muscle energy and articulatory principles Flashcards
muscle energy
voluntary contraction of patient muscle in a controlled direction at varying levels of intensity against a distinctly executed counterforce (patient moves away from barrier)
active
-patient contributes to corrective force
direct
-positioned to restrictive barrier
what are the four types of muscle contraction
- isometric - contraction with no distance change between origin and insertion (muscle does not change length)
- concentric isotonic - muscle changes length and shortens, approximating origin and insertion
- eccentric isotonic - muscle changes length and lengthens, seperating origin an insertion
- isolytic - (non- physiologic) attempted concentric contraction with an external force causing separation of origin and insertion (eccentric)
what is the most common form of MET
Post isometric relaxation
-muscle contraction, increased tension in GTO (golgi tendon organ) and inhibition of muscle contraction
what is used in the extremities where the muscle that requires treatment is in an area so severely injured that direct manipulation is not possible
crossed extensor reflex
- form of MET
- -flexor muscle in one extremity is contracted voluntarily and the flexor muscle in the contralateral extremity relaxes while the extensor contracts
- contralateral or opposite side
gentle contraction is initiated in the agonist muscle while there is relation of the antagonist group
reciprocal inhibition
-ipsilateral (or same side)
using eye movements reflexively to affect truncal and cervical musculature
oculocephalogyric reflex
restoration of motion in the joint caused by hypertonic muscles across the joint by reseating the distorted joint relations with reflex relaxation of the previously hypertonic musculature
joint mobilization using muscle force
what techniques is used to reestablish tone/strength in a muscle that was weakened by hypertonicity of the antagonist group
isokinetic strenghtening
- using a constant controlled rate of concentric contraction where the muscle is shortened
- using gentle pressure
what technique is used to lengthen a muscle shortened by contracture and fibrosis
isolytic lengthening
-patient uses force to go against the physician
isometric vs isotonic procesdures
isometric
- light to moderate contraction
- unyeilding counterforce
isotonic
- hard to maximal contraction
- counterforce allows controlled motion
when do you use MET
balance muscle tone strenghten muscles improve symmetry of motion enhance circulation lengthen shortened muscles
what are things that can cause MET to go wrong from the patient side
- contract to hard
- contract in wrong direction
- do not hold contraction long enough
- do not relax after contraction
what are things that can cause MET to go wrong from the physician side
- not controlling the joint
- not giving counterforce in right direction
- not giving accurate instructions
- moving to a new position too soon after the patient stop contracting
what is articulatory approach
“springing technique”
- low velocity with high amplitude
- direct technique/ passive cooperation
- gentle repetitive motion through the restrictive barrier
- used for restrictive barriers in the joints or periarticular tissues (tissue around joints)
T/F
articulatory techniques are well tolerated by arthritic patient, elderly/frail patients, post-op patients, infants or young patients, and patients unable to cooperate with instructions
