Objective Postural sway has been identified as a valid marker for assessing the presence of a concussion and monitoring return to activity progression. Instrumented balance assessments have shown to be more reliable in detecting postural sway. The purpose of this study was to determine if the C3Logix application can measure postural sway with the same degree of accuracy as the VSR Sport by NeuroCom.

Design Reliability.

Setting Athletic Training Lab.

Participants Forty-five Division I Lacrosse players, consisting of 27 males (Age = 20.07 ± 1.18 years) and 18 females (Age = 19.67 ± 1.29 years) from one University participated.

Outcome Measures Participants completed the Stability Evaluation Test (SET) on the VSR Sport while simultaneously completing the same balance assessment via the C3Logix application. The balance assessment consisted of three stances (double leg, single-leg, tandem stance) on two surfaces (firm & foam) for a total of six trials.

Main Results A Pearson correlation was computed to assess the reliability of balance data collected from the C3Logix application to that collected via the VSR Sport force plate. With the exception of one trial, single-leg on a foam surface (r = 0.66), all trials exceeded the preset r ≥ 0.70 threshold.

Conclusions Strong correlations between balance measurement values suggest the C3Logix application is a reliable alternative to a force plate when assessing postural control. The C3Logix application can offer healthcare providers a reliable method to collect instrumented balance data at a reasonable price point when compared to a force plate.
