Mobile Universal Lexicon Evaluation System in MS: A New Visual Test of Rapid Picture Naming

Vision-based measures of rapid number naming (King-Devick [K-D]) have improved the sensitivity of sports-related concussion screening and also demonstrate slower testing times in patients with multiple sclerosis (MS). 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 MULES, a new vision-based test of rapid picture naming, to the visual assessment of patients with MS.
