Investigation of the Efficacy of Non-Invasive Vagus Nerve Stimulation and Physiotherapy in Unilateral Vestibular Hypofunction Patients

It was planned to include 40 patients diagnosed with UHV in the study. Patients were randomized into 2 separate groups (20 people in the vestibular rehabilitation group, 20 people in the vagus nerve stimulation group in addition to vestibular rehabilitation).

• non-invasive vagus nerve stimulation (Device): non-invasive vagus nerve stimulation: patients will receive non-invasive vagus nerve stimulation.
• vestibular rehabilitation (Behavioral): vestibular rehabilitation: Patients will be given specially structured vestibular rehabilitation exercises.

Primary outcomes

• Modified-CTSIB [30 minutes]: Modified-CTSIB; It is generally used as a semi-quantitative test measurement and clinical practice in which points are scored based on the ability to perform various standing static positions It is a test. It covers different situations where the patient must stand under different conditions: foam surface versus hard floor, tested with eyes open and closed in six different test groups.
• Semitandem test [10 minutes]: semitandem stance positions; The conditions (sec) of remaining in balance with eyes open and closed on hard and soft surfaces will be measured.
• tandem test [10 minutes]: tandem semitandem stance positions; The conditions (sec) of remaining in balance with eyes open and closed on hard and soft surfaces will be measured.
• one-leg standing test [10 minutes]: one-leg standing test; The conditions (sec) of remaining in balance with eyes open and closed on hard and soft surfaces will be measured.
• Unterberger test [5 minutes]: Unterberger test: The patient first takes 10 steps quickly with his eyes open, then With his eyes closed, he takes 50 steps quickly in place. If there is a lesion, apply it to the side of the lesion. correct deviation occurs.
• VAS Visual Analogue Scale (dizziness severity) [5 minutes]: Visual Analogue Scale will be applied to evaluate dizziness severity and patient satisfaction. With this scale, scoring from 0 to 10 is requested. While 0 indicates the lowest dizziness severity and lowest patient satisfaction, 10 indicates the highest dizziness severity and highest patient satisfaction.
• Dynamic visual acuity test [5 minutes]: Dynamic visual acuity test; It measures the ability to see an object during rapid head movements.

Secondary outcomes

• Dizziness Handicap Inventory Scale [5 minutes]: It was developed to measure disability in patients complaining of dizziness and imbalance and is used in treatment follow-up. It is a survey consisting of 25 questions about the patient's physical (7 questions), functional (9 questions) and emotional (9 questions) status, and which patients can apply themselves in line with their complaints. Patients rate the questions as 0 (no), 2 (sometimes) and 4 (yes) based on their complaints. high scores describe severe dizziness.
• Tampa Kinesiophobia Scale [5 minutes]: The Tampa Kinesiophobia Scale will be used to evaluate kinesiophobia. It is a 17-question scale developed to measure fear of injury. The scale includes injury/re-injury and fear-avoidance parameters in work-related activities. High scores describe severe kinesiophobia.
• Hospital Anxiety and Depression Scale (HAD) [5 minutes]: The Tampa Kinesiophobia Scale will be used to evaluate kinesiophobia. It is a 17-question scale developed to measure fear of injury. The scale includes injury/re-injury and fear-avoidance parameters in work-related activities. High scores describe higher levels of depression and anxiety.
