The persistentvegetativestatePVS was first proposed by Jennett and Plum in 1972 to refer to a state in which a person still lacks conscious activity and loses language after a period of severe brain injury, while retaining only unconscious postural adjustment and motor functions. The basic principle of deep brain electrical stimulation (DBS) for the treatment of vegetative state is that the arousal system, which maintains the body’s consciousness after brain injury, is damaged. increase the physiological electrical activity of the human brain, thus bringing it to a level that maintains consciousness. In 2007, the journal Nature reported that after the implantation of a brain pacemaker in the brain of a patient with severe brain damage who had been in a coma for 6 years, the patient could speak, comb his hair, brush his teeth, play cards with his family, and perform simple body movements, which provided an important reference for the treatment of this type of patients. This provides an important reference for the treatment of this type of patient.
