PNF - alternating isometrics, dynamic reversals & other techniques Flashcards
1
Q
alternating isometrics
A
- improve isometric strength and stability of postural muscles of the trunk or proximal stabilizing muscles of the shoulder girdle and/or core
2
Q
technique of alternating isometrics
A
manual resistance is applied in a single plane on one side of a body segment and then the other
3
Q
should motion occur with alternating isometrics
A
no
4
Q
is alternating isometrics done in WB or non-WB
A
both
5
Q
dynamic reversals
A
- agonist –> antagonist contractions eliciting bidirectional movement from patient
- resistance through the pattern
6
Q
technique of dynamic reversals
A
- elicit contraction and movement of the muscle you desire to recruit first
- when pt has almost completed first movement, switch hand placement and ask the patient to move in the opposite direction
7
Q
indications of dynamic reversals
A
- improve coordination specifically for those pt’s who demonstrate co-contractions
- modified to work through ROM
- improve strength and coordination
- improve muscle endurance due to continuous nature
8
Q
fast/quick stretch
A
- provide a quick stretch of the agonist when changing directions
- produces a relatively short-lived contraction of the agonist muscle and short-lived inhibition of the antagonist muscle which = contraction
9
Q
repeated contraction/stretch
A
- move through a pattern pausing and applying a quick stretch, press through more motion, pause, quick stretch, push
10
Q
what does repeated contraction/ stretch emphasize
A
strengthening in specific ranges throughout the motion
11
Q
dynamic reversal hold
A
same as dynamic reversals but with an isometric hold at end of the motion PRIOR to changing directions
12
Q
agonist reversal
A
- reversing the type of contraction you are giving, working concentrically, isometrically and eccentrically
- same side of joint always
