PNF

Question 1

flexion
extension
rotation
*towards or away from midline

T or F: you use verbal commons during PNF

Answer 4

T

Question 5

T or F: hand placement is important in PNF

Answer 5

T

resistance given for PNF is greater if the goal is ______ and less if the goal is _______

Answer 6

stability
mobility

Question 7

do you know your PNF pattersn from the intervention quizlet

Answer 7

duh

Question 8

developmental sequence for PNF

Answer 8

• mobility
• stability
• controlled mobility
• skill

Question 9

mobility

Answer 9

initiate movement through functional ROM

Question 10

stability

Answer 10

maintain a position/posture through co-contraction adn tonic holding around a joint
ex. maintian midline in unsupported sitting

Question 11

controlled mobility

Answer 11

ability to move within a weight bearing position or rotate around a long axis
ex. prone on elbows, weight shift in quadraped

Question 12

skill

Answer 12

ability to consistently perform functional task and manipulate the environment with normal posture reflex mechanisms and balance reactions
ex. ADLs, community ambulation

Question 13

traction

Answer 13

elongation of a segment

Question 14

approximation

Answer 14

compression of a segment

Question 15

traction encourages _____ while approximation encourages _______

Answer 15

mobility
stability

Question 16

quick stretch

Answer 16

manually induced firing of muscle spindles

Question 17

chopping

Answer 17

combination of B UE asymmetrical patters performed as a closed
chain activity

Question 18

tapping

Answer 18

stimulus is applied over the muscle belly causing a quick stretch to the muscle spindle

Question 19

these 2 PNF techniques may be helpful for low tone

Answer 19

quick stretch and tapping

Question 20

normal timing principle

Answer 20

sequence of muscle contractions that result in coordinated movement and improved motor recruitment

Question 21

does prox control or distal control develop first

Answer 21

proximal

Question 22

T or F: distal to proximal timing is considered to be normal

Answer 22

T

Question 23

irradiation (overflow)

Answer 23

-indirect muscle recruitment
-incrs load on stronger body part –> incrs movement of weaker body part
ex: resisted LE flexion when rolling can lead to irradiation into trunk flexion

Question 24

agonistic reversal goal

Answer 24

controlled mobility, skill

Question 25

what are agonistic reversals

Answer 25

isometric contraction performed against resistance followed by alternating concentric/eccentric contractions w/ resistance ex: adding resistance with scap/pelvis patterns

Question 26

what is the goal of alternating isometrics

Answer 26

stability, strength

Question 27

what is the goal of rhythmic stabilization

Answer 27

mobility, stability

Question 28

rhythmic stabilization has a ______ component

Answer 28

rotational ex. pt is quadraped and you had resistance to R shoulder and L pelvis

Question 29

what is the goal with rhythmic initiation? what situation would you use them in

Answer 29

- mobility - to initiate movement when hypertonia exist

Question 30

T or F: movements with rhythmic initiation are fast

Answer 30

F: they are slow because you are trying to reduce hypertonia

Question 31

What is the goal with rhythmic rotation

Answer 31

mobility - good for hypertonia

Question 32

what is the goal of normal timing

Answer 32

skill

Question 33

normal timing is performed _____ to _____

Answer 33

distal to proximal

goal of timing for emphasis

Answer 34

skill, strength

Question 35

timing for emphasis uses ______ resistance

Answer 35

max

what is the goal of hold-relax active movement

Answer 38

mobility

Question 39

what is the goal of contract-relax and hold-relax

Answer 39

mobility

Question 40

what is hold-relax active movement used for?

Answer 40

improve initiation of movement in muscle groups 1/5 or less
