Myofascial Release Flashcards
fascia
general name for fibrous connective tissue masss that binds together the structures of the body
glucosamine
hyaluronic acid
chondroiton sulfate
GAGs?
glycosaminoglycans
are hydrophilic and take in water
lead to stiff or pliable fibers
types of fascia?
dense irregular
dense regular
adipose
reticular tissue
functions of fascia
packaging
protection
posturing
passageways
can you separate muscle and fascia?
no, they are anatomically inseparable
proprioception?
75% of proprioception occurs in fascial sheaths
-other 25% occurs in ligaments, tendons, joint capsules and muscle spindle activity
function of fascia
adaptations accompany joints
joint immobilization
fluid content and contractile elements within connective tissues
stress
force normalized over the area on which it acts
normal stress is perpendicular to the cross-section
sheer stress is parallel
strain
changes in shape due to stress
stiffness
ration of a load to the deformation/strain it causes (tight concept)
compliance
inverse of stiffness
loose concept
creep
continued deformation (increasing strain) of viscoelastic material under constant load over time; release of stored kinetic energy
hysteresis
time lag in the occurence of two associated phenomena, as between cause and effect, change in energy content
wolff’s law
bones deform along lines of force placed on them
hookes law
strain on elastic body is in proportion to stress placed on it
newton’s 3rd law
force of one object equal in magnitude/opposite direction than force of second object
pascals law
pressure on liquid at rest from any point transmitted equally in all directions
myofascial release mechanisms
change in length and associated changes in energy content (hysteresis)
provides peripheral neuroreflexive alterations in muscle tone and neural facilitation (mechanoreceptors)
external forces applied to fascia facilitate restoration of normal structure and function
pizoelectric
mechanical changes will result in bioelectric signal
elastic
amount of deformation is same for a given of stres
material returns to original length or conformation when stress is removed
viscoelastic
nonlinear properties due to viscous nature
-magnitude of stress applied is dependent on rate of loading
stored mechanical energy not completely returned once stress removed
area under stress/strain curve?
stored mechanical or kinetic energy
slope of stress/strain curve?
stiffness of substance
yield point
forces up to this point allow substance to return to original position
surpassing the yield point leads to plastic deformation - molecular components are permanently displaced
creep
tendency of a solid material to slowly move or deform permanently under influence of stresses
result of long term exposure to stress below yield point
when does creep occur in stress/strain curve?
after plastic elongation in the necking phase
hysteresis
energy lost when energy returned is not equal to the energy stored and represents residual strain
area between curves - energy lost
area under bottom curve - energy recovered
bone
very flexible and strong
viscoelastic?
halfway between elastic and plastic (viscous) models
elastic goes back to first orientation
plastic assumes new orientation
viscoelastic somewhere in between
tight/loose concept
pain typically at loose sites as muscles are usually weak and inhibited
tight areas are frequently tethered
big bandage of fascial continuum model
emphasizes the fascia
use the integrity of fascial continuum to treat
proximal to distal fulcrum with leverage torsion and traction respiratory assistance reflexive neurologic reset
pizoelectric model
mechanical tension causes collagen growth/remodeling via current creation
transducers that discharge electrical current when physically stressed
negative charge?
stimulates osteoblasts
positive charge?
stimulates osteoclasts
palpation
high level haptic skill
treatment with MFR increased when someone has proper?
intention
attention
activation
goals of MFR?
relax contracted muscles release tightness or tethering -decreases O2 demand -decreases pain -normalizes ROM across joint -restore 3D symmetry
increased circulation and drainage
don’t aggravate hypermobility
MFR absolute contraindication?
absence of SD
lack of consent
release
subtle motion palpated by physician
-relaxation, melting, shift of tissues
direct MFR
toward barrier
indirect MFR
away from barrier
absolte contraindications of MFR? (book)
no SD lack of consent acute fractures open wounds dermatitis acute themal injury
long lever?
lower extremity MFR technique
upper extremity MFR technique
