Sedentary behavior patterns over 6 weeks among ambulatory people with stroke.

: To describe patterns of sedentary behavior over 6 weeks among ambulatory people with subacute and chronic stroke.: Observational longitudinal study with assessments at baseline (T0) and week 6 (T1).: 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 -tests were used to calculate mean group differences in sedentary behavior metrics between T0 and T1 (α =.05). Cohen's was calculated to describe the magnitude of within-person change between T0 and T1.: There were no statistically significant within-person differences between T0 and T1 on mean daily sitting time (Cohen's = -0.21, =.19), sitting time accumulated in bouts ≥30 minutes (= -0.27, =.11), number of sit-to-stand transitions (= -0.02, =.53), or the fragmentation index (= -0.11, =.92).: 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.
