Q

What is purpose of PNF?

A

these motions move in a spiral diagonal pattern of facilitation to provide for an optimal contraction

moving from lengthened to shorten position

Q

Why does this movement pattern make sense?

A

because a single muscle is not solely responsible for one movement so this mimics sport of function

Q

What is the optimal resistance?

A

apply just enough to have smooth controlled, pain free movement throughout the ROM, don’t hold breath

Q

What is timing for emphasis?

A

PT changes normal time of sequence to emphasize a place in the range

ex: greater resistance can be placed at end ranges

Q

What else is timing for emphasis good for?

A

maximum resistance can provide overflow or irradiation

goal is to increase response and stimulate action at a specific motion within a pattern

Q

What are two other ways to provide sensory feedback?

A
  1. traction
  2. approximation

both are directed at joint receptors, which assist joint position

Q

Why is the scapula so important?

A

because you need full control and motion but also need to generate force from it

What muscles are involved in posterior depression?
rhomboids, lats, lower trap
26
What are two types of D2 scap PNF patterns?
anterior depression, posterior elevation think of a throwing mechanism
27
Where should PT stand for D2 scap?
stand at pt head facing feet
28
What muscles are being used for D2 anterior depression?
SA, pecs
29
What are muscles are being used for D2 posterior elevation?
upper trap, levator scap
30
You need proximal _______ before distal _______?
stability, mobility
31
What are two UE PNF patterns?
d1, D2
32
What is the appropriate movement pattern for UE motions?
rotation should be first to be truly diaganol then flexion/extension then ABD/ADD and RD/UD or INV/EVE
33
What are components of D1 flexion?
Shoulder- Flex, Add, ER Forearm- sup wrist- radial flex fingers- flex
34
What are components of d1 extension?
Shoulder- Ext, Abd, IR Forearm- pron wrist- ulnar ext finger- ext
35
What are components of d2 flexion?
shoulder- flex, abd, ER Forearm- sup wrist- radial ext finger- ext
36
What are components of d2 extension?
shoulder- ext, add, IR forearm- pronation wrist- ulnar flexion finger- flex
37
What is a PNF technique used to teach a pattern?
rhythmic initiation begin with: 1. passive, active assisted, resisted
38
What are three PNF techniques to increase mobility?
1. contract relax/ hold relax 2. hold relax active contraction 3. agonist contraction
39
What is contract relax?
resisted sub max isometric contraction for 3-5 seconds followed by relaxation and movement into increased range (autogenic inhibition)
40
What is autogenic inhibition?
sudden relaxation of muscle after period of high tension, self induced
41
What is hold relax active contraction?
use hold relax technique for tight muscle, then follow it with a contraction of antagonist muscle
42
What is agonist contraction?
use principles of reciprocal inhibition, which is slow controlled contraction of opposite ms being stretched held 3-5 seconds and done 2-4 times
43
What are PNF techniques used to increase stability?
1. alternating isometrics 2. rhythmic stabilization 3. stabilizing reversals
44
What are alternating isometrics?
alternating isometric contraction of agonist and antagonist ms no motion is intended, resistance can be applied in one straight plane but no rotation
45
What is rhythmic stabilization?
isometric contraction of agonist and antagonist in all 3 planes to produce a co-contraction hands placed on opposite joint surfaces simultaneously
46
What are stabilizing reversals?
alternating isotonic contraction opposed by enough resistance to prevent motion with only small movement allowed used to isolate end or mid range
47
What are three PNF techniques to increase muscle strength and movement control?
1. dynamic reversals 2. timing for emphasis (repeated contractions) 3. Combination of isotonics
48
What is dynamic reversals?
active motion changing from one direction to the opposite without pause or relaxation
49
What is timing for emphasis?
repeated use of stretch reflex to initiate a muscular response or to reinforce and strengthen a pre existing contraction "quick stretch"
50
What is combination of isotonics?
- PT resist pt’s through desired range (concentric) - At end range, PT has pt hold (stabilization) - After stability, pt slowly moves back to start position (eccentric) Keep hands on pt (same position), no relaxation between phases
51
What are scap pivotors?
SA, traps
52
What are scap stabilizers?
Rhomboids
53
How can you progress scap exercises?
1. start in sidelying 2. prone on elbows 3. prone going from B UE to single UE 4. start WB on wall with shoulders at 90
54
What is LE D1 flexion?
hip- flex, Add, ER Ankle- DF/ INV toes- ext
55
What is LE D1 extension?
hip- ext, ABD, IR ankle- PF/ INV Toe- flex
56
What is LE D2 flexion?
hip- flex, abd, IR ankle- DF/ EVE toe- ext
57
What is LE D2 extension?
hip= ext, add, ER foot- PF/ INV toes- flex
58
What are D1 pelvic patterns?
anterior elevation and posterior depression key for weight acceptance/ efficient gait terminal stance/jumping/steps
59
What are D2 pelvic patterns?
good for eccentric control like step down terminal swing phase and loading/kick ball
60
How are pelvic patterns usually performed?
initially in sidelying with involved extremity towards ceiling can also be done in sitting, supine, quadriped and standing motion from trunk not legs
