摘　　要：Background:The tandem gait test has gained interest recently for assessment of concussion recovery.The purpose of our study was to determine the prognostic and diagnostic use of the single-and dual-task tandem gait test,alongside other clinical measures,within 10 days of pediatric concussion.Methods:We assessed 126 patients post-concussion(6.3§2.3 days post-injury,mean§SD)at a pediatric sports medicine clinic and compared them to 58 healthy controls(age:15.6§1.3 years;43%female).We also compared the 31 patients with concussion who developed persistent post-concussion symptoms(PPCS)(age=14.9§2.0 years;48%female)to the 81 patients with concussion who did not develop PPCS following the initial assessment(age:14.1§3.0 years;41%female).All subjects completed a test battery,and concussion patients were monitored until they experienced concussion-symptom resolution.The test battery included tandem gait(single-task,dual-task(performing tandem gait while concurrently completing a cognitive test)conditions),modified Balance Error Scoring System(mBESS),and concussion symptom assessment(Health and Behavior Inventory).We defined PPCS as symptom resolution time>28 days post-concussion for the concussion group.Measurement outcomes included tandem gait time(single-and dual-task),dual-task cognitive accuracy,mBESS errors(single/double/tandem stances),and symptom severity.Results:The concussion group completed the single-task(mean difference=9.1 s,95%confidential interval(95%CI):6.1-12.1)and dual-task(mean difference=12.7 s,95%CI:8.716.8)tandem gait test more slowly than the control group.Compared to those who recovered within 28 days of concussion,the PPCS group had slower dual-task tandem gait test times(mean difference=7.9 s,95%CI:2.0-13.9),made more tandem-stance mBESS errors(mean difference=1.3 errors,95%CI:0.2-2.3),and reported more severe symptoms(mean difference=26.6 Health and Behavior Inventory rating,95%CI:21.1-32.6).Conclusion:Worse dual-task tandem gait test time and mBESS tandem stance performance predicted PPCS
