1
Q

pain is

A

cognitive recognition of noxious stimuli or injury

2
Q

general conceptualization of pain

A

as one somatosensory modality

3
Q

conceptualization of pain: 2 Classifications

A

“fast” & “slow” pain

4
Q

Fast pain is

A

~sharp, stabbing, knife-like sensation

~mediate temperature, and non-discriminative touch

5
Q

Fast pain is initially felt by

A

Ad fibers of the Neospinothalamic component of the pain pathways

6
Q

Importance of fast pain

A

~gives us the quick reflexes from segmental action and the ascending Localized discriminative nature of pain sensation

7
Q

Slow pain is

A

enduring, aching, intense pain

~associated with the affective & emotional nature of pain

8
Q

slow pain- mediated

A

~C-fibers

~Paleospinothalamic component of pain pathways and is

9
Q

Pain will tell the system that

A

Alerts the nervous system to danger

10
Q

Perception of pain is not just the _____ recognition but also..

A

cognitive recognition of nociceptive 1° afferent input but it is also a complex blending of various sensory modalities and the affective understanding of the sensory input

11
Q

pain: important role in

A

~preparing the body for response to injury including both somatic & autonomic responses
~modulate the pain with descending modulation of this input

12
Q

pain: strong Relationship

A

pain to affect & motivation

13
Q

Pain: Affect

A

Emotional feeling, tone, or mood attached to a thought elicited by conditions and circumstances of internal and external environments and nociceptive sensory input has a large impact on these emotional feelings

14
Q

Pain: Motivation

A

State of need within us that arouses, maintains, and directs behavior toward a goal
~nothing more motivating than pain

15
Q

divide pain into

A

acute and chronic pain

16
Q

Acute pain

A

~occurs as a result of tissue damage
~well-defined onset and duration
~proportional to the magnitude of the injury
~protective in nature

17
Q

Chronic pain

A

~no clear point of onset
~outlasts time expected for tissue healing
~occur with or without tissue damage – so NOT proportional to extent of damage and serves
~No protective function

18
Q

Pain Can be defined as ___ or ____

A

nociceptive or neuropathic pain

19
Q

Nociceptive pain

A

~Due to activation of peripheral receptors in response to tissue injury and inflammation

20
Q

Neuropathic (neurogenic) pain

A

~signals the presence of nervous system pathology in the absence of peripheral receptor activation – most commonly damage to peripheral nerves or the central nociceptive pathways
~

21
Q

common causes of neuropathic pain

A

~peripheral nerve pathologies – metabolic polyneuropathies or infectious mononeuropathies
~Thalamic syndrome- abnormal firing of thalamic neurons producing pain as perceived by the cerebral cortex

22
Q

treatment for nociceptive pain

A

~anti-inflammatories
~counter-irritants
~narcotics

23
Q

treatment for neuropathic pain

A

~Na+ channel blocking agents such as Gabapentin (NeurontinTM) & Pregabalin (LyricaTM), Carbamazepine &
~other anti-seizure medications and Lidocaine
~other local anesthetics
