Q

When did we first hear about MET

A

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

first saw MET when he did eye and cervical spine tx. he used rapid, repeptive contractions for 1-2 sec against resistance of eye

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)

Q

[joint mobilization using muscle force] says that hypertonicity can do what?

A

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

Q

ocucelphalogyric reflex

36
Q

force of contraction of ocucelphalogyric reflex

A

exceptionally gently

37
Q

recipricol inhibtion

A

gentile contraction of agonist muscle causes relaxation of antagonistic muscle

now we can go to new barrier

38
Q

how can we tx hamstrings use recipricol inhibtion

A

contract quads (antagonist) to relax hamstrings

go to new barrier,
go again

39
Q

force of contraction of recipricol inhibtion

A

only use OUNCES of force to contract

40
Q

when do we use cross extensor reflex

A

we use cross extensor reflex when the muscle that requires tx is severely injured that we cannot use it

41
Q

idealogy behind crossed extensor reflex

A

when the flexor in one extremity is contracted voluntarily, the the flexor in the other relaxes and the extensor contracts

42
Q

crossed extensor reflex is typically used in what extremity

A

lower

43
Q

force of contraction in crossed extensor reflex

A

OUNCES

44
Q

what is the difference between recipricol inhibition and crossed extensor reflex

A

sidedness

recipricol uses ipsilateral side

crossed extensor uses contralateral

45
Q

if a muscle is CHRONICALLY tight, what will its anatagonist be?

A

loose bc of the golgi tendon m

46
Q

what is isokinetic strengthening

A

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
Q

in IK strengthening, what muscle should you attend to first?

A

shortened antagonist m

48
Q

how do you follow up with IK Strenthingin

A

isokinetic contraction

concentric contractions are used, where the muscle shortens at a controlled rate

sustained gentile pressure (10-20 lbs)

50
Q

IK strengthing is used for what kind of muscles?

A

antagonist of muscles that are contronically tight.

51
Q

isolytic lengthening lengthens muscles shortened by…

A
  1. contracture

2. fibrosis

52
Q

isolytic lengthening can be used in what kind of patients

A

stroke or cerebral palsy, where they have contractures

53
Q

how do you conduct isolytic lengthening

A

pt contracts using [concentric isometric contraction] and you lengthen

you straighten out contraction

54
Q

force of contraction of isolytic lengthening

A

30-50 lbs; max that can be contraction

55
Q

using muscle force to move one region of the body to acheive movement of another bone or region

enhance circulation of body fluis
lengthen a shortened, contractured or spastic m
65
Q

is met versatile

A

yessss

66
Q

how tha fuq do we conduct a MET?

A
  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
  7. repeat 3-5 times
  8. reeval
67
Q

what can go wrong in muscle NRG (on pt side)

A

contract too hard, in wrong direction, not long enough, pt does not relax right after contraction

68
Q

what can go wrong in muscle NRG (on operator side)

A
  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
Q

MET contraindications

  4. eye surgery
70

low velocity/high amplitude

72
Q

articulatory approaches are direct/indirect?

A

direct

73
Q

articulatory approach sum

A

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
Q

articulatory approach can be done on what?

A

can be done on a single joint or entire region

75
Q

articulatory approaches are well-tolerated for

A

very ill,

arthritic
old,
infants,
patients who CANT cooperate w instructions

76
Q

in articulatory techniques, do we exceed anatomic barrier

A

no.

we just go through restrictive to physiologivc

Q

steps of articulatory technique

A
  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
Q

as the pt responds, what will happen to restrictive barrier

A

it will move position within the physiologic ROM

79

do pts exp discomfort?

A

yes but a good discomfort

80
Q

when do you stop articulatory tech

A
