The Effect of Virtual Reality and Music in High-Risk Pregnants on Non-Stress Test

Aim: The aim of this study is to determine the effects of virtual reality and listening to music during the NST procedure on NST parameters, anxiety and satisfaction in high-risk pregnant.

Hypotheses H01 In the NST process, there is no difference between the NST parameters of the virtual reality group and the NST parameters of the control group.

H02 In the NST procedure, there was no difference between the anxiety score of the virtual reality group and the anxiety score of the control group.

H03 There is no difference between the satisfaction score of the group in which virtual reality was applied in the NST procedure and the satisfaction score of the control group.

H04 In the NST process, there is no difference between the NST parameters of the group to which the virtual reality is applied and the NST parameters of the musical group.

H05 In the NST procedure, there was no difference between the anxiety score of the group in which virtual reality was applied and the anxiety score of the music group.

H06 In the NST process, there is no difference between the satisfaction score of the group to which the virtual reality was applied and the satisfaction score of the music group.

H07 In NST operation, there is no difference between the NST parameters of the music group and the NST parameters of the control group.

H08 In the NST procedure, there was no difference between the anxiety score of the music group and the anxiety score of the control group.

H09 There is no difference between the satisfaction score of the music group and the satisfaction score of the control group in the NST procedure.

The study will be carried out in three different groups. The practice will start with meeting the high-risk pregnant who apply to the NST. After the women are evaluated in terms of eligibility criteria for the research, the high-risk pregnant who are eligible will be informed about the research and written informed consent will be obtained from the high-risk pregnant who accept. The random distribution of high-risk pregnant to the study groups will be carried out using the Block Randomization method. The following applications will be made to the groups.

Virtual Reality Group In addition to the routine procedure, virtual reality glasses will be applied to the high-risk pregnant in the virtual reality group of the research. Virtual reality glasses is a device that works on compatible smart mobile phones. After the NST device is connected and, the high-risk pregnant included in the experimental group will be made to watch a video lasting an average of 40 minutes with virtual reality glasses until the procedure is completed.

Music Group In addition to the routine procedure, the high-risk pregnant women in the music group of the research will listen to the relaxing music used in the virtual reality application with headphones.

Control Group The high-risk pregnants in the control group of the study will not be subjected to any treatment other than the routine procedure.
