Myopraktikk (NO): A Narrative Review and Conceptual Hypothesis on Intrafasciomembranal Fluid Pressure, Biotensegrity, and Immediate Remote Myofascial Responses.
Hopen, Stig Runar, Mjøen, Tor Arne · Cureus · 2025 · DOI
Quick Summary
This article proposes a new theory about muscle pain and stiffness called Myopraktikk, which focuses on fluid pressure building up in the spaces around muscles. The authors suggest that when fluid pressure increases in these areas, it can cause muscles to feel tight, knotted, and painful—similar to what happens in conditions like ME/CFS and fibromyalgia. According to their hypothesis, releasing this pressure through manual treatment may help reduce symptoms in both the treated area and elsewhere in the body.
Why It Matters
ME/CFS is characterized by widespread myalgia and post-exertional malaise with no clear structural findings on imaging, leaving patients without adequate explanatory models or targeted treatments. This hypothesis proposes a biomechanical mechanism that could explain nonspecific pain, fatigue amplification, and systemic responses to local stress, potentially opening new avenues for understanding and treating the myofascial component of ME/CFS.
Observed Findings
Clinical observation of immediate local and remote changes in muscle tension, asymmetry, and stiffness during Myopraktikk treatment by palpation and visual inspection
Perceived diminishment of muscle knots, trigger points, and fascial tensions during treatment sessions
Apparent systemic responses to localized manual interventions, suggesting interconnected pathways of tension and force throughout the body
Clinical patterns suggesting muscle dysfunction correlates with fluid accumulation rather than permanent structural damage
Inferred Conclusions
Muscle pain, stiffness, and palpable tensions may be dynamic fluid-pressure phenomena rather than static lesions, and may be reversible through appropriate mechanical intervention
Intrafasciomembranal fluid pressure, driven by impaired drainage and overuse, may be a unifying mechanism linking diverse myalgias including ME/CFS, fibromyalgia, and overtraining syndrome
Biotensegrity principles suggest that localized pressure release can produce systemic improvements through mechanical rebalancing of tension networks
Integrating biomechanical, physiological, and psychosocial factors offers a more complete framework for understanding nonspecific myofascial pain without structural findings
Remaining Questions
Can objective measurements of intrafasciomembranal fluid pressure be developed and validated in humans with ME/CFS, fibromyalgia, and control populations?
What This Study Does Not Prove
This article does not provide experimental evidence, controlled trials, or objective measurements to prove the IFMFP hypothesis; it is a theoretical framework based on clinical observations and palpation alone. The study does not demonstrate that Myopraktikk treatment is effective, nor does it establish causality between fluid pressure and symptoms—these remain inferences. No data are presented comparing IFMFP measurements in ME/CFS patients versus healthy controls or other disease groups.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
Does Myopraktikk treatment produce measurable improvements in pain, function, and fatigue in randomized controlled trials with ME/CFS patients?
What specific physiological mechanisms link localized fluid pressure changes to systemic and remote responses, and can these be demonstrated experimentally?
How do psychological stress and thought patterns mechanically translate into altered fascial fluid dynamics and myofascial dysfunction as the authors suggest?
