Chiropractic Care in Pregnancy: Part One


Many people experience back and pelvic pain in pregnancy.

For some this is just a passing phenomenon, a little discomfort that goes along with the hormones of pregnancy relaxing the pelvis and helping it expand for the birth. Some mild back and joint discomfort is common in pregnancy and does not have to be a problem.

For others, however, back and joint pain becomes a significant and long-lasting problem that can become debilitating. Some find it difficult to turn over in bed, to get dressed in the morning, to walk any distance, or even to sit comfortably for long. Some are in constant pain from it; a few even end up using a walker or in a wheelchair, unable to walk without aid.

Fortunately, chiropractic care is often helpful in these cases. Many pregnant people report pain relief and more mobility with chiropractic care. Yet some are not sure about the wisdom of chiropractic care in pregnancy.

Here are some answers to the most common questions about chiropractic care for pregnancy, and help in finding a pregnancy chiropractor for those who want it.

Purpose of Chiropractic Care During Pregnancy


While many doctors say that back and pelvis pain is "normal" in pregnancy and there is nothing that can be done to help it, chiropractors do not believe that significant or long-lasting pain is "normal" at all, and they know from experience that much of it can be helped.

They believe pain occurs when the spine or pelvis are out of alignment or the muscles and soft tissues around them are unbalanced. This can present as back pain, pain in the buttocks that radiates down the leg (sciatica), pubic symphysis pain in the front of the pelvis, hip pain, tailbone (coccyx) pain, stabbing pains in the abdomen when the mother moves too quickly or sneezes (round ligament spasm), neck pain, difficulty walking, difficulty turning over or lifting one leg, difficulty getting in and out of cars, and sometimes shoulder or rib/side pain.

If you are experiencing this kind of pain in pregnancy, chiropractic care may help make pregnancy more comfortable. Chiropractors believe that chiropractic care can help pregnant people in several different ways:
  • By creating more room in the pelvis for baby to maneuver through
  • By improving nerve function so that contractions are more effective
  • By relieving imbalances or tensions in the ligaments and soft tissues supporting the uterus
The most basic component of chiropractic care is to make sure the bony passage around the baby (the pelvis) is as open and well-aligned as possible, creating the largest possible space for the baby to move through.

Many women who have had cesareans have been told that their "sacrum is too prominent" or "too flat," that their pubic arch is "too flat/narrow," that "there is a bone in the way," or simply that their "pelvis is too small/narrow" for a baby to maneuver through. However, after chiropractic care, many of these same women have gone on to give birth to bigger babies than their "stuck" cesarean babies, simply because the pelvic passage is now optimized and the baby has more room. It doesn't seem like such treatment would make much more space, but getting into good alignment can actually make enough difference to maximize the space and help make an easier birth.

Chiropractors also place great importance on good nerve function. They believe that a misaligned spine impedes nerve function. They believe that poor alignment can not only affect the body physically by making less room for the baby to get out, but also by causing ineffective, uncoordinated contractions because of poor nerve function. From his article on "The Safety of Chiropractic Care in Pregnancy," Dr. Jason Lindekugel (D.C.) writes:
Chiropractic manipulation seeks to balance the joints of the body in order to normalize nerve function...In restoring joint function, chiropractors are relieving nerve irritation which in turn relaxes muscles and the ligaments of the pelvis and uterus. So, proper nerve function is the goal, not just “cracking” joints.
Finally, chiropractors believe that by relieving any misalignments, they will create more space and improve nerve function, lessening the risk for dystocia (slow, unproductive labors) and hopefully resulting in safer, faster, and more effective labors and births.

Some people mistakenly think that chiropractors are practicing obstetrics and manually trying to turn babies into position. This is not true. Chiropractors are trying to create conditions to normalize the body's functions so the mother has the best possible chance at an effective labor and birth.

Effectiveness of Chiropractic Care in Pregnancy

But is seeing a chiropractor in pregnancy that helpful? What does the research say?

Traditionally, chiropractors have done research differently than mainstream medicine. They have  relied more on case reports and case series rather than gold-standard randomized studies. They often didn't use control groups because they were loathe to deny anyone care, especially in pregnancy. Even when mainstream studies were done, sample sizes tended to be small. So there are limits to many studies done in the past.

However, there are now a number of studies and reviews using more rigorous methodology that are reassuring. Here is a summary of a few.

A 2013 prospective randomized study in pregnant patients with low back and pelvic pain compared usual obstetric care with obstetric care plus additional chiropractic care. It found that those patients who received the additional chiropractic care improved significantly, while those who received just standard obstetric care did not improve at all.

A 2014 study found that the improvement from chiropractic care was long lasting. Nearly 90% of study participants were improved a year later. Several other studies (see references below) have also found significant improvement with chiropractic care in pregnancy, with few adverse events.

A 2012 Canadian review stated:
Massage therapy and chiropractic care, including spinal manipulation, are highly safe and effective evidence-based options for pregnant women suffering from mechanical low back and pelvic pain.
In 2015, the Cochrane Collaboration, a leader in evidence-based care, reviewed a series of studies on alternative care practices in pregnancy like acupuncture, craniosacral therapy, and osteomanipulation (basically chiropractic care). They found the quality of evidence "moderate," and that osteomanipulative therapy did significantly  reduce low back and pelvic pain in pregnancy. Furthermore, any adverse events were "minor and transient."

It should be noted that no matter what the research says, some people will never be comfortable trying chiropractic care, and that's okay. If chiropractic care is not for you, don't feel pressured into it. Women have been having babies for thousands of years without having chiropractic care. Most will do fine without it. However, if you are having lots of back pain or pelvic pain, you might want to reconsider it.

If you are still not sure, you might try exploring the possibility further without committing to it. Ask local midwives and doulas for recommendations of good pregnancy chiropractors, then call and ask if you can do a non-treatment consult about your case. Find out how the chiropractor makes room for the pregnancy belly during treatment and the techniques they might use. See if you can observe treatment during an appointment (if the patient gives permission). Often this is enough to reassure people that chiropractic care in pregnancy is reasonable and safe. However, whatever you decide, remember that it's always your choice.

When To See a Chiropractor and How Often

If you do decide to see a chiropractor in pregnancy, one common question is when to start seeing them and how often. Unfortunately, there is no simple answer to this. The answer totally varies from woman to woman, depending on each person's unique needs.

Ideally, people would start seeing a chiropractor before or between pregnancies so that any serious issues can be taken care of before the hormones of pregnancy start softening and loosening the ligaments, making it hard to maintain chiropractic adjustments. The more serious a person's issues, the smarter it would be to start care before pregnancy instead of waiting till after they are pregnant.

However, many people only start experiencing significant pain once they are already pregnant. Others may have limits on the amount of chiropractic visits that are covered under their insurance, or they have no chiropractic coverage and must pay cash. Therefore, many want to try and maximize the benefit of the visits by timing them carefully, and that may mean limiting them to pregnancy only, or even to the last third of pregnancy only.

The problem is that no two people's problems are alike, and there is no one prescription that fits all everyone's needs. The loosening hormones of pregnancy increase as pregnancy progresses, so generally speaking it's better to start treatment sooner than later. However, if you have only a few visits that are covered by insurance or you have limited ability to pay for them out-of-pocket, then you may want to save your visits for the third trimester. However, if you do this and you have really significant alignment issues, you also run the risk of not getting enough treatment to really fix the problem in time. So there is no one answer for every woman. It really depends on the unique circumstances of your particular situation. If you are in a significant amount of discomfort, that usually indicates a problem that should be addressed sooner than later.

Generally speaking, chiropractors prefer to see women before they become pregnant to start resolving any long-standing misalignment issues. Once you become pregnant, most chiropractors want to see you on the same approximate schedule that a doctor or midwife sees you, which is about once a month in the first 2 trimesters, bi-weekly in weeks 32-36, and every week after 36 weeks until the baby is born.

Now obviously, that's the ideal schedule. A lot depends on what's happening with the body. If a pregnant woman comes in as a new patient and has a lot of major alignment issues going on, most chiropractors are going to want to see her weekly (or more) until her alignment issues are better, and then they will go back to the standard schedule noted above.

Other women may not need to be seen even every month. If the chiropractor finds that there is nothing to adjust, then he/she should send you home and elongate the time between visits. Some lucky women find that their pain goes away after a couple of chiropractic treatments and then they're done and never need to go back.

On the other hand, some women need to visit more often than weekly. When treatment is first initiated, frequent visits are important to start retraining the body's muscles and ligaments to "remember" the new alignment consistently. So there may be a flurry of frequent visits in the beginning that slowly space out farther and farther as the woman's body adapts to the new patterns, and then visit frequency comes and goes, depending on the woman's needs. In women with a history of major alignment issues, it's not unusual for the woman to go back to seeing the chiropractor very frequently near the end of pregnancy because the ligaments are so loose by then that it's difficult to maintain any adjustments. It all depends on the needs of the woman and her comfort levels.

However, a chiropractor should not force you to buy a pre-packaged bundle of "x" amount of visits for "x" cost. Some doctors offer this as a way for patients to save money, but the package should be flexible so that if you didn't end up needing "x" amounts of visits, you wouldn't have to have them. Furthermore, a pre-defined schedule of visits cannot anticipate what your body will need and how it responds to treatment; for some people more frequent visits might be needed, while others may need much less. A "one size fits all" package is a sign you should seek out a different chiropractor instead.

Unfortunately, there are bad chiropractors/quacks out there, just as there are quack doctors. Because of this, some people reject all chiropractors altogether. But the reasonable response to quack doctors is not to ignore all medical advice and shun all doctors, but instead to find a better, reputable doctor, one whose treatment philosophy and methods align with your preferences.

The same goes for chiropractors. If you find a bad one, don't be afraid to leave and try another one. Get recommendations from other mothers or childbirth professionals to help guide you to the more reputable and helpful practitioners. Also, there are many different styles of chiropractic care and ways to adjust people. If you don't like one style, keep trying till you find a chiropractor that uses techniques you are comfortable with and seems to "get" your particular body needs. Listen to your instincts; if your intuition is saying that a particular chiropractor is not for you, then find a new one.

Fortunately, most chiropractors are legitimate professionals and are not just out to make a quick buck. They should evaluate your condition, suggest a plan of care, and then keep re-evaluating your need for visits based on how well you respond to treatments. Their care plan should be dynamic and changing in response to your own needs and comfort.

In short, there is no one pattern of visits that you "should" follow. Ideally, you should try to start chiropractic care before pregnancy, and then in pregnancy see the chiropractor monthly, then bi-weekly, then weekly in the last month. However, this schedule is not set in stone and should be adjusted to the unique needs of each person.

Summary

To summarize, the purpose of chiropractic care during pregnancy is to:
  • Keep the body well-aligned to make the maximum possible space available for baby to pass 
  • To optimize nerve function so that contractions can be effective and coordinated
  • To balance joints, ligaments, and muscles of the uterine supporting structures so baby has the best chance to assume the easiest possible position for being born 
In other words, chiropractic care during pregnancy may help pregnancy be more comfortable, and hopefully help labor and birth be easier for mother and baby. Although further research is needed, the research we have so far suggests that chiropractic care in pregnancy can be very helpful for low back and pelvic pain.

...We examined whether a multimodal approach of musculoskeletal and obstetric management (MOM) was superior to standard obstetric care to reduce pain, impairment, and disability in the antepartum period.  STUDY DESIGN: A prospective, randomized trial of 169 women was conducted. Baseline evaluation occurred at 24-28 weeks' gestation, with follow-up at 33 weeks' gestation.... Both groups received routine obstetric care. Chiropractic specialists provided manual therapy, stabilization exercises, and patient education to MOM participants. RESULTS: The MOM group demonstrated significant mean reductions in Numerical Rating Scale scores (5.8 ± 2.2 vs 2.9 ± 2.5; P < .001) and Quebec Disability Questionnaire scores (4.9 ± 2.2 vs 3.9 ± 2.4; P < .001) from baseline to follow-up evaluation. The group that received standard obstetric care demonstrated no significant improvements. CONCLUSION: A multimodal approach to low back and pelvic pain in mid pregnancy benefits patients more than standard obstetric care.

...This retrospective case series was undertaken to describe the results of a group of pregnant women with low back pain who underwent chiropractic treatment including spinal manipulation. Seventeen cases met all inclusion criteria. The overall group average Numerical Rating Scale pain score decreased from 5.9 (range 2-10) at initial presentation to 1.5 (range 0-5) at termination of care. Sixteen of 17 (94.1%) cases demonstrated clinically important improvement. The average time to initial clinically important pain relief was 4.5 (range 0-13) days after initial presentation, and the average number of visits undergone up to that point was 1.8 (range 1-5). No adverse effects were reported in any of the 17 cases. The results suggest that chiropractic treatment was safe in these cases and support the hypothesis that it may be effective for reducing pain intensity.
