Poster 16: A Randomized Controlled Trial of Exercise to Improve Mood After Traumatic Brain Injury

      Objective: To evaluate the impact of an exercise intervention on mood after traumatic brain injury (TBI). Design: Randomized controlled trial. Setting: Community. Participants: 80 sedentary subjects 6 months to 5 years after TBI randomized to exercise versus wait-list control. Interventions: Subjects participated in a 10-session intervention with individualized exercise and education. Main Outcome Measures: Beck Depression Inventory (BDI), 7-day exercise recall, Craig Handicap and Assessment Technique (CHART), Perceived Quality of Life (PQOL), and Pittsburgh Sleep Quality Index (PSQI). Results: The exercise group reported an increased number of days per week of exercise compared with controls (P=.004), but mood did not differ by group. To further explore the relationship between exercise and mood, we examined both treatment and control subject data at 10 weeks. Those who exercised more than 90 minutes a week had significantly lower BDI scores (P=.03), increased participation (CHART, P=.03), higher quality of life (PQOL, P=.03), and improved sleep (PSQI, P=.02) compared with those who exercised less than 90 minutes a week. Conclusions: Those who exercised in both groups reported better mood, participation, quality of life, and sleep. More effective exercise promotion interventions are needed for this population.
