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.
