Background: Concussions are frequent injuries sustained by collegiate athletes. They are often underdiagnosed and may lack adequate treatment due to a lack of standardization in diagnosis and return to play guidelines. Current research suggests that there is an increased risk of…

Blast-induced neurotrauma (BINT) is a newly emerging re-occurrence of an old combat-related injury in U.S. military troops returning from deployment in Afghanistan and Iraq. BINT is leading to a silent epidemic of symptomatic troops who face barriers to accessing healthcare and …
Objective : To examine 1) adolescent communication comfort levels, 2) barriers to com-munication with systems of care (e.g., family, medical, school, athletic, friends), and 3) associations between communication comfort and demographic, injury characteristics, medical history, e…
Concussions are complex injuries that affect the brain and body in many ways. Symptoms such as nausea, headaches, and difficulty balancing can ensue for long periods of time in some cases. Sensory reweighting is a system within the body that helps us balance; it includes the vis…
Context: Individuals with a history of concussion are more likely to sustain subsequent concussions or musculoskeletal injuries. Underlying mechanisms are unclear; however, anxiety-related reaction time deficits may play a role.
Second injury risk following concussion merits improved return to play assessments. Two studies examined deficits in athletes with a concussion history (Cx): 1) a secondary analysis to investigate an area under the curve (AUC) assessment for cognitive recall; 2) a dual-task para…
Concussion is the most common form of traumatic brain injury (TBI). However, there is a disproportionate level of understanding between the acute and chronic impairments associated with traumatic brain injury. Specifically, problems maintaining balance during standing and walkin…
The purpose of this study was to determine whether pre-injury somatic symptoms influenced recovery time among adolescents who sustained sport-related concussion (SRC), and whether that relationship was influenced by postinjury anxiety or depression. Participants consisted of 153…
The current study examined whether persons with a history of mTBI exhibited greater cognitive decline in response to physiological arousal than healthy controls. It was hypothesized that individuals with a recent history of mTBI would demonstrate poorer cognitive functioning at …
Concussive injuries among youth are a serious public health concern in the United States, with increasing incidence leading the Centers for Disease Control and Prevention to classify these injuries a “silent epidemic.” Though most concussions in youth resolve within a few weeks,…
The purpose of this two-study dissertation was to determine how concussion history, career status, cumulative years of football exposure (study one), and activity status (study two) affect performance on sports-related concussion measures in healthy, elite athletes and non-athle…
Context: This study observed how the effects of a concussion change the quantity and quality of sleep in collegiate athletes. There is a lack of research pertaining to this topic, specifically collegiate athletes, and the changes in sleep outcomes during concussion recovery from…
The purpose of this study is to evaluate validate the memory and concentration sections of the Standardized Assessment of Concussion (SAC) from the SCAT5. Two studies were conducted. The first study examined item difficulty and discrimination using 10 new word lists of 3 version…
Concussion has been linked to an increased risk of lower extremity injury. It is hypothesized that residual postural control deficits due to delays in central processing speed or sensory reweighting are responsible for the increased risk. The purpose of this study was to evaluat…
Purpose: Sport-related concussions have shown to have effects on self-efficacy, oculomotor performance, reaction time and an increased risk of lower extremity injury. Most studies have been conducted to test the effects of acute concussions in athletes and not on long-term effec…
People who experience tinnitus after a concussion represent some of the most challenging clinical cases to see. However, little is known about the underlying mechanisms of this symptom. Concussion may facilitate tinnitus generation at the cortical level or may interfere with a p…
Background: Approximately 1.6 to 3.8 million concussions a year are sports-related concussions. However, a majority are unreported or do not get medical attention. Concussions can lead to increased functional impairments, long-term neurological deficits and in severe cases perma…
Cognitive efficiency—characterized via robust behavioral and physiological response dynamics, may provide clinically meaningful information with respect to dynamic concussion injury response and return to play considerations. Moreover, a feasible and ecologically valid method to…
The purposes of this study were to 1) compare the drop landing mechanics between individuals with and without a history of concussion and 2) investigate the effects of a mental fatigue intervention on drop landing outcomes among individuals with a history of concussion. It was h…
