The TCU Division I Collegiate Athlete Study

The study involves a total of one to three visits, depending on whether an athlete sustains an injury. If an enrolled athlete does not sustain an injury during their athletic season, they will only complete visit 1. If they do, they will complete visits 1, 2, and 3. In total, the expected time requirement is less than 1 hour across the season.

This study will be a two year project in which athletes will be tested around the beginning of their respective sport season.

The PI or Co-I will ask the potential study participant questions regarding inclusion/exclusion criteria. If the potential participant meets all inclusion criteria and no exclusion criteria exist, then the informed consent process can begin. The PI or Co-I will review the informed consent document with the participant. If the participant agrees to be a part of the research study, then the informed consent and authorization form (HIPAA) will be signed electronically.

As part of the 1st Aim of the study: 1 visit, approximately 15 minutes

Information to be collected after consent but does not require the subject to be present:

• Demographic information, past medical history information and pre-participation examination results from University Athletics athlete health tracking system.
• Injury occurrence and characteristics during the yearlong season will be tracked and recorded by team athletic trainers and inputted into athlete health tracking system; Such data that will be collected includes but is not limited to: type of injury, location of injury, mechanism of injury, severity of injury, and time missed due to injury.

Initial Pre-season visit (approximately 15 minutes)

All subjects will perform:

• Sway Sport mobile application assessment tests: reaction time, impulse control, and selective attention (see explanation of study procedures for information on tests). All cognitive testing will be stopped if subject requests to stop. Tests will take approximately 5 minutes.
• Movement tests: jumping, landing and balance tasks (see explanation of study procedures for information on tests). All physical movement and performance tests will be stopped if subject requests to stop or a significant risk of injury is identified. Tests will take approximately 10 minutes.

Initial pre-season testing should take approximately 15 minutes for actual testing with time requirement of no more than 30 minutes if completing testing in a group setting.

For athletes who sustain non-concussive injuries, standard of care rehab assessments will be collected over the course of recovery and at time of return to play by the treating physical therapist or athletic trainer. These standard of care measures utilized will be up to the rehabilitation provider in their practice and will not add time nor commitment from a research perspective for study participants but may be collected as data to describe injury and recovery characteristics.

As part of the 2nd Aim of the study: 2 additional visits, approximately 15 minutes each Subjects who sustain a concussion, will be identified, and diagnosed by a team physician. As part of the standard University Athletics protocol, these subjects will undergo repeat testing of the following, until they meet satisfactory baseline criteria that is decided upon by the treating physician and athletic trainer.

• C3Logix neurocognitive testing (see explanation of study procedures for information on tests)
• Subjective symptom reporting scale as designated by team physician

As part of the study protocol, these subjects will be asked to return for the following repeat testing:

2nd Visit - during week following concussive injury (approximately 15 minutes)

Only subjects that sustain a concussion will perform:

• Sway Sport mobile application assessment tests: reaction time, impulse control, and selective attention. All cognitive testing will be stopped if subject requests to stop. Tests will take approximately 5 minutes.
• Movement tests: jumping, landing and balance tasks. All physical movement and performance tests will be stopped if subject requests to stop or a significant risk of injury is identified. Tests will take approximately 10 minutes.

3rd Visit - at time of return to play following concussive injury (approximately 15 minutes)

Only subjects that sustain a concussion will perform:

• Sway Sport mobile application assessment tests: reaction time, impulse control, and selective attention. All cognitive testing will be stopped if subject requests to stop. Tests will take approximately 5 minutes.
• Movement tests: jumping, landing and balance tasks. All physical movement and performance tests will be stopped if subject requests to stop or a significant risk of injury is identified. Tests will take approximately 10 minutes.

For athletes who sustain a concussive and/or any non-concussive injuries, standard of care rehab assessments will be collected over the course of recovery and at time of return to play by treating physical therapist or athletic trainer. These standard of care measures utilized will be up to the rehabilitation provider in their practice and will not add time nor commitment from a research perspective for study participants but may be collected as data to describe injury and recovery characteristics.

Inclusion criteria

• If they are a current National Collegiate Athletics Association (NCAA) student-athlete
• If they are between 17 and 30 years of age - with recent extensions in eligibility requirements for NCAA sports, athletes are participating at increasingly higher ages. Similarly, early enrollees are common and can be included in the study prior to turning 18.

Exclusion criteria

• If they are not a current National Collegiate Athletics Association (NCAA) student-athlete
• If they are not between 17 and 30 years of age
• If they are currently experiencing an injury that limits them from completing testing procedures
