Q

What is the sensitivity measurement?

A

TRUE POSITIVE

Sensitivity measures how often a test correctly generates a positive result for people who have the condition that’s being tested for.

A highly sensitive test will flag almost everyone who has the disease and not generate many false-negative results. (Example: a test with 90% sensitivity will correctly return a positive result for 90% of people who have the disease, but will return a negative result — a false-negative — for 10% of the people who have the disease and should have tested positive.)

Q

What does a SPECIFICITY measurement mean?

A

TRUE NEGATIVE RATE
Specificity measures a test’s ability to correctly generate a negative result for people who don’t have the condition that’s being tested for (also known as the “true negative” rate). A high-specificity test will correctly rule out almost everyone who doesn’t have the disease and won’t generate many false-positive results. (Example: a test with 90% specificity will correctly return a negative result for 90% of people who don’t have the disease, but will return a positive result — a false-positive — for 10% of the people who don’t have the disease and should have tested negative.)

Q

What is the main goal of subtyping concussive patients?

Q

What is the greatest risk to the concussed person?

A

The greatest risk to a concussed person is that they will be re-concussed or will suffer an injury because they are impaired attention.

Q

What is “Oriented times three” and what is it used for?

A

Oriented times three means that you are oriented to PERSON, PLACE and TIME.
Does the person know the name of the hospital, the date and the time?

It is a working memory test and not a true test of whether the patient can orient to current time and space.

Q

What is clinically significant change?

A

A clinically significant change is a change in client performance that (a) can be shown to result from treatment rather than from maturation or other uncontrolled factors, (b) can be shown to be real rather than random, and (c) can be shown to be important rather than trivial.

24
Q

What is PREVALENCE?

A

Prevalence

Prevalence = the number of cases of a disease in a specific population at a particular time point or over a specified period of time.

When we talk about prevalence, we can either refer to ‘point prevalence’ or ‘period prevalence’.

25
Q

What is INCIDENCE?

A

Incidence = the rate** **of new cases of a disease occurring in a specific population over a particular period of time.

Two types of incidence are commonly used: ‘incidence proportion’ and ‘incidence rate’.

26
Q

What are associated DATA for concussions beyond subtypes?

A

mechanism of injury

history of previous concussions

length of time since previous concussion

time to medical clearance

past medical history

27
Q

How do boxing concussion symptoms differ from football concussion Symptoms?

A

Boxers motor-related symptoms

Football mood and behavioral disturbances

28
Q

What are compensatory Strategies

A

develop memory books

shorter work sessions

frequent feedback

always review previous sessions to ensure retention

29
Q

Nexus

A

a series of connections linking two or more things

To tie together

30
Q

What is quantitative data?

A

Quantitative data is numbers-based, countable, or measurable. Quantitative data tells us how many, how much, or how often in calculations.

31
Q

What is DTI and what is it used for?

A

Diffuse Tensor Imaging

Can assess TBI

DTI is uniquely able to probe the microscopic structure and is well-suited for the assessment of Traumatic Axonal Injury (TAI)

32
Q

What are 4 measures of tissue water diffusion?

A

FA - Fractional Anisotropy - a summary measure derived from DTI describes the directional coherence of water diffusion in a tissue

MD - Mean Diffusivity

AD - Axial Diffusivity

RD - Radial Diffusivity

33
Q

What is Fractional Anisotropy?

A

FA - Fractional Anisotropy - a summary measure derived from DTI describes the directional coherence of water diffusion in a tissue

34
Q

What is coherence?

A

1 - the quality of being logical and consistent.

“This raises further questions on the coherence of state policy”

2 - the quality of forming a unified whole.

“the group began to lose coherence and the artists took separate directions”

35
Q

What is collinear?

A

lying on or passing through the same straight line

36
Q

Greatest value of DTI

A

examining relationship between DTI - integrity - and postconcussive symptoms

37
Q

What is opposite to empirical?

A

Empirical methods are objective, the results of a quantitative evaluation that produces a theory. Non-empirical methods are the opposite, using current events, personal observations, and subjectivity to draw conclusions

38
Q
A

the degree to which the accuracy of a test, model, or other construct can be demonstrated through experimentation and systematic observation (i.e., the accumulation of supporting research evidence) rather than theory alone.

39
Q
A

based on, concerned with, or verifiable by observation or experience rather than theory or pure logic.

“they provided considerable empirical evidence to support their argument”

40
Q

What is Qualitative data?

A

Qualitative data can help us to understand why, how, or what happened behind certain behaviors.

41
Q

What is value of HIGH test-retest reliability?

A

When you retake the test, if there is high test-retest reliability, then there is a real change.

42
Q

What is Test-retest reliability?

A

Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals.

The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for stability over time.

43
Q

Persistent?

A

continuing to exist or endure over a prolonged period

44
Q

What is MCI?

A

mild cognitive impairment

45
Q

What is physiological?

A

characteristic of the healthy or NORMAL FUNCTIONING OF THE BODY

46
Q

What is a neurological deficit?

A

A neurologic deficit refers to abnormal function of a body area.

This altered function is due to injury (or disease) of the brain, spinal cord, muscles, or nerves.

47
Q

What are examples of ALTERATION IN MENTAL STATE?

A

DISORIENTATION

CONFUSION

SLOWED THINKING

48
Q

What are ACEs?

A

adverse childhood events

49
Q

What is the somatosensory system

A

The somatosensory system is also known as the somatic senses, touch or tactile perception.

Anatomically speaking, the somatosensory system is a network of neurons that help humans recognize objects, discriminate textures, generate sensory-motor feedback and exchange social cues.

  1. Sensory neurons relay peripheral sensations such as pain, pressure, movement or temperature from the skin to the brain.
50
Q

What is Commotio cordis?

A

A rare condition that can occur when the chest wall is impacted during a narrow, vulnerable moment in the heartbeat cycle, which can knock the heart out of rhythm

synchronize

A
53

Means working together with others towards a common goal, typically by sharing ideas and resources.

55
Q

What is Paucity?

Paw city

A

refers to “littleness” in numbers (as in “a paucity of facts”) or quantity (“a paucity of common sense”). The word comes from paucus, Latin for “little.”
