Outcome measures were obtained via smartphone (single\/dual-task gait speed, cadence, step length), mBESS (double\/single\/tandem errors), and tandem gait (single\/dual-task time). We calculated area under the curve (AUC) values for each measure that demonstrated a significant difference between groups independently, and calculated a comprehensive AUC value for all measures combined.\n                    <jats:italic>Main results<\/jats:italic>\n                    : The concussion group walked significantly slower (mean\u2009\u2009=\u2009\u20090.89\u2009\u2009\u00b1\u2009\u20090.15 versus 1.05\u2009\u2009\u00b1\u2009\u20090.15 m s\n                    <jats:sup>\u22121<\/jats:sup>\n                    ;\n                    <jats:italic>p<\/jats:italic>\n                    \u200a\u2009\u2009=\u2009\u20090.002) and with significantly fewer steps per minute (median\u2009\u2009=\u2009\u2009103 [interquartile range\u2009\u2009=\u2009\u200994\u2013108] versus 116 [104\u2013118] steps\/minute;\n                    <jats:italic>p<\/jats:italic>\n                    \u200a\u2009\u2009=\u2009\u20090.002) than the control group under single-task conditions.

The AUC value for single-task gait velocity, single-task cadence, single-task tandem gait time, and dual-task tandem gait time indicated an excellent ability to distinguish between concussion and control groups (AUC\u2009\u2009=\u2009\u20090.91, 95% CI\u2009\u2009=\u2009\u20090.80\u20130.99).\n                    <jats:italic>Significance<\/jats:italic>\n                    : Smartphone-obtained gait measures and tandem gait times allowed for an excellent differentiation between adolescents with concussion versus control participants.
