Baseline Neurocognitive Testing in Sports-Related Concussions: The Importance of a Prior Night’s Sleep
Authors: D. Jake McClure, Scott L. Zuckerman, Scott J. Kutscher, Andrew J. Gregory and Gary S. Solomon
The management of sports-related concussions (SRCs) utilizes serial neurocognitive assessments and selfreported symptom inventories to assess recovery and safety for return to play (RTP). Because postconcussive RTP goals include symptom resolution and a return to neurocognitive baseline levels, clinical decisions rest in part on understanding modifiers of this baseline. Several studies have reported age and sex to influence baseline neurocognitive performance, but few have assessed the potential effect of sleep. We chose to investigate the effect of reported sleep duration on baseline Immediate Post- Concussion Assessment and Cognitive Testing (ImPACT) performance and the number of patient-reported symptoms.
What are the most appropriate return-to-play guidelines for concussed child athletes?
Author: L Purcell
To examine concussion literature for specific guidelines regarding return to play (RTP) following sportrelated concussion in child athletes. To make recommendations regarding the most appropriate RTP guidelines for child athletes following sport-related concussion.
Factors associated with delayed recovery in athletes with concussion treated at a pediatric neurology concussion clinic
Authors: Suzanne Bock1 & Rod Grim1 & Todd F. Barron2,9 & Andrew Wagenheim3 & Yaowen Eliot Hu4,5,6 & Matthew Hendell2 & John Deitch7 & Ellen Deibert 2,8
With the increase in knowledge and management of sport-related concussion over the last 15 years, there has been a shift from a grading scale approach to an individualized management approach. As a result, there is an increased need to better understand the factors involved in delayed recovery of concussion. The purpose of this retrospective study was to examine factors that may be associated with recovery from sport-related concussion in student athletes aged 11 to 18 years old.
Cognitive and physical symptoms of concussive injury in children: a detailed longitudinal recovery study
Authors: Louise Crowe,1 Alex Collie,2 Stephen Hearps,3 Julian Dooley,1 Helen Clausen,4 David Maddocks,5 Paul McCrory,6 Gavin Davis,7 Vicki Anderson1
Recovery from concussion sustained in childhood and adolescence is poorly understood. We explored patterns of recovery for neurocognition and postconcussive symptoms following concussion in children and adolescents.
Post-exertion neurocognitive test failure among student-athletes following concussion
Authors: NEAL MCGRATH1, WAYNE M. DINN1,2, MICHAEL W. COLLINS3, MARK R. LOVELL3, R. J. ELBIN3, & ANTHONY P. KONTOS3
The purpose of the present study was to examine post-exertion (PE) neurocognitive performance among student athletes following concussion who were asymptomatic and returned to baseline normal neurocognitive test levels at rest. This study examined the neurocognitive performance of a sub-set of student-athletes who ‘failed’ to perform at baseline levels of neurocognitive function, i.e. exhibited downward reliable change index (RCI) alterations following a moderate exertional protocol during recovery from concussion.
Concussion in Rugby: Insights, Incidence and Intervention
Authors: Dr Jon Patricios
Concussion is a traumatic brain injury resulting from a direct or indirect blow to the head causing alterations in brain function. It is a complex pathophysiological process that may manifest in a number of ways reflecting physical, emotional, cognitive and sleep disturbances. Rugby Union is a collision sport with numerous phases of contact on the field resulting in the potential for collisions involving the head. The main area of play causing concussions is the tackle. Distinguishing features of rugby that impact on injury management are that it is a continuous, multiple-sprint, un-helmeted collision sport in which players are only allowed to wear limited, padded protective gear.
Vestibular and balance issues following sportrelated concussion
Authors: Tamara C. Valovich McLeod & Troy D. Hale
To review relevant literature regarding the effect of concussion on vestibular function, impairments, assessments and management strategies. Dizziness and balance impairments are common following sport-related concussion. Recommendations regarding the management of sport-related concussion suggest including tests of balance within the multifactorial assessment paradigm for concussive injuries.
Exercise Prescription Patterns in Patients Treated with Vestibular Rehabilitation After Concussion
Authors: Bara A. Alsalaheen1, Susan L. Whitney1,2,3, Anne Mucha2, Laura O. Morris2, Joseph M. Furman3 & Patrick J. Sparto1,2,3*
Individuals with concussion often complain of persistent dizziness and imbalance, and these problems have been treated with vestibular rehabilitation exercises. The purpose of this study is to describe the vestibular rehabilitation exercise prescriptions provided to individuals after concussion.
Comparison and utility of King-Devick and ImPACT® composite scores in adolescent concussion patients
Authors: B. Joel Tjarks a,⁎, Jason C. Dorman b, Verle D. Valentine c, Thayne A.Munce b,d, Paul A. Thompsone, Shanna L. Kindt c, Michael F. Bergeronb,d,f a Sanford
To examine the diagnostic value of KD, by comparing KD with post-concussion symptom scale (PCSS) and ImPACT® composite scores.We hypothesized that KD would be correlated with visual motor speed/memory (VMS, VIS) and reaction time (RT), because all require cognitive visual processing. We also expected parallel changes in KD and PCSS across recovery.
A review of modifying factors affecting usage of diagnostic rating scales in concussion management
Authors: Alexa Dessya,∗, JonathanRasoulia, AlexGometzb, TanvirChoudhria
Sport-related concussion has gained increasing recognition as a result of recent legislation, public health initiatives and media coverage. Moreover,there have been substantial paradigm shifts in the management of concussion. This article will discuss the variables that affect the use of diagnostic rating scales such as ImPACT and SCAT in the current management of concussed individuals.
