MET

Question 1

what is a MET

Answer 1

tx method in which the pt m. are actively used on a request, form a controlled position, in a specific direction, and against a distinctly executed counterforce

Question 2

isolytic contraction

Answer 2

m. contraction against resistance while forcing the muscle to lengthen.
operators force is more than the patients force
- lil tears in muscle
- used for fibrotic tissue

Question 3

muscle spindle

Answer 3

sensitive to length change
will contract muscle if stretch to fast
to protect from tear

Question 4

Golgi tendon

Answer 4

extrafusal
sensitive to muscle tension
prevent too much tension
cause relaxation of muscle
prevent tearing or avulsion

Question 5

reciprocal inhibition

Answer 5

antagonist vs agonist muscle

quad contract = signal to h/s to relax

Question 6

autigenic inhibition

Answer 6

after a muscle is contracted, it is automatically in a relaxed state for a brief, latent period

Question 7

crossed extensor reflex

Answer 7

• used in extremities where the muscle that requires tx is in an area so severely injured, that is directly un-manipulable or inaccessible

Question 8

contraindication MET

Answer 8

• acute msk injuries
• unset or unstable fx
• unstable or fused jnt
• vertebral artery or basilar artery pathology
• upper cervical instab
• rheumatoid arthritis
• spondylolysis/spondylolisthesis

Question 9

method 1

Answer 9

engage the restrictive barrier by stretching shortened muscle, then ask shorten muscle to contrcat

go into the restriction and contract in the ease

Question 10

methode 2

Answer 10

contract the weakened and lengthen muscle
(Contract-relax HR)

Question 11

methode 3

Answer 11

engage restrictive barrier by stretching the shorten muscle then ask lengthen/weak muscle to contract
into the restriction + contract into the restriction

Question 12

• steps of muscle energy

Answer 12

1- accurate structural diagnosis
2- localization to the restrictive barrier
3- unyielding counterforce (therapist force = pt force)
4- appropriate patient muscle effort (isometric)
- correct amount of force 20-40%
- correct direction of force
- correct duration of effort (3-7s)
5- complete relaxation after the muscle effort
6- repositioning to the new restrictive barrier
7- repeat (3-5times) (steps 3-6)
8- retest

Question 13

pubic symphysis issues moi

Answer 13

• imbalances btw abdominals and add
• chronic single leg standing

Question 14

most common pubic symphysis issues

Answer 14

R inf pubic
L sup pubic

Question 15

tx order of hip dysfunction

Answer 15

• symphysis pubis
• hip bone shear dysfunction (up slip/down slip)
• SI dysfunction (non-phys sacrum, phys sacrum)
• IS dysfunction (rotation , outflare inflare)

Question 16

muscles that influnce SI dysfunction

Answer 16

• psoas
• piriformis
• glut max
• lat dorsi

Question 17

fryettes laws

Answer 17

neutral range: side bend and rotation opposite

flexion or extension: side bend and rotation the same
