Based on the discoveries of Drs. Janet Travell and David Simons in which they found the causal relationship between chronic pain and its source, myofascial trigger point therapy is used to relieve muscular pain and dysfunction through applied pressure to trigger points of referred pain and through stretching exercises. These points are defined as localized areas in which the muscle and connective tissue are highly sensitive to pain when compressed. Pressure on these points can send referred pain to other specific parts of the body.
