| Outline of Final Research Achievements |
During the research period, the COVID-19 pandemic made sports activities difficult, resulting in a decrease in concussion occurrences and making it impossible to collect data before and after the sports season. Consequently, the research period was extended. Ultimately, eye movement measurements were conducted on 36 individuals. In this study, specific changes were observed in the eye movements of subjects compared to healthy individuals, and the measurements improved during the recovery process of concussion symptoms, allowing for objective and quantitative evaluation. Based on these observations, further analysis was conducted to determine which types of evaluation items within SCAT5 correlated with the recovery status of eye movements. Ultimately, it was revealed that impairments in eye movement were more strongly correlated with physical balance disturbances than with psychological disorders. These findings were eventually published in an English journal.

| Academic Significance and Societal Importance of the Research Achievements |
スポーツ脳振盪は,明確な症状のない多彩な症状であるために見逃され, 科学的根拠のない感情的な励ましのみで競技復帰を余儀なくされてきた. 脳振盪は画像所見等の客観的所見もなく, 回復も目に見えるものではない. 本研究は, 脳振盪患者の眼球運動を詳細に解析し脳への障害程度が明らかとなり, さらに, 脳振盪が回復する経過を眼球運動計測することで把握することができ, スポーツの安全性向上が可能となった.
