Objective: This study sought to investigate correlations between OptoGait motion analysis technology and two commonly utilized concussion assessment instruments, the Balance Evaluation Scoring System and the ImPACT computerized neurocognitive assessment software, to see if OptoGait might be a valid concussion assessment tool.
Methods: Twenty Division 1 college women varsity soccer players completed trials of eight different conditions of the OptoGait test battery. Then participants completed the BESS and ImPACT tests. One hundred twenty eight total spatio-temporal variables were recorded for each trial of OptoGait. Pearson’s r correlations among these variables and BESS and ImPACT results were calculated and pattern analysis was completed to evaluate for emergent patterns in the data.
Results: Two patterns emerged. First, correlations for the eight OptoGait mean-score subtests were related to the Balance Double-Leg Foam Test (BESS). Correlations for the eight OptoGait mean-score subtests were related to the Balance Double-Leg Foam Test (BESS), and correlations between OptoGait standard deviation measures and the Balance Tandem Hard Surface Test (BESS) both indicated potentially significant patterns. No consistent patterns of correlation existed between the OptoGait variables and the ImPact results.
Conclusion: OptoGait conditions correlate at higher than predicted rates with subtests of the BESS instruments, but not the Impact measures.
