MET and ART Flashcards
(22 cards)
Muscle Energy
Voluntary contraction of patient muscle in a precisely controlled direction
Varying levels of intensity
Against a distinctly executed counterforce
Active Technique
Patient contributes the corrective force
Direct Technique
Positioned to the restrictive barrier
Isometric Contraction
Contraction of a muscle with no change in distance between the origin and insertion
Concentric Isotonic Contraction
Contraction of a muscle with approximation of origin and insertion
“curl part of a bicep curl”
Eccentric Isotonic Contraction
Contraction of a muscle with separation of origin and insertion
“the relaxation part of the bicep curl”
Isolytic Contraction
Non-physiologic
Attempted concentric contraction, with an external force causing separation of origin and insertion
Post-isometric Relaxation
Most common form or MET
muscle contraction->Increased tension in Golgi tendon organ->inhibition of muscle contraction
Golgi tendon organ (GTO)
Joint Mobilization Using Muscle Force
Hypertonicity of musculature across a joint can cause distortion of articular relationships and motion loss
This increase in muscle tone tends to compress the joint surfaces and results in thinning of the intervening layer
Respiratory Assistance
The muscular forces involved in these techniques are generated by the simple act of breathing
Oculocephalogyric Reflex
These eye movements reflexively affect the cervical and truncal musculature as the body attempts to follow the lead provided by eye motion
Reciprocal Inhibition
When a gentle contraction is initiated in the agonist muscle, there is a reflex relaxation of the muscle’s antagonistic group
Crossed Extensor Reflex
Used in the extremities where the muscle that requires treatment is in a area so severely injured that it is directly unmanipulable or inaccessible
Flexion in one extremity causes relaxation in contralateral flexor and contraction of extensor of that same extremity.
Isolytic Lenghtening
To lengthen a muscle shortened by contracture and fibrosis
It is postulated that the vibration used here has some effect on the myotatic units in addition to mechanical and circulatory effects.
Muscle force to move one region
For some dysfunctions it is more effective to move one body structure by moving another body structure adjacent to it. Muscular force is used to move the first structure and the body part’s response to the muscle force is transmitted
MET Indications
Used to: balance muscle tone, strengthen reflexively weakened musculature, Improve symmetry of articular motion, enhance the circulation of boy fluids, lengthen a shortened contracted or spastic muscle group
MET sequence
The physician positions the body apart to be treated, at the position of initial resistance.
The patient is instructed in the intensity, duration, and direction of the muscle contraction
the physician directs the patient to the contract the appropriate muscles of muscle group.
The physician used counterforce in opposition to and equal to the patients muscle contraction
The physician maintains forces until an appropriate patient contraction is perceived at the critical articulation
Fuck it
MET Contraindications
Local fracture
Local dislocation
Moderate-to-severe segmental instability in the cervical spine
Evocation of neurologic symptoms or signs on rotation or the neck
Low vitality
Situations that could be worsened by muscle activity
Unable/unwilling to follow verbal commands
Articulatory Approach
Gentle and repetitive motions through the restrictive barrier to restore physiologic motion
Applicable with the restrictive barrier is in the joint or periarticular tissues
Can be applied to vertebral as well as extremity somatic dysfunction.
May be used on single joint, or an entire region
ART Indication
Well tolerated by: arthritic patients, elderly or frail, critically ill or post-operative patients, infants or very young patients, patient unable to cooperate with instruction w
Isotonic vs. Isometric
Isotonic requires -Hard to maximal contraction with a counterforce that permits controlled motion.
Isometric-light to moderate contraction with an unyielding contraction.
Differences between MET and ART
ART is a passive technique where the patient is relaxed. MET is an active technique where the patient resists opposite the barrier
Both are direct
