BACKGROUND: Baseline visual acuity (VA) loss from static to dynamic head conditions assessed using the Dynamic Visual Acuity Testing (DVAT) have not been established in NCAA football players. DVAT assesses the Vestibulo-Ocular Reflex (VOR) which is measured in Logarithm of the Minimum Angle of Resolution (logMAR). Decreased VA beyond baseline measures may detect VOR impairment and impact treatment protocols and assist in return to play decisions post-concussion. HYPOTHESIS/PURPOSE: To establish normative VA mean scores during a static head posture as well as dynamically during the DVAT with a head speed of 150 deg/s in the pitch (vertical) and yaw (horizontal) planes rotating 20 degrees in each direction...

Athletes occasionally attempt to lower their baseline scores to mask the effects of a concussion during post-trauma assessment, a phenomenon known as sandbagging. In order to help prevent this from occurring, the Rey Dot Counting Test (DCT) was examined as a potential measure to be added to a Division II university screening battery. Investigators utilized samples of athletes at baseline and non-athlete students instructed to provide honest effort or suppressed effort, either naïvely or coached. The results support the use of the DCT as a valid measure of suboptimal performance when using modified norms established from collegiate populations...

Neuropsychologists regularly conduct sport-related concussion (SRC) evaluations, although research has not tracked these assessment practices. As part of a survey of neuropsychological test usage, we analyzed data from 215 neuropsychologists who conduct SRC evaluations. Only 15% reported conducting baseline assessments of athletes as part of a sports program and 92% evaluate athletes' post-concussion without baseline data. The majority of respondents use a full battery, considered the most reliable approach for assessing concussion symptoms in athletes...

The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called "sandbagging," in order to return to their baseline cognitive scores, and thus to play, more quickly...

OBJECTIVE: The Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) is commonly used to assess baseline and post-injury cognition among athletes in North America. Despite this, several studies have questioned the reliability of ImPACT when given at intervals employed in clinical practice. Poor test-retest reliability reduces test sensitivity to cognitive decline, increasing the likelihood that concussed athletes will be returned to play prematurely. We recently showed that the reliability of ImPACT can be increased when using a new composite structure and the aggregate of two baselines to predict subsequent performance...

CONTEXT: The sideline assessment of concussion is challenging, given its variable presentations, the limited sensitivity and specificity of sideline assessment tools, and how the presentation of the injury evolves over time. In addition, the diagnostic process, as well as the tools used to assess and manage concussion, continue to progress as research and what we know about concussion advance. This paper focuses on the initial assessment on the sideline by reviewing the concussion-evaluation literature, drawing from clinical experience to emphasize a standardized approach, and underscoring the importance of both familiarity with the athlete and clinical judgment...

CONTEXT: Recent changes to postconcussion guidelines indicate that postural-stability assessment may augment traditional neurocognitive testing when making return-to-participation decisions. The Balance Error Scoring System (BESS) has been proposed as 1 measure of balance assessment. A new, freely available software program to accompany the Nintendo Wii Balance Board (WBB) system has recently been developed but has not been tested in concussed patients. OBJECTIVE: To evaluate the feasibility of using the WBB to assess postural stability across 3 time points (baseline and postconcussion days 3 and 7) and to assess concurrent and convergent validity of the WBB with other traditional measures (BESS and Immediate Post-Concussion Assessment and Cognitive Test [ImPACT] battery) of assessing concussion recovery...

Objective: The use of normative data is a hallmark of the neuropsychological assessment process. Within the context of sports-related concussion, utilizing normative data is especially essential when individualized baseline data are unavailable for comparison. The primary purpose of this study was to establish normative data for a comprehensive neuropsychological test battery used in the assessment of sports-related concussion. A secondary aim was to provide normative data for pertinent demographic variables relevant to the assessment of college athletes, including sex, previous head injuries (PHI), and history of attention deficit hyperactivity disorder (ADHD)/learning disability (LD)...

Objective: Non-concussed individuals may report a variety of concussion-like symptoms even in the absence of a diagnosed brain injury. Previous studies described concussion-like symptom reporting in adolescent athletes. This study provides complementary data on concussion-like symptoms in collegiate athletes. Methods: We analyzed baseline symptom scales from 738 collegiate athletes (452 men and 286 women) who completed either the Sport Concussion Assessment Tool, 3 Symptom Evaluation (S3SE; n = 377) or the Post-Concussion Scale (PCS; n = 361) and determined if subjects met criteria for diagnosis of International Classification of Diseases 10th Revision (ICD-10) postconcussional syndrome...

OBJECTIVES: Traumatic Brain Injury (TBI) is a common and debilitating injury that is particularly prevalent in patients over 60. Given the influence of head injury on dementia (and vice versa), and the increased likelihood of ground-level falls, elderly patients are vulnerable to TBI. Educational interventions can increase knowledge and influence preventative activity to decrease the likelihood of further TBI. We sought to determine the efficacy of interactive tablet-based educational interventions in elderly patients on self-reported knowledge...
