Muscle Energy Flashcards
Concentric
Muscle contraction that results in the two ends of a muscle approx
Isometric
Muscle contraction that results in increased tension without approximating the two ends of the muscle
Isotonic
Muscle contraction that results in no increased tension, but does result in approx of two ends of the muscle
Physiological barrier
Point to which a pt can actively move to a particular point
Anatomical barrier
Point to which a pt can passively move a particular joint
Post isometric relaxation
Muscle causing restriction is engaged and contracted
No movement allowed
Activation of golgi tendon organ
Reciprocal inhibition
Muscle antagonist to muscle causing the restriction are engaged and contracted
No movement permitted but reciprocal/antagonist muscles are contracted
Activation of reciprocal reflex arc in SC allow for reflex relaxation of agonist muscle
Golgi tendon organ
Fibers arranged in series
Measures actual tension on muscle
Response created by isometric muscle contraction
2 point palpation of vertebral positioning
Interspinous space alerts to flex/ext activation
Transverse process alerts to rotation
Both alerts to sidebending
Facet model
Flexion: facets open
Extension: facets close
Flexed dx: in extension, dysfunction side moves inferior
Extended dx: in flexion, dysfunction side does not move
Sacral dx
Deep sulcus and P/I ILA:
Same = unilateral flex/ext
Opposite = torsion
Flex: SFT and sulcus same side, axis named by +SFT
Ext: SFT and sulcus opposite, axis named by +SFT
Torsion: [ILA side] on [opposite +SFT]
Forward torsion: SFT and sulcus same side
Backward: SFT and sulcus opposite
L5 and sacrum
L5 side bent: sacral axis
L5 rotation: sacral rotation opposite
With flexion and extension sacrum and L5 do opposite
