What is Pelvic Dysfunction

There are two conditions under the general term of Pelvic Dysfunction: Symphysis Pubis Dysfunction and Diastasis Symphysis Pubis. The symptoms are the same, so what is the difference?

1. Symphysis Pubis Dysfunction (SPD)

SPD occurs when the joint at the front of the pelvis (called the symphysis pubis) becomes unstable. This joint, along with the two joints at the back of the pelvis (the sacroiliac joints), helps keep your pelvis steady during movement.

When the ligaments holding these joints become too loose, excessive strain is placed on the pelvis — causing pain, instability, and difficulty moving.

“Normal” vs. Abnormal Joint Gaps

• Normal gap (non-pregnant): 4–5mm

• Normal during pregnancy: Up to 9mm

• This extra space is due to relaxed ligaments and usually returns to normal a few months after birth.

2. Diastasis Symphysis Pubis (DSP)

DSP is a more severe form of SPD where the gap at the pubic joint is 10mm or more, often with misalignment of the bones. This is confirmed by MRI, ultrasound, or x-ray (post-partum) and may require longer recovery time.

Diastasis Symphysis Pubis

DSP means an abnormally wide gap is present between the two pubic bones at the symphysis pubis, diagnosed conclusively by investigation such as x-ray (post-partum), ultrasound or an MRI scan (magnetic resonance imaging).

An abnormal gap is considered to be 10mm or more, sometimes with the two bones being slightly out of alignment. This abnormal gap remains evident after the time that the joint should have regained the normal non-pregnant width.

What Causes SPD?

SPD is often caused by a combination of pregnancy hormones and biomechanical strain. Some women may be more prone to it, especially if they:

• Have had more than one pregnancy

• Are carrying a large baby

• Had previous pelvic injuries

• Have a history of lower back or sacroiliac pain

• Have flexible joints

Common Symptoms of SPD

Each woman experiences SPD differently, and pain levels don’t always match the severity of the joint separation. Symptoms may include:

• Pain over the pubic bone (burning, stabbing, or bruising)

• Lower back or hip pain

• Pain that spreads to the inner thigh or groin

• Clicking or grinding in the pelvic area

• Waddling or shuffling when walking

• Difficulty moving your legs apart (e.g. getting out of a car)

• Trouble with daily tasks like:

  • Rolling over in bed

  • Climbing stairs

  • Getting dressed

  • Bending, lifting, or walking for long periods

  • Getting into or out of a bath or car

When Does SPD Pain Start?

SPD pain can start as early as 12 weeks, due to the rise in relaxin levels. It may build gradually throughout pregnancy or come on suddenly — for example, after a fall or awkward movement.

Self-Help Tips for SPD Relief

Here are some simple ways to manage SPD and reduce your pain:

Movement & Posture

• Keep your legs together when getting in/out of bed or a car

• Take small steps and avoid wide leg movements

• Avoid crossing your legs or standing on one leg

• Use a pillow between your knees when sleeping

Around the House

• Sit down for activities like getting dressed or preparing food

• Avoid heavy lifting, vacuuming, or twisting

• Use satin sheets to help turn over in bed more easily

• Use a plastic bag on your car seat to help you swivel in and out

Activity & Rest

• Avoid high-impact exercises (especially breaststroke swimming)

• Take regular breaks and avoid standing for too long

• Consider aquanatal classes (with caution)

• Use a pelvic support belt or crutches if needed

Plan Ahead

• Think through each task before you do it

• Organize your day to reduce unnecessary movement

• Accept help when it’s offered

Most importantly: listen to your body. If it hurts — don’t do it.

Chiropractic Treatment for SPD

Chiropractic care offers a safe and natural approach to managing SPD. Your chiropractor will take a detailed history and perform an exam to diagnose your condition.

Treatment may include:

• Gentle realignment of pelvic joints (sacroiliac and pubic symphysis)

• Soft tissue and ligament work

• Gentle release techniques (including diaphragm and pelvic floor)

• Use of blocks, belts, and non-force methods like the Activator

• Webster Technique (often used for breech babies)

• Ice therapy

• Ultrasound or low-level laser therapy

• Tailored exercises and lifestyle advice

Why Early Chiropractic Care Matters

Starting treatment early can prevent SPD from becoming severe or chronic. Most women respond well to chiropractic care both during and after pregnancy — especially when pelvic misalignment is the root cause.

Chiropractic care aims to correct the source of the problem, not just mask the symptoms.

If you’re struggling with pelvic pain during or after pregnancy, chiropractic care may help restore your mobility, comfort, and confidence — naturally.
