反馈技术在运动功能康复治疗中的应用

Application of Feedback Techniques in Motor Function Rehabilitation

反馈是执行运动功能过程中的非常重要的信息交换模式,它以体感信息、触觉信息、视觉信息、听觉信息等方式将运动过程的信息传送到中枢神经,调控运动功能执行的时间和空间精度。本文从反馈的作用原理、技术方法和治疗效果等方面,分析和综述了肌电信号反馈、机器人辅助运动康复训练、高级认知过程反馈及三维虚拟技术等几种反馈技术对运动功能康复治疗的作用。

Feedback is an important way of information transmission in motor function output. Movement-related information can be transmitted as proprioceptive, hapticl visual and/or audial information to the central nervous system for control and modification of the temporal and spatial precision of motor output. Here presented is a systematic discussion on the principle, technique and effect for some typical motor function rehabilitation methods such as treatment based on EMG feedback, robot-aided movement therapy, high-levd perceptional feedback and motor training effect with 3-D virtual reality environment.
