Official title
Functional Mechanism of Neural Control in Persistent Post-Concussion Symptoms Convergence Insufficiency
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Our successful R01 discovered 1) the neural mechanistic difference between typically occurring convergence insufficiency (TYP-CI) and binocularly normal controls and 2) the underlying mechanism of office-based vergence and accommodative therapy (OBVAT) that is effective in remediating symptoms. Adolescent and young adult concussion is considered a substantial health problem in the United States where our team has shown that about half of patients with persistent post-concussion symptoms have convergence insufficiency (PPCS-CI), causing significant negative impact associated with reading or digital screen-related activities, and is believed to be one factor causing delayed recovery impacting return to school, sports, or work. The results of this randomized clinical trial will impact the lives of adolescents and young adults with PPCS-CI to guide professionals on how to manage and treat those with PPCS-CI by 1) comparing the differences between PPCS-CI and TYP-CI, 2) discovering the neural mechanism of OBVAT for PPCS-CI compared to standard-community concussion care, and 3) determining the effectiveness of 12 one-hour sessions compared to 16 one-hour sessions of OBVAT.
