Pain Perspectives
The father of the biomedical model with a linear mechanistic view of pain.
Who is Descarte? (Cartesian view)
Mild to extreme pain in an area of the body that is absent/amputated.
What is phantom limb pain
Increased pain from a stimulus that normally provokes pain.
Hyperalgesia
Pain that does not appear to have a reason mechanistically/pathologically.
What is nociplastic pain?
A nerve fiber that has lower myelination and is generally thought of as resulting in slow, dull, achey pain experience.
What is C-fiber(s)?
Developed the "Gate control theory" of pain.
Pain due to a stimulus that normally does not provoke pain.
What is Allodynia?
Increased responsiveness and reduced threshold of nociceptive neurons in the periphery to thestimulation of their receptive fields.
What is peripheral sensitization?
An injury or issue with the nervous system tissue.
What is neuropathic/genic pain?
A nerve fiber(s) that is thought to result in quick, sharp pain experience.
What is A-delta fibers?
George Engel developed this model in response to the overysimplified and reductionist biomedical model.
What is the biopsychosocial model?
Pain is felt in a different location that where the issue or nociceptive driver is.
What is referred pain?
Increased responsiveness of nociceptive neurons in the central nervous system to their normal orsubthreshold afferent input.
What is secondary hyperalgesia?
An issue with the tissue.
What is nociceptive pain?
The persistent strengthening of synapses based on recent patterns of activity. The more a neural pathway is used, the easier it is to activate it again.
What is long-term potentiation? (Neuroplasticity broader but ok answer).
The idea of the brain and neural signatures associated with pain, that our actions have theses distinct neurosignatures that are influenced by the overall central nervous system that are driven by our genetics, learning, past experiences.
What is the neuromatrix theory?
A high threshold sensory nerve cell that send news of danger or damage to the dorsal horn.
What is a nociceptor?
An unpleasant abnormal sensation, whether spontaneous or provoked
What is dysethesia?
This type of pain results from pathology or dysfunction of the peripheral or central nervous system, such as peripheral neuropathy.
A specific type of neuron that contributes to the nervous system becoming "wound-up" and is in a constant state of high reactivity, contributing greatly to chronic pain.
What is wide dynamic range neuron.
An injury or issue with the nervous system tissue.
What is neuropathic/genic pain?
Pain or increased sensitivity that occurs in non-damaged tissue often after an injury in the close proximity.
What is secondary hyperalgesia?
This type of pain would be caused by a bee sting or a cut.
What is nociceptive pain?
An unpleasant sensory and emotional experience associated with, actual or potential tissue damage.
