註釋Author's abstract: Context: The Balance Error Scoring System (BESS) is a commonly utilized and recommended sideline assessment tool to evaluate post-concussion postural stability. Baseline BESS scores are typically recorded during preseason physical examinations in the athletic training room or nearby laboratory. However, post-concussion assessment typically takes place on the sideline during a sporting event. Objective: The purpose of this study was to evaluate the effect of a sideline environment on BESS performance. Setting: 37 NCAA Division 1 healthy, female student athletes (SA) and 32 healthy, female non-athlete healthy young adult (HYA) controls were assessed on BESS performance in three different environments: a controlled laboratory or baseline (BL), a basketball arena (BKB) and a football field (FB). The SA group performed the experimental trials during a live competition while the HYA group was tested with minimal distractions. Interventions: The BESS was administered using an Airex Pad and videotaped from the frontal and sagittal planes. Main Outcome Measures: Two 2 x 3 ANOVAs with repeated measures, one 2 x 6 ANOVA with repeated measures, and a frequency distribution were used to analyze the results. Results: A significant main effect was found for the two groups (p = .001) with the SA group scoring higher than the HYA group. Significance within the SA group was found between BL and FB (p = .047) environments and FB and BKB (p = .005) environments. Significance within the HYA group was noted between BL and BKB trials (p = .025). Significance was found between groups for the single leg firm (p = .032), single leg foam (p
