Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen

Open Access Theses & Dissertations

Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …

Does Knowledge Of Concussion Symptoms Influence An Athlete's Self-Report Of History Of Concussion Across Age Groups?, John Pfirman

Open Access Theses & Dissertations

Purpose: The purpose of this study was to determine if an athlete's self-report of a history of concussion would increase if they are provided with information about concussions.

Study Design: This study used a group design pre-test information group and a post-test information group matched for age.

Methods: Prior to cognitive testing, the athletes were divided into an experimental and control group. The experimental group received information about concussions before taking the cognitive test. The control group did not receive concussion information before cognitive testing. Both groups completed a questionnaire following testing that asked: "Based on your experience here today, …

Predicting Protracted Recovery From Sports-Related Concussion Using Computerized Neurocognitive Test Scores And Symptom Cluster Scores, Amanda Sepulveda

Open Access Theses & Dissertations

Background: A previous study showed that symptom evaluation, in conjunction with computerized neurocognitive testing, improved predictions of protracted recovery in a group of male high school football players. The determination of prognosis following sports-related concussion can be used to facilitate return-to-play and academic decision making in concussion management.

Purpose: The purpose of this study was to replicate and extend previous research in determining the accuracy, sensitivity, specificity, and predictive value of computerized neurocognitive test scores and symptom cluster scores in predicting protracted recovery following sports-related concussion.

Study Design: Systematic replication, Cohort study (prognosis)

Methods: 30 concussed collegiate athletes were followed …
