What are the major principles of PNF?
Uses diagonal/spiral movement patterns
Manual contacts
Resistance
Short, concise verbal commands
Correct timing
Repetition
Proprioceptive stimulation
Uses stronger muscles to facilitate weaker muscles through overflow
What movement patterns characterize PNF?
Diagonal
Spiral
Combine:
Flexion/extension
Abduction/adduction
Rotation
⭐ NPTE clue: diagonal/spiral patterns → PNF
How does resistance differ for PNF stability vs mobility?
Stability goal → MORE resistance
Mobility goal → LESS resistance
What is overflow in PNF?
Activation of a weak/involved muscle through strong contraction of another muscle
Stronger muscles facilitate weaker muscles
What is chopping in PNF?
Bilateral UE asymmetrical pattern
Performed as a closed-chain activity
Used to improve:
Strength
Stability
Control
What is the developmental sequence used with PNF?
Progression of motor control through:
Mobility
Stability
Controlled mobility
