Five years ago, the COVID-19 pandemic devastated the world on a scale not seen in nearly a century. Hospital systems became overwhelmed as the number of patients requiring hospitalization and mechanical ventilation surged. In the years since, the Centers for Disease Control and Prevention (CDC) has defined terms such as "Long COVID" and "Post-COVID Condition" to describe individuals who continue to experience symptoms well after recovering from the acute phase of the virus. As it relates to our work, a key question emerges: What are the short- and long-term effects of COVID-19 on the diaphragm?
A study by Spiesshoefer et al. (1) examined patients hospitalized with COVID-19 and assessed them approximately two years after discharge. They found that persistent diaphragm muscle weakness and exertional dyspnea remained prevalent. In their study, participants were divided into two groups—one group received six weeks of inspiratory muscle training (IMT), while the control group received a sham intervention. The IMT group demonstrated statistically significant improvements in exertional dyspnea and diaphragm function, although there was no notable change in diaphragm thickness. Importantly, these improvements persisted after the six-week intervention concluded.
Similarly, Ahmad et al. (2) compared diaphragm release techniques with conventional breathing exercises in female patients recovering from COVID-19. After just nine sessions over a three-week period, the diaphragm release group showed greater improvements in chest wall expansion, oxygen saturation, and performance on the six-minute walk test compared to the breathing exercise group.
Together, these studies highlight the importance of incorporating both breathing exercises and manual therapy techniques to optimize breathing mechanics, support chest wall mobility, enhance oxygen saturation, and reduce exertional dyspnea during walking and other functional activities.
In the Breathing and the Diaphragm course taught by Aparna Rajagopal and Leeann Taptich, a systematic and holistic approach to evaluation and treatment will be discussed, covering not only recovery from COVID-19 but also pelvic floor dysfunction, gastrointestinal disorders, and chronic low back pain. To deepen your understanding of the diaphragm’s crucial role in health and rehabilitation, register for the May 31, 2025 course through Herman & Wallace.

Leeann Taptich, PT, DPT (she/her) has been a physical therapist since 2006. She graduated with a BS in Kinesiology from Michigan State University and a Doctorate of Physical Therapy from the University of St Augustine. In 2009, she earned her Manual Therapy from the University is St Augustine and her board certification as a Sports Certified Specialist in 2018.
Leeann leads the Sports Physical Therapy team at Henry Ford Macomb Hospital in Michigan, 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. With her combination of credentials and her exposure to pelvic health,h she is able to use a very eclectic but complete approach in her treatment of orthopedic and sports patients. With the hospital system, she is involved with the community promoting health and wellness at local running competitions and events.
Leeann is passionate about educating and teaching and has assisted in teaching multiple courses at the local State a university PT department. She is co-chair of the continuing education committee at her hospital where she writes and develops courses. She is a co-author of the Breathing and Diaphragm class at Herman & Wallace.
Leeann lives in the metro Detroit area with her husband and 2 children. She enjoys hiking, traveling, and watching football.
This article was submitted by Aparna Rajagopal and LeeAnn Taptich. Both practitioners are based out of the Henry Ford Macomb Hospital in Michigan where Aparna Rajagopal, PT, MHS is the lead therapist of their pelvic dysfunction program, and Leeann Taptich DPT, SCS, MTC, CSCS leads the Sports Physical Therapy team. Michigan. They work very closely together at the hospital which gives them a very unique perspective of their patients. Aparna and LeeAnn instruct the Breathing and the Diaphragm course. This remote course explores how the diaphragm, breathing, and the abdominals can affect core and postural stability through intra-abdominal pressure changes.
COVID-19 has been a part of our vocabulary for almost 2 years now and has changed the world we live in. COVID-19 is a virus that affects the cardiovascular, digestive, urinary, and respiratory systems. We still do not have adequate evidence to guide our treatment of COVID -19 patients in their sometimes prolonged recovery phase. Research continues to be made available about the short and long-term effects of the virus on our bodies.
An example of a post-COVID-19 patient was a female with complaints of difficulty taking in a deep breath. She also reported that the physical act of breathing felt like a lot of work/effort. She had undergone all sorts of respiratory and cardiac testing and had been cleared from a medical standpoint. Upon talking to the patient, it was discovered that she wasn't complaining of shortness of breath/dyspnea.
Instead, this patient was complaining about having to expend a lot of energy to perform the mechanical action of breathing. She reported that this had started after she had experienced moderate COVID - 19 symptoms for about a month. The patient did extremely well with a plan of treatment aimed at improving mobility in the soft tissues and joints of the thorax while working on establishing a breathing pattern with a focus on improved overall expansion. An incidental benefit of her treatment was a dramatic reduction in her symptoms of urinary urgency which she had developed during her COVID-19 recovery stage.
Recently, a clinical commentary in the Journal of Women’s Health Physical Therapy talked about the possibilities of pelvic floor dysfunction developing on account of COVID-19 (1). Since COVID 19 affects the respiratory system, we can postulate that something involving the respiratory system will possibly have an effect on the pelvic floor due to the unique relationship shared between the pelvic floor and the diaphragm.
Recovering COVID 19 patients may have changes in their musculoskeletal system. These changes may include increased accessory muscle use, decreased chest wall mobility (including the associated joints and muscles), and altered breathing mechanics due to both the disease process and possibly the immobility of bed rest.
The upcoming Breathing and the Diaphragm course helps practitioners understand the connection of dysfunction pertaining to respiration and how it can affect the pelvic floor. In this course, Aparna Rajagopal and LeeAnn Taptich will instruct you to look at the body as a whole while assessing and treating for mobility deficits, motor control deficits in terms of breathing dysfunction presented by these patients.
