The word Amma, which means "push-pull" in Chinese, was applied to a form of Oriental massage dating back five thousand years to the period of the Yellow Emperor. Founded and developed by Korean-born Tina Sohn, Amma Therapy is a highly refined and complex system of bodywork whose techniques and treatment strategies combine the use of traditional Oriental medical principles and a Western approach to organ dysfunction. It utilizes a variety of techniques, sometimes paralleling those found in major forms of therapeutic massage, as well as powerful new points discovered by Tina Sohn.
