PNF Flashcards
1
Q
Purpose of PNF
A
- Improves performance of functional tasks by increasing strength, coordination, flexibility, and ROM
- Primary goal is to help patients achieve optimal motor function and independence with ADLs
2
Q
Manual Contacts and Manual Resistance (facilitation component)
A
- Placing hands on skin stimulates pressure receptors and provides info to patient about desired motion
- Place your hand on the side of the direction you want the patient to go** (do not pull patient into direction you want them to go)
3
Q
Approximation (facilitation component)
A
- Taking long bone and pushing into joint
- Mechanoreceptors assist with this — load bone and mechanoreceptors cause muscles around that joint to contract
- Primary use for this is STROKE*
4
Q
Quick Stretch (facilitation component)
A
- Assists with stimulating muscle
- Apply rapid elongation of muscle which stimulates muscle contraction
- Muscle spindles protects the muscle (measures force and quickness of muscle stretch)
5
Q
UE PNF Patterns
A
- D1 flexion — grab the seatbelt
- D1 extension — buckle the seatbelt
- D2 flexion — shoot the track gun
- D2 extension — put gun back in holder
6
Q
LE PNF Patterns
A
- D1 flexion — “scottish man”
- D1 extension — “reverse scottish man”
- D2 flexion — “fire hydrant”
- D2 extension — “smooth criminal”

Q
Categories of PNF Techniques
A
- (1) Mobility — for flexibility and ROM
- (2) Stability — for strength, power, and postural stability
- (3) Controlled Mobility — for coordination
- (4) Skill
- above is the steps that a stroke patient would follow in order to recover
8
Q
Rhythmic Initiation & Rhythmic Rotation
A
- Sequential application of first passive motion, then active assistive, then active, then slight resistive motions
- Used to assist with task such as rolling
- Used to reduce tone, spasticity, and rigidity
- Often used with parkinsons patients
- This technique helps with MOBILITY*
9
Q
Slow Reversal
A
- Concentric contraction of muscles in agonist pattern is facilitated through manual contacts followed by switching hands to other side of limb to stimulate antagonist pattern
- This technique helps with MOBILITY and CONTROLLED MOBILITY*
10
Q
Slow Reversal HOLD
A
- Variation of slow reversal where a resisted isometric contraction is held at completion of range in each direction
- Used when transitioning from mobility to stability
- This technique helps with STABILITY**
11
Q
Rhythmic Stabilization
A
- Rotary resistive force applied around target joint to facilitate a co-contraction
- Patients goal is to hold static position against an isometric resistance
- Used to improve stability in unsupported sitting
- “do not let me move you”
- This technique helps with STABILITY**
12
Q
Alternating Isometrics
A
- Isometric contractions of agonist and antagonists are facilitated in an alternating fashion
- Often used with shoulder
- This technique helps with STABILITY**
13
Q
Agonistic Reversal
A
- Resistance to a concentric contraction followed by a stabilizing hold, resistance to an eccentric contraction, and another stabilizing hold
- This technique helps with STABILITY**
- Can also help with controlled mobility and skill but most likely used for stability
14
Q
Repeated Contractions
A
- Repeated quick stretches to an elongated muscle followed by an isotonic contraction in an agonist pattern
- Used for patients who lack strength and initiation of movement
- This technique is used for STABILITY**
15
Q
Timing for Emphasis (rarely used)
A
- Using strong muscles to help out weak muscles
- Isometric contraction of strong muscles while allowing only weak muscles to allow for joint motion, typically at a more proximal joint
- Used for STABILITY**
