trigger points represent a major cause of sustained pain, as well as muscular, nervous system, and soft tissue dysfunction.
Extensive research and experiential results show that all chronic pain conditions produce trigger points.
Trigger Point Therapy is a proven technique used for the relief of soft-tissue pain and dysfunction. It is used by many healthcare
practitioners, including medical doctors, osteopaths, chiropractors, and massage therapists. Often called a Neuromuscular
Technique (NMT), NMT actually encompasses a broader set of treatment approaches.
trigger points represent small areas of tightness within muscles, creating tight bands and "knots" or tiny bumps from the
contracted muscle fibers. Current literature indicates that nerve impulses to these muscle fibers will not "shut off" and
that myofascial trigger points require some form of manual intervention to help them release.
trigger points cause discomfort when pressed; however, "active" trigger points frequently refer pain to other areas of the
body. As a result, many therapists address the site of the pain, or the symptoms of trigger points, rather than the real problem
area, or the site of the trigger point. Pressure to an active trigger point will typically refer the sensation or symptoms
to a distinct and predictable target area. In addition to pain, the effects of an active trigger point can include:
- Limited range of motion
- Muscle weakness
- Numbness or tingling
an active trigger point refers pain to reference sites, it may invoke satellite, or secondary trigger points. As a result,
acute conditions tend to turn chronic.
medicine, documented research on trigger points dates back to 1841. However, most references give credit to Janet Travell,
M.D., for the most extensive clinical research on Myofascial Trigger Point Therapy. Dr. Janet Travell was the White House
physician during the Kennedy and Johnson administrations. She treated President Kennedy for debilitating myofascial pain that
threatened to end his political career before he entered the White House. Janet Travell first coined the term "myofascial
trigger point" in print in 1942. She co-authored several books with David Simons, MD, who continues to promote research about
trigger points and to update their works as more research and information surfaces. Most people consider these books the definitive
reference on trigger point therapy.
generic definition for Myofascial Trigger Point Therapy would be specific ischemic pressure. This involves pushing a point
on the body hard enough to stimulate the nervous system and increase circulation to the area. Western research indicates an
80% overlap between myofascial trigger point and acupressure point sites on the body. In Oriental medicine, practitioners
have practiced acupressure to relieve pain for thousands of years. Leon Chaitow, O.D. has published a great deal of information
on European-based NMT and trigger point therapies. He recently joined with American NMT practitioners to publish more comprehensive
references on NMT and Myofascial Trigger Point Therapy, incorporating both American and European techniques.
form of Western trigger point therapy is Periostal Trigger Point Therapy, also known as Periostal Massage. It focuses on the
connective tissue that surrounds bone tissue - the periosteum. In the 1950's, Periostal Massage was recognized as an independent
procedure of medical massage. Disease to the joints and inner organs cause pathological changes in the periosteum, such as
local thickening and roughness.
effects of Periostal Massage include:
- Elimination of local pain
- Improved circulation to the periosteum
- Delayed degeneration of joints
- Improved function of specific inner organs
Trigger Points may also cause local pain at the trigger point sites.
