  • Balance is a complex process that is a component of concussion evaluation and treatment. Purpose: To compare balance measures obtained from Sway Balance Test (SBT), a smartphone-based test, to common force plate measures and sternal position data, as well as to determine the reliability of the SBT. Methods: 24 college-aged participants completed two testing sessions. During each session participants completed three Sway Balance Tests while force plate and sternal position data were recorded. Participants also completed the Sensory Organization Test. Results: SBT overall scores were strongly inversely correlated with center of pressure elliptical sway area (r=-0.816, p<0.001), sway speed (r=-0.888, p<0.001), and sternal position marker elliptical sway area (r=-0.899, p=0.001). It was weakly correlated with the SOT (r=0.420, p=0.041). The SBT had a high test-retest reliability of 0.942. Conclusions: Our results indicate that the SBT is concurrently valid and reliable for measuring balance in healthy college aged individuals.
