Principles of Muscle Energy Flashcards
Contracture
fibrotic changes occur and muscle can’t be passively stretched
Isotonic contraction
muscle contraction is always constant
Isometric
change in tension with no change in origin or insertion
Isokinetic
contraction against resistance where angular motion is same.
Isolytic
eccentric contraction that breaks adhesions using an operator induced force to lengthen the muscle.
Ex. patient contracts muscle against resistance while physician applies force, or arm wrestle
True or False: Muscle energy is indirect
False: Muscle energy technique is ALWAYS direct, which is an osteopathic treatment in which the somatic dysfunction is moved directly through the restrictive barrier.
Post Isometric Relaxation
accomplish muscle relaxation; utilizes the principle of synaptic fatigue, meaning that after a sustained contraction.
Reciprocal Inhibition
lengthen muscle shortened by a cramp. When a gentle contraction is initiated in an agonist muscle, there is reflex relaxation of that muscle’s antagonistic group.
Joint Mobilization Using a Muscle Force
Restore joint motion in an articular dysfunction
Respiratory assistance
Goal: to improve body physiology using the patient’s forced respiratory motion
Oculocephalogyric Reflex
to affect reflex muscle contraction using eye movement
Crossed Extensor Reflex
Treat muscle dysfunction gently in the extremities where the muscle requiring treatment is not directly manipulatable (think cases of severe injury like a fracture or burn).This form of muscle energy technique uses cross pattern locomotion reflexes in our CNS. When a flexor muscle in one extremity is contracted voluntarily, the same muscle in the contralateral extremity relaxes and the extensor contracts.
Steps to Muscle Energy
- Position patient to feather edge of restrictive barrier
- Talk to patient and explain
- Have patient contract while physician uses counterforce for 3-5secs
- Both relax
- Repeat 3-5 times
- Reassess
