Abstract: Purpose: This study describes physical activity levels and factors associated with physical activity at the end of stroke rehabilitation.Methods: Primary stroke survivors were assessed at completion of physical rehabilitation. Outcomes included physical activity (e.g. step count, moderate-vigorous physical activity duration) and sedentary time measured with the Sensewear Armband, gait speed, and cognition. The number of participants meeting physical activity recommendations was calculated. Differences in physical activity were examined between household ambulators (gait speed <0.4 m/s), limited community ambulators (0.4-0.8 m/s), and unlimited community ambulators (>0.8 m/s). The influence of age, cognition, and gait speed on physical activity was determined by multiple regression.Results: Seventy-nine stroke survivors participated. Twenty-one participants achieved 30 min/day of moderate-vigorous physical activity accumulated in 10 min bouts. Unlimited community ambulators took more steps/day (median 4975 vs. 469 limited, 355 household, p < 0.001), had higher moderate-vigorous physical activity (median 74 min/day vs. 22 limited, 31 household, p < 0.001) and lower sedentary time (mean 1105 vs. 1239 limited, 1232 household minutes/day, p < 0.001). Age, gait speed, and cognition predicted 21.3% of the variance in moderate-vigorous physical activity (p = 0.001); adding employment status to the model predicted 57.3% of the variance in step count (p < 0.001).Conclusions: Physical activity is low following stroke and should be a target for treatment, particularly in those with gait speeds ≤0.8 m/s.Implications for rehabilitationSeventy-three percent of stroke survivors performed ≥30 minutes of moderate to vigorous physical activity throughout the day.Twenty-seven percent of stroke survivors accumulated ≥30 minutes of moderate to vigorous physical activity in 10 minute bouts.Despite relatively good physical ability, daily step count was low in this sample.Those with gait speeds ≤0.8 m/s had lower physical activity levels and higher sedentary time.
