项目摘要

DESCRIPTION (provided by applicant): We hypothesize that strengthening muscles may be an alternative for improving gait and function in children with cerebral palsy. Our long-term objective is to develop an improved strengthening therapy compared to today's approaches. Our proposed therapy is based on the use of a prototype Rutgers Ankle robot integrated with game-like virtual reality (VR) simulations. SPECIFIC AIMS The first aim is to develop the Rutgers Ankle CP for use in strengthening the ankles of children with CP. The second aim is to determine if a 12-week intensive ankle dorsi/plantarflexors strength-training program on the Rutgers Ankle CP will improve ankle strength, gait, function, and quality of life of children with CP. METHODS 1) we will construct the Rutgers Ankle CP system and modify the robot servo control to allow active assistance/passive resistance to ankle motion; 2) we will expand virtual rehabilitation software for children with CP training on the Rutgers Ankle CP. A new intelligent agent software will correlate task exertion requirements with patient past performance in order to determine the robot behavior (from 100% assistance to 100% resistance); 3) we will develop a web-accessible database module for reporting and data analysis. Data from the Rutgers Ankle CP will be sampled transparently in real time at the clinical site. Subsequently the data will be forwarded over the Internet to an existing database server at Rutgers University. The existing web-based clinical database and graphing environment will be enhanced to include conventional CP clinical evaluation measures, computerized variables from the VR exercises, and subjective evaluation questionnaires; 4) Six subjects with spastic diplegia CP will participate in a 12-week strength-training program of the ankle dorsi/plantarflexors on the Rutgers Ankle CP. Subjects will be evaluated for ankle strength, spasticity, gait analysis, GMFM, and Peds QL prior to the intervention, at the end of the 12-week intervention, and after an additional 12 weeks. We hypothesize that the subjects will improve in strength, gait, function, and quality of life from training on the robot, and will maintain the gains for at least 12 weeks. NIH RELEVANCE This project will develop a device for ankle strength training in CP. The strength training can be used to improve gait and function. PUBLIC HEALTH RELEVANCE A simple strength training program that improves gait and function will reduce health care costs by eliminating or delaying more expensive procedures.

描述（由申请人提供）：我们假设增强肌肉可能是改善脑瘫儿童步态和功能的替代方法。与当今的方法相比，我们的长期目标是开发改进的增强疗法。我们提出的疗法是基于使用与游戏般的虚拟现实（VR）模拟的原型Rutgers Ankle机器人的使用。具体目的的第一个目的是开发罗格脚踝CP，用于增强CP儿童的脚踝。第二个目的是确定Rutgers Ankle CP上的12周强化脚踝背曲/足底力量训练计划是否会改善CP儿童的脚踝强度，步态，功能和生活质量。方法1）我们将构建Rutgers Ankle CP系统并修改机器人伺服控制，以使主动辅助/对踝运动的被动阻力； 2）我们将在Rutgers Ankle CP上扩展针对CP培训儿童的虚拟康复软件。一个新的智能代理软件将使任务劳动要求与患者过去的表现相关联，以确定机器人行为（从100％援助到100％阻力）； 3）我们将开发一个可用于报告和数据分析的可访问数据库模块。来自Rutgers踝关节CP的数据将在临床部位实时透明地进行采样。随后，数据将通过Internet转发到Rutgers University的现有数据库服务器。现有的基于Web的临床数据库和图形环境将得到增强，包括传统的CP临床评估措施，来自VR练习的计算机变量以及主观评估问卷； 4）六个患有痉挛性diplation CP的受试者将参加Rutgers Ankle CP上的脚踝porsi/Plantarflexors的12周强度训练计划。在干预之前，在12周的干预结束之前以及额外的12周之后，将评估受试者的脚踝强度，痉挛，步态分析，GMFM和PEDS QL。我们假设受试者将在机器人训练中提高强度，步态，功能和生活质量，并将至少维持12周的收益。 NIH相关性该项目将开发一种用于CP脚踝力量训练的设备。力量训练可用于改善步态和功能。公共卫生相关性的一个简单的力量培训计划，可以通过消除或延迟更昂贵的程序来降低步态和功能的简单培训计划。
