Question 6

PNF Stretching/Relaxation Technique Types

Answer 6

1. Hold Relax
2. Contract Relax
3. Contract-relax-anatagonist-contract

Question 7

Hold Relax

Answer 7

-autogenic inhibition
-tight agonist muscle is elongated voluntarily following isometric contraction hold
-PT moves into new range

Question 8

Contract Relax

Answer 8

-reciprocal inhibition
-tight agonist muscle elongated voluntarily following concentric isotonic contraction of antagonist
-PT moves into new range

Question 9

Hold-Relax-Anatgonist-Contract

Answer 9

-hold isometric contraction of agonist followed by relaxation of agonist
-followed by concentric contraction of antagonist
-pt moves into new range

Question 10

PNF Strengthening Technique Types

Answer 10

-Rhythmic Initiation
-Rhythmic Stabilization
-Repeated Contraction
-Slow Reversal
-Slow Reversal Hold

Question 11

Rhythmic Initiation

Answer 11

-for pt’s unable to initiate movement and limited in ROM bc increased tone
-used to teach pt movement patterns
-directed at agonist muscle

Passive mvmt. –> AAROM –> AROM w/ or w/o resistance

Question 12

Repeated Contraction

Answer 12

-for pt’s showing weakness at specific point or t/o entire ROM
-corrects imbalances within pattern by repeating weak portions of range
-directed at agonist muscle

repeated dynamic contractions of agonist concentrically against maximal resistance until fatigue

Question 13

Slow Reversal

Answer 13

-develops AROM and normal reciprocal timing of agonist and antagonistic muscles
-reversal of agonists

isotonic contraction of agonist followed immediately by isotonic contraction of antagonist muscle

Question 14

Slow Reversal Hold

Answer 14

-develops strength at specific point in AROM
-reversal of agonist

isotonic contraction of agonist followed immediately by isometric contraction at end of active range

Question 15

Rhythmic Stabilization

Answer 15

-promotes stability through co-contraction of proximal stabilizers of trunk, pelvis or shoulder girdle
-reversal of agonist
