Clinicians who desire to dig deeper into the multifaceted role of the diaphragm in both respiration and posture as well as learn more about evidenced-based treatment options to improve outcomes in these areas.


  1. Discuss the role of the diaphragm in respiration at rest and during activity
  2. Discuss the role of the diaphragm as it contributes to postural support
  3. Explain how pressures (thoracic & abdominal) are involved.
  4. Connect the application of Respiratory Muscle Training targeting diaphragm strength with the various functional outcomes that depend on adequate respiratory support as well as postural stability.

Mary Massery, PT, DPT, DSc
Owner, Clinician and Clinical Educator

Dr. Massery received her BS (Bachelor of Science) in Physical Therapy from Northwestern University in 1977, her DPT (Doctor of Physical Therapy) from the University of the Pacific in 2004, and her DSc (Doctor of Science) from Rocky Mountain University in 2011. She has been invited to give over 1000 professional presentations in all 50 US states and in 18 countries worldwide on topics linking motor behaviors to breathing and postural mechanics. Mary’s research pioneered the concept of managing trunk pressures as a new way to visualize core stabilization.Dr. Massery received the American Physical Therapy Association’s highest clinical award, The Florence Kendall Practice Award, for “outstanding and enduring contributions to the practice of physical therapy.” She has been named Outstanding Alumnus of the Year by each of her 3 universities, and she received Northwestern University’s Alumnae Research Achievement Award. Mary continues to maintain a private practice in Chicago, specializing in breathing and postural dysfunction.
