Muscle Energy Technique Flashcards
Definition - founder
Greenman
A manual medicine tx procedure that involves the voluntary contraction of patient muscles in a precisely controlled direction, at varying levels of intensity, agains a distinctly executed counterforce applied by the therapist
Other definition
An active and direct technique in which the patient contributes the corrective force
Therefore, the activating force of the technique is intrinsic/patient controlled
MET is used to
Relax tight muscles Reduce muscle spasms Joint mobilization Strengthen weak muscles Re-train appropriate function in a muscle Reduce edema
Objectives of MET
Reduction of adaptive changes in a specific area or entire body
Prepares body to better handle adaptive demands
Addresses pain
Isometric muscle contraction
Distance btw muscle origin and insertion is maintained at a constant
Concentric Isotonic contraction
Muscle’s origin and insertin approximate
Eccentric Isotonic
Muscle tension that allows origin and insertion to separate
Isolytic
Concentration contraction is attempted but an external force applied in the opposite direction causes lengthening of the muscle
Post-isometric Inhibtion
A reduction in muscle tone by a muscle after brief periods during which an isometric contraction has been performed
Autogenic inhibition
Contraction of the agonist wll inhibit the agonist
GTO will detect a change in the muscles tension and will produce an inhibitory effect which relaxes the muscle
Reciprocal Inhibition
During a muscle contraction of a muscle, its antagonist will be inhibited and will subsequently demonstrate reduced tone immediately following the contraction
Contraction of the antagonist will inhibit the antagonist
Inhibitory interneuron
Why one versus other (auto vs recip)
Pain to one muscle over other Patient position (pr therapist position) Maybe try one and not getting patient to relax so try other
In a nutshell
Therapist places joint/tissue in the treatment position
Patient is instructed to contract
Therapist resists the force
Therapist engages new barrier/repeat
Key procedural elements
Determine pressence of assymetries What is causing the asymmetries Completion of accurate assesment Proper placement of patient and joint Identify restrictive barriers Patient comfort Therapise holds joint in treatment position
Anatomic barrier
absolute 100% ROM
Elastic barrier
PROM (all soft tissue tension is taken up_
