Abdominal bloating and distension are common symptoms reported in pelvic health practice. While many individuals experience occasional bloating that resolves without intervention, persistent or long-standing distension can significantly impact quality of life. Patients often report discomfort, sleep disruption, dietary restrictions, and frustration when symptoms persist without clear answers.

One condition associated with these symptoms is abdomino-phrenic dyssynergia, a disorder involving a paradoxical relationship between the diaphragm and abdominal wall.

Under normal conditions, when intraluminal gas increases in the gastrointestinal tract, the body responds with a coordinated pattern:

• the diaphragm relaxes, and
• the abdominal wall contracts

This response helps maintain abdominal shape and pressure regulation.

However, in abdomino-phrenic dyssynergia, the opposite pattern occurs. The diaphragm contracts downward while the abdominal musculature relaxes, leading to visible abdominal distension and discomfort. Dysfunction of the pelvic floor is also frequently associated with this condition, reinforcing the importance of a comprehensive evaluation of the entire pressure management system.

Traditional management strategies include biofeedback therapy and breathing retraining, both aimed at restoring appropriate neuromuscular coordination.

A Clinical Case Example

In our clinic, we are seeing an increasing number of referrals for patients diagnosed with abdomino-phrenic dyssynergia. One recent patient illustrates how breathing mechanics and musculoskeletal restrictions can contribute to these symptoms.

The patient was a 72-year-old female with a long-standing history of abdominal bloating and distension.

She reported:

• Bloating and abdominal distension throughout the day, worsening toward evening
• Limiting evening food intake due to abdominal discomfort and “tightness”
• Pain rated 3–5/10 in the morning, increasing to 8/10 by late evening
• Difficulty sleeping due to the abdomen feeling “hard and tight” at bedtime

Examination Findings

Physical examination revealed several contributing factors:

• Significant tightness in the posterior chain and erector spinae in the thoracic and lumbar regions
• Reduced thoracic rotation and mobility
• Connective tissue restrictions in the upper abdominal quadrants, especially the epigastric region and inferior rib cage
• Decreased lower rib cage mobility
• Difficulty producing a prolonged or forceful exhale
• Reduced ability to relax the pelvic floor following contraction

These findings highlighted the interaction between breathing mechanics, rib cage mobility, myofascial restrictions, and pelvic floor coordination.

Treatment Approach

Treatment included a multi-system approach addressing breathing, mobility, and neuromuscular coordination.

Interventions included:

• Biofeedback therapy
• Visceral mobilization techniques
• Thoracic spine and rib joint mobilizations
• Soft tissue techniques, including gentle diaphragm release
• Breathing retraining
• Techniques focused on pelvic floor relaxation

The patient completed nine treatment sessions, combined with a structured home maintenance program that she followed consistently.

Outcomes

By the end of treatment, the patient reported:

• 70% overall improvement in symptoms
• Ability to eat evening meals without discomfort
• Restful sleep through the night without abdominal tightness

This case highlights how restoring efficient breathing mechanics and rib cage mobility can significantly influence abdominal pressure regulation, pelvic floor function, and patient comfort.

Why Breathing Matters for Pelvic and Orthopedic Therapists

Breathing is far more than a respiratory function. The diaphragm plays a central role in:

• pressure regulation
• core stability
• pelvic floor coordination
• movement efficiency

Understanding how breathing integrates with the musculoskeletal system can significantly expand a clinician’s ability to address persistent symptoms that may otherwise be overlooked.

In the course Breathing and the Diaphragm: Pelvic and Orthopedic Therapists, we explore these relationships in depth and provide clinicians with practical tools to assess and treat dysfunctional breathing patterns.

Participants will learn how to:

• Explain normal diaphragmatic breathing and the role of the internal and external oblique musculature
• Assess and treat dysfunctional breathing patterns including chest, abdominal, and paradoxical breathing
• Understand the role of intra-abdominal pressure (IAP) in spinal stability
• Apply the concept of regional interdependence in patients with pelvic or back pain
• Recognize how postural patterns influence diaphragm and pelvic floor function
• Identify myofascial contributors to dysfunctional breathing and apply appropriate treatment techniques
• Perform rib and thoracic spine mobilizations to improve respiratory mechanics
• Develop exercise progressions for breathing retraining in clinic and home programs
• Integrate diaphragmatic breathing strategies into athletic rehabilitation

Understanding the relationship between breathing mechanics, mobility, and pelvic floor function allows clinicians to address dysfunction from a more integrated perspective and can lead to meaningful improvements in patient outcomes.

Aparna Rajagopal, PT, MHS, WCS, PRPC, Capp-OB Certified is the lead therapist at Henry Ford Macomb Hospital's pelvic dysfunction program, where she treats pelvic rehab patients and consults with the sports therapy team. Her interest in treating peripartum patients and athletes allowed her to recognize the role that breathing plays in pelvic dysfunction.

Leeann Taptich DPT, SCS, MTC, CSCS leads the Sports Physical Therapy team at Henry Ford Macomb Hospital where she mentors a team of therapists. She also works very closely with the pelvic team at the hospital which gives her a very unique perspective of the athlete.

Aparna and Leeann co-authored the course, Breathing and the Diaphragm: Pelvic and Orthopedic Therapists, which helps clinicians understand breathing mechanics and their relationship to the pelvic floor.

Description: This remote course is an integrated approach where participants will learn how the diaphragm, breathing, and the abdominals can affect core and postural stability through intra-abdominal pressure changes while looking at structures from the glottis and the cervical region to the pelvic floor.

This course includes assessment and treatment of the barriers by addressing thoracic spine articulation and rib cage abnormalities in the fascial system of muscles related to breathing and the diaphragm. Instructed techniques are applicable to patients who present with Diastasis Rectus Abdominis, pelvic pain, incontinence, and prolapse, as well as cervical, thoracic, scapular, and lumbar pain.

Proper breathing is discussed and taught in many ways and forms. All of this is a step in the right direction, but what if the person physically can not lengthen tissues to expand certain key structures that are essential to the breathing mechanism? In the remote course, Breathing and the Diaphragm, Aparna Rajagopal and Leeann Taptich teach different methods to identify breathing patterns, dysfunctional breathers, and how to determine motor control issues from mobility or strength issues.

Breath is utilized widely in the exercise world. Pilates uses breath for core stability. Yoga utilizes breath to help connect the body. Strength and conditioning coaches and personal trainers emphasize breath to provide power to lift. Breathing mechanics, aka proper breathing, is also core to any type of abdominal exercise.

Respiratory muscles are directly involved in these core abdominal strengthening, stability, and stretching exercises (1). Research led by DePalo, way back in 1985, concluded that the diaphragm is actively recruited during resistance exercises such as sit-ups (2). Inefficient breathing can lead to muscular imbalances, and motor control changes that can affect motor quality. Therapists are taught at length about tissue and joint mobility versus motor control or strength issues. These same principles can be applied to assess and treat the diaphragm, breathing, and abdominals.

In regards to working with patients, Aparna shares, "Different cues work with different patients. While verbal and tactile cues to correct patterns can work with some of our patients, they do not necessarily work in all of our patients. We need different ways to correct patterns in patients that have a tissue or joint mobility issue. Such issues can cause restriction and force the patient to breathe in a specific way."

Aparna and Leeann deep dive into mobility and learn to assess and treat joint restrictions of the ribs and the thoracic spine during their remote course Breathing and the Diaphragm scheduled for October 23-24, 2021. These mobility techniques combined with specific motor control and strengthening exercises can improve myofascial restrictions that restrict breathing.

Breathing and the Diaphragm will help build a foundation to improve your patients' functional activities. No matter if it is coughing, having a bowel movement, performing wall ball in CrossFit, or hitting a tennis ball!
