Clinical Performance Tests Flashcards
What is king devick used for?
reading saccades
How is the king devick test run?
pt reads numbers horizontally starting from the top left, each test card is harder by removing guidelines and making spacing tighter vertically
How many tests are in king devick?
3
T/F the statistical error is accounted for with king devic test
true
T/F the king devic is bad for concussion screening
false, KD is a go to– need baseline before injury, then 5 sec slower than baseline is significant injury
What is the developmental eye movement test?
DEM takes out horizontal saccades to assess rapid automatic naming
T/F you must finish DEM to get reliable results
true, cannot analyze an unfinished test
Which direction is a DEM test read?
vertically– takes out horizontal saccades
What is A+B on a DEM test?
total vertical time, language only
What is C on a DEM test?
the horizontal test, language and saccades
T/F the error is accounted for with DEM test
false, you have to use calculations to account for the error
How do you account for a language issue on a DEM test?
using a ratio of adjusted time
Which two mistakes require a time adjustment and which two do not?
adjust time: addition, omission
don’t adjust time: substitution, transposition
What is the Groffman visual tracing test?
pt follows the line pattern from letter to number with only their eyes, more points for a faster finish
How many points do you get on Groffman if you’re wrong?
0 points
What are the infrared eye movement parameters?
fixations, regressions, duration of fixation, reading speed, reading comprehension
What is the ReadAlyzer?
A streamlined design, USB connections, no power necessary, highly portable– have IR limbal tracker
What does the raw data of eye movement tracking show?
shows yoked nature of movements, X is a blink, does not show comprehension level
What is the short leftward line on an eye movement recording?
regression
What is the long leftward line on an eye movement recording?
return sweep
What is the vertical line on an eye movement recording?
fixation
What is the horizontal line on an eye movement recording?
saccade
What on an eye movement recording shows a less accomplished reader?
lots of regressions– (still yoked and tells nothing about comprehension)
What does RightEye do?
tracks eye movements while reading and compiles data about stability, vertical and horizontal tracking and speed, etc
