Repetitive mild traumatic brain injury (rmTBI) results in elevated Neurological Severity Scores (NSS) and transient vestibulomotor deficits. a rmTBI mice +/− were assessed with an NSS at 1, 4, 24, 48, and 72 h post-injury, as well as at 7-day and 1-month time points. Repetitive mTBI mice exhibited significantly elevated scores, compared to control mice, and mice fed GF diets had reduced NSS score compared to rmTBI alone. b Mice underwent wire grip testing 1 h after TBI and on post-injury days 1–7. rmTBI resulted in short-lived vestibulomotor dysfunction, compared to controls, at 1 h to 7 days post-injury (Kruskal-Wallis). There were significant differences between rmTBI mice plus diets and rmTBI alone on post-injury days 1–7. *p < 0.05 versus control mice. **p < 0.01 versus rmTBI mice. Values are mean ± SD
