Muscle Energy and Articulatory Principles Flashcards
Muscle energy
voluntary contraction of patient muscle in a precisely controlled direction against a distinctly executed counterforce it is an active technique it is a direct technique
isometric contraction
no change in distance between origin and insertion
concentric isotonic contraction
approximation of origin and insertion
eccentric isotonic contraction
separation of origin and insertion
isolytic contraction
non physiologic, attempted concentric contraction, with an external force causing separation of origin and insertion
post-isometric relaxation
most common form of MET muscle contraction–>increased tension in GTO–>inhibition of muscle contraction
joint mobilization using muscle force
hypertonic muscle can compress/distort joint restore motion of articulation results in gapping/reseating
respiratory assistance
exaggerated respiratory motion physician usually applies a fulcrum against which the respiratory forces can work
oculocephalogyric reflex
eye movements reflexively affect cervical/truncal muscles
reciprocal inhibition
when gentle contraction is initiated in the agonist muscle, there is a reflex relaxation of that muscle’s antagonistic group ipsilateral
crossed extensor reflex
uses cross pattern locomotion reflexes in CNS. when flexor in one extremity is contracted, flexor muscle in contralateral extremity relaxes and extensor contracts used in extremities that cannot be directly manipulated (burns/fractures)
isokinetic strengthening
agonist muscles spontaneously increase their strength if the shortened/hypertonic muscles are lengthened further restoration via isokinetic contraction (constant velocity)
isolytic lengthening
lengthen a muscle shortened by contracture/fibrosis effect on myotactic units? max contraction force
isometric vs isotonic
light vs max contraction
articulatory approach
“springing” techniques low velocity/high amplitude direct technique passive technique rhythmic repetitive motions directed by physician
Acute vs. Chronic TART
