Having an unstable core can be physically exhausting. It could be a mother struggling with a postpartum protrusion or an athlete who notices an unusual protrusion during the heaviest lifts.

Diastasis rectus abdominis is a widespread but misunderstood disorder that impairs the structural integrity of your abdominal wall, resulting in chronic back pain and dysfunction of the pelvic floor. You might be convinced that the old-fashioned fitness practices are aggravating the situation, leaving you frustrated and disconnected from your body. You can consider seeking physical therapy if conventional fitness routines fail.

At Suarez Physical Therapy, our evidence-based rehabilitation goes beyond aesthetics to restore your core's internal stability. Our professional physical therapists will work to ensure that you bridge the gap and regain your strength. Call today for an assessment and start your recovery.

What is Diastasis Recti Abdominis (DRA)?

You might have heard the term "abdominal separation"; however, diastasis recti abdominis (DRA) is a complex physiological disorder characterized by a physical gap. It is a medical condition in which your two rectus abdominis muscles, which run vertically down the front of your abdomen, part ways along the midline. A thick band of connective tissue, called the linea alba, characterizes this midline.

When you experience DRA, the linea alba is thinned and overstretched, losing its ability to support your internal organs and spine with tension. The division may be at, above, or below the belly button, and the gap's width and the connective tissue's tension determine the division's extent.

In contrast to a hernia, where an organ literally protrudes through a hole in the muscle wall, in DRA, the existing tissue is stretched and weakened. You will therefore find that your stomach lacks the "internal corset" feeling it once had. This situation makes your core less effective as a stabilizer, and other muscles have to compensate for the midline's absence, leading to potential issues such as lower back pain and decreased overall stability during physical activities.

Who Is At Risk Of Developing Abdominal Muscular Separation?

  • Postpartum Women. If you are a woman who's had more than one or two pregnancies, your chances are high because your abdominal wall has gone through many cycles of extreme stretching and contraction.
  • Athletes. While the most frequently diagnosed group with DRA is postpartum women, you are also susceptible if you are an athlete and use incorrect bracing methods during heavy compound lifts, particularly if you engage in high-impact sports or activities that place additional strain on the abdominal muscles.
  • Age and Maternal Physical Factors. DRA is more likely in pregnant women over 35 due to collagen loss. Petite women who carry large babies, including twins or triplets, are also at increased risk of mechanical stress on the linea alba, which can lead to conditions such as diastasis recti abdominis (DRA) due to excessive stretching of the abdominal muscles.
  • Risk Factors for Men. If you are a man with a high Body Mass Index (BMI) or who has experienced significant weight changes, the long-term chronic intra-abdominal pressure from visceral fat may lead to stretching of your midline.
  • Surgical History. If you have had abdominal surgery, your fascial layers may be weaker and more likely to separate.
  • Genetic Factors. Certain people have a different collagen composition, making their connective tissues more susceptible to pressure.

Common Causes of Abdominal Muscular Separation

  • Intra-Abdominal Pressure

Excessive and prolonged intra-abdominal pressure is the major cause of DRA. Think of your torso as a pressurized canister. When the pressure inside is too high and there is no outlet, it acts on the weakest part, the linea alba.

This pressure is natural during pregnancy as your developing uterus builds it. Still, hormones such as relaxin and estrogen soften your connective tissues to help deliver the baby. As a result, your muscles will be forced to expand to accommodate the fetus.

  • Everyday Physical Strain

Other than during pregnancy, you can also feel this pressure from chronic straining during bowel movements or from persistent, heavy coughing.

  • Exercise Techniques

When you engage in high-intensity weightlifting and hold your breath when lifting, a technique called the "Valsalva maneuver," without properly engaging your deep core, you are essentially shooting the pressure inside your abdominal wall outward. This is a continuous strain that results in collagen fibers in the linea alba becoming progressively more widely spaced and thinner over time. This condition is a mechanical reaction to overload beyond the tissue's ability to recoil.

  • Weight Fluctuations

Another frequent cause is rapid weight gain, which can shift the rectus muscles laterally due to midsection swelling.

You can start to realize that the key to solving the problem lies in managing pressure and that doing more crunches will never resolve it. Indeed, inappropriate exercise is one of the major reasons for aggravating an already existing separation, as it continues to put pressure on a weakened midline.

Identifying the Signs

DRA may initially manifest only as a visual change, although the clinical manifestations are frequently far more widespread.

Doming Or Coning Effect

The most characteristic symptom you will observe is a doming or coning effect on the midplane of your stomach when you are trying to sit up, lifting a heavy object, or even doing a crunch. This is because your inner pressure is pushing the diluted linea alba outward, as the separated muscles are unable to support it.

Protrusion and Physical Pain

You may also have a permanent "pooch" or protrusion that will not disappear months after giving birth to a child, no matter how much you eat or exercise. In addition to the visual, you should also listen to how your core feels during day-to-day work. Do you experience some flabbiness or disconnection in your midsection? Chronic low back or hip pain may occur when your abdominal muscles no longer support your spine.

Pelvic Floor Complications

Since your core and pelvic floor act as one, Diastasis Recti Abdominis (DRA) is often accompanied by pelvic-floor dysfunction. If you feel a heavy pelvic area or urinate incontinently when you sneeze or jump, your midline separation is affecting your systemic stability.

Poor Posture

You may suffer from poor posture, in which you cannot stand straight without strain.

These symptoms are signals from your body that the bridge of your core is unable to transmit the load efficiently. 

Abdominal Muscle Separation Diagnosis

When you visit the clinic for a diagnosis, you are subjected to a full clinical assessment. Your physician begins by measuring the inter-rectus distance, which is the actual width between your belly muscles. You will be requested to lie down on your back and to make a small directed lift of your head and shoulders.

In this movement, your therapist uses their hands to palpate the space along your midline at the following points:

  • At the belly button

  • Three centimetres above

  • Three centimetres below

The physiotherapist determines the depth and tension of the linea alba. When the fingers of the therapist sink deep into your internal organs, it shows that there is a serious loss of fascial integrity, which is more alarming than a wide and shallow gap. Your therapist also checks the functional response of your muscles to determine whether you can generate tension across that gap when asked to do so.

Also, your physiotherapist tests your breathing patterns and pressure management during functional exercises such as squatting and step-ups. They can also scan your pelvic floor well-being to determine the effects of the separation on your lower core. This technique is a holistic diagnostic method that enables the physical therapist to classify your DRA as mild, moderate, or severe. They also determine whether your core is functional or non-functional at the moment.

This difference is critical, as it determines whether you are prepared to do advanced exercise or you should begin with basic tissue loading.

The “How-To” Physical Therapy Treatment Brief

Physical therapy for DRA uses a tiered rehabilitation model that rebuilds your core from the deepest layers to the surface. This system will ensure that you do not overload the tissue beyond its capacity to hold at any given moment and that the linea alba will slowly regain its density and tension.

Pressure Management And Breathwork

Physical therapists begin by training patients in diaphragmatic breathing to counter the effect of internal pressure pushing against the weakened linea alba. You will learn to control your breath using your rib cage and pelvic floor, rather than pushing it into your abdomen.

This method is critical to avoiding coning, which also increases the distance. You will discover that once you learn to master this breathwork, it is the secret sauce that will eventually enable the rest of your core to heal.

Transverse Abdominis (Tra) Activation

The deepest core layer that therapists pay much attention to is the transverse abdominis, which is the corset around your torso. By strengthening this "internal corset," you create lateral tension that supports the midline.

You will learn specific neuromuscular cues to "draw in" and "cinch" this muscle without using your superficial "six-pack" muscles. This has a tightening effect along the linea alba, and the separated muscle bellies are pulled together without the outward bulge experienced with traditional sit-ups.

Pelvic Floor Coordination

The core and pelvic floor function as a unit, so physiotherapists combine pelvic floor lifts, also known as Kegels, with greater specificity to control the pressure in the torso's soda can. You will be introduced to the process of coordinating your pelvic floor contractions with the contractions of your transverse abdominis. This combination forms a bottom-up support system that stabilizes your spine and reduces the downward and forward pressure that can complicate Diastasis Recti Abdominis (DRA) and cause incontinence.

Functional Progression And Real-Life Application

At this stage, your therapist may require you to progress from floor-based movements to real-world scenarios, such as safely lifting a child, carrying groceries, or returning to weightlifting.

Kinesiology taping or special abdominal bracing can be used as a biofeedback tool during this stage. These external supports are not meant to do the work for you. Instead, they serve as a physical reminder for your brain to keep the muscles engaged. You will also know how to maintain core tension during complex movements so that the muscles do not go lifeless and the midline is not compromised as you resume high-intensity activities.

Exercises to Do and Not to Do During Recovery

Exercise routines for Diastasis Recti Abdominis (DRA), which is a separation of the abdominal muscles, can be complex and challenging. Wrong movements can permanently set back your progress, such as performing traditional crunches or heavy lifting, which can exacerbate the condition. Your therapist should give you a clear roadmap of what to do and what to avoid, ensuring your efforts lead to healing rather than more harm.

Recommended "Safe" Exercises for DRA Recovery

Exercises that allow deep, stable tension without making your belly bulge are what you should focus on. They include:

  • Pelvic Tilts—These enable you to locate your neutral spine and start lightly engaging your core.

  • Heel Slides—These involve testing your core stability: your leg slides against your back, working the deep stabilizers without placing high pressure on the midline.

  • Glute Bridges—These exercises strengthen the posterior chain and will aid in stabilizing the pelvis and take some of the load off the front of your abdomen.

  • Bird-Dogs—These are great in terms of functional coordination because they demand that you have tension along the midline as you move the opposite limbs.

During these exercises, the main aim is to achieve a flat, cinched abdominal profile and ensure there is no coning or doming.

Exercises to Avoid

However, you have some exercises that you should not do until your therapist says so. The most harmful are the following:

  • Traditional Crunches and Sit-ups—These generate a large forward force that pushes your internal organs against the already thin linea alba and may increase the gap.

  • Front Planks—Avoid these if you cannot maintain a flat stomach; if your belly hangs or domes when you are doing a plank, then the weight of your organs is just stretching your connective tissue.

  • Twisting Motions (Russian Twists/Wood Chops)—These exercises produce shearing forces that cut across the midline, which the weakened fascia cannot counter yet.

  • Double-Leg Lifts—These are usually too demanding on a weakened core and will inevitably lead to arching the back and protrusion of the midline.

By following the list of recommended exercises and those to avoid, you will provide your body with the mechanical environment it needs to knit the tissue back together, literally.

Diastasis Recti Surgery

Although the majority of DRA cases respond to specialized physical therapy, there are cases in which conservative care can plateau. Surgery may be an option for severe cases where the separation is over 3 or 4 cm, and the tissue is so thin that it doesn't tighten up after rehabilitation.

When you are also dealing with an actual umbilical or ventral hernia, with organs bulging through the wall, then surgery is no longer an option but a medical necessity. The most commonly performed surgery is an abdominoplasty, also known as a tummy tuck. Your surgeon literally sews the rectus abdominis muscles back together in the midline and removes excess skin. Other contemporary methods use laparoscopic or robotic techniques to insert a mesh or sutures to strengthen the linea alba with minimal scarring.

Surgery is not the quick fix for a healthy core. Physical therapy is also necessary before and after surgery, even when you choose the surgical route. “Pre-hab” allows you to train the muscles around and learn to manage pressure, which will result in a much more successful surgery. After surgery, physical therapy is even more urgent; the surgeon can put the muscles back, but can't make them work.

You still have to go through neuromuscular re-education to train your brain on how to utilize those new muscles that are in place. In the absence of a tiered rehabilitation model, most surgical patients discover that their separation ultimately comes back since they never dealt with the pressure-management issues that had led to the stretching in the first place.

Your physical therapist should collaborate with surgeons to ensure that, if you need a repair, it is all-inclusive and your outcomes are long-term.
