From the Guidelines

Back pain during pregnancy should be managed with a combination of proper posture, gentle exercise, and supportive devices, as these methods have been shown to reduce pain and improve quality of life. According to the study by 1, regular moderate-intensity prenatal physical activity throughout pregnancy can help reduce the risk of complications such as low birth weight, pre-eclampsia, or preterm birth, and can also help alleviate back pain.

Some key strategies for managing back pain during pregnancy include:

  • Maintaining proper posture and body mechanics, such as standing straight and avoiding prolonged standing
  • Engaging in regular gentle exercise, such as walking, swimming, or prenatal yoga, to strengthen back muscles and improve flexibility
  • Using supportive devices, such as pregnancy support belts, maternity pillows, and proper footwear, to help maintain alignment
  • Applying heat or cold therapy to the painful area for 15-20 minutes several times daily
  • Considering physical therapy, prenatal massage, or acupuncture as additional options for pain management

It's also important to note that medication, such as acetaminophen (Tylenol), can be used to manage back pain during pregnancy, but it's essential to consult with a healthcare provider first and follow their recommended dosage, as high doses can have adverse effects on the fetus 1. Additionally, NSAIDs like ibuprofen should be avoided, especially in the third trimester, due to the potential risks to the fetus.

The study by 1 highlights the importance of addressing back pain during pregnancy, as it can have a significant impact on a woman's quality of life and overall well-being. By prioritizing proper posture, gentle exercise, and supportive devices, women can reduce their risk of back pain and improve their overall health during pregnancy.

In terms of specific exercises, the study by 1 suggests that regular moderate-intensity prenatal physical activity can help reduce the risk of complications and alleviate back pain. Some examples of gentle exercises that may be beneficial for back pain during pregnancy include:

  • Prenatal yoga
  • Swimming
  • Walking
  • Pelvic tilts
  • Kegel exercises

It's essential to consult with a healthcare provider before starting any new exercise routine during pregnancy, especially if you have any underlying medical conditions or concerns. They can help you develop a personalized exercise plan that meets your needs and ensures a healthy pregnancy.

From the Research

Prevalence of Back Pain in Pregnancy

  • Approximately 50% of all pregnant women experience back pain during pregnancy 2
  • More than two-thirds of pregnant women experience low-back pain (LBP) and almost one-fifth experience pelvic pain 3

Causes and Risk Factors

  • The causes and risk factors associated with back pain encountered during pregnancy continue to be evaluated 2
  • Recognizing characteristics of the frequently encountered back pain of pregnancy as well as uncommon sources of back pain during pregnancy is essential in establishing an accurate diagnosis and initiating prompt and effective management 2

Treatment Options

  • Chiropractic care is a commonly used treatment modality for musculoskeletal pain in pregnancy, including low back pain, pelvic pain, and other neuromuscular complaints 4
  • Exercise has been shown to significantly reduce pain and disability from LBP 3
  • Acupuncture has been found to significantly reduce evening pelvic pain or lumbo-pelvic pain more than usual care alone 3
  • Yoga has been shown to benefit women who suffer from anxiety, depression, stress, low back pain, and sleep disturbances during pregnancy 5

Effectiveness of Interventions

  • Moderate-quality evidence suggests that acupuncture or exercise, tailored to the stage of pregnancy, significantly reduces evening pelvic pain or lumbo-pelvic pain more than usual care alone 3
  • Low-quality evidence suggests that physiotherapy, osteopathic manipulation, acupuncture, a multi-modal intervention, or the addition of a rigid pelvic belt to exercise seems to relieve pelvic or back pain more than usual care alone 3
  • Inconclusive, favorable evidence for chiropractic care, exercise, and support devices for pregnancy-related low back pain (LBP) 6
