38
define hypomobile
Motion stops short of anatomical limit at pathological point of limitation
Pain, spasm, adhesions, inflammation
39
define hypermobile
Joint moves beyond its anatomical limit because of laxity of surrounding structures
40
Manual therapy techniques involving movement of articulating surfaces with intention of:
```
Regaining normal ROM
Improving joint capsule extensibility
Regaining normal distribution of forces and stresses on a joint
Reducing pain
Lubricating joint surfaces
Providing nutrition to joint structures

44
joint mkobs help biomechanixs how
Motion improvement
Positional improvement
Increase joint capsule extensibility
45
joint mobs nutritional effects
Synovial fluid movement
| Improve nutrient exchange
46
joint mobs neurophysiological
Stimulates mechanoreceptors to inhibit pain impulses
gate control and descending pain pathway
47
gate control theory
Gate control theory
| Slow pain signals are getting to the brain faster so that the pain signals are unable to get into the brain
48
brain
| Descending pathway inhibition theory
(primarily related to grade V mobilizations/manipulations)
| Grade 5 manips: stimulate the periaqueductal gray area for pain modulation
49
stress strain curve
Toe- taking up the slack
Yield: stretch but come back to normal
Plastic region: good amount of stress to make a permanent stretch
50
joint play mvm
compression
traction/distraction
gliding
51
compression joint mobs
approximation of joint surfaces; force perpendicular to joint plane
Improves stability
52
traction/ distraction joint mob
separation of joint surfaces; force perpendicular to the joint plane
Pulling away from the joint surface perpendicular
People who have rubbing love distraction
53
gliding
force direction parallel to joint surface
54
how many grades are there for distraction
3
55
Distraction
grade I
piccolo (loosen)
Very small amplitude of traction force
Minimal stress on the joint capsule
Reduces compression forces on articular surfaces
Pain reduction
Commonly used with gliding mobilizations
56
Distraction
Grade II
slack (take up the slack, “tightening”) in elastic
phase
Slack in joint capsule and surrounding tissues is taken up
Can help to determine the sensitivity of the joint
Used to alleviate pain, assess joint play, and/or reduce muscle guarding
57
Distraction
Grade III
stretch
Designed to stretch joint capsule and soft tissues surrounding the joint to increase mobility
Used to assess end feel or increase movement
58
how many grades for oscillation grades
5
59
Oscillation
Grade I
Small amplitude technique performed at beginning of available ROM (first 25%)
Primary goal:
reduce pain and muscle guarding
improve joint lubrication/nutrition
60
Oscillation
Grade II
Large amplitude technique performed in middle of available ROM (middle 50%; 25-75%)
Primary goal:
reduce pain and muscle guarding
improve joint lubrication/nutrition
61
oscillations
Grades I and II summery and theory
Pain relief and muscle guarding
No direct mechanical effect on restrictions
Influences mechanical nociception
Often used before and after grade III and IV mobilizations
Theory:
Reduces pain by improving joint lubrication and circulation to tissues related to the joint
Rhythmic oscillations possibly activate articular and skin mechanoreceptors which play role in pain reduction
62
oscillations
Grade III
Large amplitude technique performed at end of available ROM (last 50%; 50-100%)
Primary goal:
stretching joint capsule and associated structures (ligaments, muscles attaching in the area)
63
Oscillations
Grade IV
Small amplitude technique performed at end of available ROM (last 25%; 75-100%)
Hovering at end range w/ small mvm
Primary goal:
stretching joint capsule and associated structures (ligaments, muscles attaching in the area)
ONLY ON HYPOMOBILE that is not hypermobile correction
Assess the mvm at all times to make sure they are not normal and assess what grade do they need that day
64
summery of grade III and IV fxn
Primarily stretching techniques
Mechanical and neurophysiological effect
May activate inhibitory joint and muscle spindle receptors to aid in reducing restriction of movement
65
Oscillations
Grade V
High velocity thrust of small amplitude at end of available range but within its anatomical range
Movement that exceeds the resistance barrier
Commonly referred to as high velocity thrust technique or joint manipulation
Primary goal:
decrease pain and muscle guarding
66
Oscillations Grade V summery
Similar to grade IV in terms ofamplitude and position in joint range, but difference in velocity
Applied to barrier or point of joint restriction
Involves application of fast impulse (quick thrust) of small amplitude (short distance)
Joint briefly forced beyond restricted ROM
67
joint mobs types
Distractions
Oscillation mobilizations
Sustained hold mobilizations
Manipulations
68
target impairments for oscillation mobs and manips
guarding, pain, joint hypomobility
Address extensibility
Must consider stress-strain curve of
collagen tissue when considering efficacy of joint mobilization for improved joint mobility
69
sustained hold mobs target impairments
joint mobility, pain
Pain:
beginning range to mid range
Joint mobility:
end range
Address tissue extensibility directly to allow motion (when enough force applied for enough time according to stress-strain curve for collagen)
70
joint mobs technique
```
Resting position used for:
Assessment
Acute stage
During grade I and II oscillations
Can be used during grades III and IV if this is the only position patient can tolerate
```
When attempting to improve ROM (grades III and IV) should place joint at
end ROM if tolerable
One half of joint should be stabilized,
while other half is mobilized
71
technique for mobs the therapist positions should be
Both stabilizing and mobilizing hands should be as
close as possible to the joint line
Clinician’s hands should make
maximum contact with patient’s body
72
in what direction do you apply a joint mobs
Based on convex concave rule and which part of joint is being mobilized and which is being stabilized
73
goal time and ocillations per second
1-3/seconds
Typically:
1-5 sets for 15-60 seconds each
74
goal sustained hold times
Typically:
1-5 sets for 5-30 seconds each
More commonly used to treat ROM
75
tips for PTs applying mobs
Allow gravity to
assist when possible
Your body and the mobilizing part should act as
one unit as much as possible
Body
mechanics!!!
When possible your forearm should align with the
intended direction of your force
Reassess afterwards
Stop for the day when a large improvement has been
obtained or when improvement ceases
76
How do I know what direction to push for joint glides?
ARTHROKINEMATICS
CONVEX/CONCAVE RULE
CONCAVE/CONVEX RULE
77
Grade I and II mobilizations direction is
Direction less important as
not stretching the joint capsule
Trying to stimulate the gate control theory
Perform grade I and II in direction which
initially caused their pain if tolerated
```
Often done in
open pack (resting) position
```
78
direction of Grade III and IV
Determine what motion you want to improve and the direction of the osteokinematics (ie hip extension)
Determine what joint you are going to mobilize (ie hip joint)
Determine which part of the joint you are going to mobilize which part is going to be stationary (ie femur=mobilizing, acetabulum=stationary)
Determine if bone mobilizing is convex or concave (femur=convex)
Convex on concave=mobilize opposite direction as osteokinematics; if concave on convex=mobilize in same direction as osteokinematics
If tolerated should mobilize at the end range (where restriction likely is)
79
most often therapist mobilize
distal part of the joint and stabilize the proximal portion
80
Mulligan’s Mobilization with Movement (MWMs) type
combined sustained joint mobilization applied by therapist while patient performs active movement to end range
81
mulligans golden rule
Golden rule of MWMs should be painless,
| if pain occurs either need to change direction of force, correct pressure, or not use MWMs
82
MWM's theory
bony positional faults contribute to painful joint restrictions
83
MWM's guidelines
Should be
pain free when performing
Apply
10 times before reassessing joint motion
Overpressure
should be applied at end range of AROM
