Recent advancements in brain-computer interface (BCI) technology have provided novel opportunities for individuals with paralysis due to SCI. Consequently, research on the application of BCI for treating SCI has received increasing attention from scholars worldwide.

To facilitate visualization and quantitative analysis of the published literature, we used VOSviewer and CiteSpace software tools.
