Myofascial Release

Osteopathic and bodywork antecedents

An EBSCO Research Starters overview of myofascial release (MFR) traces its background to Andrew Taylor Still, who founded osteopathic medicine in the late 1800s, and to manual techniques that influenced later fascia-focused approaches. The same overview places Mabel Elsworth Todd's work on body movement and fascia, published as The Thinking Body, between the 1920s and 1937, and Ida P. Rolf's development of structural integration in the 1940s. These are the overview's own dates and attributions, and it is a single summary source, so they should be read as a lineage as framed by that author and not as a settled historical chain.

The term and John F. Barnes

According to the same overview, the physician Robert Ward learned myofascial release concepts from Wilbur Cole and Esther Smoot in the early 1950s and coined the term 'myofascial release' in the 1960s. It describes John F. Barnes, a physical therapist, as concentrating on the procedure from the 1960s and developing his own version, the Myofascial Release Approach, which he taught in seminars to other health care professionals. The sources reviewed for this page did not include primary documents by Ward or Barnes, and they do not give a verified account of how many practitioners were trained or how the approaches differ.

How the term is used in research

A 2015 systematic review of randomized trials describes myofascial release as a form of manual therapy that applies a low-load, long-duration stretch to the myofascial complex, intended to restore optimal length, decrease pain and improve function. That review selected studies by whether the phrase 'myofascial release' appeared in the abstract or keywords, which means the research literature groups trials by label and not by a standardized technique. A later systematic review used the phrase 'myofascial release therapy' for the same family of hands-on methods.

'Self-myofascial release' (SMR) is a separate usage in sports and rehabilitation literature. A 2015 systematic review defines it as a self-massage technique using a device such as a foam roll or roller massager. In this literature, the word 'myofascial' is attached to a self-applied tool practice, not to a therapist's hands-on method.

What 'fascia' refers to

Fascia has no single agreed definition. A 2012 review compared three nomenclatures, from the Federative International Committee on Anatomical Terminology (1998), the 2008 British edition of Gray's Anatomy and the 2012 Fascia Research Congress, and found they include and exclude different tissues. A 2019 report on a Delphi consensus process by the Fascia Nomenclature Committee recommended two terms: 'a fascia' for a dissectible sheet of connective tissue, and 'the fascial system' for a body-wide continuum of collagen-containing soft connective tissues that also includes tendons, ligaments and intramuscular connective tissue. Which sense a practitioner means by 'fascia' is therefore not always clear.

Distinction from trigger point therapy

Pressure applied to myofascial trigger points, for example ischemic compression, is described in the research literature as its own manual technique with its own trials and reviews. Trigger point therapy has a separate page in this encyclopedia, and this page does not cover it. The word 'myofascial' also appears in 'myofascial pain syndrome', a diagnosis label used in several of the trials discussed below.

Hands-on sessions

The EBSCO overview describes a session in which the client lies supine while the therapist works against the grain of the muscles without oils or creams, applying light pressure and stretching an area until tension is described as released. It lists traction, static pressure and joint positioning among the methods used. In the eight trials pooled in a 2018 systematic review, therapy lasted 30 to 90 minutes and was given 4 to 24 times over 2 to 20 weeks, which shows how widely protocols vary.

Direct and indirect techniques

The terms direct and indirect appear in the trial literature as labels for styles of technique. A 2008 pilot trial in children with spastic cerebral palsy allowed practitioners to use either direct or indirect methods, together with osteopathy in the cranial field, but it did not report outcomes by technique style. The sources reviewed for this page do not define the two styles or compare them, so no description of how they differ is given here.

Self-applied practice with rollers

Self-myofascial release uses a foam roll or roller massager that the person moves over a muscle group. In the 14 studies of a 2015 review, foam rolling bouts lasted roughly 30 seconds to 1 minute, roller massager bouts from 5 seconds to 2 minutes, and post-exercise protocols 10 to 20 minutes. The authors found no standardized pressure or cadence. A 2024 review describes SMR as used by athletes in warm-ups, cool-downs and workouts.

Uses described for hands-on myofascial release

The EBSCO overview lists myofascial pain syndrome, chronic neck, back, shoulder and hip pain, carpal tunnel syndrome, migraine headaches, temporomandibular joint disorder, venous insufficiency and restoring muscle function after injury among the conditions for which MFR is used. These are uses reported in the overview, and it notes that limited research on effectiveness leaves traditional physical therapy as the preferred option for many providers. The trials gathered in a 2018 review studied lateral epicondylitis, fibromyalgia, low back pain and heel pain, and a 2008 pilot trial studied children with spastic cerebral palsy.

Uses described for self-myofascial release

For foam rolling and roller massagers, the stated aims in the literature are to improve joint range of motion, reduce muscle soreness after exercise and influence performance. A 2015 review frames SMR as a way to enhance a client's myofascial mobility, and the tools are often recommended for home use as part of a broader program.

Hands-on myofascial release

A 2015 systematic review of randomized trials found the literature mixed in both quality and results, and its authors judged recent trials encouraging. A 2018 systematic review was narrower, limited to chronic musculoskeletal pain. It included 8 randomized trials: 2 on lateral epicondylitis (95 participants), 2 on fibromyalgia (145), 3 on low back pain (152) and 1 on heel pain (65). Risk of bias was low in 3 trials and high in 5. Effect sizes in the low back pain and fibromyalgia studies did not reach the minimal clinically important difference for pain and disability. In three other studies, all at high risk of bias, that threshold was reached up to two months of follow-up. The reviewers concluded that current evidence was not sufficient to warrant the treatment in chronic musculoskeletal pain.

A 2008 single-blind pilot trial of 55 children with spastic cerebral palsy reported statistically significant gains in two mobility measures for the osteopathic arm, but that arm combined cranial osteopathy and myofascial release, so the result cannot be attributed to myofascial release alone.

Foam rolling and self-myofascial release

A 2020 systematic review with multilevel meta-analysis of 26 trials in healthy adults found that foam rolling, compared with no exercise, had a positive effect on joint range of motion (standardized mean difference 0.74, 95% CI 0.42 to 1.01) but was not superior to stretching (difference -0.02, 95% CI -0.73 to 0.69). A 2015 review of 14 studies in 260 healthy participants reported short-term increases in range of motion without negative effects on muscle performance and possible attenuation of post-exercise soreness, with no consensus on an optimal program. A 2024 review of 25 articles in 517 athletes reported acute effects on flexibility and range of motion without effects on maximal strength and power, and noted heterogeneity in how SMR was applied.

For repeated use over weeks, a 2022 review of 9 randomized trials with foam rolling programs of at least four weeks found conflicting results for flexibility, mostly no benefit for performance, and unclear effects on recovery. Most of this evidence comes from healthy, often young, participants over short periods and does not address pain conditions.

A mechanical challenge to the tissue-release explanation

The explanation that practitioners often give, that sustained pressure changes fascial tissue, has been challenged on mechanical grounds. A 2008 mathematical model by researchers including Robert Schleip estimated that very large forces, outside the normal physiologic range, would be needed to produce even 1% compression and 1% shear in the fascia lata and plantar fascia. It concluded that palpable sensations of tissue release reported by therapists could not be due to deformation of those firm tissues, though softer tissues such as superficial nasal fascia might deform. This was a theoretical model, not a clinical trial.

Unknowns acknowledged in the literature

The authors of the 2015 foam rolling review wrote that the physiological mechanisms behind reported range-of-motion changes are still unknown. A 2021 review by Helene Langevin notes that deep fasciae are richly innervated with small-diameter fibers that can transmit nociceptive signals, especially with inflammation, and that relationships among fascia mobility, proprioception and myofascial pain are largely unstudied. That review does not evaluate myofascial release itself.

Reported effects and cautions

The EBSCO overview names post-treatment muscle soreness as a possible side effect. It lists burns, wounds, broken or fractured bones, weak or fragile bones, certain deep vein problems and use of blood thinners as situations in which MFR is not recommended. The overview does not give frequencies or cite the studies behind these cautions, so they are best read as consumer-level guidance to discuss with a clinician.

What the reviewed sources do not cover

The 2015 foam rolling review contains no discussion of adverse effects or contraindications, and searches of PubMed for systematic reviews of harms from myofascial release or foam rolling returned none. Absence of reports is not evidence of absence of harm, particularly because the trials involved mostly healthy volunteers and short follow-up. No training standard, professional register or code of ethics specific to myofascial release was verified for this page, and the term is used by physical therapists, osteopathic physicians, massage therapists and others whose training differs.

Pain that is new, severe, progressive or accompanied by numbness, weakness, fever or other concerning symptoms warrants conventional medical assessment. Myofascial release is not a substitute for necessary medical care and should not delay it.
