A Webster certified chiropractor is a licensed chiropractor who has completed specialized training in the Webster Technique, a specific pelvic adjustment designed primarily for pregnant women. The certification is granted by the International Chiropractic Pediatric Association (ICPA) after a chiropractor completes a 13-hour seminar and passes both a hands-on practical exam and a written exam. While the technique is most closely associated with pregnancy care and fetal positioning, it was originally developed for all weight-bearing individuals regardless of age or gender.
What the Webster Technique Actually Does
The Webster Technique targets the sacrum, the triangular bone at the base of your spine that connects to your pelvis through the sacroiliac (SI) joints. When these joints become restricted or misaligned, the surrounding muscles and ligaments tighten unevenly, which can affect how the entire pelvis functions. During pregnancy, this matters because a misaligned pelvis can reduce the space available for the baby to move and grow.
A Webster adjustment addresses this in stages. First, the chiropractor identifies which side of the sacrum is fixated and performs a gentle adjustment, typically using a drop-piece built into the chiropractic table. Next, they release tight muscles and ligaments on the back of the pelvis, most commonly the piriformis muscle and the sacrotuberous ligament. Finally, with you lying on your back, they assess and work on the round ligament, the psoas muscle, and sometimes the pubic symphysis at the front of the pelvis. The entire goal is to restore balanced movement so the pelvis can function without pulling or restricting on one side.
How Certification Works
To earn Webster certification, a chiropractor must attend the ICPA’s full “Perinatal Care with Webster Certification” seminar, which runs 13 hours. The seminar covers the specific analysis protocol, the hands-on adjustment technique, and the soft tissue work that accompanies it. At the end, chiropractors take an on-site practical exam where they demonstrate the technique and an online written exam covering the material. Both exams must be passed to receive certification. Chiropractic students can attend the seminar but must upgrade to full doctor of chiropractic status and complete the written exam after graduation.
This certification signals that a chiropractor has gone beyond their standard doctoral training to learn a technique specifically designed for the biomechanical demands of pregnancy. Not every chiropractor who treats pregnant patients holds this credential, and not every chiropractor with the credential limits their practice to pregnant patients.
The Connection to Breech Babies
The Webster Technique gets the most attention for its association with breech positioning. The logic is straightforward: when the pelvis is misaligned, the muscles and ligaments attached to the uterus can create what’s called intrauterine constraint, meaning external forces limit the baby’s ability to move freely. If the baby can’t move, it may not be able to turn head-down on its own, which can lead to a cesarean delivery.
In a survey published in the Journal of Manipulative and Physiological Therapeutics, ICPA chiropractors reported that 92% of breech cases they treated with the Webster Technique resolved, with the baby turning to a head-down position. The surveyed doctors reported an overall 82% success rate in relieving the musculoskeletal causes of intrauterine constraint. The study’s authors noted that the technique appeared most beneficial in the eighth month of pregnancy, a window when breech babies are unlikely to turn on their own and when external cephalic version (where a doctor manually pushes on the abdomen to rotate the baby) tends to be less effective.
It’s worth understanding what the technique does not do: the chiropractor never directly moves the baby. The adjustment works on the mother’s pelvis, and when the constraint is relieved, the baby has more room to reposition naturally. This makes it considerably gentler than external cephalic version, which involves applying pressure directly to the abdomen.
What to Expect at an Appointment
If you’ve never been to a chiropractor during pregnancy, the setup looks a little different from a standard visit. You’ll be given a special pregnancy pillow with a cutout in the center so you can lie face down comfortably without putting pressure on your belly. Some offices have tables with a drop-down section that creates additional space. The adjustment itself uses either the drop table mechanism or a gentle adjusting instrument, and the force involved is relatively light compared to many standard chiropractic adjustments.
A typical session covers the sacral adjustment, the soft tissue work on the back of the pelvis, and then the round ligament and muscle assessment on the front. The whole process is quick, usually fitting within a standard chiropractic appointment length.
How Often Pregnant Women Typically Go
Visit frequency generally increases as pregnancy progresses. During the first trimester, most women see a chiropractor every two to four weeks. In the second trimester, that often shifts to once per week or every two weeks as the body’s center of gravity changes and pelvic demand increases. By the third trimester, weekly visits are common, particularly for women working with a Webster-certified provider to optimize pelvic alignment before labor.
A narrative review in the Journal of Chiropractic Medicine reported that first-time mothers who received chiropractic care throughout pregnancy experienced labor times that were 25% shorter on average. Women who had given birth before and received chiropractic care saw a 31% reduction in average labor time. These figures reflect general chiropractic care during pregnancy, not the Webster Technique in isolation, but pelvic alignment is a central component of that care.
Beyond Pregnancy
Although the Webster Technique is overwhelmingly associated with prenatal care, the ICPA emphasizes that it was always intended as a sacral analysis and adjustment for any weight-bearing person. The SI joints and surrounding soft tissues can become restricted in anyone, whether from injury, repetitive motion, or postural habits. Some Webster-certified chiropractors apply the same analysis framework to non-pregnant patients dealing with lower back pain, pelvic instability, or hip discomfort. The certification, however, specifically trains practitioners in the perinatal context, so its primary clinical application remains pregnancy-related.
