OPP Test 2 Flashcards
Fascia components
GAGs
glucosamine
hyaluronic acid
chondroitin sulfate
more GAGS
Less GAGS
more water binds=more flexible
less water binds=tightness (aging)
tension on fibroblast
becomes a myocyte
majority of propiriception
in fascial sheaths
CT functions
metabolic, stores E, forms scar tissue
wolffs law
bones (and soft tissue) tend to deform along the lines of force placed on them.
hookes law
any strain/deformation placed on an elastic body is in proportion to the stress placed on it. (shin spilnts)
newtons thrid law
when 2 bodies interact, the force exerted by the first on the second is equal in magnitude and opposite in direction to the force exerted by the second body on the first body.
pascals law
pressure applied to a liquid at rest from any point is transmitted equally in all directions.
MFR releases E in form of
heat, electromagnetic, and piezoelectric (bioelectric) changes.
stress and strain
Stress = the force applied to deform a structure Strain = the resulting deformation
pain is localized
at loose sites as muscles are usually weak and inhibited and then Tight areas are frequently tethered (the joint above and below the laxity are tight)
What has to be involved in creating a tethered or lax site
Hooke’s Law: any strain/deformation placed on an elastic body is in proportion to the stress placed on it.
piezoelectric model
What accounts for the change in energy content
Mechanical tension creates bioelectric current changes that guide the orientation of fibrin and collagen. (scar tension lines)
piezoelctricity
Piezoelectricity is current that is produce by the transformation of mechanical stress to electrical energy.
Piezoelectric substances act as transducers and are able to discharge electrical current when physically stressed.
what does a neg charge stimulate?
Positive charge?
neg=osteoblasts=healing
pos= osteoclasts
goals of MFR
Normalizes ROM across a joint
All of these improve type and arrangement of collagen deposition
MFR relative CI
Fractures open wounds, acute thermal injury soft tissue or bony infections deep venous thrombosis (threat of embolism) disseminated or focal neoplasm recent post-operative states over the site of proposed treatment (wound dehiscence) aortic aneurysm
how much physical activity
a minimum of 30 minutes of moderate- intensity (Walking 1.5-2.0 miles in 30 minutes) aerobic activity 5 days per week
or a minimum of 20 minutes of vigorous- intensity aerobic activity 3 days per week
or a combination of moderate and vigorous exercise 3-5 days per week
how much resistence training
2-3 days per week
how much flexibility
2-3 days a week
fnxn fitness (yoga)
2-3 days per week
if you dont exercise
you smoke
examples of moderate ex
