RHI Interval Effects on Brain Health
Defining the Role of Repetitive Head Impact Time Intervals in Mitigating Subconcussive Neural Injury
Indiana University
102 participants
Aug 5, 2025
INTERVENTIONAL
Conditions
Summary
Military service members frequently experience repetitive insults or impacts to the head (RHIs). The purpose of the proposed randomized controlled trial is to understand how time intervals affect neurological responses to repetitive subconcussive head impacts.
Eligibility
Inclusion Criteria3
- Current soccer player (intercollegiate, club, intramural, recreational).
- At least 5 years of soccer heading experience (justification below).
- Ability to provide informed consent without a legally authorized representative (LAR).
Exclusion Criteria3
- Any head, neck, or face injury within the 6 months prior to enrollment, including concussions, that precludes participation in contact sports.
- Participants with eye conditions or diseases that could impact the blood vessels in the eye -such as but not limited to: glaucoma, macular degeneration, diabetic retinopathy.
- Determination that the participant is unsuitable for study entry or potentially unable to complete all aspects of the study based on the judgement of the Investigator.

Interventions
A standardized and reliable soccer heading protocol will be used for the experiment. Participants perform 16 headers or kicking with 1 header per 30 seconds. The sessions (twice per week for 4 weeks) will be separated by 24 hours.
A standardized and reliable soccer heading protocol will be used for the experiment. Participants perform 16 headers or kicking with 1 header per 30 seconds. The sessions (twice per week for 4 weeks) will be separated by 72 hours.
An Investigational version of the BrainScope FDA-cleared qEEG acquisition device will be used in this study. The investigational nature of the device is simply based on the code which does not produce a diagnostic result for the blinded researcher. Electrodes will be placed around the participant's forehead and scalp to acquire electrical readings of brain activity.
