Abstract


Movement neural activity in the brain and muscles strong ties EEG - EMG reflect the functional linkage of the cerebral cortex and muscle movement, to help people understand how the brain controls muscle movement, and the case of some diseases, For example, the diagnosis of Parkinson's disease, cortical myoclonus, the upper limb dystonia and other important value. At present, the correlation coefficient is commonly used to evaluate the correlation of EEG - EMG, the traditional definition of the correlation coefficient EMG confined with EEG band 0-40Hz ignored EMG effective high-frequency information, which requires to find a more appropriate evaluation parameters to examine the relevance of the EEG - EMG. In addition, under the excitation of the different external source load, EEG and EMG rendering each different variation, and the correlation between them will with the Exogenous load excitation change varies, explore the laws of these changes can help people more good understanding and awareness of the brain to control muscle movement mode. External load grip as the excitation source design different excitation conditions the simultaneous acquisition of EEG and EMG experiments, respectively, using the power spectral density, fractal dimension to collaborative analysis of EEG, EMG excitation source with the external load excitation change the law. The study uses wavelet empirical mode decomposition combined to extract EEG and EMG power spectrum of the different bands, and the results show that no significant relationship between EEG power spectral density and exogenous load incentive EMG power spectrum density with significant the exogenous load incentive increases; EEG fractal dimension increased and then decreased with increasing load incentives exogenous EMG fractal dimension with increasing load incentives exogenous approximate line increases. Using a traditional correlation coefficient Evaluation electroencephalogram - electromyogram correlation, and found that with the increase in exogenous load excitation EEG - EMG correlation peak Area by the α and β-band spread to the γ band. The improved evaluation parameters, and EMG highest correlation coefficient EEG concentrated in the band of the β, γ-band EEG gradually increases as exogenous load increase of incentives and EMG. These findings contribute to a deeper understanding of the movement of the human neuromuscular system of different frequency bands of the EEG response different operational states of excitation of different exogenous load of EEG - EMG correlation band changes and size changes and coordination ability, the future rehabilitation of the disabled athletes training has guiding significance.
