Mobile Universal Lexicon Evaluation System (MULES): A New Rapid Sideline Picture Naming Test for Concussion

Vision-based measures of rapid number naming (King-Devick [K-D]) have improved the sensitivity of sports-related concussion screening. K-D requires saccades and vergence, measuring aspects of frontal, parietal and brainstem centers. We developed the Mobile Universal Lexicon Evaluation System (MULES) to capture a more extensive vision network, integrating saccades, color perception, and object identification. This study introduces the MULES, a new vision-based test of rapid picture naming, in a cohort of youth and collegiate athletes at pre-season concussion testing.
