What it is

Pregnancy-related pelvic girdle pain includes discomfort at the front of the pelvis at the pubic symphysis and at the back near the sacroiliac joints. Hormonal and biomechanical changes, increased load, and prior history influence symptoms. Pain can be sharp with rolling, standing on one leg, stairs, or getting out of a car.

Care focuses on activity planning, pelvic support, and targeted strength training for the hips and deep abdominal muscles. The goal is to maintain steady mobility, sleep, and participation in daily life throughout pregnancy and the postpartum period.

What happens when it occurs

Changing ligament tone and load sharing sensitise pelvic joints. Gait becomes guarded, and tasks on one leg are painful. Simple supports and targeted strength improve comfort. Education on movement strategies protects sleep and daily tasks.

Common causes and risk factors

  • Previous pelvic girdle pain or low back pain
  • Multiple pregnancy or rapid weight gain
  • High occupational or caregiving load
  • Reduced hip and trunk endurance

Who is most affected

Pregnant Australians across trimesters. Symptoms may persist briefly after delivery; early support helps.

Typical symptoms

  • Sharp pain at the pubic bone with rolling or single-leg tasks
  • Pain in the back of the pelvis near one or both sacroiliac joints
  • Clicking or catching at the front of the pelvis in some cases

When to seek care

Immediately for signs of deep vein thrombosis, vaginal bleeding, fever, neurological change, or severe, unremitting pain. Otherwise, seek care when pain limits your ability to walk, sleep, or care for a child.

How we diagnose

History, provocation tests for pubic symphysis and sacroiliac joints, gait and single-leg control assessment, and screening for obstetric red flags. Imaging is rarely required.

Management

  • Education and activity planning with rest breaks during the day
  • Pelvic support belt or taping for short-term relief
  • Hip and gluteal strength, deep abdominal and pelvic floor training
  • Gait retraining and stair strategies, sleep positioning with pillows
  • Postpartum plan to rebuild strength and return to previous activity

Rehabilitation milestones

Pregnancy weeks 0 to 2 from assessment: pain control, support strategies, and gentle strength.

Pregnancy weeks 2 to 8: progressive hip and trunk endurance, gait practice, activity pacing.

Postpartum weeks 0 to 12: graded return to walking, lifting, and caring tasks with pelvic floor and hip strength.

Readiness to progress

  • Walking and rolling in bed without sharp pain
  • Single-leg tasks are controlled and strong
  • Daily tasks completed without next-day flare

Prevention

  • Distribute loads through the day and avoid prolonged single-leg stances
  • Maintain hip and trunk endurance before and during pregnancy as tolerated
  • Use support strategies early when symptoms appear

Australia snapshot

  • Common in perinatal services and physiotherapy across Australia
  • Most improve with support and targeted strength before and after delivery
  • Short-term belts are widely available; early advice improves sleep and mobility

Latest insights

Support early, strengthen steadily, and plan the day to manage load.

Postpartum rebuilding of hip and trunk strength is key to long-term comfort.
