Lecture 18: PNF

Question 1

Propioceptive

Answer 1

receiving stimulation with the tissues of the body

Question 2

Neuromuscular

Answer 2

pertaining to nerves and muscles

Question 3

Faciliation

Answer 3

making it easer

Question 4

Definition of PNF

Answer 4

an approach to therapeutic exercise that combines functionally based diagonal patterns of movement with techniques of neuromuscular facilitation to evoke a motor response and improve neuromuscular control and function

Question 5

Indications of PNF

Answer 5

• improve initiation of movement
• improve coordination of movement
• improve control of movement
• improve stability and mobility

Question 6

contraindications of PNF

Answer 6

• wound/post-operative site
• acute conditions/recent fx
• acture cardiopulm conditions
• joint traction with flaccidity
• spasticity that increases with reps

Question 7

general guidelines to PNF

Answer 7

• total movement patterns
• spiral or diagonal based patterns
• focus on major body parts: UE/LE, trunk, head/neck

*LE and head/neck often dont use PNF

Question 8

PNF patterns have __ dimensions

Answer 8

3

• flexion/extension
• abduction/adduction
• rotation

Question 9

PNF movement occurs in a ___ direction with ___ component

Answer 9

diagonal direction with rotatory component

Question 10

D1 flexion pattern

Answer 10

flexion, adduction, external rotation

Question 11

d1 extension pattern

Answer 11

extension, abduction, internal rotation

Question 12

d2 flexion

Answer 12

flexion, abduction, external rotation

Question 13

d2 extension pattern

Answer 13

extension, adduction, internal rotation

Question 14

D1 flexion picture

Answer 14

Question 15

D1 extension picture

Answer 15

Question 16

D2 flexion picture

Answer 16

Question 17

D2 extension picture

Answer 17

Question 18

D1 flexion is functional for

Answer 18

combing hair

Question 19

d1 extension pattern is functional for

Answer 19

reaching back for something

Question 20

PNF application essentials

Answer 20

• teach patterns start to finish
• mechanics and body position are essential
• begin pattern with distal component (fingers)
• appropriate pressure
• patient should look at limb
• use verbal cues
• rotation is pivotal

Question 21

therapist position for PNF

Answer 21

• visualize diagnoal line of movement

- watch body mechanics (stay in diagnol - GROOVE)

Question 22

Manual contact of therapist

Answer 22

• lumbrical grip used by therapist to control movement and resist rotation
• pressure comes from flexion at MCP joints
• therapist fingers conform to body part
• do not cause pain due to squeezing or putting too much pressure on the bony body parts

Question 23

communication and demands

Answer 23

• hand contact #1 form of communcation
• verbal commands very important
• vision theirs and yours

Question 24

techniques of faciliation

Answer 24

• slow reversal
• slow-reveral hold
• quick stretch
• repeated contractions
• hold relax
• contract relax
• otthers

Question 25

quick stretch

Answer 25

utilization of the stretch reflex to facilitate a muscular response

Question 26

slow-reversal

Answer 26

- isotonic contraction followed immediately by isotonic contraction of antagonist muscles - overflow from strong pattern to weaker pattern - purpose: increase strength and facilitate normal timing and coordination

Question 27

slow-reversal hold

Answer 27

- isometric hold performed at the end of an isotonic diagnol pattern - purpose: increase strength in a particularly weak or uncoordinated portion of range

Question 28

related contractions

Answer 28

- repeated concentric contractions (often initiated with quick stretches) - can be used at any point in the range of motion when more weakness is noted - principle of irradiation

Question 29

wrist finger flexion 1/5 - which PNF pattern would be best

Answer 29

D2 extension D1 flexion -both positions require wrist and fingers to be in flexion

Question 30

go-to technique for administering PNF

Answer 30

slow-reversal | quick stretch may come in handy if not initiating well at the beginning (may be probable for stroke patients)

Question 31

do not perform PNF on patients who have difficulty

Answer 31

following multi-level commands
