Spinal cord injury (SCI) is a condition with a low incidence but high disability rate, based on the central nervous system's ability to reorganize itself during the acquisition, retention, and consolidation of motor skills. Therefore, the focus of post-SCI interventions is primarily on the recovery of motor function (including walking ability and limb function), functional neurological rehabilitation, and the improvement of quality of life. Both brain-computer interfaces (BCI) and electrical stimulation technologies have shown promising research progress when used individually after SCI. This article discusses the integration of these advanced technologies, where implantable BCIs provide neural recording capabilities with increased spatial resolution and have combined complex neural decoding algorithms with increasingly powerful electrical stimulation techniques to advance efforts toward better improving the prognosis of SCI patients, while also providing certain references and theoretical support for subsequent research。
