exam Flashcards
explain chronic pain
pain that has gone past the normal tissue healing time of 3 mos; has no protective purpose; no more inflammation
differentiate chronic and nociceptive pain and its relation to sensitization
chronic pain = central bc the issue usually lies with the CNS sensitivity to activity; central sensitization is usually triggered by mechanical stimuli but not thermal; nociceptive pain = peripheral sensitization so nerves around area of pain are sensitized, protective in nature ; usually triggered by both mechanical and thermal stimuli
PQRST nociceptive
provoking & quality & severity: stimuli proportional to pain increase (e.g., light touch = sensitive; pressing = painful); NSAIDs and analgesics work
region: localized to area of injury; surrounding areas may be a lil sensitive
time: sensitive esp when area is inflamed; but inflammation goes away soon enough (acute; sub-acute)
assessment procedures and purpose
central sensitization index (CSI)
tampa scale of kinesiophobia
pain catastrophizing scale
painDETECT - neuropathic vs CS
quantitative sensory testing
CSI
quality of pain; higher score = higher likelihood of CS
0-29 sub
30-39 mild
40-49 moderate (Nijs framework)
50-59 severe
60-100 extreme
TSK
4 8 12 16 (+) used for checking (17px) consistency of px. response
higher = more kinesiophobia
37pts
PCS
30/52 clinically significant (13px)
rumination - 8, 9, 10, 11
magnification 6, 7, 13
helplessness
allodynia vs hyperalgesia
allodynia = pain when not pain
hyperalgesia = pain when pain
principles of altering pain memories (cognitive-targeted exercise therapy)
time contingent exercises
goal setting
addressing feared movements
motor imagery
make use of stress
address perceptions
painDETECT
0-12 neuropathic
12-19 not sure
19-38 CS
brain areas and parts that affect pain experience
homunculus - little man (directory of motor neurons)
- pain cant be localized bc homuncular smudging occurs
amygdala - fear and negative emotion
- certain movements have negative emotions and experiences
brodmann area 312
- sensory information and experience can be transmitted to area 4 (motor)
A-beta fiber - touch
A-gamma fiber - ms contraction (pressure, stretch)
C fiber - pain, temp, itch
gate control theory and CS
dorsal horn wind-up
disinhibition of interneurons (aka interneurons that are supposed to be inhibiting the pain dont work like they should) usually prevent overflow of 2nd order neuron
PSFS
functional scale (0-5)
SALIENCE
lower score less function
management principles
relax, exercise, self-regulate
parts of skin
epidermis (culugo sa batok)
dermis (papillary, reticular)
hypodermis (fat layer)
sensory receptors and levels, fx.
meissners (p d) - discrimination
Krause (p d) - cold
Ruffini’s (p d) - warmth
Pacinian (r d) - pressure, vibration [Pacinian = Pressure]
Merkel’s (epi) - superficial sensation
