Tragus Nerve Stimulation Attenuates Postural Orthostatic Tachycardia Syndrome in Post COVID-19 Infection.

ABSTRACT:

Background

Postural orthostatic tachycardia syndrome (POTS) is characterized by symptoms of orthostatic intolerance and is frequently observed in post-COVID conditions.

Objectives

We conducted controlled, prospective, and randomized clinical trials to explore the potential therapeutic benefits of low-level tragus stimulation (LL-TS) in patients with POTS following COVID-19 infection.

Methods

This study enrolled 57 participants with confirmed post-acute COVID-19 who had been diagnosed with POTS. The ear clip was attached to the right tragus of the patients for stimulation (20 Hz with a 1-ms duration) or sham stimulation. They were divided into two groups: the sham LL-TS group (sham stimulation, n = 26) and the LL-TS group (stimulation for 1 month, n = 31). LL-TS was pe
