Abdominal Separation & 

Rectus Diastasis

What is it?

Rectus Diastasis also know as ‘abdominal separation’ is a condition that occurs predominantly during pregnancy, whereby the abdominal muscles separate away from each other at the midline (linea alba).

Two thirds of pregnant women will have it.

Mechanism of Injury

Common Management Techniques

1.     Specific Gentle Core Exercises – these need to be prescribed by your physiotherapist depending on where the separation is and the level of strength in your core. This will help facilitate the coming back together of the linea alba.

2.     Education/Advice – there are certain activities and positions to avoid with rectus diastasis, and correct ways to reduce the risk of increasing the separation.

3.     SRC Pants – the only graded compression garment endorsed by the Physiotherapy Association, with backed research to help facilitate the closing of the separation



Fortunately, the majority of people who experience Abdominal Separation in pregnancy experience a significant improvement in symptoms in the weeks after birth with most people back to full function and normal diastasis after 6 weeks post birth.
