FRT

Question 1

What does it measure?

Answer 1

Balance - by looking at max forward reach using a fixed BOS

Question 2

Can it track balance changes over time?

Answer 2

Yes

Question 3

Can it be used in modified environments?

Answer 3

Yes

Question 4

What populations is it good for?

Answer 4

Older adults
Repeat fallers
PD

Question 5

Test-retest reliability

Answer 5

0.89

Question 6

Inter-rater reliability

Answer 6

0.98

Question 7

Sensitivity (detecting falls - ruling in)

Answer 7

76%

Question 8

Specificity (identifying absence of falls)

Answer 8

34%

Question 9

PPV (test predicted compared to actual number of falls)

Answer 9

33%

Question 10

Accuracy (agreement between test and actual number of falls)

Answer 10

46%

Question 11

Is the FRT good at testing for the absence of falls?

Answer 11

No - specificity is poor (SPIN - can’t rule in that they won’t have a fall)

Question 12

If a patient demonstrates impairments, how likely is it that they will have a fall?

Answer 12

76% (sensitivity)

Question 13

20-40 (M)

Answer 13

16.73cm

Question 14

20-40 (W)

Answer 14

14.64cm

Question 15

41-69 (M)

Answer 15

14.98cm

Question 16

41-69 (W)

Answer 16

13.81cm

Question 17

70-87 (M)

Answer 17

10.47cm

Question 18

70-87 (W)

Answer 18

13.16cm

Question 19

Cutoff score predictive of falls

Answer 19

Less than or equal to 6cm

Question 20

MDC (acute stroke)

Answer 20

3.7cm

Question 21

Cutoff scores (acute stroke)

Answer 21

> 10cm: unlikely to fall
6-10cm: 2x more likely to fall
1-6cm: 4x more likely to fall
<7cm: most restricted in ADLs
