Myofascial release involves applying sustained, low-load pressure into soft tissue — typically holding for 90 seconds or longer — with the aim of reducing restriction and improving mobility.
It's a useful technique. The usual explanation of how it works is, however, questionable.
The conventional explanation, and the problem with it
It's commonly described as physically stretching or "releasing" fascia, breaking adhesions and remodelling tissue.
Biomechanical research makes this difficult to sustain. Fascia is extremely strong — the forces required to meaningfully deform dense fascial tissue are far beyond what hands can apply. The sensation of tissue "letting go" under your hands is real, but it's unlikely to be the fascia itself deforming.
A more defensible explanation
Current thinking favours neurophysiological mechanisms:
- Reduced muscle tone via mechanoreceptor stimulation and a change in nervous system output
- Pain modulation through descending inhibitory pathways
- Improved fluid dynamics in the ground substance between tissue layers, affecting glide
- Changed sensory input, altering how the area is perceived and how protectively it's held
The technique works. The mechanism is more likely nervous-system-mediated than structural — and that distinction matters, because it explains why results require reinforcement rather than being permanent.
What it helps with
- Myofascial pain syndrome and persistent trigger points
- Chronic muscular tension, particularly neck, shoulders and low back
- Restricted range of motion where soft tissue is the limiter
- Post-injury or post-surgical tissue restriction
- Reducing guarding around a painful joint before other treatment
What a session feels like
Slow and sustained rather than brisk. Pressure is firm but should stay tolerable — the sensation is usually a deep stretch or ache that gradually eases. If you're bracing against it, it's too much.
Mild soreness for a day afterwards is common.
How we use it
As one technique within soft tissue therapy, alongside instrument-assisted work, active release, and dry needling depending on presentation. Which technique fits depends on the tissue, the irritability, and what you tolerate.
Consistently: the lasting change comes from pairing manual work with loading. Manual therapy creates a window of reduced pain and improved motion; exercise is what makes it stick.
