M1-2 Reading Guide 2 Flashcards
Nociceptive pain: (acute/chronic)
acute
Neuropathic pain: (acute/chronic)
chronic
Nociceptive pain is a response to
noxious stimuli that are damaging or potentially damaging to tissue
- mechanical
- chemical
How is nociceptive pain identified in an exam?
predictable response to stretch, compression, and movement
Nociceptive pain is associated with these processes
- injuruy
- inflammation
- repair
(Nociceptive/Neuropathic) pain can be both somatic or visceral
BOTH
How is neuropathic pain different from nociceptive pain?
- persists past the point of healing
- appears to be associated with abnormal processing or sensitization within PNS and CNS
What does peripheral neuropathic pain result from?
injury to neural tissue such as spinal or peripheral nerves
sx of peripheral neuropathic pain
- burning
- paresthesia
What are some of the sx of central neuropathic pain?
atypical sx
- widespread non-anatomical pattern
- poorly localized
- often unstable
- inconsistent responses to physical exam
- pain has a mind of its own
True/False: All acute pain is peripherally mediated
False
True/False: All chronic pain is centrally mediated
False
What two mechanisms contribute to the development of chronic pain?
- nociceptive pain
- non-nociceptive pain
How do nociceptive and non-nociceptive pain mechanisms affect the CNS and chronic pain?
- persuade the CNS that body tissue is in danger
- causes increased neuromatrix activity
- results in a lowered threshold for activation
Sensitization occurs
What is mechanical pain?
- occurs as a result of sufficient compressive or tensile force on normal tissue
- usu has intermittent pattern with clear agg/ease factors
- predictable response to examination
What is chemical pain?
result of chemical irritants in the tissue due to
- inflammation
- infection
pattern: chemical pain
- usually constant
- may have a mechanical component that varies with aggravating and easing factors
- pain is still present at rest
Pain that is constant and does not have a mechanical component- which means that it does not vary with aggravating and easing factors-suggests:
- acute disease
- serious pathology
Neuropathic pain arises due to
central or peripheral sensitization
How does neuropathic pain present (sx)?
widespread distribution of sx
- hyperalgesia
- allodynia
- inconsistent agg/ease factors
- s/s ANS disruption
- unpredictable or absent response to examination and physical therapy intervention
What are the s/s of ANS disruption that may be seen with neuropathic pain?
- poor appetite
- depression
- anxiety
Pain that persists beyond the time of normal healing is probably this type:
- neuropathic
- components of peripheral and central sensitization
Chronic pain: is it all neuropathic?
NO
