Q

How is pain processed?

A
  1. noxious stimuli > 2. algogenic chemicals > 3. activate pain receptors (nocioceptors) > 4. nerve impulse gets sent to the brain

Q

What are the theories of pain?

A
  1. that it is mechanistic; this excludes psychological pain
  2. Ronald Melzak’s gate control theory: pain is a physiological mechanism mediated by psychological processes
    • ex. when an athlete gets an injury, but only feels pain once the game is over, we can say that the gate (i.e. the spinal cord) is closed due to the environment

Q

What three factors dictate the condition of the gate?

A
  1. the amount of activity in pain fibres
  2. the amount of pain in the periphery
  3. the messages descending from the brain

Q

What is the McGill pain questionnaire (exam question)?

A

Pain is rated on 20 independent categories from lowest to highest pain descriptions, and RATINGS ARE PERFORMED OVER TIME.

17
Q

.What are some strategies for pain management?

A
  1. chemical analgesia
  2. surgical approaches
  3. acupuncture
  4. electrical nerve stimulation
  5. hypnosis
  6. biofeedback
  7. relaxation techniques
  8. CBT
18
Q

How can hypnosis help with pain?

A

Because hypnotic analgesia can tackle pain from different modalities

19
Q

How is hypnotizability related to pain relief?

A

The higher hypnotizable you are, the more likely you will experience the analgesic effects of hypnosis

20
Q

What is stress inoculation?

A

A technique used to control pain (a CBT technique)

- decreases performance on other tasks

21
Q

How can hypnosis effectively treat pain caused by radiographic exams?

A

Because it reduces the memory of the pain, which reduces stress, which reduces pain

22
Q

Is pain bottom-up or top-down?

A

Pain is a bottom-up process influenced by a top-down procedure
- hypnosis tries to block the top-down procedure

23
Q

Can hypnosis block pain at the level of the spinal cord ?

A

Yes

24
Q

What processes are affected by sensory suggestions?

A

A sensory suggestion can affect both the sensory processes as well as the affective processes

25
Q

What processes are affected by affective suggestions?

A

They only influence affective processes

26
Q

How does the wording of a suggestion influence the pain process?

A

The wording of the suggestion influences which brain regions are activated

  • posterior occipital activation during hypnotic induction (because of suggestion to visualize)
  • brain activates at frontal region during suggestion
    • brain activation is bilateral
27
Q

What is naloxone?

A

It reduces placebo effects

28
Q

Are hypnotic effects the same thing as placebo?

A

No, placebo effects are reversible (hypnotic analgesia is not)

29
Q

What is hypno-sedation?

A

The use of hypnosis in conjunction with stress reducing medication

30
Q

What are some suggestions for analgesia?
