Dr Joshua Boucher | The Fascial Distortion Model: A Clinical Tool for Musculoskeletal Pain

Jul 13, 2023 | Health and Medicine

Musculoskeletal pain can be extremely debilitating and although common, it can also be difficult to treat. Dr Joshua Boucher, an osteopathic physician based at Southeast Alaska Regional Health Consortium, is working to show how the Fascial Distortion Model (FDM) can alleviate the pain and decreased function associated with musculoskeletal injuries. His encouraging findings are establishing the FDM as a useful clinical tool, and more research is already underway.

Musculoskeletal Pain and Fascia

Musculoskeletal pain can affect bones, joints, ligaments, tendons, muscles, and fascia. The causes vary from injury to long-term health conditions. Affected individuals report often persistent pain and limitations to their mobility and dexterity, impacting their ability to live a full and productive life. The World Health Organization estimates that globally, approximately 1.71 billion people suffer from musculoskeletal conditions of some form, meaning they represent a leading cause of disability.

Common musculoskeletal injuries include bone fractures, sprained ankles, and tendinopathies. The Fascial Distortion Model (FDM) by the American physician, Dr Stephen Typaldos, proposes that musculoskeletal injuries are the result of damage to fascia – the connective tissue that lies beneath the skin. This thin, stringy tissue is mostly made of collagen and wraps around each and every organ, blood vessel, bone, nerve fiber, and muscle in our bodies. When healthy, fascia provides us with the support, stability, and flexibility we need to move. But it can go wrong…

When Fascia is Damaged

The FDM describes six different fascial distortions (or diagnoses) that can occur when fascia is somehow damaged. The most common is a triggerband, in which the fascia becomes wrinkled. Herniated triggerpoint occurs when soft tissue pushes through the layers of fascia. Continuum distortion refers to the alteration of fascia between two different tissue types. In a folding distortion, the fascia has become contorted as the result of pulling or pressure such as twisting. Cylinder distortion is the term used for tangled coiling of the fascia, and finally, tectonic fixation occurs when the fascia cannot glide in its plane. Specific diagnoses are made based on how the patient describes and demonstrates their pain.

Dr Joshua Boucher, previously of the Dwight D. Eisenhower Army Medical Center, William Beaumont Army Medical Center, and now of the Southeast Alaska Regional Health Consortium, became familiar with the FDM during his medical training and quickly saw its untapped potential. He completed full training at the FDM Academy and became internationally certified through the American Fascial Distortion Model Association and now works to advance the field through research and education.

A Case Study – with Impressive Findings

In 2018, Dr Boucher published one of his early applications of the FDM in the Journal of Osteopathic Medicine in collaboration with Dr Jose Figueroa, of the Des Moines University College of Osteopathic Medicine in Iowa. This was a single case study of a patient with ‘frozen shoulder’ – so called because of the stiffness and pain that limits the individual’s range of movement. The symptoms can last for months and even years and while recovery may sometimes occur without treatment, this process is likely to be prolonged and the full range of motion may not ever be fully restored. Conventional treatment approaches include painkillers, anti-inflammatory drugs, and physiotherapy.

On encountering a 28-year-old male with frozen shoulder that had not responded to conventional self-treatment at home with medication and exercise, Dr Boucher recognized that the FDM might be an effective alternative. The pain had remained constant since the injury 18 months before, and the limitation to movement typical of the condition had progressively worsened over time, limiting the patient’s ability to conduct day-to-day tasks and even play with his children.

Osteopathic examination confirmed that the shoulder pain resulted from a hyperextension injury, in which the joint had been forced to move beyond its normal range of motion. Dr Boucher identified three fascial distortions of the shoulder: Herniated triggerpoint, triggerband, and folding distortion. Initial treatment of firm pressure using the FDM resulted in immediate benefits, with the patient reporting improved movement and reductions in pain on completion of this first intervention. He attended for a follow-up appointment two weeks later, during which Dr Boucher applied the FDM intervention again, this time resulting in the full restoration of movement and complete removal of pain. Three months later, the patient happily confirmed his complete recovery and the resumption of daily activities.

While the application of the FDM can result in temporary discomfort for both the patient and the practitioner during the manual procedure, the outcomes of this case study were certainly impressive, and confirmed the potential of the FDM as a noninvasive and alternative approach to managing musculoskeletal injuries.

Delving Deeper into Why

Encouraged by these findings and his work as a military physician in which he repeatedly saw the effectiveness of the FDM, Dr Boucher wanted to understand more about how and why the FDM could be so effective.

One condition that he frequently treated in his work was plantar heel pain, which occurs on the bottom of the foot (also known as plantar fasciitis). He discovered that it is possible to measure the thickness of the plantar fascia to track objective changes in the condition over time. Seeing that this could provide direct evidence of improvement as a result of treatment for plantar heel pain, Dr Boucher knew he could now delve deeper into the effects of the FDM.

During the intern year of his Family Medicine residency, Dr Boucher started the long and difficult process of requesting institutional review board approval to conduct this research, supported by his mentor, Dr Scott Mooney. Never in the USA had the FDM been studied on a large scale before and thus, safety data were limited – which made it difficult. But after nearly a year, the required approval was received, and the researchers started the study.

Objective Evidence of Improvement

The participants were full-time military personnel who reported heel pain for at least 30 days and also had a clinical diagnosis of plantar heel pain. Dr Boucher used the FDM diagnostic and treatment strategy to identify fascial distortions according to patient-reported pain patterns and examination. He applied the therapy at this point and again one week later with a total of 28 participants.

Once again, the results were impressive, showing significant and sustained improvement on a range of validated measures of pain and physical function. But most critically, the thickness of the plantar fascia was reduced, as assessed by ultrasound at the beginning of the study and follow-up at 16 weeks. The ultrasound was conducted by a radiologist ‘blinded’ to each participant’s status in the study, meaning the interpretation of the scans was free from any potential bias.

Although small, this study represents an important milestone for the FDM. Building on clinical observation and subjective reports of benefits from participants, this study confirmed that the benefits could be directly and objectively observed.

A Solid Foundation for Further Research and Progress

Dr Boucher isn’t stopping yet and he believes there is much more to learn about the FDM. He is currently working on two survey-based studies and notes that we still have little data on the side effects, safety, and effects of the FDM in other musculoskeletal conditions. These are important gaps to fill in the near future.

Nonetheless, the findings from Dr Boucher suggest that compared to other interventions, the FDM is relatively inexpensive, least invasive, and can lead to the fastest onset of recovery for musculoskeletal pain. Having provided a solid foundation on which to build, he is committed to advancing and pioneering FDM research further.

Having personally observed the impact that the FDM has had on his patients, Dr Boucher is working on becoming a member of the FDM Academy to help teach the FDM across the USA. You can learn more about the courses at https://afdma.com/ and https://www.thefdmacademy.com/

Professor Kim McDonough – Professor Pavel Trofimovich | New Insights into Non-verbal Aspects of Second Language Learning

Although most people study a second language in school, this education alone is seldom sufficient to achieve the level of proficiency needed to live in a foreign country. But in a world where global migration is increasingly common, learning a second language has become essential for millions of people. Professors Kim McDonough and Pavel Trofimovich at Concordia University, Canada, study language learning, and in doing so, are helping those trying to become competent in the use of a second language.

Dr Jon Neill | The Impact of Trade Deficits in America

Former President Donald Trump promised to bring jobs back to the U.S., arguing that the trade deficit was responsible for slow economic growth and costing the economy jobs. While the Trump administration popularised the issue, historically, the broad impact of trade deficits has been contentious. Dr Jon Neill is a Professor of Economics at Western Michigan University. His computational modelling has shown that U.S. residents would experience a slight loss if consumer goods currently being imported from countries like China, were produced domestically instead. His calculations question whether the net benefit from trade with low-wage countries is warranted, given the distributional impact of that trade.

Dr Kyla Zatti | Aquaculture Feed: Progressing the Use of Algal Oils in Salmon

Salmon and other seafood represent a large and important food source. Traditionally, salmon diets consisted mainly of fish, although over the last decade, they have become more vegetable based. However, salmon require essential lipids, which are hard to find except in fish oil. Dr Kyla Zatti and a group of scientists at BioMar have been working to effectively bypass fish oil in their aquafeed by going to the original source of the lipids while maintaining the welfare, growth, and quality of the fish produced.

Professor David E. Sugden | James Croll, Ice Ages and Ice Sheets

The phrase ‘standing on the shoulders of giants’ is often attributed to Sir Isaac Newton, meaning that scientific progress is only possible due to the contributions of the scientists who came before. However, many of these giants’ contributions are often forgotten or ignored in favour of their more famous peers. In the field of glaciology, Professor David E. Sugden from the University of Edinburgh is aiming to draw attention to one of the overlooked giants of his field – James Croll, whose work on Ice Age Theory is still relevant today.
