Background: Sedentary time is high and physical activity low following stroke. There is limited understanding of factors which promote greater activity, and consequently improve function and reduce cardiovascular risk. We examined whether change in environment (hospital/home) influenced the time spent sitting, upright and walking, as well as factors predicting any change.

Methods: 34 participants with stroke were recruited consecutively from 2 rehabilitation units. An activity monitor (ActivPAL3) was worn for 7 days (24 hours/day) at 2 time points: final week in hospital, and first week home. Other measures included mood (HADS), fatigue (FAS) and physical function (gait speed, 6 min walk). Linear mixed models (adjusted for waking hours) were performed with activity time as the outcome and environment as the exposure.

Results: Activity data was available at both time points for 32 (94%) participants (mean age 68 [SD 13] years, 53% male). At home participants spent 45 fewer minutes sitting (95% CI -84,-6 p=0.023), 45 more minutes upright (95% CI 6 ,85 p=0.024), 12 minutes more walking (95% CI 5-19 p=0.001) and completed 712 additional steps per day (95% CI 188 ,1236 p=0.008), compared to the final week in hospital. Better mood prior to discharge predicted differences for all activity outcomes, with the addition of lower fatigue for better walking outcomes (p≤0.05).

Conclusions: Change in environment from hospital to home reduced sitting time and increased time spent in physical activity and daily step count. The environment may be a modifiable factor which clinicians can target to reduce sitting time and promote increases in physical activity.
