Principles of MET and ART

Question 1

isolytic contraction

Answer 1

non physiologic

attempted concentric contraction, with an external force causing separation of origin and insertion

Question 2

post isometric relaxation

Answer 2

muscle contraction leads to increased tension in golgi tendon organ leading to inhibition of muscle contraction

Question 3

hypertonicity of musculature across a joint can cause

Answer 3

distortion of articular relationships and motion loss
thje increase in muscle tone tends to compress joint surfaces and results in thinning of itnervening layer of synovial fluid

Question 4

respiratory assitance

Answer 4

the muscular forces involved in these techniques are generated by the simple act of breathing
physician usually applies a fulcrum against which the respiratory forces can work

Question 5

oculocephalogyric reflex

Answer 5

eye movements reflexively affect the cervical and truncal musculature as the body attempts to follow the lead provided by eye motion

Question 6

reciprocal inhibition

Answer 6

when a gentle contraction is initiated in the agonist muscle, there is a reflex relaxation of that muscles antagonist gropu
think ounces, not pounds of pressure
IPSILATERAL

Question 7

crossed extensor reflex

Answer 7

used in extremities where the muscle that requires treatment is in an area so severely injured that it is directly unmanipulable
this form of ME uses learned cross pattern locomotion reflexes engrammed in CNS. wehen the flexor muscle in one extremity is contracted voluntarily, the flexor muscle in the contralateral extremity relaxes and the extensor contracts
CONTRALATERAL

Question 8

isokinetic strengthening

Answer 8

to reestablish normal tone and strength in a muscle weaked by reflex hypertonicity of the opposing muscle group
where asymmetry of ROM exists, there is also the potential for asymmetry in muscle strength
if there is shortening of antagonist muscle, attend ot that first
isokinitic scontractions change length at constant velocity - muscle is permitted to shorten but at controlled slow rate

Question 9

muscle energy indications

Answer 9

balance muscle tone
strengthen reflexively weaked musculature
improve symmetry of articular motion
enhance the circulation of body fluids
lengthen a shortened contractured or spastic muscle group
versatile to use in combo with other OMT
