Q

explain the specificity theory of pain. What are the 2 parts of the theory? how does it relate to the biomedical approach to pain?

A
  • degree of pain = degree of tissue damage…directly proportional
  1. upon injury, pain messages originate in nerves associated with damaged tissue and travel to the spinal cord
  2. signal is then sent to a motor nerve and the brain, where pain is perceived
  • biomedical approach to pain has a similar way of viewing pain
  • and also assumes a one-to-one correspondence to injury/disease
  • also overlooks psychosocial factors

Q

what is the biomedical approach to pain? what does it result in? what are the primary interventions used, and its limitations?

A
  • assumes a one-to-one correspondence to injury/idsease
  • results in unfortunate practices, such as patient-blaming, assuming psychiatric disorder, intentional faking of symptoms
  • focuses on pharmacological, surgical, or other medical interventions to control pain
  • limitations????

Q

what is the gate-control theory of pain? what does it include that was lacking in the specificity theory of pain?

A
  • neural pain gate in spinal cord opens or closes to modulate pain signals to the brain
  • involves inhibitor and projector neurons that respond to sensory input and send certain signals to the brain
  • includes physical, emotional, and cognitive factors that can open/close the gate
  • it includes an explanation for pain without a physical basis–is more holistic

Q

what is neuropathic pain? describe 4 conditions where this occurs. This provides counter-evidence for which theory?

A
  • pain without noxious stimulus, resulting from current/past disease/damage in peripheral nerves
  • counters the specificity theory
  1. neuralgia:
  • recurrent episodes of intense shooting or stabbing pain along a nerve
  • often follows infection
  1. causalgia:
  • recurrent episodes of severe burning pain that are often triggered by minor stimuli
  • AKA complex regional pain syndrome
  1. phantom pain syndrome
    - often experienced in an amputated limb
  2. neuropathy: damage to peripheral nerves

Q

what is the neuromatrix theory? this is an extension of which theory? what is a body-self neuromatrix?

A
  • extension of the gate-control theory
  • there is a widespread network of neurons distributed throughout the brain and spinal cord
  • this network is responsible for generating bodily sensations, including pain
  • various parts of the nervous system work together to respond to stimuli from the body and/or environment, and sensory input is just one type
  • body-self neuromatrix: widespread network of neurons that generates a pattern that is felt as a whole body possessing a sense of self

Q

what are 2 issues with self-reporting chronic pain and why?

A
  1. may not be taken seriously, since they have developed better coping mechanisms to deal with pain and only go to the doctor when the pain is really high
  2. chronic paid is different from acute or transient chronic pain because of how they try to adapt/cope over time

Q

compare organic vs psychogenic pain. what was the historical stance of these topics, compared to the contemporary stance?

A
  • organic: pain with a sensory, physical root
  • psychogenic pain: pain that results from psychological, non-sensory factors
  • historically, the two types of pain were conceptualized as separate entities
  • nowadays, scientists recognize that virtually all pain experiences involve an interplay of both physiological and psychological factors

Q

list 3 ways that emotions affect the pain experience

A
  1. negative emotions can exacerbate the pain response
  2. positive emotions reduce pain

Q

describe the bidirectional relationship of pain and stress. what is a piece of research evidence that supports this?

A
  • (1) Pain is stressful (partly due to lack of perceived control) and

Q

Q

name and describe the model that emphasizes the role of catastrophizing in managing distress in a social environment. what is the end result?

A
  • communal coping model of pain catastrophizing
  • expressing pain catastrophizing results in increased social support by caregivers, which reduces the effects of catastrophizing on pain
  • catastrophizing still has a negative effect overall, even with the benefit of social support

25
Q

name 4 different clinical (not psychological) interventions for pain. what is the best approach to treating chronic pain and why?

A
  • best approach to treating chronic pain is a mix between pharmacological and non-pharmacological approaches

29
Q

what is the relationship between sleep and pain?

Q

how might someone begin to enjoy pain?

A
  • classical conditioning
  • e.g., masochism
32
Q

what is the pattern theory of pain? how does it relate to the specificity theory of pain? what is the main issue with these theories?

A
  • receptors for pain are shared with other senses (e.g., touch)
  • no separate system for perceiving pain
  • people feel pain when certain patterns of neural activity occur (e.g., intense stimulation)
  • similar to the specificity theory theory of pain since both link tissue to pain directly
  • both don’t address the psychological factors involved in the pain exprience
33
Q

what are 2 common methods to induce pain in laboratory research?

A
  • cold-pressor task: have someone submerge their hand into cold water
  • muscle-ischemia procedure: reduces blood flow to the muscles of the arm to assess the individual’s pain threshold
34
Q

what are the 3 factors involved in the gate-control theory that adds nuance to the matter?

A
  1. the amount of activity in the pain fibres: the stronger the noxious stimulation, the more active the pain fibres
  2. the amount of activity in other peripheral fibres: activity here tends to close the gate
  3. messages that descend from the brain:
35
Q

what are 2 triggering conditions of pain reduction caused by placebos?

A
  1. expectancies: reduction of stress
  2. conditioning: trigger the release of endogenous opioids in the person’s bady

39
Q

what are 3 findings of testing patients with the Minnesota multiphasic personality inventory?

A
  • chronic pain sufferers show a profile with high scores on the neurotic triad: hypochondriasis, depression, hysteria
  • pattern holds regardless of whether it has a organic or psychogenic basis
  • for acute pain: moderately elevated scores in the neurotic triad scales, but these scores and those for the remaining MMPI scales are generally well within the normal range
40
Q

list 3 types of self-rating scales for pain

A
  1. visual analogue scale: rate pain by choosing a point on a line with labels only on the end
  2. numeric rating scale: 1-10, boxes

A
  1. affective (emotional-motivational)
  2. sensory
  3. evaluative
  • main limitation: it requires a fairly strong English vocabulary
42
Q

what is psychophysiology? what are 3 ways that this has been attempted to be measured?

A
  • *study of mental or emotional processes as reflected by changes they produce in physiological activity
  1. using an electromyograph to measure muscle tension
  2. measurements of autonomic activity (not very useful)
  3. electrical activity of the brain using an EEG

A
  • muscle tension is associated with various pain states
  • reflects pain intensity only when assessments are taken over an extended period of time
  • electomyograph

  1. reduct patient’s reliance on medication
  2. reduce disability that generally accompanies chronic pain conditions
49
Q

how can fear result in a worsening of health conditioning? use operant conditioning to explain this. what is this term called?

A
  • fear reduction
  • fear results in the avoidance of certain activities, which is negatively reinforced since they don’t experience their feared pain
  • this results in the fear persisting, and them engaging in less activity
50
Q

name and describe the 3 types of cognitive techniques used for active coping

A
  • distraction: focusing on something in the environment to distract oneself
  • nonpain imagery: creating a mental scene to distract oneself
