Principles Of MET Flashcards
Isometric contraction
Contraction of a muscle with no change in distance between origin and insertion
Concentric isotonic contraction
Contraction of a muscle with approximation of origin and insertion
What is muscle energy
The voluntary contraction of a patient muscle in a precisely controlled direction with varying levels of intensity against a distinctly executed counterforce
What is the active technique for MET
Patient contributes to the corrective force
What is the direct technique for MET
Positioned to the restrictive barrier
What is isometric contrction
Contraction of a muscle with no change in distance between the origin and insertion
What is concentric isotonic contraction
Contraction of a muscle with approximation of origin and insertion
What is eccentric isotonic contraction
Contraction of a muscle with separation of origin and insertion
What is isolytic contraction
Non-physiological
Attempted concentric contraction with an external force causing separation of origin and insertion
What is the most common form of MET
Post-isometric relaxation
What is post-isometric relaxation
Muscle contraction - increased tension in GTO - inhibition of muscle contraction
What are the indications for MET
Balance muscle tone
Strengthen reflexively weakened muscles
Improve symmetry of articular motion
Enhance circulation of body fluids
What are the four factors that can influence a wrong MET (patient)
- Contact too hard
- Contact in wrong direction
- Sustain the contraction for too short a time
- Do not relax appropriately following contraction
What factors influence an incorrect MET (operator)
Not controlling the joint position in relation to the barrier movement
Not providing the counterforce in the correct direction
Not giving accurate instructions
Moving to a new joint position too soon
What are some contraindications for MET
Local fracture Local dislocation Instability in CS Low vitality Can not follow commands Neurological symptoms
