PNF Flashcards
What are the 4 types of PNF techniques?
Mobility
Stability
Controlled Mobility
Skill
Which technique has unidirectional agonist pattern?
rhythmic initiation
What is the purpose of rhythmic initiation?
increase ability to initiate movement, teach the movement, crossing the midline
Which technique involves slow rhythmic concentric contractions of agonist without relaxation between reversals?
slow reversal
What is the purpose of slow reversal?
increase motion of agonist; develop ability to reverse direction; strengthen agonist and antagonist
What are the 4 proprioceptive input considerations when performing PNF techniques?
Manual Contacts, Stretch, Maximal resistance, traction, Approximation
How do you perform an Agonist Reversal PNF pattern?
The patient concentrically resists with the agonist muscle through a PNF pattern and then ECCENTRICALLY resists the movement with the AGONIST in the opposite direction. Cue to resist eccentrically is “I’m going to push your arm down but resist me slowly and smoothly.”
What is an Alternating isometric PNF pattern?
An isometric contraction of the agonist then antagonist without allowing relaxation between contractions
What is the purpose of an alternating isometric pattern?
Used as a precursor to Rhythmic stabilization. Used for stability of a joint
What is rhythmic stabilization?
Simultaneous isometric contractions of agonist and antagonist patterns, in alternating directions resulting in co-contraction. Pt is asked to hold while therapist performs a gradual counter-rotational force.
What is a Slow Reversal Hold?
An isometric hold is added to the slow reversal technique at end range of the desired movement.
For STABILITY
What is a shortened held resisted contraction (SHRC)?
Not traditionally a PNF technique but this is when resistance is applied to an isometric contraction of muscles holding in a shortened position.
What is the purpose of SHRC?
increases stability in weight-bearing and holding due to weakness
What is the purpose of agonist reversals?
Improve control of part through full range of a lengthening contraction
What is the purpose of rhythmic stabilization?
co-contraction in various ranges for stability
