Official title

Effects of Repetitive Subconcussive Head Impacts on Ocular-motor Function and Brain-derived Blood Biomarker

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Repetitive head impacts in sports and military may cause deleterious effects in the nervous system. Investigators' previous works in football players have shown promising results in prediction of concussion and prevention of long-term defect using eye-movement paradigm (ocular-motor system) and blood biomarker. However, acute head impact effects on aforementioned parameters remain unknown. Thus, to answer a critical research question that whether or not ocular-motor system and brain-derived blood biomarker may be acutely altered following 10 successions of controlled soccer heading. To answer the question, investigators hypothesized that acute bout of soccer heading will not elicit noticeable change in subject's symptoms but to induce a transient defect in the ocular-motor system and increase plasma expression of brain-derived biomarker.
