Pregnant women in the VR group were given adaptive three-dimensional (3D) glasses that fit snugly on their heads to optimize image quality and provide full distance adjustment. All pregnant women in the group were allowed to wear the glasses for a few minutes before the application in order to get used to the glasses. The image to be projected on the glasses was provided by placing a smartphone compatible with the glasses on the front of the glasses. Pregnant women in the VR group were shown an image of a green landscape with a relaxing sound accompanying the 3D images. Pregnant women in the VR group were shown an image of green nature due to the proven psychologically relaxing effect of green. Since the content in question is prepared in 360 degrees, the person wearing the glasses finds herself in the virtual world and experiences the feeling of being there, no matter which direction she looks.

The music was provided to the pregnant women with wireless headphones worn over the head, an electronic acoustic device with sound-enhancing ear pads, and an adjustable headband. These headphones allowed the pregnant women to listen to music in isolation. The music played in the study was determined with the recommendation of the Research and Promotion of Turkish Music (TUMATA), which operates in Turkey and carries out treatment studies with Turkish music. Accordingly, pregnant women were made to listen to Acemashiran maqam, which is thought to have a positive effect on the uterus, the baby in the womb, and facilitate birth. According to TUMATA, Acemashiran Maqam has a fiery nature. It is a dry-hot makam. It is effective on bones and the brain. It helps balance fat in the body.

The State Anxiety Inventory (SAI) and Trait Anxiety Inventory (TAI) were used to measure the anxiety levels of pregnant women. The scale was developed by Spielberger and colleagues, and its Turkish validity and reliability were examined by. The scale consists of 40 items, 20 in the SAI scale and 20 in the TAI scale. With the state anxiety scale, it is possible to determine how the individual feels at that moment and under those conditions, and with the trait anxiety scale, it is possible to determine how the individual feels in general. The scale is a 4-point Likert type. The scale includes items consisting of direct and inverted statements. When calculating the total score, the total weighted score of the direct statements is subtracted from the total weighted score of the inverted statements. To the result obtained, 50 is added for the state anxiety scale and 35 for the trait anxiety scale. The final score obtained shows the anxiety level of the individual.

It is a form in which heart rate (diastolic blood pressure (DBP) and systolic blood pressure (SBP)) is assessed by a calibrated sphygmomanometer, is recorded before and after the NST procedure.

It is a form in which pulse rate (maternal heart rate (MHR)), estimated by pulse oximetry, is recorded before and after the NST procedure.
