The technique and methods of Trigger Point Therapy were primarily defined and developed by Janet Travell, M.D. Trigger point therapy's primary focus is elimination of myofascial pain syndrome caused by hyper irritable areas in muscles. Because these pain syndromes are often overlooked, Dr. Travell developed the techniques of trigger point therapy to help patients find relief.
Trigger point therapy is performed in several ways. The least invasive is through the application of direct pressure, or ischemic compression to the effected muscle and the trigger point contained therein. Application of a vapocoolant spray in conjunction with stretching of the affected muscle, as well as therapeutic ultrasound may also be used. More invasive methods are available if the myofascial trigger points are unresponsive to the above therapies.
Trigger point involves direct pressure to and stretching of the affected musculature. The amount of force used is dependent on patient tolerance. The technique affects the body by eliminating the accumulation of waste in the muscle. Additionally, trigger point therapy allows for restoration of normal muscle tone and flexibility. Trigger points are generally located through physical examination. Additional methods of detection such as thermal imaging are currently being investigated.
