In addition to their immediate detrimental effects on muscle function trigger points often
|
cluster together and pull on tendons and ligaments causing joint problems and deep pain
|
The tension they cause at joints can result in clicking popping and grating sounds Over time
|
they can contribute to bone spurs pinched nerves and arthritis Trigger points can be seen in

Dr Janet G Travell MD is generally recognized as the leading pioneer in
|
trigger point diagnosis and treatment It has been said that she singlehandedly created this
|
branch of medicine Travell who was the White House physician during the Kennedy and
|
Johnson administrations emphasized that trigger points are demoralizing and devastating to
|
quality of life She called them the scourge of mankind Advancedstage trigger points are the
|
worst They usually present in clusters are the most painful and involve highly warped muscle
|
fibers with large numbers of molecular aberrations In reality most people are practically
|
covered in trigger points from old injuries bad posture poor workout techniques and bracing
|
Muscle Tension Develops at the Molecular Level
|
To better understand trigger points we need a little more background on muscles themselves
|
Muscles are composed of fibers which are themselves made of smaller fibers The thinnest of

those hold sarcomeres in which contraction takes place A sarcomere is a microscopic structure
|
built from two kinds of filamentlike molecules actin and myosin Actin and myosin form
|
interdigitating strands that can be activated When active they move past each other quickly

creating contractile force

|
Millions of sarcomeres must contract to perform even the smallest movement After they
|
contract the sarcomeres relax when their actin and myosin strands are uncoupled from each
|
other and pull apart In healthy muscle actin and myosin wait patiently in a relaxed decoupled
|
state until an impulse from the nervous system tells them to pull past each other again In
|
unhealthy muscle they are stuck Many specialists believe that trigger points start to form
|
when overuse causes actin and myosin to become fixed in an interlocked position This
|
interlocking puts the muscle into a static state of contracture in which the strands no longer

separate and relax

|
Trigger points originate from a few different sources sustained lowlevel contraction
|
sudden muscle overload eccentric contraction when a muscle stretches and contracts
|
simultaneously and gross trauma or injury to the muscle Regardless of the cause trigger
|
points slow blood flow to the muscle and cause oxygen deprivation at the affected site
|
The reduced blood flow then causes sarcomeres to contract further constricting the
|
surrounding capillaries Capillaries normally supply the muscle with blood so when they
|
constrict it leads to reduced circulation or ischemia that impairs many cellular processes
|
Without blood flow chemical waste products from muscular activity start to accumulate
|
Eventually the waste stimulates pain receptors in nearby nerve endings sending pain signals to
|
the brain Active trigger points demonstrate an unusual biochemical mix not seen in healthy
|
tissue It is an acidic milieu containing increased levels of proinflammatory contractile and
|
paincausing substances And remember we draw our very breaths with muscles that are
|
affected by these symptoms
|
Muscle Shortening and Scar Tissue
|
A muscle can change its resting length to adapt to the length at which it is habitually used or
|
positioned Muscles usually become shorter due to prolonged contracture This is known as
|
adaptive muscle shortening and places the muscle in a state of partial contraction It is another
|
pervasive clinical finding that affects every person who has ever lived
|
People confined to long periods of sitting exhibit debilitating shortening of the lower back
|
and hip muscles especially the hip flexors Similarly wearing highheeled shoes causes
|
prolonged plantar flexion of the foot which results in adaptive shortening of the soleus
|
muscles Constant squinting shortens the muscle fibers of the orbicularis oculi narrowing the
|
eyes Straining the sneer causes the muscles that lift the top lip to shrink making the face
|
appear hideous When the muscles in your knees and ankles shorten they leave you vulnerable
|
to sprains and tears Holding a hunched neck posture leads to shortening of the
|
sternocleidomastoid and other muscles in the front of the neck making it very difficult to stop
|
hunching because the decreased length of these muscles pulls the head down As Chapter
|
will explain bracing the muscles surrounding the genitals may play a role in sexual dysfunction
|
There are examples of adaptive muscle shortening in muscles all over our bodies
|
The pressure from prolonged contracture pulls on tendons straining them and distressing
|
the joints when they move Next ligaments and joint capsules retract These changes perturb
|
nerve endings within the muscles and joints causing deepseated pain Muscle shortening also
|
increases wear and tear contributing to inflammatory and degenerative changes such as
|
tendonitis fasciitis bursitis and osteoarthritis Many different tissue types are damaged by
|
strain including articular cartilages connective tissues tendons fascia menisci ligaments and
|
spinal disks
|
Adaptive muscle shortening can be made worse by the accumulation of scar tissue Scar
|
tissue is a very tough inflexible fibrous material that binds itself to strained muscle fibers
|
attempting to draw the damaged fibers together The result is a bulky mass of stiff tissue
|
surrounding the site In some cases it is possible to feel and even see this mass under the skin
|
When scar tissue adheres to muscle fibers it prevents them from sliding back and forth
|
properly limiting the flexibility of a muscle or joint
|
Chapter Recognize Muscular Tension Dormancy
|
Scar tissue tends to shrink and deform the surrounding tissues diminishing strength and
|
making the body feel heavy It tends to adhere to nerve cells leading to chronic pain Existing
|
research has found that scar tissue is weaker less elastic more prone to future reinjury and
|
up to times more painsensitive than normal healthy tissue This results in chronic pain
|
that under most circumstances lasts a lifetime In people who brace the most these effects
|
create visibly apparent postural distortions
