acute <12wks after injury
chronic >12wks
3

recover in acute phase (<12wks)
- typically in 2 wks
4

IV - neck c/o and fx/dislocation
5
Q
what education should be provided to pts w acute WAD

return to prior level of activity as soon as possible
minimize cervical collar use
will return to normal
- reassure that recovery expected w/i first 2-3mo

- coordination
9
Q
how can you assess joint position error
A
w laser on head
3ft from target
close eyes, rotate head and try to return to same spot on target w eyes closed
3 trials
10
Q
what is a significant result when assessing joint position error and what does this indicate
A
> 4.5deg error
associated w dizziness and cervical joint position error
11
Q
how can you use the test to train joint position error and what is an important consideration
A
use the laser and change parameters:
- direction
- diagonals
- starting position
- gravity influence
- UE mvmt (internal perturbation)
*always give them target for external cues
12
Q
allodynia vs hyperalgesia
A
allodynia
- nonpainful stim is painful
hyperalgesia
- normal noxious stim is heightened
13
Q
how do you dx central sensitization and nociplastic pain
A
not a specific test to assess
use clinical hx and findings
14
Q

inc pain w a hot or cold stim earlier than normal
15
Q
what test can indicate hyperalgesia

mechanical stim (ie pin)
16
Q
what test can indicate allodynia
A
dynamic mechanical stim (ie soft)
17
Q
describes pain processing in someone w chronic pain and how is this relevant to PT
A
high pain tolerance but low pain threshold
- takes less to inc pain
in PT, we impact pain threshold
18
Q
what is one approach to treating someone w central sensitization and nociplastic pain
A
pain science approach
- conceptual approach to explain pain to pt accurate words to help them understand their hyper responsive nervous system
19
Q
what is the tissue tolerance point
A
point where tissue breaks
20
Q
what is protect by pain (PBP)
A
pain threshold
certain amt of input before tissue tolerance that body perceives pain
21
Q
how does injury impact the protect by pain line
A
after injury, body has a new PBP line that is wayyyy lower and therefore any little input creates pain
22
Q
how can a PT exercise program use a pain science approach
A
graded exposure
- building intensity, duration, and resistance over time
-> keeping below flare up line
23
Q
how can graded exposure be implemented into an exercise program
A
global - walking, bike, elliptical
semi-local - UE and trunk
local - DNF/DNE
24
Q
global vs local vs semi-local exercise
A
global - total body, inc HR
- if hig sweat barrier, release of endogenous opioids
local - anything done w neck
- specific to area
- might not tolerate right away
semi-local - things close to impaired part (ie UE, trunk)
- not specifically related to neck, but close enough for input to neck
25
why are psychological factors important to consider with pain science
all contribute to sensory input, heightened alarm system
26
what is an important strategy when creating a POC
make a problem list (MAPS)
Movement
Activity
Positions
Situations.... that are most painful
27
what is the concern with using traction in a chronic or flared up state
be painful d/t too much input w altered sensation input
28

local input may be too much
- maybe to upper back first (get carryover input to neck)
29
what are the 3 first interventions to start with for someone w a lot of pain

STM - local vs semi-local
exercise
- maybe more global

- persistent Ca2+ influx causing vasoconstriction and dec blood supply
- Na/K pump works to restore neuronal membrane potential which inc demand for ATP
- inc ATP demand triggers inc in glucose metabolism
- inc demand for glucose in setting of reduced blood supply creates a supply & demand disparity
