PNF techniques 2

Question 1

AI

Answer 1

alternating isometrics

Question 2

AI is an intermediate step to

Answer 2

rhythmic stabilization

Question 3

What is AI?

Answer 3

• resists isometric contraction

- immediately followed by isometric contraction of antagonist pattern

Question 4

What is AI used for?

Answer 4

balancing tone - often in trunk stabilization

Question 5

What is rhythmic stabilization?

Answer 5

think perturbations

Question 6

purpose of RS?

Answer 6

• cocontraction affects both sides of the joint

- maintained resistance facilitates stabilization

Question 7

When would RS be used?

Answer 7

• limited ROM due to splinting or pain

- usu for head, neck, trunk stability

Question 8

SR

Answer 8

slow reversal

Question 9

What is slow reversal?

Answer 9

think moving through D1/D2

• movement slow and rhythmic
• can use resistance but don’t have to

Question 10

SR inhibits

Answer 10

arousal via RAS

stimulates activation

Question 11

SRH

Answer 11

slow reversal hold

Question 12

SRH DEC

Answer 12

through decrement of range

Question 13

SRH INC

Answer 13

through increment of range

Question 14

application: SRH DEc

Answer 14

pt can’t stabilize (ataxic), builds up ability to stabilize

Question 15

application: SRH INC

Answer 15

pt doesn’t have control through full ROM

builds up ability to move through full ROM with control

Question 16

SRH application

Answer 16

develop endurance and strength within pattern of movement

Question 17

AR

Answer 17

agonistic reversal

Question 18

What is AR?

Answer 18

think bridge

concentric » isometric » eccentric » isometric

Question 19

When would AR be used?

Answer 19

weakness or spasticity prevents control of body through full range

Question 20

RP

Answer 20

resisted progression

Question 21

RP

Answer 21

resisted isotonic movement during locomotion

think crawling

Question 22

purpose of RP

Answer 22

resistance results in overflow

Question 23

RC

Answer 23

repeated contractions

Question 24

What is RC?

Answer 24

• isotonic AROM to point of weakness
• Isometric hold, then quick stretch
• isotonically move to new range
• repeat

Question 25

purpose of RC

Answer 25

muscle spindle facilitation and overflow

Question 26

When to use RC

Answer 26

pt has weakness in the whole pattern
