A randomized trial of two treatments for mild traumatic brain injury: 1 year follow-up

The purpose of this study was to provide 1 year follow-up data to a previou s paper that compared single-session (SS) treatment to treatment-as-needed (TAN) outcomes for mild traumatic brain injury (MTBI) survivors at 3 months post-injury. participants were 105 adults with MTBI who were recruited fro m consecutive admissions to two hospital emergency wards, and randomly assi gned to either the SS or TAN modality. No group differences in outcome were evident at 12 months post-injury. As well, improvements seen in the groups after 3 months were maintained at 12 months. As improvements between 3 and 12 months were negligible, self-reported improvement after a treated MTBI typically occurred within the first 3 months. Brief educational interventio n given soon after MTBI appears to be as helpful as more intensive treatmen t for most MTBI survivors for at least 12 months post-injury.
