A

ruddy (ruddy rapid rythmic resistive duction) in 1914 closed in EENT practice to practice OMT

Q

another way to say post isometric relaxation

A

when the tension is increased in a skeletal muscle, golgi tendon is stretched and then it sends a signal to spinal cord, inhibiting alpha motor neuron activity causing brief relaxation of the muscle.

muscle contraction–> causes increased tension in GTO–> inhibits muscle contraction (relaxes)

25
Post isometric relaxation: ______-->________--->____
muscle contraction--> causes increased tension in GTO--> inhibits muscle contraction (relaxing it)
26
post-isometric relaxation is done how many times for how long?
3-5 times | 3-5 seconds
27
post-isometric relaxation allows us to get through __________ to reach __________
restrictive physiologic
28
[joint mobilization using muscle force] says that hypertonicity can do what?
hypertonicity of a joint can cause distortion of articular relationships and motion loss hypertonicity will compress joints, cause synovial fluid to thin, and joint surfaces to adhere
29
restoration of motion to the articulation in joint mobilization will result in what?
gapping, or reseating of the distorted joint relationships with reflex relationship of the previously hypertonic muscle
30
force of contraction for joint mobilization
30-50 lbs of force
31
respiratory assistance uses what muscular forces
the muscular forces involved in breating may involve direct use of these muscles or motion transmitted to [spine, pelvis, extremeties] due to breathing
32
what does the physician do in respiratory assistance
apply a fulcrum against which the respiratory forces can work
33
what is the force of contraction for respiratory contraction
exaggerated respiratory motion
34
ocucelphalogyric reflex treats what
upper spine and cervical region
35
ocucelphalogyric reflex
tx upper spine and cervical region by JUST moving eyes as the muscles attempt to follow the movment of them. move eyes, go to new barrier. move eyes, go to new barrier.
36
force of contraction of ocucelphalogyric reflex
exceptionally gently
37
recipricol inhibtion
gentile contraction of agonist muscle causes relaxation of antagonistic muscle now we can go to new barrier
38
how can we tx hamstrings use recipricol inhibtion
contract quads (antagonist) to relax hamstrings go to new barrier, go again
39
force of contraction of recipricol inhibtion
only use OUNCES of force to contract
40
when do we use cross extensor reflex
we use cross extensor reflex when the muscle that requires tx is severely injured that we cannot use it
41
idealogy behind crossed extensor reflex
when the flexor in one extremity is contracted voluntarily, the the flexor in the other relaxes and the extensor contracts
42
crossed extensor reflex is typically used in what extremity
lower
43
force of contraction in crossed extensor reflex
OUNCES
44
what is the difference between recipricol inhibition and crossed extensor reflex
sidedness recipricol uses ipsilateral side crossed extensor uses contralateral
45
if a muscle is CHRONICALLY tight, what will its anatagonist be?
loose bc of the golgi tendon m
46
what is isokinetic strengthening
IK strengthening re-restablishes tone and strength in a muscle caused by hypertonicity of the opposing muscle 1st--> stretch m that is chronically tight. antagonist m may go back to normal. if not, use isokinetic strengthening.
47
in IK strengthening, what muscle should you attend to first?
shortened antagonist m
48
how do you follow up with IK Strenthingin
isokinetic contraction concentric contractions are used, where the muscle shortens at a controlled rate
49
force of contraction of ISOKINETIC CONTRACTION
sustained gentile pressure (10-20 lbs)
50
IK strengthing is used for what kind of muscles?
antagonist of muscles that are contronically tight.
51
isolytic lengthening lengthens muscles shortened by...
1. contracture | 2. fibrosis
52
isolytic lengthening can be used in what kind of patients
stroke or cerebral palsy, where they have contractures
53
how do you conduct isolytic lengthening
pt contracts using [concentric isometric contraction] and you lengthen you straighten out contraction
54
force of contraction of isolytic lengthening
30-50 lbs; max that can be contraction
55
using muscle force to move one region of the body to acheive movement of another bone or region
another physiological principle for MET
56
isometric procedures require _____ positioning
careful
57
istonic procedures require _____ positioning
careful
58
isometric procedures require what kind of contraction
light to moderate
59
isotonic procedures require what kind of contraction
hard to max
60
isometric procedures require what kind of counterforce
unyielding
61
isotonic procedures require what kind of counterforce
counterforce that allows a motion that is controlled
62
what happens after contraction in isometric procedures
relaxation
63
what happens after contraction in isotonic procedures
relaxation
64
when do we use MET?
``` balance muscle tone strenghthen weak muscles improve symmetry of motion enhance circulation of body fluis lengthen a shortened, contractured or spastic m ```
65
is met versatile
yessss
66
how tha fuq do we conduct a MET?
1. put the body part you want to tx at the the restrictive barrier 2. tell pt the intensity, duration and direction of muscle contraction 3. doc tells pt to contract the RIGHT muscle 4. doc uses a counterforce equal and opposing pts contraction 5. maintain for 3-5 sec 6. tell pt to relax and doc matches 7 go to next restrictive barrier 8. repeat 3-5 times 9. reeval
67
what can go wrong in muscle NRG (on pt side)
contract too hard, in wrong direction, not long enough, pt does not relax right after contraction
68
what can go wrong in muscle NRG (on operator side)
1. dont control the position of joint relative to barrier (motion of the joint) 2. dont counterforce in right direction 3. dont give good instructions 4. moving to a new joint poisition too soon after pt stops contracting
69
MET contraindications
1. instability of cervical spine 2. low vitality 3. sits that can be worsened by muscle activity 4. eye surgery
70
is MET safe?
yes. if done in the right ways
71
articulatory approaches are also called
springing techniques (move through alot of motion with with low velocity) low velocity/high amplitude
72
articulatory approaches are direct/indirect?
direct
73
articulatory approach sum
uses gentle, repeptive motions to get through restrictive barrier to reach physiological barrier. this can be done on a single joint or entire region
74
articulatory approach can be done on what?
can be done on a single joint or entire region
75
articulatory approaches are well-tolerated for
very ill, arthritic old, infants, patients who CANT cooperate w instructions
76
in articulatory techniques, do we exceed anatomic barrier
no. we just go through restrictive to physiologivc
77
steps of articulatory technique
1. doc moves joint until restrictive barrier is reached 2. gentle but firm force is applied a short distance THRU restrictive 3. repeat rhythimcally, 1-2 secs, woth similar time of relaxation push 2 sec-relax 2 sec- push 2 sec-relax
78
as the pt responds, what will happen to restrictive barrier
it will move position within the physiologic ROM
79
do pts exp discomfort?
yes but a good discomfort
80
when do you stop articulatory tech
until restrictive barrier reaches a new plateau or physiological barrier is reached
81
relative contraindication of articulartory
vertebral artery compromise
82
MET technique is a indirect/direct tech
direct
83
ART technique is a indirect/direct tech
direct
84
MEt activating force
3-5 times, 3-5 secs
85
ART activating force
repeptive physian directed movements
86
MET patient cooperation
required it is a active technique
87
