们的中心假设是感觉功能障碍在 USCP 儿童进行功能性、熟练动作的能力。我们还假设损坏特定的大脑区域会导致特定类型的损伤。拟议工作的理由是证明感觉障碍和运动缺陷之间的密切关系将引导开发让儿童在有意义的复杂过程中使用感觉信息的疗法任务，以增强运动功能为目标。！
