1

What is pain

An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage

2

What are the dualities of pain

Physiological experience and psychological experience

3

What are the goals of pain treatment (3)

1. Resolve the underlying pathology causing pain
2. Modify the patient's perception of pain
3. Allow the patient to maximize their functional abilities

4

What are the categories of pain (4)

1. Nociceptive
2. Neuropathic
3. Psychogenic
4. Carcinogenic

5

What is the function of pain (3)

1. Warning for withdrawal
2. Alerts that something is wrong
3. Protective function

6

What are the 2 types of nociceptive pain

1. Somatic
2. Visceral

7

What is somatic pain

Activation of nociceptors found in most body tissue

8

What is visceral pain

Activation of nociceptors found in viscera

9

Is visceral pain referred or localized

Referred

10

Is all of the viscera sensitive to pain

Nope

11

What are the types of neuropathic pain (2)

1. Peripheral
2. Central

12

What is psychogenic pain

Pain that originates from nonorganic sources and is associated with emotional, cognitive, and behavioral responses

13

What are the 4 types of pain

1. Acute
2. Chronic
3. Referred
4. Radicular

14

What is carcinogenic pain

Pain caused by cancerous pathology that is severe

15

What is acute pain

Combination of unpleasant sensory, perceptual, and emotional experiences that occur in response to noxious stimulus

16

Characteristics of acute pain (3)

1. Time limited
2. Persists as long as noxious stimulus persists
3. Serve a protective function

17

What is treatment of acute pain from musculoskeletal injury aimed to (3)

1. Facilitate resolution of underlying problem
2. Reduce inflammation
3. Modify the transmission of pain from periphery to CNS

18

What is chronic pain

Continuous long term pain of more the 12 weeks after healing would have occurred

19

What causes chronic pain (2)

1. Changes in sympathetic NS, adrenal activity, reduced production of endogenous opioids, or sensitization of primary afferents
2. Increased sensitivity to noxious and non-noxious stimuli`

20

What is referred pain

Pain felt at a location distant from its source

21

What is radicular pain

Pain originating from an irritated nerve root that follows a dermatomal pattern

22

What are pain receptors called

Nociceptors

23

What are the 4 types of sensors

1. Mechano
2. Thermo
3. Noci
4. Proprio

24

What are the 2 categories of peripheral sensory receptors

Superficial and deep

25

What are the types of mechanoreceptors (4)

1. Meissner's corpuscles
2. Pacinian corpuscles
3. Merkle cells

26

What are the 2 types of thermoreceptors

Cold and hot

27

What are the 3 types of proprioceptors

1. GTO
2. Pacinian corpuscles
3. Ruffini endings

28

What do meissner's corpuscles sense

Pressure and touch

29

What do pacinian corpuscles, merkle cells, and ruffini endings sense

Skin stretch and pressure

30

What do GTO sense

Change in muscle length and spindle tension
