5.3 - PNF Flashcards
Week 5, Wednesday
Describe the UE D1 Flexion / Ext pattern
D1 Flexion: Flex, add, ER
“Grab the earring” or “uppercut”
D1 Ext: Ext, abd, IR
“Throw the earring away”
Describe UE D2 Flexion / Ext pattern
D2 Flexion: Flex, abd, ER
“Pull the sword out of the sheath”
D2 Ext: Ext, add, IR
Describe LE D1 Flexion / Ext pattern
D1 Flexion: Flx, add, ER
“Kicking soccer ball”
D1 Ext: Ext, abd, IR
“Loading up to kick the soccer ball”
Describe LE D2 Flexion / Ext pattern
D2 Flexion: Flx, abd, IR
“Dog peeing on a bush”
D2 Ext: Ext, add, ER
What diagnoses is it common to use PNF with? Why?
Post-CVA
CP
Trying to get these patients out of the obligatory synergy patterns and/or abnormal reflexes
Describe the four levels / stages of motor control
a) Mobility
- Available ROM
b) Stability
- Ability to maintain a position or posture thru co-contraction around a joint
c) Controlled mobility
- Ability to move within and in and out of a WB position or rotating along a long axis
d) Skill
- Ability to perform a functional task
Describe slow reversals
What does this improve?
Resisted concentric contractions in both directions without rest
Increases stability, controlled mobility, and skill
Describe slow reversal HOLDs
What does this improve?
Slow reversals + isometric hold at each end of the movement
Increases stability, controlled mobility, and skill
Describe agonistics reversals
What does this improve?
Concentric contraction of the agonist, isometric hold, eccentric contraction against resistance (“therapist wins”)
Controlled mobility and skill
Describe contract-relax
What does this improve?
Stretch the intended muscle –> concentric contraction of involved muscle –> back into stretch position
Mobility / ROM
Describe hold-relax
What does this improve?
Stretch the intended muscle –> isometric hold at end-range –> relax –> increase stretch
Mobility / ROM
Describe hold-relax w/ agonist contraction (HRAC)
Same as hold-relax, but w/ active movement into the desired ROM
If the goal is to increase hip flexion, which muscle is the agonist? Antagonist?
Agonist = hip flexors
Antagonist = hamstring, hip extensors
Describe the UE Chop pattern
Leading arm performs D1 extension
Assisting arm performs D2 extension
Reverse chop = same patterns in flexion
What are the benefits of chops & lifts?
Promotes rotation & side bending
Moves an affected arm out of synergy
