Q

What is nociceptive pain?

A

pain that arises from actual or threatened damage to non-neural tissue and is due to the activation of nociceptors

Q

What is nociplastic pain?

A

pain that arises from altered nociception despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain

Q

What are some symptoms of neuropathic pain?

A
  • burning, electric shock

Q

What are symptoms of nociplastic pain?

A
  • constant, even at rest
  • diffuse, widespread, generalized, poorly localized, non anatomic distribution
  • temporal summation, hyperalgesia
  • disproportionate to the nature of pathologic changes or injury, persists past healing

Q

What might you find during a physical exam of nociceptive pain?

A
  • reproducible on mechanical testing, clear, consistent
  • no remote tenderness or pain
  • no abnormal neuro findings
  • normal pain and detection thresholds
  • normal conditioned pain modulation and temporal summation

Q

What are physical exam techniques to be used for nociceptive pain?

A
  • orthopedic tests and measures
  • near tests and measures
  • function
  • pain level
17
Q

What might you find in a physical exam for neuropathic pain?

A
  • neuroanatomical pain distribution
  • sensory abnormalities in dermatomal pattern
  • motor findings in myotomal or peripheral nerve root distribution
  • abnormal pain thresholds
  • abnormal local detection thresholds
18
Q

What does a physical exam for neuropathic pain look like?

A

sensory t/m: dermatome/cutaneous

motor
- recruitment
- control
- endurance
- myotomes

reflexes

neurodynamic and nerve provocation testing

19
Q

What might you find during a physical exam for nociplastic pain?

A
  • inconsisitent, confusing, ambiguous response, findings
  • disproportionate, inconsistent nontechnical or non anatomical pain provocation
  • altered body perception
  • left right discrimination
  • diminished tactile acuity
20
Q

What does a physical exam look like for nociplastic pain?

A
  • graphesthesia (draw on area of pain)
  • left right discrimination testing
  • tactile acuity (2 point discrimination, stimulus localization)
  • mechanical detection thresholds testing
  • temperature pain thresholds testing
  • pain modulation testing
21
Q

What are the chances that someone has a psychological impact on their pain for nociceptive, neuropathic, or nociplastic pain?

A

nociceptive: minimal or absent

neuropathic: minimal

nociplastic: significant

22
Q

What are the goals of nociceptive pain treatment?

A
  • decrease perception of pain
  • improve function (ROM, control, strength)
23
Q

What are the goals of neuropathic pain treatment?

A
  • improve nerve health
  • improve neural transmission
  • creating healing environment: space, movement, blood flow
24
Q

What are the goals or nociplastic pain treatment?

A
  • cortical re-mapping
  • create a healing environment
