Longitudinal Monitoring of Head Impacts in Elite Junior Ice Hockey

This study aims to better understand how head impacts during ice hockey affect the brain and body, especially in young athletes. Even when players do not show clear signs of concussion, these repeated impacts may cause subtle changes in the brain's structure and in how the body regulates basic functions, such as heart rhythm and attention. This study will follow elite junior ice hockey players over the course of one full season to better understand the effects of repeated head impacts. Using a small helmet sensor (Bearmind) and video analysis, researchers will record and analyze every head impact that occurs during games and practices. Three times during the season - before, mid-season, and after - players will complete assessments of heart rate variability (using Polar H10 monitors) and a dual-task test that measures attention and coordination. After any diagnosed concussion, players will be reassessed with both heart rate variability and dual-task testing at 3 days post-injury. Following that, dual-task testing alone will be repeated every 3 days until return to sport. Players who experience a severe head impact, as detected by the helmet sensor, will also be evaluated 3 days after the impact with both heart rate variability and dual-task testing, even if no concussion symptoms are present. By combining these measures, the study aims to detect early physiological and cognitive changes following head impacts, improve understanding of sub-concussive effects, and support better prevention and management strategies for young athletes.

Female Concussion Head Cooling

This research is being done to examine the benefits of a 28 day head cooling intervention on cognition, inflammation of the brain, sleep quality, menstrual symptom interaction, and mood in acutely concussed females. Brain cooling has been shown to cause temporary symptom relief after traumatic brain injury, but its implications for decreasing timeline of full concussion recovery, particularly in females during periods of confounding neuropsychological menstrual symptoms, remains unexplored.

Dizziness Due to Visual Stimuli in Patients With Concussion and Other Causes of Dizziness: Examination of Balance Behaviour

This research project aims to measure how balance is affected by special visual stimulation. Dizziness caused by complex moving visual patterns, known as optokinetic stimulation, is usually called visually induced dizziness (VID). The study includes patients with persistent symptoms after a concussion and those with non-traumatic dizziness. Healthy participants serve as a control group for the comparison of balance and symptom responses. The optokinetic stimulation is done using either a physical rotating disk or a virtual reality (VR) headset. The visual effects are created by bright moving dots. During the stimulation, these patterns move in a specific manner and directions while the subject's balance is recorded. Symptoms such as dizziness, headache, and nausea are also documented. The goal of this project is to improve objective diagnosis of VID. By comparing patients and healthy subjects, the study aim to assess the severity of the disorder. It is also assumed that using different visual stimuli during the balance assessment will offer more sensitive and accurate results. In the long term, this innovative assessment method shall support clinicians to establish the diagnosis of VID, and improve the treatment and management of patients with VID.

Multidimensional Sleep Health Intervention to Optimize Concussion Recovery

Following adolescent concussion, poor sleep health is common and relates to the development of persisting post-concussion symptoms, and uninjured adolescents (independent of concussion) also commonly experience sleep insufficiency. Given the sparse guidance that exists for clinicians to provide evidence-based sleep health recommendations for adolescents with a concussion, the primary objectives of this prospective randomized clinical trial of adolescents with a recent concussion are to discover if a multidimensional and prescriptive sleep health intervention leads to: 1) faster symptom resolution time, better sleep quality, or longer sleep duration; and 2) improved sleep habits, mental health, or academic engagement, relative to standard-of-care post-concussion sleep health guidance. Findings from this research will provide the basis for more precise sleep health recommendations for adolescents who experience a concussion.

The TCU Division I Collegiate Athlete Study

The overall objective of this study is to identify risk factors for two of the most common types of injuries in collegiate athletics - orthopedic injuries and concussion injuries. Aim 1 of this study is to investigate risk factors for orthopedic injuries from a brief testing battery developed by the research team. Aim 2 of this study is to investigate risk factors for concussion injuries and subsequent sequelae after returning to play from concussion from the same brief testing battery developed by the research team. Additionally, we will examine the relationships between orthopedic injuries and concussion injuries in the collegiate athlete. Participants will participate in a pre-season battery of tests that include: * Balance assessment * Jump testing * Strength testing * Neurocognitive testing Subjects who sustain an injury will undergo repeat testing for comparison to baseline measures. Further, retrospective chart reviews of past medical history and prospective injury tracking will be collected on all subjects.
