A Mobile Device Dual-Task Paradigm for the Assessment of mTBI.

Research Objective: Dual-task performance, in which individuals complete two or more activities simultaneously, is impaired following mild traumatic brain injury. The aim of this project was to develop a dual-task paradigm that may be conducive to military utilization in evaluating cognitive-motor function in a standardized and scalable manner by leveraging mobile device technology.

Methods: Fifty healthy young adult civilians (18-24 years) completed four balance stances and a number discrimination task under single- and dual-task conditions.
