The Use Of P3b As An Indicator Of Neurophysiologic Change From Subconcussive Impacts In Football Players, Jeffrey S. Brooks

Electronic Thesis and Dissertation Repository

There is a growing appreciation in research that subconcussive impacts may affect cognitive functioning. Canadian University football players (n=45) were separated into three groups based on their position/skill (small skilled, big skilled and big unskilled). An impact measuring device (GForceTracker) was used to record the number of impacts that each player experienced in a season. Player groups were separated into two levels of impact exposure: low and high. Players completed baseline, midseason, postseason, and follow-up neurophysiological tests (four months later) to measure P3b amplitude in response to a visual oddball paradigm, and high versus low impact subgroups for each player …

The Effects Of Hypohydration On Neurocognitive, Balance, Vestibular Ocular Motor Functions And Mood State, Satoshi Iida

Graduate Theses and Dissertations

Inconsistent findings have been observed on the impact of hydration state on cognitive functions. The isolated effect of hypohydration on neurocognitive performance, balance, vestibular ocular motor function and mood outcomes in widely used concussion assessment tools has not been studied. The purpose of this study was to investigate how hypohydration affected the results in concussion testing batteries. A single-blind randomized crossover design was used. Thirteen healthy males (22 ± 4y, 180.9 ± 5.7cm) without history of concussion within the past six months or any condition or disease that could influence outcome measurements participated in this study. Each subject completed concussion …

Relationship Between The Romberg Test And The Wii Basic Balance Test And Cognition In Athletes With Concussion, Nicholas G. Murray, Anthony P. Salvatore, Arthur Islas, Joseph Tomaka, Rebecca J. Reed-Jones

Department of Health Sciences and Kinesiology Faculty Publications

Background: Approximately 30% of individuals with a sport-related concussion present with postural instability. Multiple clinical balance tests exist to diagnose postural instability; yet little is known about the potential relationship between these type of postural assessments and cognition post-concussion. Aim: The purpose of the current study was to assess the relationship between the Romberg test, the Wii Fit basic balance test (WBBT), and the composite scores on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) test in a sample of athletes with concussions.

Methods: 55 post-concussed athletes (40 male) completed the Romberg Test (RT) (−/+), the WBBT, and ImPACT test. …

The Effects Of Caffeine On Reaction Time Of Two Neurocognitive Tests, Kyle Petit

Theses and Dissertations

Context: A concussion is defined as a traumatically induced transient disturbance of the brain caused by a biomechanical force. These problematic injuries can prevent athletes from participating in physical activity for a number of days, weeks, or even months. Caffeine is known for improving mental alertness in everyday tasks and is found in many popular drinks such as, coffee, tea, energy shots, and even soda. Due to its increase in memory, mental alertness, and concentration, caffeine could potentially be utilized to improve the outcomes of post-concussion neurocognitive testing. This improvement would allow athletes to return to play before they have …

Longitudinal Examination Of Perceived Stress And Depression Symptomology In Division I Student-Athletes, Bobby Daigle

Electronic Theses and Dissertations

CONTEXT: Concussions are all too prevalent in amongst athletes. Concussions make up almost 5 percent of all collegiate athletic injuries. Concussions have been linked with many long lasting effects including depression and increased stress or anxiety.

OBJECTIVE: To longitudinally examine post-concussion depression and stress levels in National Collegiate Athletic Association Division 1 athletes.

DESIGN: Descriptive longitudinal study.

SETTING: National Collegiate Athletic Association Division I collegiate athletics.

PARTICIPANTS: Concussed and uninjured Division I collegiate athletes, ages 18-22, competing in football, women’s soccer, baseball, softball, and women’s track.

INTERVENTION(S): Participants completed the CES-D at baseline, 1 week, 1 month, and 3 months …

Assessment Of Anti-Saccades Within 24 To 48 Hours Post-Concussion, Nathan D'Amico

Electronic Theses and Dissertations

INTRODUCTION: Oculomotor control dysfunction is present in about 90% of concussed athletes, with anti-saccades being the most prominent. PURPOSE: To investigate anti-saccades, reflexive gaze deviations from a fixed point or area of interest, between NCAA Division I athletes 24 to 48 hours post-concussion (PC) and healthy, matched controls (MC). METHODS: 10 PC (4 female, 6 male; age: 18.9 ± 0.9 years) and 10 MC (4 female, 6 male; age: 18.3 ± 0.6 years) wore a monocular eye tracker (240Hz) while performing 2 trials of the 60-second WiiFit Soccer Heading game. During play, participants were instructed to not deviate their gaze …
