Is risk of concussion in sports associated with risky or adverse health behaviors in students?

Is risk of concussion in sports or physical activity associated with risky or adverse health behaviors (e.g., substance use, self-harm, fights, etc.) in middle school and high school students? Student athletes who had engaged in risky or adverse health behaviors were more likely to have sustained a concussion, with middle school students at highest risk. The study identifies middle…

Dysfunction of the stress response in individuals with persistent post-concussion symptoms: a scoping review.

This study looks at the research on how the autonomic nervous system (also know as “fight-or-flight” and “rest-and-digest”) and the stress response change after a person experiences a concussion. The article reviewed several different tools that are in most clinical settings that can be used to measure changes in these systems. Article Citation: Farrell, G.,…

SNS Response to NINDS Statement on CTE

In late October 2022, the NIH National Institute of Neurological Disorders and Stroke (NINDS) updated their website and made the following statement: “Chronic traumatic encephalopathy (CTE) is a delayed neurodegenerative disorder that was initially identified in postmortem brains and, research-to-date suggests, is caused in part by repeated traumatic brain injuries” (italics added).   SNS recognizes…

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…
