What pregnancy does to the spine
Pregnancy is one of the most structurally demanding events the human body goes through. Over nine months, the center of gravity shifts dramatically forward, lumbar lordosis increases, the sacroiliac joints bear substantially more load, and the ligaments throughout the pelvis and spine loosen in response to hormonal changes.
These are not problems — they are normal adaptations to accommodate a growing child. But they create the exact conditions under which vertebral subluxation develops. The spine is shifting and loading in new ways, and misalignment accumulates as it adjusts.
When subluxation is present, the nervous system is working with interference. The nervous system runs everything — including the processes that support a healthy pregnancy. Clearing that interference is what subluxation-based care does.
Left: neutral pre-pregnancy posture. Right: late pregnancy — increased lumbar lordosis, anterior pelvic tilt, and forward center of gravity create the structural conditions for subluxation.
"The body knows how to grow a child. The question is whether the nervous system has what it needs to coordinate that process without obstruction."
How subluxation develops during pregnancy
The structural changes of pregnancy don't happen in isolation. As the lumbar curve deepens and the pelvis tilts forward, the vertebrae above and below adapt — often creating misalignment in the lumbar spine, sacrum, and sacroiliac joints. These are the areas under the most direct mechanical stress during pregnancy.
The cervical and thoracic spine also compensate for the postural shift. A forward center of gravity pulls the head forward and rounds the upper back. Subluxation in the upper cervical spine — already the most neurologically significant region — is common even in patients who had no prior spinal complaints.
By the third trimester, many women have accumulated months of structural change without anyone assessing what that has done to spinal alignment. The nervous system has been adapting the whole time.
Prenatal care at Rochet Family Chiropractic
X-rays are not taken during pregnancy. Prenatal care here is based on postural assessment, motion palpation, and physical examination — the same hands-on analysis used to identify where subluxation is present and how significant it is.
Adjustments during pregnancy use modified techniques and positioning. No prone positioning. No high-force lumbar manipulation. Corrections are specific, gentle, and adapted for each trimester. The principle is identical to every other patient: find the subluxation, correct it precisely, track how the spine responds.
The goal is the same regardless of the patient's age or circumstance: remove the structural interference so the nervous system can coordinate the body's innate processes without obstruction. For a pregnant patient, that matters on behalf of two people.
Sacral and pelvic subluxation
The sacrum and pelvis are under particular stress during pregnancy. The sacroiliac joints — where the sacrum meets the ilium on each side — absorb the transferred load of a shifting center of gravity while the surrounding ligaments are less taut than usual. Sacroiliac subluxation is extremely common in pregnant patients, and it creates nerve interference that travels through the sacral plexus.
Pelvic balance matters structurally during pregnancy for reasons beyond comfort. The uterine ligaments attach to pelvic structures, and a subluxated sacrum or ilium creates asymmetric tension through those attachments. Correcting sacral and pelvic subluxation restores structural balance to the pelvis as a whole.
Left: normal sacrum — pelvic outlet open, fetal head engaged. Right: anterior-inferior sacral subluxation — sacral base rotated forward reduces the outlet's anteroposterior diameter, creating a structural barrier to normal engagement and delivery.
Upper cervical subluxation during pregnancy
Upper cervical subluxation gets less attention in prenatal care than lumbar and pelvic issues, but it is often the most neurologically significant finding. The atlas (C1) surrounds the brainstem — the structure that coordinates autonomic function throughout the body. Subluxation at this level creates interference that extends far beyond the neck.
The postural demands of pregnancy commonly drive upper cervical subluxation by shifting the head forward and compressing the upper cervical joints. Specific upper cervical correction is a core part of care at this practice, regardless of the patient's circumstance.
What the first visit involves
Dr. Rochet has been in practice in Royal Palm Beach since 2007. He sees pregnant patients across all trimesters, from those in the first weeks of pregnancy to those approaching their due date.
Your first visit covers a full health history, postural assessment, and physical examination of the spine. Because X-rays are not taken during pregnancy, the examination is more thorough in other areas — motion palpation, orthopedic testing, neurological evaluation. Dr. Rochet explains exactly what he found before any correction begins.
We're on Royal Palm Beach Blvd, a few minutes from Wellington. Call us or fill out a new patient form to schedule your evaluation.
