Muzyka podczas badania KTG

After the pregnant women were positioned, while the NST procedure was implemented they listened to music for 20-30 minutes. The pregnant women listened to the music on an MP3 player during the application. The duration of the music recorded on the MP3 player was 30 minutes. The music played to the pregnant women was selected by the researchers in accordance with the definition of relaxing music made in the literature. Before the music selection, the researchers communicated with the TÜMATA (Turkish acronym for the "Research and Promotion of Turkish Music Association). After the meeting held with the association, it was decided to use the 'Acemaşiran' (a musical mode in traditional Turkish music). In the study, music prepared by the TÜMATA in the Acemaşiran mode was played. It is stated that Acemaşiran mode helps balance the body, helps the listener relax, facilitates birth, helps correct the wrong position of the fetus in the womb, and has a pain and spasm relieving effect

Pregnant women were not subjected to any intervention during the NST procedure.

Prenatal Comfort Scale (PCS) was used to determine women's comfort level. The short version of the PCS consists of 15 items. Response given to the items are rated on a six-point Likert type scale ranging from 0 to 5 (0 = Strongly disagree, 1 = Disagree, 2 = Undecided, 3 = Somewhat agree, 4 = Agree, 5 = Strongly agree). The minimum and maximum possible scores that can be obtained from the PCS are 0 and 75, respectively. The higher the score is the higher the comfort level is.

The women's systolic blood pressure levels were measured with a calibrated electronic sphygmomanometer. Blood pressure levels are expressed in millimeters of mercury (mmHg).

The women's diastolic blood pressure levels were measured with a calibrated electronic sphygmomanometer. Blood pressure levels are expressed in millimeters of mercury (mmHg).

Heart rate level was determined electronically. Heart rate level was recorded in beats per minute (bpm).

State Anxiety Scale (SAS) was used to determine the anxiety level. The scale is a 4-point Likert type, "not at all" (1), "somewhat" (2), "moderately" (3), "very much" (4). The scale consists of 20 items and items 1, 2, 5, 8, 10, 11, 15, 16, 19 and 20 are reverse scored. To calculate the total score of the SAS, the total score of the reversed items is subtracted from the total score of the non-reversed items. Then, 50 points, which is the constant value of the state anxiety scale, are added to this score. The result is the score for the overall SAS. The total score varies between 20 and 80. The higher the score is the higher the level of the anxiety is. While a score ranging between 0 and 19 indicates "no anxiety", a score ranging between 20 and 39 indicates mild anxiety, a score ranging between 40 and 59 indicates moderate anxiety, a score ranging between 60 and 79 indicates severe anxiety, and a score of 80 indicates very severe anxiety (Panic).
