Soft Tissue and Myofascial Release Techniques Flashcards
Fascial Anatomy
Generally speaking, these connective tissue layers are
composed of collagen fibers (and occasionally also
elastin fibers) in an amorphous matrix of hydrated
proteoglycans (PGs), which mechanically links the
collagen fiber networks in these structures.
EMC 95%, Cells: 5%
Fascia
A complete system with blood supply,
fluid drainage & innervations – Thus, fascia comprises the largest organ system in the body
• Composed of irregularly arranged fibrous
elements of varying density
• Fn: Involved in tissue protection &
healing of surrounding systems
Fascia is not:
Tendons
• Ligaments
• Aponeuroses
Continuity of Fascia
Perimysium (fascia), peritendium, periosteum
Pannicular Fascia (aka Panniculus)
Outermost layer of fascia derived from somatic
mesenchyme & surrounds entire body with
exception of the orifices; outer layer is adipose
tissue & inner layer is membranous & adherent,
generally, to the outer portion
• Axial & Appendicular Fascia (aka investing layer)
• Meningeal Fascia
• Visceral Fascia
Axial & Appendicular Fascia (aka
investing layer)
Internal to the pannicular layer; fused to the
panniculus and surrounds all of the muscles, the
periosteum of bone & peritendon of tendons
Meningeal Fascia
Surrounds the nervous system; includes
the dura
Visceral Fascia
Surrounds the body cavities (pleural,
pericardial & peritoneum
Viscoelastic Material
Any material that deforms according to rate of loading and deformity
Stress
s is the force that
attempts to deform a connective
tissue structure.
Strain
is the percentage of
deformation of a connective
tissue.
During cyclic loading of tendon, the stress-strain
curve gradually shifts to the right
Hysteresis
The difference between the loading and unloading characteristics represents energy that is lost in the connective tissue system; this energy loss
Stretching connective tissue into its’
plastic deformational range will
bring about a lengthening of the
tissue.
Creep
Connective tissue under a sustained, constant load (below failure
threshold), will elongate (deform) in response to the load.
Ease
The direction in which the connective tissue may be moved most
easily during deformational stretching.
• Palpated as a sense of tissue “looseness”, or laxity or greater degree
of mobility.
Wolff’s Law
“Bone will develop according to the under stresses placed upon it.” • This concept extends to fascia, too.
Somatic Dysfunction
Impaired or altered function of: – Skeletal, – Arthroidal, and – Myofascial structures, and their related – Vascular, – Lymphatic, – Neural elements
Sherrington
’s Law:
When a muscle receives a nerve impulse to contract, its antagonists receive an impulse to relax.
