Mobile Universal Lexicon Evaluation System (MULES) test: A new measure of rapid picture naming for concussion
چکیده انگلیسی


- A novel rapid picture naming test, the MULES, was assessed as a potential concussion screening tool.
- We piloted the MULES in a cohort of volunteers and compared it to the King-Devick test of rapid number naming.
- Both tests involve saccadic and other eye movements, which are affected in concussion.
- The MULES test may engage different and more extensive neural systems.
- In the future, the MULES test of rapid picture naming will be assessed on athletic event sidelines.

ObjectiveThis study introduces a rapid picture naming test, the Mobile Universal Lexicon Evaluation System (MULES), as a novel, vision-based performance measure for concussion screening. The MULES is a visual-verbal task that includes 54 original photographs of fruits, objects and animals. We piloted MULES in a cohort of volunteers to determine feasibility, ranges of picture naming responses, and the relation of MULES time scores to those of King-Devick (K-D), a rapid number naming test.MethodsA convenience sample (n = 20, age 34 ± 10) underwent MULES and K-D (spiral bound, iPad versions). Administration order was randomized; MULES tests were audio-recorded to provide objective data on temporal variability and ranges of picture naming responses.ResultsScores for the best of two trials for all tests were 40-50 s; average times required to name each MULES picture (0.72 ± 0.14 s) was greater than those needed for each K-D number ((spiral: 0.33 ± 0.05 s, iPad: 0.36 ± 0.06 s, 120 numbers), p < 0.0001, paired t-test). MULES scores showed the greatest degree of improvement between trials (9.4 ± 4.8 s, p < 0.0001 for trials 1 vs. 2), compared to K-D (spiral 1.5 ± 3.3 s, iPad 1.8 ± 3.4 s). Shorter MULES times demonstrated moderate and significant correlations with shorter iPad but not spiral K-D times (r = 0.49, p = 0.03).ConclusionThe MULES test is a rapid picture naming task that may engage more extensive neural systems than more commonly used rapid number naming tasks. Rapid picture naming may require additional processing devoted to color perception, object identification, and categorization. Both tests rely on initiation and sequencing of saccadic eye movements.

The Mobile Universal Lexicon Evaluation System (MULES) is a rapid picture naming test. It includes 54 color pictures of fruits and vegetables, animals, and other objects, which subjects must name as quickly as they can from left to right without making errors. The MULES requires rapid eye saccades and complex neural processing, and may be a useful screening tool for concussion.138
