Effect of Transcutaneous Auricular Vagus Nerve Stimulation Application on Respiratory Functions in Stroke Patients
Sponsor: Fenerbahce University
Summary
The purpose of this study is to evaluate the effectiveness of Transcutaneous Auricular Vagus Nerve Stimulation (TAVSS) in improving respiratory muscle strength and function in chronic stroke patients. It aims to explore TAVSS as a potential complementary approach in enhancing rehabilitation outcomes for this population.

Transcutaneous Auricular Vagus Nerve Stimulation
TAVSS is an application system that uses an electrical transcutaneous stimulation device placed on the concha or tragus of the ear. Functional Magnetic Resonance Imaging studies have shown that stimulation of these areas activates the ipsilateral nucleus tractus solitarius (NTS) via vagal projections to the brainstem and forebrain. Unlike cervical vagus nerve stimulation, TAVSS utilizes a physiological pathway to activate the NTS and the dorsal motor nucleus, which subsequently sends impulses bilaterally to the heart surface via efferent cervical vagus nerves. Therefore, this technique eliminates the possibility of directly and asymmetrically stimulating cardiac motor efferent fibers, which could lead to adverse cardiac events. TAVSS combines advantageous qualities such as being non-invasive, cost-effective, convenient, and efficient.
