Research progress on vagus nerve stimulation for post ⁃ stroke upper limb motor disorders

Vagus nerve stimulation (VNS) is an emerging neuromodulation therapy that has been used in post⁃stroke rehabilitation. In recent years, VNS combined with rehabilitation has been used to improve upper limb motor function in stroke patients, but the mechanisms and optimal stimulation parameters are still unclear. In this paper, we summarize the evidence from basic and clinical studies of VNS combined with rehabilitation for post⁃stroke upper limb motor disorders, and discuss the possible mechanisms and optimal stimulation parameters, provide new ideas for the rehabilitation of post⁃stroke upper limb motor disorders
