EXAM 3: 3.21 PNF

Question 1

PNF

Answer 1

Proprioceptive
Neuromuscular
Facilitation

Question 2

Where did the idea for PNF begin? What was it based on?

Answer 2

neuro pts

• proximal muscles tend to irradiate into distal musculature
• muscles fire in certain movement patterns

Question 3

Why is it important to know that muscles fire in certain movement patterns? (impact on rehab)

Answer 3

• If we teach pts those patterns, get summated irradiation

- get overflow into muscles that aren’t firing well

Question 4

PNF and stroke/neuro pts

Answer 4

works - somehow gets their system to wake up

Question 5

Benefit to using PNF with ortho pts

Answer 5

• can wear them out with just a few reps
• can change resistance with every rep
• adds value to what you do by putting hands on them

Question 6

What are the essential components of PNF? (10)

Answer 6

1. manual contact
2. body position/body mechanics
3. stretch
4. manual resistance
5. irradiation
6. joint facilitation
7. timing of movement
8. patterns of movement
9. visual cues
10. verbal input

Question 7

PNF components: manual contact

Answer 7

• typically use lumbrical grip (no fingernails)
• go right to where you need to go without searching around
• where your hands are indicate which muscle needs to contract (hand on quad, quad contracts)

Question 8

PNF components: body position/body mechanics

Answer 8

• typically on a plinth or mat justified toward therapist (on edge)
• therapist in proper position (able to weight shift)

Question 9

PNF components: stretch

Answer 9

• quick stretch of a muscle facilitates contraction

Question 10

PNF: stretch with neuro/stroke/TBI pt benefit

Answer 10

quick stretch of muscle to be contracted will give an additional signal to contract

Question 11

PNF components: manual resistance

Answer 11

• almost always start PROM

- doesn’t take much to overcome and wear out certain muscles

Question 12

PNF: Why use PROM first?

Answer 12

• see available range
• motor learning - person has no idea what you want them to do with their limb
• gives you the ability to see that everything is in the right position

Question 13

PNF components: irradiation

Answer 13

• can’t take a flaccid limb and make it contract
• as we continue to do patterns, we hope other muscles that aren’t working will begin to fire
• Don’t want to give too much resistance, need to build up irradiation

Question 14

PNF components: joint facilitation

Answer 14

• stretch out joint capsule a little, relaxes the muscles that attach
• pushing the joint together to approximate, muscles tighten (cocontraction)

Question 15

PNF: joint approximation

Answer 15

• body thinks WB is happening

- resulting cocontraction creates stability at joint

Question 16

PNF components: timing of movement

Answer 16

“dance” between you and the pt

Question 17

PNF components: patterns of movement

Answer 17

D1
D2

• flexion/ext of UE
• flexion/ext of LE

Question 18

PNF components: visual cues

Answer 18

• pt needs to be looking at what they’re doing

- being able to see their hand gives them extra feedback

Question 19

PNF components: verbal input

Answer 19

time out verbal cues so you don’t confuse the pt

Question 20

diagonals

Answer 20

These are the movements that create the most irradiation

Question 21

D1

Answer 21

starts outside the body and come across

Question 22

D2

Answer 22

starts in and goes out

Question 23

UE D1 flexion

Answer 23

start: hand pronated, elbow extended
end: up and across (wrist toward face, fingers flex)

Question 24

UE D1 extension

Answer 24

opposite of D1 flexion

Question 25

D2 flexion

Answer 25

pulling out a sword

Question 26

D2 extension

Answer 26

put the sword back in
