小波分析用于磁场刺激诱发肌电信号的实时检测

Wavelet Analysis for Real-time Detection of Electromyography(EMG) under Magnetic Stimulation

肌电信号是在皮肤表面记录下来的神经和肌肉的系统活动时的生物电信号 ,有很好的临床价值。文章着重介绍应用小波分析中的奇异点探测理论 ,对磁场刺激下的诱发肌电信号进行分析 ,实时地提取磁场刺激的诱发肌电信号特征。验证了小波分析理论在分析非平稳的随机信号的优越性 ,是信号分析的又一有力工具。

EMG signal is an one-dimensional time series signal of neuromuscular system,which is very helpful for doctors to analysis the illness of patients.The analysis study of EMG signals under magnetic stimulation with the singular point theory of wavelet transformation is introduced which can determine the location of magnetic stimulation signal.This proves that wavelet transform do much better in the analyzing signal aspects.
