Muscle Energy and Articulatory Principles & LAB Flashcards
Define Muscle Energy technique
The patients muscles are actively used on request, from a precisely controlled position, in a specific direction, against a distinctly executed physician counterforce
Who came up with muscle energy?
Fred L. Mitchell, Sr., DO Almost didn’t become a thing
What is Eccentric contraction?
muscle tension allows the origin and insertion to separate, in effect to lengthen the muscle
What is concentric contraction?
contraction of a muscle resulting in the approximation of the origin and insertion , to shorten the muscle
What is a Isotonic contraction
: a concentric or eccentric contraction against a steady but yielding counterforce, allowing a constant tone (constant weight)
What is Isokinetic contraction
a concentric contraction in which the joint motion is at a constant rate/speed (weight can vary)
What is Isolytic contraction
a type of eccentric contraction in which the muscle’s concentric contraction is overpowered by a stronger counterforce (weight is greater than maximal effort) leading to a lengthening of the muscle
What is Isometric contraction
the distance between the origin and the insertion of the muscle is maintained at a constant length (neither eccentric nor concentric)
Post-isometric Relaxation Idea
Immediately after an isometric contraction the neuromuscular apparatus is in a refractory state during which passive stretching may be performed without encountering strong myotatic reflex opposition.
Force of contraction in isometric contraction
Sustained gentle pressure (10-20 lbs
Reciprocal inhibition MOA
When a gentle contraction is initiated in the agonist muscle, there is a reflexive relaxation of that muscle’s antagonistic group
Example: Cramping hamstring(agonist), contraction of quad(antagonist)
DONE WITH OUNCES OF COUNTER PRESSURE
Crossed Extensor Reflex MOA
This form of muscle energy technique uses the learned “cross pattern locomotion reflexes”(walking) in the central nervous system. When the flexor muscle in one extremity(left hamstring) is contracted voluntarily, the flexor muscle in the contralateral extremity(right hamstring) relaxes and the extensor(right quad) contracts.
Example: right hypertonic hamstring
OUNCES of pressure. DONE BECAUSE EFFETED LEG IS SO BADLY INJURED
Oculocephalogyric Reflex MOA
The eye movements reflexively affect the cervical and truncal musculature as the body attempts to follow the lead provided by eye motion
Respiratory Assistance MOA
Goal: Improve body physiology with the patient’s voluntary respiratory motions
The muscular forces involved in these techniques are generated by the simple act of breathing. This may involve the direct use of the respiratory muscles themselves, or motion transmitted to the spine, pelvis, and extremities in response to ventilation motions. The physician usually applies a fulcrum against which the respiratory forces can work.
Isolytic Lengthening MOA
It is postulated that the vibration used here has some effect on the myotatic units in addition to mechanical and circulatory effects [11].Example: Contracture of the bicep
