[Research progress on median nerve electrical stimulation for awakening comatose patients with brain injury].

Abstract

With the development of medicine, the survival rate of patients with traumatic brain injury has gradually increased, and more lives have been successfully saved. However, the number of comatose patients has also risen, leading to prolonged medical care that increases economic burdens on families and society. The awakening of comatose patients is of great significance. As a non-invasive brain stimulation technique, median nerve electrical stimulation (MNS) has been widely used in clinical awakening therapy, and multiple clinical studies have confirmed the effectiveness of this technology. This article summarizes the research progress of this technology from the aspects of coma mechanism, median nerve pathway, awakening mechanism of MNS, clinical application of MNS, parameter setting of electrical stimulation, and neurological function evaluation.
