M1-2 Reading Guide 2

Question 1

Nociceptive pain: (acute/chronic)

Answer 1

acute

Question 2

Neuropathic pain: (acute/chronic)

Answer 2

chronic

Question 3

Nociceptive pain is a response to

Answer 3

noxious stimuli that are damaging or potentially damaging to tissue

• mechanical
• chemical

Question 4

How is nociceptive pain identified in an exam?

Answer 4

predictable response to stretch, compression, and movement

Question 5

Nociceptive pain is associated with these processes

Answer 5

• injuruy
• inflammation
• repair

Question 6

(Nociceptive/Neuropathic) pain can be both somatic or visceral

Answer 6

BOTH

Question 7

How is neuropathic pain different from nociceptive pain?

Answer 7

• persists past the point of healing

- appears to be associated with abnormal processing or sensitization within PNS and CNS

Question 8

What does peripheral neuropathic pain result from?

Answer 8

injury to neural tissue such as spinal or peripheral nerves

Question 9

sx of peripheral neuropathic pain

Answer 9

• burning

- paresthesia

Question 10

What are some of the sx of central neuropathic pain?

Answer 10

atypical sx

• widespread non-anatomical pattern
• poorly localized
• often unstable
• inconsistent responses to physical exam
• pain has a mind of its own

Question 11

True/False: All acute pain is peripherally mediated

Answer 11

False

Question 12

True/False: All chronic pain is centrally mediated

Answer 12

False

Question 13

What two mechanisms contribute to the development of chronic pain?

Answer 13

• nociceptive pain

- non-nociceptive pain

Question 14

How do nociceptive and non-nociceptive pain mechanisms affect the CNS and chronic pain?

Answer 14

• persuade the CNS that body tissue is in danger
• causes increased neuromatrix activity
• results in a lowered threshold for activation

Sensitization occurs

Question 15

What is mechanical pain?

Answer 15

• 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

Question 16

What is chemical pain?

Answer 16

result of chemical irritants in the tissue due to

• inflammation
• infection

Question 17

pattern: chemical pain

Answer 17

• usually constant
• may have a mechanical component that varies with aggravating and easing factors
• pain is still present at rest

Question 18

Pain that is constant and does not have a mechanical component- which means that it does not vary with aggravating and easing factors-suggests:

Answer 18

• acute disease

- serious pathology

Question 19

Neuropathic pain arises due to

Answer 19

central or peripheral sensitization

Question 20

How does neuropathic pain present (sx)?

Answer 20

widespread distribution of sx

• hyperalgesia
• allodynia
• inconsistent agg/ease factors
• s/s ANS disruption
• unpredictable or absent response to examination and physical therapy intervention

Question 21

What are the s/s of ANS disruption that may be seen with neuropathic pain?

Answer 21

• poor appetite
• depression
• anxiety

Question 22

Pain that persists beyond the time of normal healing is probably this type:

Answer 22

• neuropathic

- components of peripheral and central sensitization

Question 23

Chronic pain: is it all neuropathic?

Answer 23

NO
