    Abstract
    Background. Individuals with brain impairment (BI) are less active than the general population and have increased risk of chronic disease. Objective. This controlled trial evaluated the efficacy of a physical activity (PA) intervention for community-dwelling adults with BI. Methods. A total of 43 adults with BI (27 male, 16 female; age 38.1 ± 11.9 years; stage of change 1-3) who walked as their primary means of locomotion were allocated to an intervention (n = 23) or control (n = 20) condition. The intervention comprised 10 face-to-face home visits over 12 weeks, including a tailored combination of stage-matched behavior ...

    Background. Individuals with brain impairment (BI) are less active than the general population and have increased risk of chronic disease. Objective. This controlled trial evaluated the efficacy of a physical activity (PA) intervention for community-dwelling adults with BI. Methods. A total of 43 adults with BI (27 male, 16 female; age 38.1 ± 11.9 years; stage of change 1-3) who walked as their primary means of locomotion were allocated to an intervention (n = 23) or control (n = 20) condition. The intervention comprised 10 face-to-face home visits over 12 weeks, including a tailored combination of stage-matched behavior change activities, exercise prescription, community access facilitation, and relapse prevention strategies. The control group received 10 face-to-face visits over 12 weeks to promote sun safety, healthy sleep, and oral health. Primary outcomes were daily activity counts and minutes of moderate-to-vigorous-intensity PA (MVPA) measured with the ActiGraph GT1M at baseline (0 weeks), postintervention (12 weeks) and follow-up (24 weeks). Between-group differences were evaluated for statistical significance using repeated-measures ANOVA. Results. MVPA for the intervention group increased significantly from baseline to 12 weeks (20.8 ± 3.1 to 31.2 ± 3.1 min/d; P = .01), but differences between baseline and 24 weeks were nonsignificant (20.8 ± 3.1 to 25.3 ± 3.2 min/d; P = .28). MVPA changes for the control group were negligible and nonsignificant. Between-group differences for change in MVPA were significant at 12 weeks (P = .03) but not at 24 weeks (P = .49). Conclusion. The 12-week intervention effectively increased adoption of PA in a sample of community-dwelling adults with BI immediately after the intervention but not at follow-up. Future studies should explore strategies to foster maintenance of PA participation.
