Lecture 7: Muscle Energy Flashcards
T.J. Ruddy, DO
Ruddy’s Rapid Rhythmic Resistive Duction 1914= first published article Eye and cervical spine treatment Used rapid, repetitive contractions 1-2 per second against resistance
Fred L. Mitchell, Sr., DO
Wrote about Muscle Energy Technique as early as 1948
has developed and amplified MET
Muscle energy
Voluntary contraction of patient muscle
Varying levels of intensity
In a precisely controlled direction
Against a distinctly executed counterforce
Muscle energy- active technique
Patient contributes the corrective
force
Muscle energy-direct technique
positioned to the restrictive barrier
in muscle energy which was it patients motion?
Patient’s motion is away from the 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
- The “Curl” part of the biceps curl
Eccentric isotonic contraction
Contraction of a muscle with
separation of origin and insertion
-(Like the relaxation phase of a bicep curl)
“Isolytic” contraction
Attempted concentric contraction, with an external force causing separation of origin and insertion
what are physiological principles?
Using muscle force to move one region of the body to achieve movement of another bone or region
Post-isometric relaxation
**most common form of MET
-Muscle contraction-> increased tension in Golgi tendon organ->
inhibition of muscle contraction
Joint mobilization using muscle force
Restoration of motion to the articulation results in a gapping, or reseating of the distorted joint relations with reflex relaxation of the previously hypertonic musculature.
Joint mobilization using muscle force-Force of Contraction
Maximal muscle contraction that can be comfortably resisted by the physician (up to 30 to 50 lb of pressure depending on the joint treated)
Respiratory assistance
muscular forces involved in these techniques are generated by the simple act of breathing.
-The physician usually applies a fulcrum against which the respiratory forces can work.
Respiratory assistance-Force of Contraction
Exaggerated respiratory motion
Oculocephalogyric reflex
eyemovements reflexively affect the cervical and truncal musculature as the body attempts to follow the lead provided by eye motion
Oculocephalogyric reflex-Force of Contraction
Exceptionally gentle
Reciprocal inhibition
When a gentle contraction is initiated in the agonist muscle, there is a reflex relaxation of that muscle’s antagonistic group
Reciprocal inhibition-Force of Contraction
Think ounces,not pounds of pressure
when is Crossed extensor reflex used?
Used in the extremities where the muscle that requires treatment is in an area so severely injured (e.g., fractures or burns) that it is directly unmanipulable or inaccessible.
Crossed extensor reflex
When the flexor muscle in one extremity is contracted voluntarily, the flexor muscle in the contralateral extremity relaxes and the extensor contracts.
Crossed extensor reflex-forece of contraction
Think ounces, not pounds of pressure
what side does reciprocal inhibition act on?
Ipsilateral – Same side
