Chiropractic care in pregnancy is vital to the normal physiological function of both the mother and baby throughout pregnancy and birth. More women and birth providers are discovering the many benefits associated with chiropractic care in pregnancy. The Webster Technique is a specific chiropractic sacral analysis and diversified adjustment. The goal of the adjustment is to reduce the effects of sacral subluxation/ SI joint dysfunction. In doing so, neuro-biomechanical function in the pelvis is facilitated.


There is a thick round ligaments that encircle the uterus, connecting the front part of the uterus to the groin, where your legs meet your pelvis. They normally tighten and relax slowly. As your baby grows during pregnancy the uterus expands to accommodate.  These round ligaments are stretched with the increase in size and weight of the baby (a normal part of pregnancy) often causing them to become strained. Sudden movements can cause them to tighten quickly. This is what causes the shooting abdominal pain that usually lasts a few seconds.

The stretching and straining of the round ligament and your expanding belly can cause not only pain but alterations in the alignment of your spine and pelvis. Because of how the pelvis and sacrum are set up, if one of your hip bones rocks back into misalignment and the opposite hip bone rocks forward, the sacrum, which connects those two hip bones, can tilt back one way or the other way. This pulls on the round ligaments of the uterus that is attached to the pelvic wall. As you progress through pregnancy, those ligaments strain and tighten like a pulled rubber band.

Sacral subluxations may contribute to difficult labor for the mother (i.e., dystocia), caused by inadequate uterine function, pelvic contraction, and baby mal-presentation. Correction of sacral subluxations and round ligament tension may have a positive effect on all of these causes of dystocia.


The Webster Technique has become a familiar term in the pregnancy and birth conversation. Families are seeking out chiropractors who are proficient in this technique as a way to support a more comfortable, safer, and easier birth.


Dr. Larry Webster, founder of ICPA (International Chiropractic Pediatric Association) developed the Webster Technique in response to his daughter, Lucinda’s birth to her daughter, Shannon. Dr. Webster was present at her long and arduous birth and although he adjusted her during the birth, he felt that chiropractic could have a bigger impact in labor with a more specific approach to the pelvis.

After this personal experience with his daughter’s birth, Dr. Webster strove to develop an adjustment “for laboring women to help with the ease of birth.” He felt that there must be a more specific way of addressing subluxations throughout pregnancy that would contribute to safer, easier births for the mother.

Shortly after, Dr. Webster was caring for a family whose mother was pregnant and also presenting breech. He applied his newly discovered approach in hopes of an easier delivery than his daughter had. He saw her once per week for several weeks and they noticed that her baby turned vertex in time for delivery.

Dr. Webster began teaching other chiropractors this adjustment. These doctors reported that when their patient’s babies were not in an optimal position, these babies were turning vertex as well. Thus the title: “Webster Breech Turning Technique” later to be called the “Webster In-Utero Constraint Technique” by Drs. Anrig and Forrester.

When his daughter, Pamela, was pregnant, he insisted that she get regular chiropractic care throughout pregnancy and mailed her a video of his technique to show her chiropractor. She also showed it to her OB, who was quite interested in the pelvic biomechanics and the chiropractic perspective. He too, encouraged her to see her chiropractor regularly for this technique knowing this was out of his obstetric scope.
