摘　　要：提出了基于脑电生物反馈技术对失眠障碍患者进行康复训练的非药物康复治疗方法。设计出利用脑电模拟前端芯片ADS1299的脑电信号(EEG)采集装置,采用了QT和MATLAB混合编译完成脑电信号的预处理及利用小波变换分解出的α波特征信号表征大脑状态,通过音视频将当前脑状态信号反馈给患者,根据量化指标对应的康复方案,指导失眠障碍患者训练平静放松的状态,达到治疗失眠康复目的。并采用匹兹堡睡眠质量量表验证了失眠康复仪对失眠障碍患者显示出良好改善效果。经测试该方法对患者无副作用且有效。A rehabilitation treatment without drug based on EEG biofeedback technology was proposed to rehabilitate insomnia patients.The EEG acquisition device is designed based on ADS1299,using QT and MATLAB to compile the EEG signal.Theαwave characteristic signal decomposed by wavelet transform is used to represent the brain state,which is fed back to the patients through audio and video.According to the quantitative indicators corresponding to the rehabilitation scheme,make insomnia patients obtain a calm and relaxed state to achieve the purpose of insomnia treatment and rehabilitation.Pittsburgh sleep quality index was used to verify the effect of insomnia rehabilitation instrument on insomnia patients.The test shows this device has no side effects and is effective for insomnia patients.
