Effect of Transcutaneous Auricular Vagal Nerve Stimulation on Functional Dyspepsia

NCT04668534 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 300

Last updated 2020-12-16

No results posted yet for this study

Summary

Patients with dyspeptic symptoms vary from 10% to 20% globally. Up to 70% of patients with dyspepsia who undergo endoscopy have unremarkable examination and are diagnosed with functional dyspepsia (FD). Given the lack of information related to its pathophysiology, the treatment is largely empirical and of limited efficacy. Previous small study showed therapeutic potential of transcutaneous auricular vagal nerve stimulation (taVNS) for FD. This study aims to investigate whether taVNS can improve the dyspeptic symptoms of patients with FD.

Conditions

  • Functional Dyspepsia

Interventions

DEVICE

taVNS 10

Patients were given taVNS (by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 10 Hz; current intensity: minimal pain threshold; pulse width: 500 μs)

DEVICE

taVNS 25

Patients were given taVNS (by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 25 Hz; current intensity: minimal pain threshold; pulse width: 500 μs)

DEVICE

Control

Patients were given taVNS (by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 10 Hz; current intensity: minimal pain threshold; pulse width: 500 μs)
