Rehabilitation Based on BCI: An Innovative Enhancement for Sensorimotor Cortex Rhythms Systemization

Abstract

The research proposes a novel strategy for categorizing electroencephalograms (EEG) in real‐time brain‐computer interfaces that have rehabilitation applications. The methodology utilizes Five Cross‐Common Spatial Patterns (FCCSP) to develop a motor movement/imagery systemization model that extracts multi‐domain characteristics with excellent performance. The goal is to eliminate the impact caused by EEG's nonstationarity. The article highlights the findings of a real‐time technique that is incorporated into a comprehensive prediction system, and it offers an innovative method to boost accuracy in real‐time Sensory‐Motor cortex Rhythms (SMR). The accuracy increased from 57.14% using raw EEG to 85.71% after preprocessing, and from 58.08% to 97.94% in public domain SMR. The proposed Butterworth bandpass filter is optimized using the FCCSP to determine the ideal bandwidth that incorporates the whole EEG features in beta waves. The Hybrid Systemization of the Correlated Feature Removal classifier is then integrated with the FCCSP method to create improved predictive models. As a consequence, while applied to real‐time and PhysioNet datasets, the outcome system achieved outstanding accuracy values of 85.71% and 97.94%, respectively. This demonstrates the robustness of the strategy to increase SMR prediction efficiency.
