Muscular Energy And Articulatory Principles Flashcards
(21 cards)
Who discovered muscle energy and first formed ideas for it? When?
By T.J. Ruddy in 1914
What was muscle energy first called?
Ruddy’s Rapid Rhythmic Resistive Duction
How does muscle energy work?
It uses rapid, repetitive contractions for 1-2 seconds against resistance
Who was a huge advocate for muscle energy?
Fred L. Mitchell
What occurred in 1970 to Fred Mitchell?
He was going to give up on muscle energy but taught one more lecture at Iowa and 5 of the 6 students became huge advocates for muscle energy
What is muscle energy?
Voluntary contraction of a pt muscle in a controlled direction with varying levels of intensity against a counterforce
What are the two techniques in muscle energy?
A direct vs active technique- direct is pushing into barrier while active is the pt providing the contributing force
Isometric contraction
Contraction of a muscle with no change in the distance between origin and insertion- example is holding an object in front of you- muscle is engaged but not moving
concentric isotonic contraction
Contraction of a muscle with approximation of the origin and insertion - example is a bicep curl
Eccentric isotonic contraction
contraction of a muscle with separation of the origin and insertion- example is the relaxation of a muscle after engaging it
Isolytic contraction
Attempted concentric contraction with an external force causing separation of the origin and insertion- pulling down on a muscle that is trying to contract
Post isometric relaxtion
Most commonly used- The restrictive barrier is engaged, the pt uses counterforce then relaxes- should be able to go further into the barrier
Joint mobilization using muscle force
use about 50 lbs force- a contraction is applied to the muscle that will cause a gapping in the joint to correct the spacing
Respiratory assistance
using exaggerated breathing to correct things in the ribs or even sacrum
oculocephalogyric reflex
using eye movements to engage muscles- the head will try to engage and move when they eyes move
reciprocal inhibition
Gentle contraction is initiated in the agonist and there is a relaxation in the antagonist muscle
crossed extensor reflex
using the contralateral side to get the side that is effected to become less tight. Usually seen in the LE. Will contract the muscles of one leg to get the other muscles to relax naturally
isokinetic strengthening
have them contract the muscle but allow for slow contraction to reestablish normal contraction/relaxation to be established
isolytic lengthening
used for muscle contractures mostly. Separating muscles that are held in constant contracture
muscle force to move one region of the body to achieve movement of another bone or region
example is using sternoclavicular muscle to help with clavicle- using the energy of a muscle to correct a body dysfunction
what are the main differences between isometric and isotonic techniques?
isometric is light to moderate force with unyielding counterforce while isotonic is hard force and the counter force is allowing for more controlled movement of muscle.
