Positional release therapy is, in some ways, like trigger point therapy as it focuses on painful muscle areas. The similarities end there however. Positional release therapy is a relatively new technique which is not necessarily seen as a form of massage. What the therapist does is find the tender point on the body and apply a slight amount of pressure to it. While applying pressure the therapist uses their in-depth knowledge of muscle and skeletal structures to passively move other parts of the body to give, what is essential, a very technical sort of stretch. The muscle relaxes and releases the pressure it is holding as all the other muscles surrounding it compensate for the tension. If done well this technique often releases up to 75% of the discomfort in the area right away (though this can depend on the severity of the tender point).
