Chapter 15 ME Basics Flashcards
What kind of technique is ME?
Active direct or active indirect (rarely)
Where does the physician initially place the pt for ME?
Directly into the barrier
What is isometric contraction?
Distance bt origin and insertion of muscle remais the same as the muscle contracts (but internal CT will stretch)
What does this isometric contraction cause the golgi tendon to do?
Change tension and causes reflex relaxation of agonist muscle fibers allowing the doc to further engage the barrier
What is reciprocal inhibition?
When antagonist muscles contract, the agonist muscles will reflexively relax
How can reciprocal inhibition be done?
Directly or indirectly
How would you tx a biceps m spasm using direct reciprocal inhibition?
Extend elbow to restrictive barrier, have pt contract triceps against resistance
How would you tx a biceps in spasm using indirect reciprocal inhibition?
Fully flex elbow (away from restrictive barrier), have pt contract triceps against resistance
What is teh oculocephalogyric reflex?
Uses EOM contraction to reflexively effect the cervical and truncal musculature
What is the crossed extensor reflex?
When reflex occurs, the flexors in withdrawing limb contract and extensors relax, while in the other limb the opposite occurs
How long is ME maintained?
3-5 secs
How many times is ME repeated?
3-5 times
What is more important, localization of force or intensity of force?
Localization
What barriers must be engaged during ME?
The restrictive barrier in ALL planes of motion
When is ME contraindicated?
Post-surgical pts and intensive care pts
