Chronic pain and CRPS questions andanswers
pain - correct answer--"Unpleasant sensory and emotional experience associated with actual
or potential tissue damage"
•It is always a personal experience that is influenced to varying degrees by biological,
psychological, and social factors.
•Pain and nociception are different phenomena. Pain cannot be inferred solely from activity
in sensory neurons.
•Through life experiences, individuals learn the concept of pain.
•A person's report of an experience as pain should be respected.
•Although pain usually serves an adaptive role, it may have adverse effects on function and
social and psychological well-being.
•Verbal description is only one of several behaviors to express pain; inability to communicate
does not negate the possibility that a human or a nonhuman animal experiences pain.
pain prevalence - correct answer-◦18-20% in general adult population in developed countries
Nociceptors - correct answer-detect stimulus in PNS > SC > thalamus > sensory cortex >
integrates with other areas > output as pain
taxonomy of pain - correct answer--nociceptive: somatic and visceral
-neuropathic: peripheral and central
-idiopathic
somatic nociceptive pain - correct answer-clear issue or problem
visceral pain - correct answer-involves organs
-percussive pain for kidneys

After exercise.
central sensitization - correct answer-dorsal horn neurons become hypersensitive to pain in
response to high levels of nociceptive input causing secondary hyperalgesia; very common
post-stroke and post SCI; they are getting a warning sign too early or before anything has
happened.
peripheral sensitization - correct answer-hypersensitivity of injured tissue
spontaneous pain - correct answer-independent of stimulus
