Overground and Virtual Reality Gait Speed Are Associated With Atypical Symptom Reporting in Active Duty Service Members With a History of Mild to Moderate Traumatic Brain Injury

We examined rates of Symptom Validity Test (SVT) failure in active duty military service members with a history of mild-moderate TBI and its impact on gait speed. Setting: Intensive Outpatient Program at the National Intrepid Center of Excellence at Walter Reed National Military Medical Center. Participants: Participants were 84 active duty service members with a history of mild-moderate TBI classified as SVT pass (n = 49) or SVT fail (n = 35). Design: Retrospective study. Main Measures: Overground preferred and fast walking speed as well as Computer Assisted Rehabilitation Environment (CAREN) gait speed were recorded. Participants completed the Neurobehavioral Symptom Inventory and the Validity-10 was used to assign patients into the SVT pass and SVT fail groups. Gait speed metrics were compared across these groups and test operating characteristics were calculated. Results: Approximately 42% of the sample was classified into the SVT fail group. All 3 gait speed measures were significantly slower in the SVT fail group than in the SVT pass group (Ps
