Pain Models Flashcards
Levels of the pain model.
- Tissue damage and Nociception
- Perception
- Appraisal
- Pain Behavior
Is nociception synonymous with pain?
NO!
Example of nociception without pain.
Local anesthesia
Most common pain disorder in dentistry.
Myofascial pain
An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.
Pain
Subtypes of pain:
1) Actual tissue damage
2) Potential tissue damage
3) A description (in some patient report) involving reference to tissue damage.
Unpleasant abnormal sense of touch.
Dysesthesia
Is pain a psychological or physical state?
Psychological
Activity induced in the nociceptor and nociceptive pathways by a noxious stimulus is not what?
pain
An unpleasant experience that comes from actual or potential damage.
Pain
Tissue injury that stimulates pain receptors causes this kind of pain.
Nociceptive
Damage to the nervous system causes this kind of pain
Neuropathic.
T/F: As stimulus temperature increases, so does pain sensation intensity.
True
Increased sensitivity to pain.
Hyperalgesia
Example of hyperalgesia.
Slapping a sunburn
Pain from something that doesn’t normally cause pain.
Allodynia
Example of allodynia.
Clothing on sunburned skin.
Increased sensitivity to stimulation.
Hyperesthesia
Example of hyperesthesia.
Increased sensitivity to wind blowing on sunburned skin.
Altered sensation
Dysesthesia
Allodynia and Hyperalgesia are involved with this kind of pain.
Neuropathic.
Increased response to a repeated stimulus.
Sensitization
Acute pain is inflammatory, Nociceptive, or Functional?
Inflammatory
Chronic pain can be ________ or ________.
Nociceptive; Neuropathic; Inflammatory, or Functional
Pain Models
Cartesian
Clinical
Transmission system-based
Pain processing-based
Biomedical pain model
Pain is always a sign of tissue damage.
Pain and tissue damage have a linear relationship.
Psychiatric pain model
Pain without pathology is psychogenic
Biobehavioral pain model
Pain is a combination of physical and psychogenic elements.
It’s multidimensional and you can’t separate the different components of pain.
Specific pain receptors transmit pain to a “pain center” in the brain to cause the perception of pain.
Specificity Theory
Problems with the Specificity Theory
There’s pain without identifiable injury.
Injury without pain.
Injury and pain are disproportionate.
Temporal lag between injury and pain.
Non-specific effects of treatment.
Complex qualitative character of pain.
