NCT04706871

Brief Summary

Objective: To observe the effect of the treatment of transcutaneous auricular vagus nerve stimulation (taVNS) for the functional dyspepsia (FD). Methods: We accrued 94 patients at Beijing TongRen Hospital. All treatments were self-administered by the patients at home after training at the hospital. Patients completed questionnaires at baseline and after 4 weeks, 8 weeks, 12 weeks. The FD Symptoms Index, Functional Dyspepsia Quality of Life Scale (FDDQL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and Self-Depression Rating Scale (SDS) were performed to evaluate the therapeutic effects. A difference of P \< 0.05 was considered statistically significant.

Interventions

taVNSDEVICE

taVNS was applied using a Huatuo stimulator (SDZ-IIB) developed by Suzhou manufacture of Medical Device and Material. Stimulation parameters was 1 mA of electrical current at a frequency of 30 Hz with pulse duration ≤ 1 ms, for 30min, administered twice daily. The two electrodes were placed on the cymba conchae and concha around the left ear.
