Significant variables extraction of post-stroke EEG signal using wavelet and SOM kohonen

Abstract: Stroke patients require a long recovery. One success of the treatment given is the evaluation and monitoring during recovery. One device for monitoring the development of post-stroke patients is Electroencephalogram (EEG). This research proposed a method for extracting variables of EEG signals for post-stroke patient analysis using Wavelet and Self-Organizing Map Kohonen clustering. EEG signal was extracted by Wavelet to obtain Alpha, beta, theta, gamma, and Mu waves. These waves, the amplitude and asymmetric … Show more

“…EEG signal data recording uses Emotiv wireless EEG which was taken from previous research on 50 people, 25 post-stroke patients and 25 no strokes using 128 Hz sampling frequency from 14 channels namely AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T8, FC6, F4, F8, and AF4 [6]. Electrode placement on EEG is carried out by the International Federation of Societies of Electroencephalography standards using the Modified Combinatorial Nomenclature (MCN) system.…”

“…However, the EEG signal is non-stationary, has a small amplitude, so it is not easy in visual observation. The EEG signal consists of wave components based on frequencies, namely Alpha waves (8)(9)(10)(11)(12)(13), Theta waves (4-7 Hz), and Delta waves (0.5-3 Hz) [6]. Therefore, extracting the EEG signal into a frequency component becomes useful [7].…”

“…This result is higher than previous studies using the features of Alpha -Beta -Mu -Amplitude -Asymmetric of Alpha -Asymmetric of Beta -Asymmetric of Amplitude that gave 74%. In meanwhile, using all features obtained an accuracy of 70% [4]. However, other study involved emotional variables of post-stroke patients, which used Wavelet, KNN, and Probabilistic Neural Networks provided 82% of accuracy [7]].…”

“…Neurologist usually observes the rhythm or density of waves, amplitude, changes in amplitude, differences in amplitude between symmetric channels, and the presence of low-frequency waves such as Delta, Theta, and Mu [4]. Previous research used motor imagery parameters to identify the motor skills of paralyzed limbs [5].…”
