About this study

Official title: The Effects of Head Trauma on Biological Markers and Neurologic Function in Collegiate Athletes: a Prospective Investigation

Recently, researchers and clinicians have examined many different forms of concussion testing aimed to assess if a brain injury has occurred and to what degree it affects the individual being tested. Due to the multifaceted and complex presentation of concussive injuries and the unknown effects of repeated head trauma, it is unlikely that a single test of physiological or behavioral function will reflect the full range of injury-related damages from a concussive event or from a series of cumulative head traumas, as well as the injury response within brain tissue. However, by combining a variety of objective assessments which may detect structural and functional alterations following head trauma into a single study, a clearer understanding of the multi-faceted presentation resulting from head trauma may be identified. The identification of biomarkers and the utilization of objective and clinically feasible tools will provide a method to assess three domains across multiple systems affected by head trauma: 1) the prognostic value of initial concussion assessments to identify injury severity and factors responsible for prolonged recovery, 2) the temporal window of recovery and potential vulnerability of brain tissue post-injury, and 3) the long-term alterations associated with repeated head trauma exposure.

Read the detailed description

Student athletes from contact and collision sports, as well as non-contact sports, will complete a comprehensive assessment of neurological and behavioral function before and after a season of participation. Additionally, those who sustain a concussion will undergo a post-injury testing timeline where they are assessed within 5 days of injury and again at the following time points: 3-4 weeks, 3 months, 6 months, and 1 year post-injury. Each individual who completes testing as a concussion subject will be matched with a healthy control subject by height, weight, age, sport, and position, and each control subject will complete the same protocol in similar time increments as subjects with concussion.

Through this study design, we hypothesize that we will be able to detect objective deficits resulting from concussion within one week of injury and determine the feasibility and added value of a comprehensive neurological and behavioral testing battery through a comparison of metrics between injured and healthy collegiate student athletes. Additionally, we hypothesize that for athletes who do not sustain a concussion, decrements between the pre-season and post-season time points will be greater in those who participate in collision/contact sports in comparison to those who participate in non-contact sports. Thus, outcomes from this study will enhance the understanding of the pathophysiology of concussion through a rigorous laboratory testing component, but with simultaneous direct translation to clinical implementation through the use of a highly-feasible clinical testing paradigm that possesses potential for ubiquitous and widespread use throughout sports medicine practices.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT02354469
Study groupRoleWhat they receive
Contact/Collision Sport AthletesCollegiate athletes who participate in contact or collision sports will be assessed on a comprehensive battery of tests during pre-season and post-season assessments.
Non-contact Sport AthletesCollegiate athletes who participate in non-contact sports will be assessed on a comprehensive battery of tests during pre-season and post-season assessments.
Post-ConcussionCollegiate athletes who sustain a concussion will be assessed on a comprehensive battery of tests from the time of injury and incrementally throughout the following year post-injury.
Healthy ControlCollegiate athletes who do not sustain a concussion but match the demographic profile of an individual enrolled as a post-concussion subject, will be assessed on the same tests and in a similar timeline as post-concussion subjects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Dynamic Balance Control

    For balance control measures, the primary data will come from accelerometers placed on specific anatomical landmarks to assess whole body movement. Peak accelerations and velocities of an estimated center-of-mass during gait under single-task and dual-task conditions will identify how divided attention tasks affect whole body balance control.

    Measured: 1 year

Secondary outcomes (4)
  1. Cognitive Function

    Concussion-Rapid Assessment Module, simple and choice reaction times, Trail Making Tests A and B, Balance Error Scoring System, and static and dynamic visual acuity will be assessed.

    Measured: 1 year

  2. EEG signals

    We plan to examine a variety of conventional EEG measures including resting-state power and functional connectivity, as well as task-related evoked potentials, functional connectivity changes, and event-related spectral perturbation.

    Measured: 1 year

  3. Blood and Urine samples

    We will primarily investigate previously documented markers of neuronal integrity GFAP, UCH-L1, and SB100 (blood) and levels of protein concentration in urine

    Measured: 1 year

  4. Neuroimaging

    Primary measures will include: gross and regional volumes of brain structures, water molecule diffusion (axial diffusivity, fractional anisotropy, radial diffusivity, and mean diffusivity), and neurochemical imaging (levels of NAA, Cr, Cho, Glu, GSH, and MI).

    Measured: 1 year
