History of Muscle Energy Technique

From Leon Chaitow, ND DO

Muscle Energy Technique (MET) was developed in the USA by osteopathic physician F Mitchell Sr. who first described MET in 1948, following exposure to the ideas of fellow osteopath, TJ Ruddy [Mitchell 1948]. Ruddy encouraged patients to actively participate in mobilization and manipulative procedures, rather than those processes being purely passive. Refinements of the methods were later developed by Mitchell’s son, F Mitchell Jr., as well as by Czech physician K Lewit, who worked to minimize the amount of force employed, as well as the direction and duration of isometric contractions: the basic MET precursor to subsequent movement or stretch. MET has been refined and systematized since, and has continued to evolve, with contributions by many practitioners from different professions, mainly in the treatment of shortened or weakened muscles and restricted joints.
