Chiropractic care during pregnancy, often referred to as prenatal chiropractic, is a common approach women use to manage physical discomforts as the body changes. This care is widely regarded as a safe and beneficial therapy for expectant mothers when performed by a trained professional. Adjustments help maintain proper spinal and pelvic alignment, which may alleviate issues like back pain and sciatica. Timely communication between the patient and the provider is necessary to ensure the safety and appropriateness of treatment throughout gestation.
The Critical Timing of Disclosure
The moment a pregnancy is suspected or confirmed, even in the very early stages, the chiropractor should be notified immediately. Waiting until the physical changes of the second or third trimester become visually apparent is too late for optimal risk management. Early disclosure is necessary because the first trimester, covering the initial twelve weeks, is a time of rapid embryonic and fetal development.
A pregnant patient’s file must be updated before any session to screen for therapies inappropriate for pregnancy. Modalities like electrical stimulation, therapeutic ultrasound, or heat therapies applied directly to the low back and abdomen are contraindicated. These therapies carry a risk of inducing uterine contractions or affecting the developing fetus and must be avoided.
Providing this information upfront allows the chiropractor to immediately modify the treatment plan and avoid potentially harmful procedures. Notification also allows the chiropractor to begin planning for the physiological adaptations that will soon affect the patient’s body mechanics. Proactive modification ensures that the care provided is tailored to the unique and rapidly changing needs of the pregnant body from the earliest possible point.
Physical Changes Requiring Treatment Modification
The body undergoes transformation during pregnancy, driven by hormonal shifts and the mechanical presence of the growing fetus. One significant change is the release of the hormone relaxin, which begins to circulate in high concentrations early in gestation. Relaxin’s primary function is to soften ligaments throughout the body, particularly those in the pelvis, to prepare for childbirth.
This ligamentous laxity means that joints are inherently less stable, fundamentally altering how a chiropractor must deliver an adjustment. Adjustments must be performed with less force and gentler movements to avoid overstretching hypermobile joints. The pelvis, especially the sacroiliac joints, becomes susceptible to misalignment, often necessitating specific, gentle techniques like the Webster Technique to maintain balance.
As the pregnancy progresses and the uterus expands, the patient’s center of gravity shifts forward and upward. To compensate for this mechanical imbalance, the spine naturally increases its curvature in the lower back, known as increased lumbar lordosis. This exaggerated curve places stress on the spinal joints and surrounding muscles, leading to common discomforts like low back pain and sciatic nerve irritation.
To accommodate the growing abdomen and avoid pressure on the fetus, the chiropractor must modify patient positioning and equipment. After the first trimester, lying face-down (prone position) on a standard adjustment table is no longer safe or comfortable. Instead, specialized chiropractic tables with abdominal cutouts or drop sections are used, or the patient is positioned in a modified side-lying position for necessary manipulations.
Conditions That May Temporarily Prevent Adjustment
While chiropractic care is generally safe during a healthy pregnancy, certain medical conditions or complications serve as contraindications to spinal manipulation. These conditions require immediate medical attention and clearance from an obstetrician before any further chiropractic adjustment can be performed. The chiropractor must screen for these conditions during the patient intake process.
Examples of absolute contraindications include unexplained vaginal bleeding or spotting, which can signal a serious complication like placental abruption or placenta previa. An ectopic pregnancy, where the fertilized egg implants outside the uterus, also prevents chiropractic adjustment due to the risk of rupture.
Conditions associated with severe high blood pressure, such as preeclampsia, also preclude the use of spinal manipulation until the condition is medically managed. If a patient reports sudden, severe pelvic pain or suspects that their amniotic membranes have ruptured, the session must be immediately stopped. In these situations, the chiropractor’s role shifts to referring the patient back to their primary obstetric provider for a medical evaluation.
