Q

Dense regular CT - description

A

Predominantly collagen fibers
Collagen fibers are all arranged in ONE direction
This provides protection against stress exerted in one direction and allows for more efficient movement

Q

What happens before there is tissue damage to dense regular CT

A

When we put traction or pull on a tendon, part of it is untwisting
If the force is high enough to have tissue damage, there will be some untwisting before there is any tissue damage

25
Dense irregular CT - content
Very high collagen - collagen fibers predominate!
26
Dense irregular CT - fiber arrangement
Fibers are arranged in bundles oriented in two or more directions and without definite structure
27
Dense irregular CT - change
Compared with loose CT, this type of CT is less flexible and is also more resistant to stress!!!
28
When we are doing joint mobilizations, grades 3 and 4, what CT are we trying to effect?
Dense irregular CT
29
Superficial fascia - is where
right beneath the dermis
30
Superficial fascia consists of
Loose irregular CT and adipose tissue
31
Superficial fascia functions to
provide storage for water and fat provide insulation prevent mechanical deformation provide pathway for nerves and blood vessels
32
Superficial fascia - adhesions can affect
circulation lymph drainage nerve conduction Scar adhesions may also be a source of chronic pain
33
Deep fascia is what
Dense sheet of fibrous CT mainly made up of dense regular and dense irregular CT that penetrates and surrounds mm, bones, nerves, and blood vessels
34
Deep fascia provides:
Connection in the form of aponeuroses, ligaments, tendons, retinacula, joint capsules, and septa
35
Deep fascia and manual therapy
Not doing a lot of change to the deep fascia with manual therapy
36
Deep fascia function:
Allows free mvmnts of mm Fills space btw mm and other organs Provides passageways for nerves and blood vessels May provide attachments for mm
37
What types of CT are we trying to affect with MFR
Superficial fascia | Loose irregular CT
38
What types of CT are we trying to affect with joint mobilization
Deep fascia | Dense irregular CT
39
What types of CT are we trying to affect with Soft tissue mobilization
``` Loose irregular (fascia) Dense irregular (muscle) ```
40
What types of CT are we trying to affect with passive stretching
``` Superficial irregular (fascia surrounding mm) Dense regular (tendon) Dense irregular (mm) ```
41
Fascial lines
Theory that there are anterior, posterior, and lateral fascial lines Need to consider the fascia when working with high level athletes
42
Normal healing - scar formation
Inflammatory Granulation Fibroblastic Remodeling
43
Normal healing - scar formation - Inflammatory phase
Histamine reaction | Cells coming in a getting rid of debris
44
Normal healing - scar formation - Granulation phase
Fibroblasts coming in | Slowly healing the wound - might see wound edges come in, or scab coming on
45
Normal healing - scar formation - Fibroblastic
Put down the good stuff | Fibers are coming in
46
Normal healing - scar formation - Remodeling
Wound is closed and healed Scar will still change though - devascularization so see change in color and there is a change in collagen type as well - change from type 3 to type 1 - stronger
47
Normal healing - scar formation - when in the tissue healing process would MFR, joint mobs, passive stretching, STM be most effective
Fibroblastic and Remodeling! | This is when the tissue can take the stress of it
48
Inflammatory reaction and mobility - chronic irritant
Leads to the inflammatory process being activated every time the person is exposed to the irritant Inflammatory process leads to increase in fibroblasts laying down - shrinkage of CT - and then abnormal movements and the cycle continues
49
Theoretical mechanisms of soft tissue dysfunction
Intermolecular crosslinking Lymphatic stasis Immobilization Ground substance dehydration/dec GAGS and proteoglycans Neuroreflexive triggerpoints/ afferent nerve ending - inc sensitivity
50
Theoretical mechanisms of soft tissue dysfunction - Intermolecular cross linking leading to
``` Excessive fibrosis (from the rep. trauma) Immbolization which then leads to inc in cross links and a dec in water ```
51
Theoretical mechanisms of soft tissue dysfunction - lymphatic stasis leads to
fibrosis and adhesion formation
52
Theoretical mechanisms of soft tissue dysfunction - immobilization leads to
Inc rate of degeneration of mature collagen and inc in new immature collagen
53
Stress/Strain curve - Elastic vs. Plastic
Elastic region and then the yield point before going into plastic region At the end of plastic region is failure point and ultimate strain (X) and ultimate stress (Y)
54
Elastic and plastic behavior - elastic behavior is what
Stretching it and then come back, stretch and then come back Ex - stretch hamstrings once and feel better but then run again and feel tight again This is only stretching in the elastic region - is okay, but will not give prolonged change
55
Elastic and plastic behavior - plastic behavior is what
Where you will get prolonged change - the goal is that you load it with force and then it doesn't go back all the way down - need frequency though!!! Repetition is key
56
Material failure summary - what is the difference among materials
All materials will break if the strain is high enough | The difference is in what will happen first
57
Material failure summary - If a material completely recovers from strain, it shows
Elastic deformation
58
Material failure summary - f a material shows permanent deformation following strain, it shows
plastic deformation
59
Material failure summary - Most materials are ____ at low strains
Elastic
60
Material failure summary - At higher strains...
A brittle material will continue to deform elastically until it breaks A malleable or ductile material will deform plastically before it breaks
61
Material failure summary - The stress at which a material's deformation changes from elastic to plastic is known as
the yield stress or elastic limit
62
Material failure summary - The toughness of a material is
the amount of energy it can absorb before it breaks
63
Material failure summary - Changes with age
Dec elastin and dec water Dec water leads to cells being closer together and forming cross-links that then form fibrous tissue Also less ground substance (less water)
64
Using the stress-strain diagram, what are we doing when we apply myofascial release to fascial tissue? With MFR -
We take fascia through elasticity and release and repeat with hopes of dec how much stress has to be applied each time We hope to move into the elastic limit and yield point - so start with elastic and hope to get to early plastic
65
Using the stress-strain diagram, what are we doing when we apply myofascial release to capulse in joint mobilization
Same but the capsule is less compliant so we need to apply higher stress to get strain
66
Using the stress-strain diagram - The greater the viscoelasticity of a substance the
more likely we will get deformation in a shorter period of time! With dec fluid viscosity, elasticity dec and get more stiff
67
What technique would be most effective to gain motion, 1 year post surgery in a pt who had a lung lobectomy with a large transverse scar ant to pos on the lateral chest and difficulty with inspiration from chest wall tightness
MFR Slow long pressures would most likely get into the plastic phase Next would be AROM that allows elongation of the scar
