Peripheral-central Correlation Study on the Treatment of Chronic Tinnitus With Dao qi Tong Luo Based on the Theory of Connecting the Two Ears to the Brain
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.
