Inclusion Criteria: * For all Aims, participants may be either civilians, active duty military, or Veterans, and must: 1. have a diagnosis of mTBI based on VA/DoD criteria 2. be between 18-60 years old, 3. be able to stand unassisted for 10 minutes at a time 4. be outside of the acute stage (\> 2 weeks post-concussion) but within 6 months of their most recent mTBI and still reporting symptoms 5. have at least some measurable deficit in Vestibular/Ocular categories based on Concussion Profile Screen 6. have sufficient vision (corrected or uncorrected) for unassisted reading and performance of everyday personal tasks and independent community ambulation 7. have adequate hearing (without amplification) adequate for engaging in close-range personal or telephone conversation. Exclusion Criteria: * Participants must not: 1. have had or currently have any other injury, medical, or neurological illness that could potentially explain balance or vision deficits (e.g., CNS disease, stroke, epilepsy, greater than mild TBI, Meniere's, bilateral vestibular loss, recent lower extremity or spine orthopedic injury that impairs mobility) this includes unresolved symptoms from previous concussions 2. meet criteria for moderate to severe substance-use disorder within the past month, as defined by DSM-V 3. display behavior that would significantly interfere with the validity of data collection or safety during the study 4. be in significant pain during the evaluation (\> 7/10 by patient subjective report) 5. be a pregnant female (balance considerations) 6. been hospitalized for any brain injuries (separate from the emergency department) 7. have significant joint pain or recent musculoskeletal injury that limits walking or mobility 8. have had any major surgeries in the past year or amputation 9. use an assistive device 10. unable to stand barefoot 11. currently receiving rehabilitation services for their mTBI or injuries related to their concussion (if rehabilitation has been completed more than 1 month ago participants may still be included).
