Abstract

Objective: To describe patterns of sedentary behavior over 6 weeks among ambulatory people with subacute and chronic stroke. Design: Observational longitudinal study with assessments at baseline (T0) and week 6 (T1). Methods: Community-dwelling people with stroke (n = 39) pooled from two studies who were ≥18 years of age were assessed for sedentary behavior at 2 timepoints (T0, T1). Sedentary behavior was measured with the activPAL micro3 following a 7-day wear protocol to obtain mean daily: total sitting time, sitting time accumulated in bouts ≥30 minutes, number of sit-to-stand transitions, and fragmentation index (sit-to-stand transitions/total sitting hours). Paired samples t-tests were used to calculate mean group differences in sedentary behavior metrics between T0 and T1 (α =.05). Cohen’s d was calculated to describe the magnitude of within-person change between T0 and T1. Results: There were no statistically significant within-person differences between T0 and T1 on mean daily sitting time (Cohen’s d= −0.21, p=.19), sitting time accumulated in bouts ≥30 minutes (d= −0.27, p=.11), number of sit-to-stand transitions (d= −0.02, p=.53), or the fragmentation index (d= −0.11, p=.92). Conclusions: Sedentary behavior metrics were stable for over 6 weeks. The number of sit-to-stand transitions per day and the fragmentation index appeared to be the most stable indicators over 6 weeks. Future research should confirm these findings and identify correlates of sedentary behavior among people with stroke.
