发布时间：2019-05-08 20:58
【摘要】：注意缺陷障碍（attention deficit disorder, ADD）是儿童和青少年时期常见的一种行为问题之一。目前对ADD患者的治疗，主要可以分为药物治疗和非药物治疗，非药物治疗方法中的行为治疗因其疗效明显且无副作用而逐渐受到重视。脑电反馈作为生物反馈疗法的一种，在注意力缺陷治疗方面具有独特的优势。本文提出了一种基于脑电反馈的注意缺陷障碍矫治系统设计方法。 本文首先介绍了脑电波的相关知识，包括脑电波的简介，脑电波的采集和影响脑电波的因素，进而引出了脑电生物反馈技术的基本原理和发展现状，然后是结合脑电生物反馈技术构造整个反馈矫治系统。整体的脑电反馈矫治系统包括硬件和软件两大部分，硬件部分主要实现脑电信号的采集、预处理以及A/D转换传输功能。软件部分一方面是要实现脑电信号的实时还原显示、分析处理功能，另一方面是要根据整个系统的要求，设计实现出对ADD患者起到矫治作用的反馈游戏。本系统的反馈游戏包括赛车游戏和贪吃蛇游戏的实现，设计游戏的关键是要结合能够表征患者注意力集中度的品质参数。 本系统经过初步的测试表明，可以基本达到预期的设计目的。
[Abstract]:Attention deficit disorder (attention deficit disorder, ADD) is one of the common behavioral problems in children and adolescents. At present, the treatment of ADD patients can be divided into drug therapy and non-drug therapy. Behavior therapy in non-drug therapy has been paid more and more attention because of its obvious curative effect and no side effects. EEG feedback, as a biofeedback therapy, has unique advantages in attention deficit therapy. In this paper, a design method of attention deficit disorder correction system based on EEG feedback is proposed. In this paper, we first introduce the relevant knowledge of EEG, including the introduction of EEG, the collection of EEG and the factors that influence EEG, and then introduce the basic principle and development status of EEG biofeedback technology. Then the whole feedback correction system is constructed by combining EEG biofeedback technology. The whole EEG feedback correction system consists of two parts: hardware and software. The hardware mainly realizes the functions of EEG signal acquisition, preprocessing and A / D conversion and transmission. On the one hand, the software part is to realize the real-time display of EEG signal, analysis and processing functions, on the other hand, according to the requirements of the whole system, we should design and implement a feedback game which plays a corrective role in ADD patients. The feedback game of the system includes the realization of racing game and Snake game. The key to designing the game is to combine the quality parameters that can characterize the concentration of patient's attention. The preliminary test of the system shows that the expected design purpose can be basically achieved.
