 Spinal cord injuries are a major cause of disability worldwide, with a high mortality rate and a significant impact on quality of life. Researchers have made great strides in understanding the underlying causes of spinal cord injury and developing treatments to promote neural regeneration and circuit reconstruction. These advances include the use of bioactive materials, stem cells, and novel technologies such as electrical stimulation, magnetic fields, and ultrasonography. While these techniques have shown promise in preclinical studies, they still need to be tested in clinical trials before being used in patients.
