A MET is classified as a direct and active technique. A patient pushes against the osteopath’s own resistance so that a new barrier of movement can be found.
It is also known as ‘active muscular relaxation techniques’ (Liebenson, 1990). Changes include improved local reflex firing so that the muscles function better.
As a patient then relaxes after contracting against the osteopath, the muscles remain inhibited, allowing the joints improved mobility.
