Options for Evaluating and Tracking Pediatric Concussion
Background: It is estimated that 45 million persons between the ages of 5 and 19 years participate in some form of athletic activity. It is further estimated that 5%...
Research Abstract Category: Concussions
In situ use of the King-Devick Eye Tracking test and changes seen with sport-related concussion: saccadic and blinks counts
Objective: Sport-related concussion (SRC) can result in impaired oculomotor function. Oculomotor performance, measured utilizing the King-Devick/Eye Tracking test (K-D/ET), is reported to be able to identify sub-optimal brain function....
Concussion Evaluation and Management: An Osteopathic Perspective
Background: Concussions have been increasingly reported over the past decade, but the reported incidence likely minimizes the actual numbers of people affected. Associated symptoms include emotional, somatic, and cognitive...
The Effect of Linguistic Background on Rapid Number Naming: Implications for Native Versus Non-Native English Speakers on Sideline-Focused Concussion Assessments
Objective: To determine if native English speakers (NES) perform differently compared to non-native English speakers (NNES) on a sideline-focused rapid number naming task. A secondary aim was to characterize...
What sideline tests help diagnose concussion in athletes?
In patients suspected of having a concussion after a nontrivial head injury, the presence of headache alone has a sensitivity of 0.76 to 1.0 and a specificity of 0.83...
‘Sandbagging’ a Vision Test for Concussion-based Sideline Assessment: An Eye Movement Investigation Objectively Reveals the ‘Gamers’ Strategies
Objective: Quantitative eye movement characterization during ‘sandbagging’ of the rapid number naming King Devick (K-D) test. Background: Athletes may under-report concussion symptoms, leading to inappropriate return-to-play and increased risk...
Relation of Quantitative Eye Movements with Cognitive Dysfunction in Patients with Concussion
Objective: To assess the relation of quantitative eye movements with cognitive dysfunction in concussion. Background: Inter-saccadic interval (ISI) prolongation during rapid number naming on King-Devick (K-D) testing has been...
Correlating the King-Devick Test with Vestibular/Ocular Motor Screening in Adolescent Patients with Concussion: A Pilot Study
Background: The King-Devick (K-D) test is a rapid number-naming task that has been well validated as a sensitive sideline performance measure for concussion detection. Patients with concussion take significantly...
The King–Devick test is a valid and reliable tool for assessing sport-related concussion in Australian football: A prospective cohort study
Objectives Sport-related concussion (SRC) research has focused on impaired oculomotor function. The King–Devick (K–D) test measures oculomotor performance and is reported to identify suboptimal brain function. The use of...
Reported concussion incidence in youth community Rugby Union and parental assessment of post head injury cognitive recovery using the King-Devick test
Aim: To assess the frequency of reported head injuries in youth community Rugby Union and determine whether the King-Devick (K-D) test could be used by parents as a means...
Reliability of the King-Devick Test as a Baseline Concussion Test for Professional Football Players
Objective: To evaluate the reliability of the King-Devick (K-D) Test in a sample of professional football players across three consecutive seasons. Methods: Team personnel tested players (n=135) with the...
King-Devick and SCAT Symptoms as a Predictor of Return to Play in Professional Canadian Football Players
Objective: To investigate variables that predict time loss following the diagnosis of sport related concussion (SRC) in Canadian Football Players. Background: Literature on the timeline to return-to-play (RTP) from...
Rapid Number Naming and Quantitative Eye Movements May Reflect Contact Sport Exposure in a Collegiate Ice Hockey Cohort
Background: The King-Devick (K-D) test of rapid number naming is a reliable visual performance measure that is a sensitive sideline indicator of concussion when time scores worsen (lengthen) from...
fNIRS Differentiates Cognitive Workload Between Concussed Adolescents and Healthy Controls
Introduction Concussion remains a clinical diagnosis based on subjective and non-specific symptoms with additional supporting assessments, such as neurocognitive testing and, more recently, physical examination findings. However, there are...
Sideline Concussion Assessment: The King-Devick Test in Canadian Professional Football
Reasons for Study Sideline assessment tools are an important component of concussion evaluations. To date there has been little data evaluating the clinical utility of these tests in professional...
