Early Postinjury Screen Time and Concussion Recovery

Objectives: To determine the association between early screen time (7-10 days postinjury) and postconcussion symptom severity in children and adolescents with concussion, as compared to those with orthopedic injury (OI). Methods: This was a planned secondary analysis of a prospective longitudinal cohort study. Participants were 633 children and adolescents with acute concussion and 334 with OI aged…

Characterizing Symptoms Before and Following Concussion in Professional Hockey

Do the types of symptoms matter in the acute evaluation period? Based on this study in professional hockey players by SNS members Jared Bruce & Ruben Echemendia and colleagues they do! Post injury cognitive, somatic/physical, and headache symptoms best differentiated concussed players and active controls. Pre-injury affective/emotional symptoms were also associated with increased likelihood of concussion among…

Psychological aspects of sport-related concussion: An evidence-based position paper

Sport-related concussions (SRC) have become a public health issue, however little research has focused on the the psychological aspects of this injury. This position paper identifies five postulates that are intended to stimulate research and practice on psychological aspects of SRC. Article Citation:Gordon A. Bloom , Alicia M. Trbovich , Jeffrey G. Caron & Anthony…

Test-Retest, Interrater Reliability, and Minimal Detectable Change of the Dynamic Exertion Test for Concussion

The Dynamic Exertion Test (EXiT) was developed to inform return-to-play (RTP) decision-making following clinical recovery from sport-related concussion (SRC). The current study established test-retest reliability in addition to minimal detectable change scores of an objective dynamic exercise assessment among healthy adolescent and adult athletes. The EXiT may be an objective approach to inform RTP decision-making…

Assessing the Assessments: Baseline Cognitive Evaluations

Two methods of baseline cognitive testing were evaluated in high school athletes. The authorsadministered the Immediate Post-Concussion Assessment and Testing (ImPACT), a commonly usedcomputerized concussion test, as well as more traditional paper and pencil neuropsychological measuresto a group of high school athletes. The study found that the ImPACT and paper and pencil tests measuredifferent aspects…

Early vs. Delayed Evaluation & Persisting Concussion Symptoms During Recovery In Adults

In this new article SNS members Stephen Bunt, Nyaz Didehbani, Ph.D. and C. Munro Cullum, Ph.D. found that a delayed presentation to a specialty concussion clinic (30 or more days post-injury) regardless of previous evaluation was associated with poorer recovery outcomes in adults compared to those with an earlier presentation. Time from injury to a formal…

Optimizing Order of Administration for Concussion Baseline Assessment Among NCAA Student-Athletes and Military Cadets

It’s that time of year – time to get ready for a new school year and a new sports season! Pre-season testing of symptoms, cognition, and balance often utilizes multiple tests to determine a “baseline” to which athletes’ performances can later be compared if they are suspected to sustain a concussion throughout the season. New research demonstrates the…
