Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the effectiveness of vagus nerve stimulation in patients with right and left hemiparesis will be compared with each other and with the sham application.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This prospective study will include 80 participants with a diagnosis of ischemic stroke who meet the inclusion criteria. In addition to the conventional rehabilitation program, non-invasive vagus nerve stimulation will be applied to the participants through the left ear with the Vagustim™-Ear tens electrode. As a vagus stimulation protocol, 10 sessions, 30 minutes, noninvasive auricular stimulation will be applied, stimulation frequency is 10 Hz, the pulse width is 300 µs, biphasic. In the study, sham vagus nerve stimulation (0 mA) will be applied to the participants in the control group. The study will be completed when the evaluation of the participants is made in the 1st and 3rd months after the last intervention. The upper extremity functions of the patients participating in the study were determined by Fugl-Meyer upper extremity test and box and block test, upper and lower extremity spasticities by modified Ashworth scale, and sleep quality by Pittsburgh sleep quality index. Quality of life will be evaluated with the stroke-specific quality of life scale, balance functions with the Berg balance test, dependency levels in daily activities with the Barthel index, and sympathetic dysfunctions with COMPASS-31. Participants' blood pressure and pulse values will be evaluated before and after each session.
