Lecture 10 - Part 2 Flashcards
do catastrophizers or non-catastrophizers experience more pain -
=catastrophizers
what situations do people most do Pain Catastrophizing -
=700+ studies
Rheumatoid arthritis, osteoarthritis, fibromyalgia, sickle cell anemia, soft tissue injuries, neuropathic pain, dental patients, healthy populations
why is Pain Catastrophizing predictions necessary -
=One of the most important predictors of pain experience.
• Heightened levels of pain, pain behaviour
• Contributes to higher level of disability following surgery • Predicts increased consumption of analgesic medication • More prolonged hospitalization
what are the Pain Catastrophizing: Mechanisms -
=Endogenous Pain Modulation
Attentional Model
explain Endogenous Pain Modulation as a pain catastrophizing mechanism -
=direct impact on endogenous pain modulation mechanisms in the brain and spinal cord
• Compromised descending inhibition of pain
explain attentional model as a pain catastrophizing mechanism -
=• Heightened “chronic” activation
• Heightened sensitization -> chronic hyperalgesic state
how can pain catastrophizing be seen as a communal coping model -
=• An effort to garner social support from others
• Engaging in exaggerated pain expressions to solicit assistance or
emphatic responses
Double edged sword:
• Increases attention to pain • Reinforcement
what are the Economic Impact Associated with Pain -
=• $4 billion spent annually in Canada on over-the-counter pain medications.
• Chronic pain costs more than heart diseases, cancer, and HIV combined
• Direct health care costs > $6 billion/year
• Loss of productivity > $19 billion/year
what are the three categories of Common Pain Killers -
=Non-Narcotic Analgesics (Non-Opioids)
Local anesthetics, e.g., lidocaine
Opiods (morphine, codine, etc)
explain what is included in Non-Narcotic Analgesics (Non-Opioids) -
=NSAIDs (non-steroidal anti-inflammatory drugs) aspirin
ibuprofen (Advil, Motrin)
many others
Acetaminophen (Tylenol)
what is another approach to dealing with pain -
=sensory stimulation
virtual reality
psychological control
explain sensory stimulation -
=1. Transcutaneous electrical nerve stimulation (TENS) works mainly by stimulating A-beta fibers, closing pain gates
• Counter-irritation
2. Massage
3. Acupuncture
explain Virtual Reality -
=3-dimensional simulated environment.
Example
• Burn patients during wound care (U of Washington)
explain Psychological Control -
=Evidence for opioid enhancement
• Progressive Muscle Relaxation • Hypnosis
• Meditation
what are Comprehensive Pain Treatment Programs -
=Above techniques plus:
Behaviour/operant therapies
• reducing the overt display of pain, not the experience of
pain
• normalize behaviour, fear of movement, reinforcement
contingencies, possibly reduce pain by distraction
