Objective To explore if a home exercise program (HEP) affects visio-vestibular function in concussed pediatric patients. Background A HEP can provide an equitable and cost-effective method for therapy targeted towards visio-vestibular deficits that are common following concussion. It is unclear if pediatric patients prescribed a HEP demonstrate improved visio-vestibular function. Design/Methods This observational study included 1,041 patients (59% female; age = 14.0 ± 2.5 years) reporting to a specialty care concussion center for an initial visit ≤28 days post-injury and follow-up ≤60 days post-injury. All patients completed a Visio-Vestibular Examination (VVE) at both timepoints consisting of 9 subtests: smooth pursuit, horizontal/vertical saccades and gaze stability, binocular convergence, left/right monocular accommodation, and complex tandem gait. Patients were prescribed a HEP (1–2 times/day) at initial visit consisting of exercises addressing visio-vestibular deficits. At follow-up, patients reported their progress: (1) has not done the HEP, (2) is currently doing the HEP, or (3) has completed the HEP. Primary outcomes included HEP progress, VVE subtests (normal/abnormal), and total VVE (abnormal = 2 + abnormal subtests). Chi-square tests with Bonferroni corrections were used to determine if abnormal VVE outcomes were associated with HEP status. Results At initial visit, 81 2(77.6%) patients presented with abnormal total VVE. At follow-up, the proportion of abnormal total VVE did not differ among patients not doing the HEP (101 [62.0%]), patients currently doing the HEP (516 [69.0%]), and patients who had completed the HEP (51 [69.0%]). However among VVE subtests, a lower proportion who completed the HEP presented with abnormal smooth pursuit (7.5%), horizontal (3.8%) and vertical (3.8%) saccades, and complex tandem gait (0%) relative to patients currently doing the HEP (p = 0.003) and patients not doing the HEP (p = 0.01). Conclusions Our findings indicate that patients who completed the HEP presented with improved elements of visio-vestibular function relative to those who did not start or were currently doing the HEP.
