What is myofascial release? What is known about fascia

Fascia is a thin layer of connective tissue surrounding muscles, vessels and organs. It forms a continuous network and allows muscles to glide against one another.

This tissue contains abundant nerve endings. Its role in producing pain has become better understood in recent years, after long being regarded as a merely mechanical wrapping.

After immobility, repetitive strain or injury, the glide between fascial layers can reduce. That reduction shows itself as restricted movement and a sense of tightness.

Application means sustained, progressive pressure to the target area by hand or with a tool. Pressure is held slowly and steadily rather than rubbed quickly.

Duration is what distinguishes the method. Pressure is held between thirty seconds and two minutes; brief application does not produce the intended effect.

The patient breathes freely and pressure stays below the level that produces pain. Very firm pressure increases protective muscle tension and works against the aim.

There is reasonable evidence that myofascial release reduces pain and increases range in the short term. In most studies that effect lasts hours to days.

Whether the effect comes from the fascia physically lengthening or through the nervous system has not been fully explained. Clinically the outcome is the same, but claims should reflect that uncertainty.

There is no evidence it is sufficient alone for a lasting long-term effect. The method is therefore used alongside an exercise programme rather than in place of one.
