Diastasis Recti Abdominis (DRA)

A strong, functional core is important for everything you do—let us help you rebuild it with confidence.

What is Diastasis Recti Abdominis (DRA)?

Diastasis Rectus Abdominis (DRA) is the separation of the two rectus abdominis muscles—the “six-pack” muscles—along the linea alba (the connective tissue that runs down the center of the abdomen). This condition commonly develops during pregnancy due to hormonal changes and the stretching force of a growing uterus, but it can also occur in men and non-pregnant women, especially in cases of obesity or repetitive abdominal strain.

The abdominal wall is designed to do far more than just look flat—it transfers force between the upper and lower body, supports breathing, stabilizes the trunk, and protects the spine and pelvis. When DRA is present, this natural support system is compromised, sometimes leading to symptoms such as abdominal pain, low back pain, pelvic instability, or difficulty performing everyday tasks. Some people also notice a visible bulge or “doming” in the midline when they sit up or strain.

Research has helped shift the way we understand and treat DRA:

  • Strengthening matters. A 2017 study (Kamel & Yousif) demonstrated that targeted abdominal strengthening combined with neuromuscular re-education is more effective in reducing DRA than exercise alone. This highlights the importance of guided, progressive rehabilitation rather than random core workouts.
  • It’s not just about “closing the gap.” A 2016 study by Diane Lee and Paul Hodges showed that muscle recruitment patterns are more important than the actual width of the gap. For example, engaging the transverse abdominis (deep core muscle) during a small crunch can create optimal tension across the linea alba, allowing the abdominals to function effectively—even if the separation is still present.
  • Function over finger-widths. A common misconception is that the gap must close to less than two fingers’ width to restore function. In reality, many people can have a three-finger gap and still demonstrate a strong, functional core without doming, bulging, or pelvic floor symptoms.

Common Symptoms

How Does It Feel?

  • A visible bulge or doming down the center of the abdomen
  • Abdominal pain or discomfort
  • Low back pain
  • Sensation of weakness or instability in the core
  • Difficulty lifting, carrying, or performing daily tasks
  • Pelvic floor issues, including prolapse or urinary leakage

What Causes It?

The primary cause of DRA is excessive, repetitive strain on the linea alba—the connective tissue that holds the two halves of the rectus abdominis together.

Contributing factors include:

  • Pregnancy and the effect of relaxin and progesterone on connective tissue
  • The natural stretching of the abdominal wall to accommodate a growing baby
  • Obesity, which increases abdominal pressure
  • Poor exercise technique or repeated high-pressure abdominal movements
  • Genetics and connective tissue integrity

How We Identify the Root Cause

At Sarton Physical Therapy, our pelvic floor and core specialists provide a comprehensive evaluation that includes:

  • A detailed history of pregnancy, delivery, abdominal strain, or weight changes
  • Assessment of your abdominal wall integrity and ability to generate tension across the linea alba
  • Screening for related conditions such as pelvic organ prolapse or low back dysfunction
  • Evaluation of posture, breathing, and movement patterns that may increase intra-abdominal pressure
  • Collaboration with your referring physician or other providers as needed

This whole-body approach allows us to determine not just if you have DRA, but how it is affecting your function—and most importantly, how to restore strength and stability safely.

How We Help 
You Heal

At Sarton Physical Therapy, our goal is not just to “close the gap,” but to restore full strength, function, and confidence in your core. Every patient is different, so we design a plan that’s tailored to your body, your history, and your goals.

We focus on retraining your deep abdominal system—especially the transverse abdominis—in coordination with the pelvic floor, diaphragm, and spinal stabilizers. This whole-core approach helps create tension across the linea alba, improves stability, and protects against issues such as back pain or prolapse.

With consistent guidance, you’ll learn how to move, lift, and exercise with confidence again—whether that’s caring for your baby, returning to sport, or simply feeling strong in your own body.

  • Manual therapy
  • Neuromuscular re-education
  • Progressive core strengthening
  • Education on safe movement strategies for daily life
  • Training to recognize and correct harmful pressure habits (like breath-holding or straining)
