During the active phase, the pregnant woman was asked to manage the mechanical massage cushion and massage the desired areas at the desired intensity until the end of the phase. Pain scales (VAS, VCS) were administered to the pregnant women at the end of the latent (when cervical dilation is 3 cm) and active phases (when cervical dilation is 8 cm). The Childbirth Comfort Questionnaire was administered at the end of the first hour after birth.

Standard care was applied to the control group. Pain scales (VAS, VCS) were administered to the pregnant women at the end of the latent (when cervical dilation is 3 cm) and active phases (when cervical dilation is 8 cm). The Childbirth Comfort Questionnaire was administered at the end of the first hour after birth.

The mechanical massage cushion was introduced to the pregnant woman and its use was explained. In addition to routine hospital procedures, during the latent phase, a custom-made bed protector and towel were placed on the mechanical massage cushion, and the researcher accompanied the pregnant woman during the first massage application. The bed protector and towel were changed as needed when soiled. During the active phase, the pregnant woman was asked to manage the mechanical massage cushion and massage the desired areas at the desired intensity until the end of the phase. Pain scales (VAS, VCS) were administered to the pregnant women at the end of the latent (when cervical dilation is 3 cm) and active phases (when cervical dilation is 8 cm). The Childbirth Comfort Questionnaire was administered at the end of the first hour after birth.

Childbirth Comfort Questionnaire (CCQ): The scale was developed by Schuiling in 2003. The Turkish validity and reliability of the scale were examined by Coskuner et al. in 2015. The scale is a 5-point Likert-type instrument, consisting of 9 items and 3 sub-dimensions. The minimum score is 9 and the maximum score is 45. A high score indicates high comfort.

Visual Analog Scale (VAS): It is a scale where painlessness and unbearable pain are indicated on a 10 cm ruler, and the individual marks the pain they perceive. When evaluating the scale, the distance between the beginning and the marked part is measured with the ruler and the distances are determined as 0-2 cm; 3-4 cm; 5-6 cm; 7-8 cm and 9-10 cm and should be interpreted as no pain; mild pain, moderate pain; severe pain and unbearable pain, respectively.

Verbal Category Scale (VCS): It is a one-dimensional scale that defines the severity of pain. Pain is divided into categories from mild to unbearable. The individual marks the part of the scale that corresponds to their pain.
