Effects
- Clients often report feeling looser and moving more freely after massage
- Small short-term gains in flexibility have been measured after massage
- Therapists often feel tissue "soften" or "release" under the hands during slow sustained pressure
- Laboratory and modelling studies do not show that hand pressure changes the length or stiffness of dense fascia or muscle
What fascia is
Fascia is connective tissue made mostly of collagen fibres. It forms a continuous three-dimensional web through the body:
- Superficial fascia sits just under the skin, mixed with fat.
- Deep fascia is denser. It wraps muscles and groups of muscles, for example the tough fascia lata around the thigh.
- Fascia also surrounds individual muscle fibres, bundles of fibres, nerves, vessels and organs, and helps transmit force between neighbouring muscles.
Fascia contains many sensory nerve endings, so it is part of how we sense movement, position and pain.
What massage probably does and doesn’t do
A common claim is that massage “breaks down adhesions”, “melts” or “lengthens” fascia. The evidence does not support this:
- A modelling study calculated that very large forces, far beyond normal hand pressure, would be needed to change dense fascia such as the fascia lata or plantar fascia by even 1%. Softer, superficial fascia deforms more easily.
- A 2026 meta-analysis of 25 trials found massage did not acutely change the stiffness of muscles, tendons or the muscle–tendon unit.
So why do clients feel looser, and why do therapists feel tissue soften? The most likely explanation is the nervous system: pressure and stretch change muscle tone and how the brain interprets sensations from the area (see Muscle tone and flexibility and Pain, the pain gate and the nervous system). The tissue feels different because the person is holding it differently, not because it has been reshaped.
Myofascial release
Myofascial release (MFR) is a beyond-scope technique using slow, sustained pressure and stretch. Trial results are mixed: one review was encouraging, while a stricter review of chronic musculoskeletal pain found the evidence too weak to recommend it.
How to talk about it with clients
- Say: “Slow, sustained pressure like this often helps an area feel less tight.”
- Avoid: “I’m breaking up your adhesions” or “your fascia is stuck.”
