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)：我们假设强化肌肉可能是改善脑瘫儿童步态和功能的一种替代方案。我们的长期目标是开发一种比目前的方法更好的强化疗法。我们提出的治疗方法是基于使用一个集成了类似游戏的虚拟现实(VR)模拟的原型罗格斯脚踝机器人。具体目标第一个目标是开发罗格斯大学脚踝CP，用于加强CP儿童的脚踝。第二个目标是确定在罗格斯大学的踝关节CP上进行为期12周的强化踝背/足屈肌力量训练计划是否会改善患有CP的儿童的踝关节力量、步态、功能和生活质量。方法1)构建Rutgers踝关节CP系统，修改机器人伺服控制，实现主动辅助/被动抵抗踝关节运动；2)扩展基于Rutgers踝关节CP训练的儿童虚拟康复软件。一个新的智能代理软件将把任务消耗要求与患者过去的表现联系起来，以确定机器人的行为(从100%协助到100%抵抗)；3)我们将开发一个网络可访问的数据库模块，用于报告和数据分析。罗格斯大学脚踝CP的数据将在临床现场进行透明的实时采样。随后，数据将通过因特网转发到罗格斯大学现有的数据库服务器。现有的基于网络的临床数据库和图形环境将得到增强，包括传统的CP临床评估方法、来自VR练习的计算机化变量和主观评估问卷；4)6名痉挛双瘫CP患者将参加为期12周的罗格斯踝关节CP上的踝背/踝屈肌力量训练计划。受试者将在干预前、12周干预结束时和另外12周后接受脚踝力量、痉挛、步态分析、GMFM和PEDS QL评估。我们假设受试者在机器人上的训练将在力量、步态、功能和生活质量方面有所改善，并将在至少12周内保持这种增长。NIH相关这个项目将开发一种用于CP中的脚踝力量训练的设备。力量训练可以改善步态和功能。公共健康相关性一种简单的力量训练计划，可以改善步态和功能，通过取消或推迟更昂贵的程序来降低医疗成本。
