TRAJECTORY MODIFICATION IN CHRONIC STROKE PATIENTS

这个项目的长期目标是产生一个反馈培训 系统，以提高慢性中风患者的运动恢复， 上肢运动轨迹的修正第一阶段的具体目标 （1）定制现有的测试站，以执行以下操作： 右侧偏瘫中风人群的伸展运动;（2）行为 研究确定该类型河段的正常航迹;（3） 设计用于提供基于听觉反馈的仪器和软件 运动学信号特征;（4）制定反馈策略， 使受损的轨迹朝着既定的规范;（5）行为 一项针对中风患者的研究，以确定该系统是否可以诱导 改善受损的轨迹，如果反馈对于这种改善至关重要， 改进，如果有适应和学习的轨迹 改性 拟议工作的技术创新在于 在生理学研究中使用最新的运动学技术， 在任务要求中考虑不同的协同模式， 强调功能上有意义的培训任务， 使用调节的感觉反馈来实现改进。 商业 由此产生的系统的应用是作为一种康复工具， 常规治疗。

The long term objective of this project is to produce a feedback training system to enhance the motor recovery of chronic stroke patients by means of upper extremity trajectory modification. The specific aims of Phase I are to: (1) customize an existing test station for the execution of reaching movements by the right hemiparetic stroke population; (2) conduct a study to determine the normal trajectories for this type reach; (3) design instrumentation and software for delivering auditory feedback based on kinematic signal characteristics; (4) develop a feedback strategy for bringing the impaired trajectory toward the established norm; (5) conduct a study of stroke patients to determine if the system can induce improvement of impaired trajectories, if feedback is essential for such improvement, and if there is adaptation and learning in trajectory modification. The technological innovation of the proposed work lies in the use of recent kinematic technology in physiological investigations, the consideration of different synergy patterns in the task requirements, the emphasis on training tasks that are functionally meaningful, and the use of regulated sensory feedback to effect improvement. The commercial application of the resulting system is as a rehabilitation tool to augment conventional therapy.
