Balcer and her colleagues conducted a meta - analysis review of 15 previously - completed studies where
a rapid number naming test was utilized.
For
the rapid number naming test, athletes are given a baseline test before the season starts where they are asked to read numbers as quickly as they can off a series of three reading cards while being timed with a stopwatch.
It not only measures the speed of
rapid number naming, thus capturing impairment of saccadic eye movements, but the test - taker's balance, attention, language and visual recognition skills.
The King - Devick (K - D) test measuring the speed of
rapid number naming is an accurate and reliable method for identifying athletes who should be removed from a game or practice for further evaluation, researchers at the University of Pennsylvania found.
