Application of brain-computer interface based on hybrid modalities:a new direction in neural rehabilitation
As the aging population and the number of patients with chronic diseases increase,the field of rehabilitation medicine faces both significant challenges and opportunities.Non-invasive brain computer interface(BCI)technology,as an innovative diagnostic and therapeutic tool,brings new hope to patients with motor disabilities caused by central nervous system damage such as stroke.Compared to traditional rehabilitation training,single-modal BCI technology has the advantage of activating sensory-motor cortex and assisting patients'rehabilitation from a brain-level perspective,but each single-modal paradigm has its limitations.Hybrid modalities have been a recent research focus,aiming to improve the overall system's reliability and accuracy by combining two modalities.Based on this,a novel motor-visual hybrid modality BCI technology is proposed,with an average classification accuracy of 86.67％in online experiments.It can simultaneously evoke responses from the motor cortex and visual cortex,and is expected to become a new paradigm for active rehabilitation and neural reshaping.
