Baseline Near Point of Convergence and Concussion Test Scores in a Cohort of Athletes

Sports-related concussions can impair many brain functions, including vision, cognition, and memory. Concussion has also been associated with an abnormal near point of convergence (NPC). The SCAT-3 (Sport Concussion Assessment Tool, 3rd edition) and MULES (Mobile Universal Lexicon Evaluation System), a picture-based rapid automatized naming (RAN) test, are effective in detecting sports-related concussions. However, less is known about the role of the SUN (Staggered Uneven Number) test, a number-based RAN test, and NPC in concussion diagnosis as well as the relationship between concussion tests and NPC. Our aim was to establish baseline NPC and concussion test scores for collegiate and professional athletes and to compare these test values with each other.
