OBJECTIVE: To test the safety, feasibility, and effectiveness of reducing sitting
time in stroke survivors. DESIGN: Randomized controlled trial with
attention-matched controls and blinded assessments.
SETTING: Community.
PARTICIPANTS: Stroke survivors (N=35; 22 men; mean age, 66.9+/-12.7y).
INTERVENTIONS: Four counseling sessions over 7 weeks with a message of sit less
and move more (intervention group) or calcium for bone health (attention-matched
control group). MAIN OUTCOME MEASURES: Measures included safety (adverse events,
increases in pain, spasticity, or fatigue) and feasibility (adherence to trial
protocol). Secondary measures included time spent sitting (including in prolonged
bouts >/=30min), standing, and stepping as measured by the thigh-worn
inclinometer (7d, 24h/d protocol) and time spent in physical activity of at least
moderate intensity as measured by a triaxial accelerometer. The Multimedia
Activity Recall for Children and Adults was used to describe changes in use of
time. RESULTS: Thirty-three participants completed the full protocol. Four
participants reported falls during the intervention period with no other adverse
events. From a baseline average of 640.7+/-99.6min/d, daily sitting time reduced
on average by 30+/-50.6min/d (95% confidence interval [CI], 5.8-54.6) in the
intervention group and 40.4+/-92.5min/d in the control group (95% CI, 13.0-93.8).
Participants in both groups also reduced their time spent in prolonged sitting
bouts (>/=30min) and increased time spent standing and stepping. CONCLUSIONS: Our
protocol was both safe and feasible. Participants in both groups spent less time
sitting and more time standing and stepping postintervention, but outcomes were
not superior for intervention participants. Attention matching is desirable in
clinical trials and may have contributed to the positive outcomes for control
participants.
