PNF from the book

Question 1

agonist reversals (AR)
description
indications (2)

Answer 1

agonist reversals: concentric thru range followed by eccentric thru range

indications:
1. weak postural muscles
2. inability to eccentrically control body during movement transitions

Question 2

approximation
description
indications

Answer 2

approximation = joint compression

indications:
1. facilitate postural EXTENSORS

Question 3

repeated contractions (RC)
description
indications (4)

Answer 3

repeated contractions (RC): repeated isotonic contractions induced by quick stretch; thru the range or at the point of weakness

indications:

1. weakness
2. incoordination
3. muscle imbalances
4. lack of endurance

Question 4

rhythmic initiation (RI)
description
indications (5)

Answer 4

rhythmic initiation (RI): PROM, AAROM, resisted AROM

indications: *think neuro
1. spasticity
2. rigidity
3. hypertonicity
4. inability to initiate movement (apraxia)
5. motor learning deficits

Question 5

rhythmic stabilization (RS)
description
indications (6)

Answer 5

rhythmic stabilization (RS); co-contractions of agonist and antagonist

indications

1. instability in WBing
2. poor antigravity control
3. weakness
4. ataxia
5. painful muscle splinting
6. limited ROM caused by muscle tightness

Question 6

slow reversals (SR)/ slow reversal hold
description
indications (4)

Answer 6

slow reversals (SR); alternating contractions of agonist, then antagonist
SRH; add isometric hold at end

indications:

1. inability to reverse directions
2. muscle weakness or imbalance
3. incoordination
4. lack of endurance

Question 7

traction
description
indications

Answer 7

traction = separation of joint surfaces

indications: facilitates flexors
