Interventions for Convergence Insufficiency in Concussed Children

Objectives: A group of 264 diverse children, ages 11 to 17 years, with post‐concussion syndrome (4‐12 weeks post‐concussion injury) and symptomatic CI will be enrolled from 6 sites from across the United States, will be randomized to 12 weeks of: 1) standard care (SC), 2) SC plus simple convergence exercises (SC+), and 3) SC plus office‐based vergence/ accommodative therapy (SC+OBVAT). Primary Objective: To compare the effectiveness of SC, SC+, SC plus office‐based vergence/accommodative therapy for improving a composite outcome measure of clinical findings (near point of convergence and positive fusional vergence at near) in children 11‐17 years of age with concussion‐related CI after 12 weeks of treatment. ‐ Secondary outcome measures ‐ Objective measures of disparity vergence, accommodation, saccades, and smooth pursuit ‐ Quality of life measures ‐ Convergence Insufficiency Symptom Survey Concussion Version (CISS‐CON) ‐ PedsQL Version 4 For participants in any treatment group who not "successful" based on the composite score described above, additional/different treatment will be offered as an option after the primary outcome examination
