muscle energy lab

Question 1

MET is what type of osteopathic technique?

Answer 1

direct

Question 2

what is the end goal of MET

Answer 2

muscle relaxation and increased mobility

DECREASE in gamma gain

Question 3

what is the patients force in MET

Answer 3

pure muscle contraction

respiration

use of anatomic and physiologic reflexes

Question 4

where does the treatment of MET start>

Answer 4

at the feather edge of the restrictive barrier

where the barrier is first noted

Question 5

when does MET stop?

Answer 5

when no further change is noted or full physiologic range of motion is obtained

Question 6

what is gamma gain

Answer 6

increased efferent gamma motor neuron activity
due to increased neuron activity that occurs as a consequence of faulty regulation by suprasegment supervision of intrinsic and extrinsic reflex systems

Question 7

what do gamma motor neurons do?

Answer 7

control muscle spindle activity

Question 8

what are muscle spindles, what do they do

Answer 8

control muscle length, motion, position (proprioception)

they house 2-12 intrafusal muscle fibers that attach to extrafusal muscle fibers

type Ia and IIa afferent fibers

Question 9

proprioceptive info is provided to the muscle spindle by primary annulospiral endings and secondary flower spray endings. what is the difference

Answer 9

primary– length and rate of stretch info

secondary - relative muscle length NO RATE of length change information

Question 10

what info does the golgi tendon provide?

Answer 10

supplies info about stretch and tension in muscle tendons

Question 11

floppy muscles

Answer 11

might mean decreased gamma gain

Question 12

tight muscles

Answer 12

might be increase gamma gain

Question 13

golgi tendon receptors– the receptors only transfer info about spindle length in relation to muscle length …. but what can’t they do?

Answer 13

they have no way to send info to the spindle about actual muscle length

soooo the muscle length may be maintained in a shortened position by increased gamma gain because decreased tension is being reported to the spindle

Question 14

what is isometric MET

Answer 14

means the counterforces of patient and doctor equal each other and no length change is permitted by the muscle

Question 15

crossed extensor relfex

Answer 15

when the flexor group of one rgion of the body is contracted , the contralateral flexor relaxes and the contralateral extensor tightens

Question 16

reciprocal inhibition

Answer 16

agonist muscle contraction produces antagonist relaxation because of central nervous system patterning

Question 17

what is post-isometric relaxaiton

Answer 17

the refractory period after a controlled muscle contraction during which proprioceptive and nociceptive feedback is absent
allowing the muscle to be passively stretched without stimulating the myotatic reflex

Question 18

what could you use on a patient that has an acute burn, cellulite or injury that does not allow them to be touched without significant discomfort

Answer 18

using crossed extensor reflex MET on the opposite side

Question 19

how does MET enhance lymphatic and venous circulation and reduce edema and tissue congestion

Answer 19

because muscle contraction pumps fluid through the body

Question 20

absolute contraindications for MET

Answer 20

absence of SD
lack of pt consent or cooperation
young child that cannot comprehend
coma-unresponsive

Question 21

what does the patients contractile force accomplish in the course of met

Answer 21

MET works by causing stretch signal to be sent to the muscle spindle from its receptors during controlled contraction

simultaneously contracting against a force while also controlling length of muscle distracts the muscle spindle receptors with information about changing tension and length that is not actually happening

this allows muscle to return to normal length and range of motion without causing reflex shortening of hypertonic muscle s

Question 22

pt pushes in what direction?

Answer 22

into EASE

Question 23

when the patient does the osteopathic salute, what is going on?

Answer 23

instruct the patient to contact the back of their neck with their hand that corresponds to the side of the rotation

so if the dignosis is T9 NSLRR put their RIGHT hand on the back of their neck

Question 24

understand the final corrective motion applied by the physician to complete MET

Answer 24

place back in neutral

Question 25

when you are using the osteopathic salute, what is the difference in the doc’s arm positioning with type I and type II

Answer 25

for type I reach under the patients left (horizontal) humerus (arm closest to the doc) and contact the right (up) humerus or elbow

for type I reach over the patients arm that is not connected to their neck

Question 26

for iliopsoas dysfunciton what side of the table do you stand on to treat

Answer 26

dysfunctional side

Question 27

oculocephalogyric reflex

Answer 27

use of eye motion to stimulate contraction of cervical and truncal muscle groups

Question 28

respiratory assistance

Answer 28

use of muscles of respiration to engage the muscles directly or transmit motion to the rest of the body (breathing increased tensikon in pelvic floor during inspriation) in order to provide the patient force against the physicians fulcrum

Question 29

joint mobilization using muscle force

Answer 29

the restoration of full and normal rom results in gapping or rebalancing synovial pressures within a joint and its attachments causing relaxation to dysfunctional and hypertonic tissues

Question 30

isokinetic strengthening

Answer 30

asymmetry in rom can cause asymmetry of strength

restoring strength and balacne to agonist/antagonist muscles can be achieved by first lengthening the antagonist muscle then using isokinetic contraction to finish treatmetn

Question 31

isolytic lengthening

Answer 31

this technique may affect myotatic feedback and ciruculatoin to the treated area

Question 32

using muscle force of one region to move another region

Answer 32

moving one part of the body can affect another part of the boydy (tensegrity) therefore, a dysnfucational area may be effectively treated by using forces created while treating an adjacent body part
