The Webster Technique is a chiropractic adjustment focused on the sacrum and pelvis, used primarily during pregnancy. It aims to correct misalignments in the sacral joint that may restrict the uterus and surrounding ligaments, potentially influencing fetal positioning. Most people searching for this term are pregnant, have been told their baby is breech, and want to understand what this technique actually involves.
How the Technique Works
The sacrum is the triangular bone at the base of your spine, wedged between your two hip bones. During pregnancy, hormonal changes loosen the joints in this area, and the growing weight of the uterus shifts your center of gravity. This combination can cause the sacroiliac (SI) joint to move out of its normal alignment, creating tension through the pelvis.
The Webster Technique addresses this through two components. First, the chiropractor performs a specific adjustment to the sacrum to restore SI joint function. Second, they use gentle soft tissue work on the ligaments and muscles connected to the pelvis and uterus. The key structures involved include the round ligament (which connects the uterus to the pubic area), the broad ligament (which anchors the uterus to the pelvic walls), and the psoas muscle (a deep hip flexor that runs along the lower spine). Tension in the gluteal and piriformis muscles, which often shows up as sciatic-type pain during pregnancy, is also addressed.
The theory is straightforward: when the sacrum is misaligned, it creates uneven tension on these ligaments and muscles, which can pull on the uterus and restrict the space available to the baby. By restoring balance to the pelvis, the technique removes that excessive pull and gives the baby more room to move freely.
The Connection to Breech Babies
The Webster Technique is most commonly discussed in the context of breech presentation, where the baby is positioned feet-first or bottom-first instead of head-down. The technique is not a direct repositioning of the baby. Instead, it targets what chiropractors call “intrauterine constraint,” the idea that musculoskeletal imbalances in the pelvis physically limit how the baby can move and settle into position.
By relieving that constraint through sacral adjustment and light massage of the lower abdominal area, the technique theoretically allows the baby to turn head-down on its own. The International Chiropractic Pediatric Association (ICPA) positions it specifically as a pelvic balancing technique rather than a breech-turning procedure, though the two are closely linked in practice.
The technique is typically used around the eighth month of pregnancy, when breech presentation becomes a concern. In a survey of ICPA chiropractors who use the technique, 92% of breech cases reportedly resolved to a head-down position. That number comes from practitioner self-reports rather than a controlled clinical trial, so it should be interpreted with some caution. No large randomized studies have confirmed these results, though case reports in chiropractic journals describe successful outcomes.
What a Session Feels Like
If you’re imagining a forceful back-cracking session, the reality is much gentler. The adjustment is performed on a specialized chiropractic table with a drop-away abdominal section, so you can lie face down comfortably without any pressure on your belly. The chiropractor applies gentle, targeted pressure to the sacrum using the table’s drop mechanism, which absorbs most of the force. The soft tissue portion involves light touch along the lower abdomen and pelvic ligaments.
Sessions are typically short. Many women report the adjustment itself taking only a few minutes, though the initial visit includes an assessment of pelvic alignment and pregnancy history. Some chiropractors recommend visits once or twice per week in the weeks leading up to the due date, depending on how the pelvis responds.
Beyond Breech: Pelvic Pain and Comfort
While breech presentation gets the most attention, many pregnant women seek the Webster Technique for general pelvic and low back pain. The same SI joint dysfunction that can restrict fetal movement also causes significant discomfort. Pain in the lower back, hips, and the sciatic nerve pathway is extremely common during the third trimester, and much of it traces back to the pelvis.
Restoring sacral alignment can reduce strain on the piriformis and psoas muscles, which are frequent culprits in pregnancy-related sciatic pain. Some women also find that better pelvic balance makes labor and delivery more comfortable, though evidence for this is largely anecdotal.
Finding a Certified Practitioner
Not every chiropractor is trained in this technique. Webster Certification requires completing a 13-hour perinatal care seminar through the ICPA, passing both a hands-on practical exam and a written exam, and maintaining active ICPA membership. The chiropractor must also be in good standing with their regional licensing board. The ICPA maintains a directory of certified practitioners on their website, which is the most reliable way to find someone with specific training.
Certification matters here because the technique involves working with pregnant patients who have unique anatomical considerations. A chiropractor trained in general spinal adjustments may not have the specialized knowledge to safely and effectively work with the changing pelvis during pregnancy. When searching for a provider, asking specifically about Webster Certification (not just general prenatal chiropractic experience) is a useful distinction.
