Multimodal Pediatric Motor Recovery System

描述(由申请人提供)：目标是设计、建造和临床评估多模式儿科运动恢复系统，即儿科辅助系统。开发的重点将是脑瘫(CP)患者上肢的功能运动恢复。儿科辅助器应该改善CP运动缺陷的功能恢复的时间进程和数量。该系统将利用可穿戴式刺激和传感技术自适应地控制视频游戏界面，并提供一个基于家庭的系统，用于继续和监测治疗。用户佩戴的游戏袖子将嵌入干表面肌电(EMG)记录电极、运动传感器、刺激器单元和小型无线电收发机。动作、协调模式和/或肌电水平将转化为临床医生定义的视频游戏命令。对瘫痪肌肉的指令阈值和功能性电刺激(FES)将根据用户的视频游戏表现进行自适应调整。与功能改善相关的量化措施也将被记录并提交给临床医生。在第一阶段，我们假设：1)可穿戴遥测系统将准确记录肌电和运动数据并控制游戏输入；2)可以实现调整视频游戏参数和FES的自适应算法；3)系统将通过视频游戏界面提供有效的反馈。

DESCRIPTION (provided by applicant): The objective is to design, build, and clinically assess a Multimodal Pediatric Motor Recovery System, the PediAssist. Development will focus on functional motor recovery in the upper extremity of cerebral palsy (CP) patients. The PediAssist should improve the time course and amount of functional recovery from CP motor deficits. The system will utilize wearable stimulating and sensing technology to adaptively control a video game interface and provide a home-based system for continuing and monitoring therapy. A user worn game sleeve will be embedded with dry surface electromyography (EMG) recording electrodes, kinetic sensors, a stimulator unit, and a small radio transceiver. Movements, coordination patterns, and/or EMG levels will translate to clinician defined video game commands. Command thresholds and functional electrical stimulation (FES) to paralyzed muscles will be adaptively modulated based on user video game performance. Quantitative measures related to functional improvement will also be recorded and presented to clinicians. During Phase I, we hypothesize that 1) the wearable telemetry system will accurately record EMG and kinetic data and control game inputs 2) adaptive algorithms for modulating video game parameters and FES can be implemented, and 3) the system will provide effective feedback through the video game interface.
