16
Q

Barthel index - scores range from

A

0 to 100

Higher score = greater independence

17
Q

Barthel index - common interpretation

A

Over 80 = ind and should be able to return home

less than 40 = very dependent

18
Q

Barthel index - common interpretation of score for outcome

A

95 - excellent outcome

75 - poor outcome

19
Q

Barthel index - valid prognositc tool following stroke for predicting what

A

recovery, level of care needed, and duration of rehab needed after stroke

20
Q

Barthel index - strengths

A

Interobserver reliability

21
Q

Barthel index - limitations

A

Does not reflect burden of communication and cognitive deficits
Lacks a result to represent stroke mortality
Responsiveness to change - floor and ceiling effects!

22
Q

Barthel index - best suited for who

A

stroke survivors requiring inpatient rehab

23
Q

Barthel index - considered a measure of

A

basic ADLs (self care and mobility)

24
Q

Modified Rankin Scale (mRS) - how many points

A

6 point

0 to 5

25
Q

Modified rankin scale - what type of scale

A

ordinal, hierarchical scale

26
Q

Modified rankin scale describes what

A

global disability with a focus on mobility

27
Q

Modified rankin scale - most commonly used functional measure in what

A

stroke trials

AND the primary or coprimary outcome in large scale stroke trials

28
Q

Modified rankin scale - used to measure

A

premorbid ability to assist in selection of patients and as a final outcome measure (for stroke trials)
Used for global disability

29
Q

Strengths of modified rankin scale

A

5 min to complete

30
Q

Modified rankin scale - score of 6

A

denotes death

31
Q

Modified rankin scale - limitations

A

reliability - potential for substantial interobserver variability

32
Q

Modified rankin scale - clinically relevant change

A

Less responsive to change than some scales but a single point change on mRS will always be clinically relevant

33
Q

QOL measure - short form 36

A

Geriatric scale that assesses 8 domains of health

Validated for stroke pts, noncompletion bias and floor/ceiling effects

34
Q

QOL measure - EuroQOL

A

Self completed questionairre
Assess 5 domains with visual analog scale
Validated for use in stroke populations
Noncompletion bias present

35
Q

QOL measure - Stroke specific QOL scale

A

Developed based on interviews with stroke survivors
Validated for use in stroke pts
Values for minimal detectable change and clinical important differences are established
