7.17 Association between first attempt buffalo concussion treadmill test and days to recovery in 855 children with sport related concussion: a historical cohort study and prognostic factors analysis

ObjectiveLittle is known about the prognostic value of the Buffalo Concussion Treadmill Test (BCTT) following the acute phase of sport-related concussion (SRC). We examined the added prognostic value of the BCTT performed 10 to 21 days after SRC in children, in addition to participant, injury and cl...

Description
Summary:ObjectiveLittle is known about the prognostic value of the Buffalo Concussion Treadmill Test (BCTT) following the acute phase of sport-related concussion (SRC). We examined the added prognostic value of the BCTT performed 10 to 21 days after SRC in children, in addition to participant, injury and clinical process characteristics on days to recovery.DesignHistorical clinical cohort study.SettingApproximately 150 Canadian multidisciplinary clinics.ParticipantsWe included 855 children (mean age 14 years, range 6–17 years, 44% female) who presented between January 2016, and April 2019.Interventions (or Assessment of Risk Factors)First attempt BCTT result, participant, injury, and clinical process characteristics.Outcome MeasuresDays from injury to recovery.Main ResultsHierarchal linear regression showed children who were exercise intolerant experienced an increase of 13 days to recovery (95%CI, 9 to 17). Each additional day between SRC and first BCTT was associated with a recovery delay of one day (95%CI, 1 to 2), and prior history of concussion was associated with a recovery delay of 3 days (95%CI, 1 to 5). Participant, injury, and clinical process characteristics, as well as the first attempt BCTT result explained 12% of the variation in recovery time, with 4% accounted for by the BCTT.ConclusionsExercise-intolerance assessed 10 to 21 days after SRC was associated with a recovery delay. However, this was not a strong prognostic factor for days to recovery.
