The vagus nerve innervates both the uterus and the cervix. It is thought that a successful and positive birth experience can be achieved by stimulating the vagus nerve at the desired level. Making instinctive sounds such as singing, humming, and various exercises are methods that stimulate the vagus nerve. In this project, an application protocol based on polyvagal theory and including breathing, relaxation and voice exercises was prepared. Video-supported application material will be developed in line with the prepared protocol. The video-assisted vagus nerve stimulation intervention is called Vagal Active Tone (VAT). VAT is a new method in the literature and for which we have limited information about labor. This project aimed to determine the effect of vagus nerve stimulation based on Polyvagal theory on labor pain, anxiety, oxytocin, cortisol levels, duration and perception of birth. This study was planned as a randomized controlled experimental study. The number of samples was calculated using the G*power 3.1.9.6 program. After the power analysis, it is aimed to reach a total of 50 people, 25 in the intervention group and 25 in the control group. Data will be collected with Personal Information Form, Labor Monitoring Form, Hormone Levels Monitoring Form, Visual Analogue Scale, State Anxiety Scale, Facial Anxiety Scale and Mother's Birth Perception Scale.
It is aimed to produce new and original evidence-based information with the use of VAT intervention based on polyvagal theory. It is thought that this intervention, which can be easily accessed and applied by pregnant women whenever they want, will contribute positively to labor pain, anxiety, oxytocin and cortisol levels, and the duration and perception of birth.

| Visual Analog Scale (VAS) | Visual Analog Scale (VAS): VAS is a one-dimensional scale that objectively evaluates the pain perception of the pregnant woman. It allows some values that cannot be measured numerically to be converted into numerical form. VAS was developed and used by Bond and Pilowsky in 1966. VAS is a 10 cm ruler scale used to quantitatively determine the intensity of pain, with one end representing painlessness (0 = no pain) and the other end representing the most severe pain (10 = severe pain). The patient marks any place between two points that matches the intensity of the pain. The distance between the end of the scale representing painlessness and the point marked by the patient is measured with a ruler and recorded in cm. This numerical value obtained shows the intensity of the pregnant woman's pain. | 30 minutes later (post intervention) |
| Facial Anxiety Scale (FAS) | Facial Anxiety Scale (FAS): It is a one-dimensional, individual-based anxiety assessment tool. Its Turkish validity and reliability study was conducted on patients receiving mechanical ventilation in intensive care. Using this numerical rating scale, researchers determined the image corresponding to the patient's facial expression by ranking the face using a number from 0 to 10. A higher score indicates a higher level of anxiety . | 30 minutes later (post intervention) |
| State Anxiety Inventory (SAI) | State Anxiety Inventory (SAI): The scale (5) developed by Spielberg and colleagues (1964) to measure the state anxiety levels of normal and abnormal individuals was adapted to Turkish by Öner and Le Compte (1983). The state anxiety inventory was developed to measure a person's anxiety at a certain moment. The 20-item state anxiety inventory is a scale that determines how an individual feels at a certain moment and under a certain condition. SAI is a 4-point Likert-type scale. There are 10 reversed statements on the scale. These statements are items 1, 2, 5, 8, 10, 11, 15, 16, 19 and 20. The state anxiety score is calculated by adding 50 points to the difference between the total weighted scores of direct and reverse statements. The scores obtained in the state anxiety scale theoretically vary between 20 and 80 points. The Cronbach Alpha internal consistency rate of SAI was found to be 0.96. |

In the study, hormone value analyses, statistics and reporting will be blinded. Before the pre-tests are collected in the collection of data, the responsible researcher will contact the statistician who performed the randomization and reach the randomization list. After learning the group information, the responsible researcher will start the application. The participant will be monitored under the supervision of the responsible researcher until they go to the postpartum care unit. A new participant will be included in the study after the participant is sent to the postpartum care clinic. Therefore, the intervention and control groups will be prevented from seeing each other.
For hormone analyses, the hormone tubes will be coded as "A" and "B" groups by the responsible researcher. Hormone value analyses will be performed by an expert laboratory technician who is not aware of the groups independent of the study.

| Maternal Birth Perception Scale (MBS) | Maternal Birth Perception Scale (MBS): It is a tool that assesses how mothers perceive their experiences during normal or unplanned cesarean births. MBS is a 25-item, 5-subscale, and 5-point Likert-type scale developed by Fawcett and Knauth (1997) (7). The sub-dimensions of the scale are experiences during birth (7 items; 3, 5, 6, 8, 15, 17, 18), experiences during the painful period of birth (7 items; 1, 2, 4, 7, 9, 10, 16), postpartum (4 items; 22, 23, 24, 25), spouse participation (4 items; 11,12,20,21), and awareness (3 items; 13,14,19). Since the questions numbered 15-16-17-18-19 of the scale contain negative expressions, the scoring is done in reverse direction in these questions. The translation of ADAÖ into Turkish and the validity and reliability study were carried out by Güngör and Beji (2007). ADAÖ, Cronbach Alpha internal consistency rate was found to be 0.83 (8). Permission for use of the scale was obtained (Appendix-8). | 30 minutes later (post intervention) |
