The Bonapace Method for reducing pain during childbirth can be used instead of, or in conjunction with, a traditional childbirth education class.
This method does not just teach pain coping techniques, but also teaches about the role of labor pain, how pain messages are transmitted in the body, and three mechanisms that help moderate the perception of pain. Those mechanisms are:
Cognitive structuring / central nervous system control (CNSC). Understanding labor pain and progression – what’s happening and why – enhances a sense of self-control. Focusing on something positive (like a self-affirmation) helps with labor pain.
Gate ControlTheory. Non-painful stimulation blocks part of the pain message transmitted by the spinal cord. Note: Bonapace interprets this differently than I have see elsewhere, saying specifically that it is pleasant sensation applied where the pain is located. The description on their website says “To activate this mechanism during childbirth, the fingers must be run lightly over the painful area, particularly during contractions.”
Diffuse Noxious Inhibitory Control (DNIC). (I call this counter-irritation) Creating a second pain elsewhere on the body (i.e. not where you’re already hurting). The brain wants to reduce the pain’s effect on the body as a whole, so releases endorphins to do so. But the sensations near the second pain are still felt because the body is assessing them. (So, under this theory, holding a birth comb tightly causes a release of endorphins which helps with the labor pain, but the user is still aware of the pressure points from the comb on their palm.) In the Bonapace method, sensitive points on the body (trigger areas) are massaged by the partner, causing pain.
In a journal article (“Evaluation of the Bonapace Method: a specific educational intervention to reduce pain during childbirth”, J Pain Res 6: 653-661 at http://www.dovepress.com/articles.php?article_id=14256), Bonapace et al, compare the results of a “traditional childbirth training program” (TCTP) with the Bonapace method. Study participants chose which class to take from these options.
The TCTP was a 4 week class, with a total of 8 hours of class time, started around the 23rd week of pregnancy. It covered A&P of childbirth, exercises, stages of labor, variations, pain meds and newborn care. Relaxation, visualization, massage, and labor positions were not taught. Only breathing techniques were practiced.
The Bonapace class was 4 weeks, 8 hours, starting in the 30th week. The entire program was dedicated to pain management and partner participation. It covered 1) CNSC through breathing, relaxation, and cognitive understanding of labor pain and endorphins, 2) Gate control – non-painful stimuli such as walking and light back massage between contractions, and 3) DNIC where the partner did painful massage of acupuncture triggers points in the lower back, hands, and buttocks.
39 women participated in the full study. In labor, every 15 minutes, participants were asked to rate their pain on two scales: intensity and unpleasantness. (If pain medications were given, they stopped assessing pain after the medication. If that participant had pain scores for two phases of labor, they were kept in the study, if not, they were dropped.
Those who had learned the Bonapace method had an average of 45% less pain intensity and 47% less unpleasantness than those who had received the “traditional” childbirth education. No difference was found in the use of pain medication.
The reduction in intensity of pain was consistent for nulliparous and multiparous parents. On the “unpleasant” ratings, there was a larger reduction in scores for nulliparous than multiparous. This is likely due to anxiety… a nulliparous woman with no birth experience and no training / childbirth preparation is likely to be anxious about labor pain (and, of course, anxiety increases pain). With the TCTP, her anxiety may have been somewhat reduced and thus her pain unpleasantness would be reduced, but with the Bonapace method, her anxiety and thus unpleasantness were much more reduced.
This study indicates that being given information about the physiology of pain, and plenty of education in clear, simple techniques to manage it, has a significant impact on pain intensity and pain coping.
