Q

How is the king devick test run?

A

pt reads numbers horizontally starting from the top left, each test card is harder by removing guidelines and making spacing tighter vertically

Q

T/F the king devic is bad for concussion screening

A

false, KD is a go to– need baseline before injury, then 5 sec slower than baseline is significant injury

Q

What are the infrared eye movement parameters?

A

fixations, regressions, duration of fixation, reading speed, reading comprehension

17
Q

What is the ReadAlyzer?

A

A streamlined design, USB connections, no power necessary, highly portable– have IR limbal tracker

18
Q

What does the raw data of eye movement tracking show?

A

shows yoked nature of movements, X is a blink, does not show comprehension level

19
Q

What is the short leftward line on an eye movement recording?

A

regression

20
Q

What is the long leftward line on an eye movement recording?

A

return sweep

21
Q

What is the vertical line on an eye movement recording?

A

fixation

22
Q

What is the horizontal line on an eye movement recording?

A

saccade

23
Q

What on an eye movement recording shows a less accomplished reader?

A

lots of regressions– (still yoked and tells nothing about comprehension)

24
Q

What does RightEye do?

A

tracks eye movements while reading and compiles data about stability, vertical and horizontal tracking and speed, etc
