This randomized controlled study evaluated whether acupressure applied to the Yintang point during labor affects labor duration, pain, anxiety, and childbirth satisfaction in primiparous women. A total of 104 women were randomly assigned to either the Yintang acupressure group or the sham light-touch control group, with 52 participants in each group.
Participants in the intervention group received five acupressure sessions during labor and the early postpartum period. Participants in the control group received routine midwifery care and light touch at a non-therapeutic forehead location. Labor duration, pain intensity, anxiety, and childbirth satisfaction were compared between the groups.
This study was conducted as a randomized, sham-controlled clinical trial involving primiparous women admitted to the maternity ward of a hospital in eastern Türkiye. The study aimed to evaluate the effects of Yintang acupressure on labor duration, labor pain, postpartum anxiety, and childbirth satisfaction.
A total of 104 eligible participants were randomly assigned in a 1:1 ratio to the intervention group (n=52) or the sham control group (n=52). Participants in both groups received routine midwifery care.
Participants assigned to the intervention group received manual acupressure at the Yintang point, located on the midline of the forehead between the eyebrows. Five sessions were administered: at 5-6 cm cervical dilation, at 6-7 cm cervical dilation, at approximately 8 cm cervical dilation, during the third stage of labor, and 60 minutes after childbirth. Each session lasted approximately 6-7 minutes.
Participants in the sham control group received light touch at a forehead location outside the Yintang point. The duration, participant position, and practitioner contact were designed to resemble the intervention procedure without applying therapeutic pressure to the Yintang point.
Labor duration was recorded using a labor monitoring form. Pain intensity was evaluated using the Visual Analogue Scale at prespecified assessment points. Anxiety was assessed using the Beck Anxiety Inventory, and childbirth satisfaction was assessed using the Birth Satisfaction Assessment Form after childbirth.
Because participant recruitment and data collection had been completed before submission of this record, the study was registered retrospectively.

Participants received routine midwifery care and manual acupressure at the Yintang point. Five sessions were administered: at 5-6 cm cervical dilation, at 6-7 cm cervical dilation, at approximately 8 cm cervical dilation, during the third stage of labor, and 60 minutes after childbirth. Each session lasted approximately 6-7 minutes.
Other: Yintang Acupressure
Participants received routine midwifery care and light touch at a forehead location outside the Yintang point. The sham procedure was administered at the same assessment periods and for approximately the same duration as the Yintang acupressure intervention, without applying therapeutic pressure to the Yintang point.
Other: Sham Light Touch
Manual pressure was applied to the Yintang point at 5-6 cm, 6-7 cm, and approximately 8 cm cervical dilation, during the third stage of labor, and at 60 minutes postpartum. Each session lasted approximately 6-7 minutes.
Light touch was applied at a non-therapeutic forehead location at the same assessment periods and for approximately the same duration as the experimental intervention, without therapeutic pressure at the Yintang point
Labor Pain Intensity
Labor pain intensity was assessed using the Visual Analogue Scale (VAS), ranging from 0 to 100 mm. A score of 0 indicated no pain, and a score of 100 indicated the worst imaginable pain. Pain was assessed at prespecified stages during labor and at 60 minutes postpartum.
Time frame: From enrollment at 5-6 cm cervical dilation through 60 minutes postpartum
Postpartum Anxiety
Anxiety was assessed using the 21-item Beck Anxiety Inventory. Each item is scored from 0 to 3, producing a total score ranging from 0 to 63. Higher scores indicate greater anxiety.
Time frame: At 60 minutes postpartum
Plan to share: No — Individual participant data will not be shared because the informed consent obtained from participants did not include permission for public or third-party sharing of individual-level data. Aggregate study findings will be reported in scientific publications.

Ran from Jun 2024 to primary completion in Apr 2025, 10 months.
Of 191 non-industry interventional studies with no phase under Labor Pain, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 14. This study's 10 months is above that.
Counting every sponsor, half of 193 studies reached it within 9 months; a quarter within 5 and three quarters within 14.
