Research Status of Transcutaneous Auricular Vagus Nerve Stimulation in Treatment of Insomnia
Insomnia is a kind of sleep disorder with difficulty in falling asleep or waking up easily,decreased sleep quality and reduced sleep time as the main clinical manifestations.Its incidence is high,which seriously affects life quality of patients.According to TCM theory,insomnia is mainly caused by the imbalance of Yin and Yang,the decline of Zang-fu function and the disharmony between Ying and Wei.Percutaneous auricular point vagus nerve stimulation is a non-invasive neuro-modulation technique that applies low-frequency pulse electrical stimulation to the auricular skin receptive region.Its mechanism is mainly related to the auricular vagus nerve reflex.Stimulating the local ear region can regulate the body's neurotransmitter and inflammatory response,and can effectively alleviate insomnia symptoms of patients.By searching and sorting out relevant literature,this study summarized the current research status of percutaneous auricular vagus nerve electrical stimulation in treatment of insomnia from the aspects of TCM theory,Western medicine mechanism,stimulation site,parameter application and clinical application.It is aimed to provide ideas for future related studies and help to promote development of non-invasive neuroregulation techniques.
