Back pain during the childbearing year affects up to 80% of women as a result of the vast changes happening in the body as the baby grows. During pregnancy, the joints throughout the body become more mobile due to the production of several hormones. The spine is therefore more easily sprained or pulled into sub-optimal alignment. This can result in muscle spasm, inflammation, pain, and a decrease in functional and recreational activities. In addition, women gain on average 25-35 pounds over a short period of time, with the majority of that weight distributed at the abdomen and breasts. This change in her shape shifts the woman’s center of gravity forward and upward, resulting in changes in her posture. She tends to stand with an excess arch in her lower back and her upper back rounded forward. These postural changes place stress on the muscles and ligaments surrounding the spine which can also lead to pain and functional limitations. Although back pain during pregnancy is a common problem, it often goes untreated as it is often perceived as an inevitable side effect of pregnancy.
Research findings suggest that the majority of cases of pregnancy-related back pain go unreported, with only a third of women discussing the problem with their maternity providers. Within that group, only 25% of their providers recommended a specific form of treatment.1 Women do not, however, have to suffer through their pregnancies with back pain. There are several safe, effective treatments that can help them manage their pain and optimize their well-being throughout pregnancy and into the postpartum period. A description of each follows, as well as some pros and cons.
Independent Exercise Program
Exercise is beneficial in preventing back pain, as well as helping to manage and reduce existing pain. In fact, research findings suggest that regular exercise during pregnancy can result in a significant reduction in the intensity of back pain. 2,3 Achieving a good balance between the strength and flexibility of the muscles surrounding the spine and pelvis can help provide stability and decrease the risk of injuries. In particular, the abdominal, back, and pelvic floor muscles should be targeted, as they are often most impacted by the physical changes that occur during pregnancy. Prenatal fitness classes offer a nice way for women to improve their cardiovascular fitness, strength, and flexibility, with the added benefit of socializing with other women. Prenatal yoga and Pilates are nice options as they target the spinal stabilizing muscles while focusing on alignment and posture. If such classes are not accessible or affordable, there are numerous book and video resources that can help women design their own programs.
Pros:
- May help prevent pain
- Can do exercise when it’s convenient
- Inexpensive
- Can use as an adjunct to individualized treatments for optimal results
Cons:
- If exercises are done incorrectly, pain and injury could result
- If lacking motivation, women may not be consistent with an exercise program
- Exercise may not be suitable for women with high risk pregnancies
If attempts to exercise independently are unsuccessful or pain initially prohibits exercise, individualized treatment by one of the following professionals could be beneficial.
Physical Therapy
A physical therapist experienced in treating pregnant women can evaluate the woman’s posture, spinal and pelvic alignment, joint mobility, muscle flexibility, strength, and tone. The physical therapist can perform safe, gentle techniques to re-align joints, improve joint motion, and reduce muscle spasm. In addition, a physical therapist can design an exercise program specific to the client’s needs in terms of muscle strength and flexibility, as well as teaching her how to move, position herself during sleep, and optimize her posture during daily activities. The treatment modalities physical therapists commonly use, including ultrasound and electrical stimulation, are for the most part contraindicated during pregnancy, but moist heat or cold packs could be used to help reduce pain and spasm.
Pros:
- Postural re-training will help during pregnancy and throughout motherhood to decrease stress to the spine, thereby decreasing risk of injury
- The pregnant woman can stop seeing the physical therapist and continue independently with her individually designed exercise program once she is ready
- Most health insurance covers the cost of physical therapy minus a co-payment
Cons:
- Depending on the facility, patients may not receive one on one treatment
- Not all therapists are experienced in treating pregnant women, so it is advised to inquire with local facilities to find an experienced provider
Massage Therapy
A massage therapist trained in prenatal massage will evaluate the client’s muscle tone and address any areas of tightness or restriction. The pregnant woman may be treated on her side, and some massage therapists use special pillows with a cutout for the abdomen so the woman can lie on her belly. Using various techniques, the massage therapist can help improve the circulation to the muscles, reduce stress, and promote relaxation, which can in turn improve posture. One study also found that pregnant women receiving massage therapy for 20 minutes twice a week experienced less anxiety, improved mood, better sleep, and a reduction in back pain.4
Pros:
- Improves circulation to muscles in pain or spasm
- Promotes relaxation and improved posture
- Gives the pregnant women an opportunity to rest and unwind, which is often much needed
Cons:
- Can be costly, even if subsidized by insurance
- Without exercise to help address muscle weakness and inflexibility, relief may be temporary
- As with physical therapists, one should find a massage therapist trained in prenatal massage
Chiropractor
A chiropractor experienced in treating pregnant women will assess the client’s posture, alignment, muscle tone, and mobility for regions of restricted movement or mal-alignment which would contribute to swelling, pain, and muscle spasm. S/he will then use various techniques to adjust, manipulate, or realign the joints. This restoration of joint positioning helps to reduce pain and improve movement and function. Some chiropractors will also recommend appropriate stretching and strengthening exercises to help maintain the corrections in alignment. In addition, one study found that women with back pain who were treated with spinal manipulation experienced less back pain during labor. 5
Pros:
- An effective way to correct an alignment problem
- Can sometimes provide immediate relief
- Effective if done in conjunction with the appropriate stretching and stabilization exercises
Cons:
- Can be costly depending on insurance
- Manipulating joints that are already more mobile (as a result of hormonal changes) could result in pain and injury if done incorrectly, so it is important to work with a chiropractor experienced in treating pregnant women
- If done without incorporating exercise, relief may be temporary
Acupuncture
Acupuncture, an ancient form of Chinese medicine, continues to gain popularity as a treatment for back pain in the general population. Recent studies have found that acupuncture helps improve function and reduce the intensity of back pain during pregnancy.6 An acupuncturist will perform a comprehensive exam including an evaluation of the client’s appearance, color, speech, pulses, tongue, and physical condition to determine where the flow of energy is obstructed. The treatment consists of fine needles (generally painless) being inserted into specific points throughout the body to help open the energy channels, thereby restoring balance, reducing pain and muscle spasm, and improving mobility. Acupuncture is safe during pregnancy, with the exception of specific points around the ankle that may stimulate the uterus.
Pros:
- A safe alternative treatment for back pain and restoring good flow of energy
- May also help reduce morning sickness in early pregnancy
Cons:
- Can be costly depending on insurance
- Patients need to be open and receptive to a alternative medicine
- People who fear needles may be intimidated by it
It is important to discuss with your OB/GYN or midwife to determine what type of treatment is best suited for you.
