A

force normalized over the area on which it acts.

Normal stress is perpendicular to the cross-section

sheer stress is parallel.

Q

what is hysteresis

A

a time lag in the occurrence of two associated phenomena, as between cause and effect; change in energy content

it is the energy lost when the energy returned is not equal to the energy stored and represents residual strain

so when you stretch down to touch your toes you can get farther each time and the longer you hold it

Q

what are GAG’s and their function

A

glycosaminoglycans

generated from fibrocytes in response to motion

HYDROPHILIC (water loving) and determine the relative fluid content of connective tissue

more GAGs = more H20 binds to them so this makes the tissues less stiff

Q

where does 75 percent of proprioception occur? and the remaining 25 percent?

A

in fascial sheaths - so this is why we might treat fascia to improve proprioception

remaining 25 percent occurs in ligaments, tendons, joint capsules and muscle spindle activity

Q

what does joint immobilization or long periods of decreased motion enable the formation of?

A

increased collagen crosslinks causing myofascial connective tissue stiffness

**myofascial adaptations accompany the articular and periarticular motion restrictions and muscle imbalance

Q

what is newton’s third law>

A

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.

Q

what is elastic material

A

The amount of deformation is the same for a given amount of stress
Material returns to its original length or conformation when the stress is removed

20
Q

what is viscoelastic material?

A

Nonlinear properties due to the viscous nature
Magnitude of stress applied is dependent on the rate of loading
Stored mechanical energy not completely returned once stress removed (hysteresis)

21
Q

both elastic and viscoelastic materials can be….

A

stiff, compliant, and brittle

22
Q

what is the area under the curve of a stress vs. strain graph

A

stored mechanical or kinetic energy

think of jumping on a trampoline
the difference of that position compared to the unstrained position represents stored mechanical energy

23
Q

stress- strain curve of a viscoelastic material. what does the slope of the curve mean?

A

slope represents the stiffness of a substance

Applying force to the substance prior to reaching the yield point allows elastic strain = the material can return to its original position without deformation.

Surpassing the yield point leads to plastic deformation = molecular components are permanently displaced.

example would be taking a credit card and bending it too far

24
Q

what is residual strain in a stress vs. strain graph

A

the residual strain occurs due to reorganization at a molecular level after stress has been applied

removed stress and it doesn’t come back along the same line b/c it has been deformed

25
if elastic and plastic zones are exceeded the imparted energy is released as a
FRACTURE oh shit Bone needs strength to be weight-bearing and flexibility to absorb high-impact forces by changing shape without failing and then return to its normal length.
26
bone is ...
a viscoelastic substance weight bearing and flexible
27
what is the mechanical plastic model (viscous model)
apply tensile force | now have changed post load (deformed)
28
what is an elastic mechanical model
pre load and post load look the same! nothing changed, went back to normal
29
viscoelastic model mechanical model?
preload is loaded with tensile force some goes back to how it was (the spring) and some is deformed so some elongation is lost and some is retained after the application of tensile force this is an example of creep
30
what is the tight/loose concept
Pain is typically at loose sites as muscles are usually weak and inhibited Tight areas are frequently tethered Looseness suggests joint or soft tissue laxity so if your left knee gets tight your left ankle would be loose
31
big bandage of fascial continuum model
Emphasizes the fascia Uses the integrity of the fascial continuum to treat proximal to distal fulcrum with leverage torsion and traction respiratory assistance reflexive neurologic reset
32
DEEP fascial lines
deep fascia in the thigh that becomes contiguous with the deep fascia of the pelvis to the torso/abdomen/thorax the entry point at the ankle allows one to pick up the IOM and continue deeply into the pelvis and thorax
33
Bioenergetic model
O'connell Piezoelectric model What accounts for the change in energy content? (hysteresis) Collagen is a Piezoelectric substance in bone and has been shown to affect growth/remodeling of bone Negative charge stimulates osteoblasts Positive charge stimulates osteoclasts Mechanical tension creates bioelectric current changes that guide the orientation of fibrin and collagen.
34
what is piezoelectricity>
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.
35
what is palpatory diagnosis
high-level haptic skill (motor and sensory aspects of hand activities)
36
what are the MFR indications ?
Somatic dysfunctions involving myofascial or other connective tissues
37
what are the goals of myofasical release?
relaxation of contracted muscles release tightness or tethering Decrease oxygen demand Decrease pain Normalize ROM across a joint Restore 3-D functional symmetry DON"T AGGRAVATE HYPERMOBILITY don't make things looser Increased circulation to area of ischemia Increase venous drainage and lymphatic drainage
38
complications of MFR
Exceeding the limits of dysfunctional and injured tissue creates iatrogenic trauma layered on top of the somatic dysfunction and complicates the treatment and healing. Temporary worsening of symptoms may occur the first day or two typical of post-exercise muscle soreness. Older aged or debilitated patients, inflammatory conditions (auto-immune diseases, rheumatic conditions, fibromyalgia) are likely to experience post-OMT flare-ups. Drinking more water, resting, soaking in a hot bath can help.
39
what are the absolute contraindications of MFR
Absence of somatic dysfunction | Lack of patient consent and/or cooperation
40
what are the relative MFR contraindications
``` 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 ```
41
how do you do MFR
Technique is a procedure that utilizes a position, method and an activating force. Static and dynamic movement barriers are released as they are encountered by sequentially loading areas of tightness using compression, traction and twisting
42
what is direct MFR
a myofascial tissue RESTRICTIVE BARRIER IS ENGAGED for the myofascial tissues and the tissue is loaded with a constant force until tissue release occurs. Identifies the restrictive barrier in all planes. Brings the body to the restrictive barrier and applies a corrective force (traction, compression, twist, may also utilize: Respiratory cooperation in the phase which encourages tissue tension Tissue inhibition Oscillation Eye, tongue, jaw, head or limb movements
43
what is indirect MFR
the dysfunctional tissues are guided along the path of least resistance until free movement is achieved. Identifies the position of free motion in all planes = neutral. Brings the body to the neutral place and waits for the body to initiate the corrective action. may also use: Regional compression, distraction, or torsion Tissue inhibition or traction Respiratory cooperation in the phase which encourages tissue relaxation Eye, tongue, jaw, head or limb movements
