VALIDATION OF A NEURO-FITNESS DEVICE TO ASSESS COGNITIVE MEASURES: A PILOT STUDY

Abstract

BACKGROUND A new portable neurocognitive training tool that administers central and peripheral visual and cognitive drills using a 7-foot-wide touchscreen light-board technology is being introduced into the sport and therapy fields. The purpose of this study is to assess the validity of the Reflexion Edge cognitive assessments compared to the FDA-cleared, ImPACT Computer-based test and Sway Medical App assessment. METHODS 22 healthy adults, 19-66 yrs, M = 23.54 + SD = 9.81, 54% male, have participated, however the target enrollment is 100 participants. Participants completed one each of Reflexion Edge assessment using a 7-ft by 3-ft touchscreen light-board, ImPACT test using a laptop, and Sway assessment using an iPhone. RESULTS Spearman’s Rho correlational analyses were administered to determine the relationship between the Reflexion Edge scales and the ImPACT computer-based and Sway Medical app scales. Findings showed Reflexion Edge scales demonstrated significant correlations with multiple ImPACT and Sway Choice Reaction Time & Speed Processing scales, r = + 0.448 to 0.660, p’s < 0.05; ImPACT Attention & Memory scales, r = + 0.425 to 0.813, p’s < 0.05; and Sway Executive Function scales, r = + 0.424 to 0.776, p’s < 0.05. All analysis were conducted at an α of 0.05. CONCLUSIONS Despite a lack of statistical power, the Reflexion Edge cognitive measures demonstrated significant associations with several of the ImPACT computer-based and the Sway Medical app cognitive assessment measures. In addition, the correlational effect size (+ 0.362 to + 0.421) of several of the other Reflexion Edge scales suggested promising associations with the ImPACT and Sway app scales. The continuation of this study to increase the N and determine significant relevance is supported. In conclusion, Reflexion Edge may serve as a viable cognitive assessment tool based on its comparable association with established ImPACT Computer-based and SWAY Medical app assessments.
