Q

A diagnostic test with high _ will have few false positives and a positive test will rule in the condition

a. sensitivity
b. specificity
c. likelihood ratio
d. none of the above

A

specificity

Q

Sensitivity- proportion of patients (with/without) the condition who have a (positive/negative) test result

A

with

positive

Q

Specificity- proportion of patients (with/without) the condition who have a (positive/negative) test result

A

without

negative

Q

Sensitivity- tests with high specificity have few false (positives/negatives) –> therefore, a (positive/negative) result (rules out/rules in) the condition

A

negative
negative
rule out

Q

Specificity- tests with high specificity have few false (positives/negatives) –> therefore, a (positive/negative) result (rules out/rules in) the condition

A

positive
positive

Q

Which of the following is the best statistic for evaluating the usefulness of a diagnostic test?

a. thresholds
b. sensitivity
c. specificity
d. likelihood ratios

A

likelihood ratios

Q

A patient presents with a disproportionate, non-mechanical, unpredictable pattern of pain provocation in response to multiple aggravating and easing factors, what type of pain is this classified as?

a. central sensitization
b. peripheral neuropathic pain
c. nociceptive pain

A

central sensitization

Q

A patient presents with disproportionate pain and a strong association with poor self-efficacy, what type of pain would you classify this as?

a. central sensitization
b. peripheral neuropathic pain
c. nociceptive pain

A

central sensitization

Q

A patient presents with diffuse areas of pain, tenderness on palpation, and non-specific aggravating/easing factors, what type of pain should this be classified as?

a. central sensitization
b. peripheral neuropathic pain
c. nociceptive pain

A

central sensitization

A patient presents with pain referred in a dermatomal distribution and a history of nerve injury, what type of pain would this be classified under? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

peripheral neuropathic pain

A patient presents with a history of nerve pathology or potential mechanical compromise and pain are provoked with movement tests that load the neural tissue, what type of pain can this be classified as? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

peripheral neuropathic pain

A patient comes to your clinic with symptoms of cutaneous distribution and pain with compression of neural tissue, what type of pain can this be classified as? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

peripheral neuropathic pain

What is the strongest predictor of peripheral neuropathic pain? a. history of nerve injury b. pain with loading neural tissue c. symptoms with movement testing that compresses neural tissue d. pain referred in a dermatomal or cutaneous distribution

pain referred in a dermatomal or cutaneous distribution

What is the strongest predictor of central sensitization pain? a. strong psychosocial factors (negative emotions, poor self-efficacy) b. pain or tenderness on palpation c. disproportionate and unpredictable pattern of pain provocation in response to non-specific aggs/eas factors d. pain disproportionate to the nature of the injury

disproportionate and unpredictable pattern of pain provocation in response to non-specific aggs/eas factors

A patient presents with a clear proportionate anatomical nature to aggravating and easing factors and pain is localized, what type of pain would you consider this? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

nociceptive pain

A patient presents with localized pain, intermittent and sharp pain with movement provocation, what type of pain would you classify this as? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

nociceptive pain

A patient is showing with a constant dull ache or throb at rest and does not have night pain or disturbed sleep, what type of pain should you classify this as? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

nociceptive pain

A patient shows with localized pain that is a sharp pain with movement and a dull ache at rest, what type of pain would you consider this? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

nociceptive pain

A patient presents to you with localized throbbing pain at rest, no pain at night and an absence of any burning or shooting pain, what would you classify their pain as? a. central sensitization b. peripheral neuropathic pain c. nociceptive pain

nociceptive pain

Nociceptive pain is the absence of which of the following? a. heaviness, night pain and a dull ache at rest b. disturbed sleep, antalgic movement patterns and a constant ache at rest c. pain in association with other dysesthesias, night pain or disturbed sleep, antalgic postures and pain described as burning, shooting, or sharp d. pain in association with other dysesthesias, pain described as electric-shock-like and clear proporotoniate easing factors

pain in association with other dysesthesias (crawling, electrical, heaviness) night pain/disturbed sleep antalgic (pain relieving) postures/movement patterns pain variously described as burning, shooting, sharp or electric-shock-like

What is the strongest predictor of nociceptive pain? a. clear proportionate mechancial/anatomical nature to aggravating and easing factors b. pain localized to the area of injury/dysfunction c. sharp pain with movement provocation d. night pain or disturbed sleep

pain localized to the area of injury/dysfunction
