Concussion frequently disrupts the visual system. Adolescents often endure lingering clinical symptoms related to vision after concussions, including blurriness, diplopia, reading challenges, light sensitivity, visually triggered headaches, and difficulties in tracking fast-moving objects (1). An estimated 15% of mild traumatic brain injury (TBI) cases result in post-concussion syndrome (PCS), with a minority requiring further evaluation and treatment due to persistent symptoms (2,3).

This study aimed to assess the risk of prolonged post-concussive symptoms in adolescents with exercise-induced vision dysfunction within 10 days of injury and explore potential correlations with abnormal oculomotor examination findings.

An estimated 15% of mild traumatic brain injury cases result in post-concussion syndrome.
Understanding the association between exercise-induced vision dysfunction and delayed recovery can guide physiotherapists in tailoring rehabilitation programs for adolescents with concussion.


  • Participants were enrolled between July 2018 and April 2020 from three university-affiliated sports medicine clinics shortly after experiencing a concussive head injury (typically within a 10-day window).
