About

By comparing the clinical manifestations, ABR parameters and cerebral cortex blood oxygen levels of chronic tinnitus patients and healthy subjects under two different body states, the peripheral-central correlation of chronic tinnitus patients was explored, and the modern scientific significance of the theory of "two ears connecting the brain" was initially expounded. On this basis, the immediate and cumulative effects and peripheral-central correlation of "dao qi tong luo" intervention in chronic tinnitus were observed, and the effective mechanism of "dao qi tong luo" treatment was explored.

Full description

The study will enroll 15 healthy subjects and 72 subjects with chronic tinnitus. Functional near infrared spectroscopy (fNIRS) will be used to examine specific brain regions, and ABR techniques will record auditory brainstem responses in chronic tinnitus patients and healthy subjects. Lateral comparison was made between chronic tinnitus patients and healthy subjects on the parameters of auditory brainstem response and the level of oxygen outside the cerebral cortex, and the data of the two were integrated to conduct correlation analysis and correlation analysis with clinical manifestations, so as to compare the correlation between peripheral and central auditory function in different body states. Subsequently, the chronic tinnitus subjects will undergo a course of acupuncture treatment. At the end of acupuncture and moxibustion treatment, the immediate and cumulative effects and peripheral - central correlation of "dao qi tong luo" intervention in chronic tinnitus were observed, and the effective mechanism of "dao qi tong luo" treatment was explored.
