Importance:
Despite its importance as a modifiable target poststroke, the longitudinal course of physical activity (PA) is not fully understood.
Objective:
This study aimed to describe the course of poststroke PA behavior from 3 to 36 months and identify subgroups with different PA patterns using multi-trajectory modeling.
Design:
A prospective multicenter cohort study design was used.
Setting:
Follow-up at 3, 18, and 36 months poststroke was community-based.
Participants:
In total, 277 individuals (age = 70.1 [SD = 10.9]; 116 [41.9%] female) with primarily mild strokes were included. Participants provided at least 2 follow-up periods with accelerometer data each lasting at least 3 consecutive days.
Main Outcomes And Measures:
At each follow-up, daily estimates of upright time, time spent in light physical activity (LPA), time spent in moderate physical activity (MPA), step count, and the number of sit-to-stand transitions were measured.
Results:
Average daily upright time declined by -7.4 min (95% CI = -10.09 to 4.64), and average daily step count declined by -132 steps (95% CI = -176 to -88) each year. Four distinct groups of individuals with different characteristics were identified, following a similar developmental course across PA dimensions over time: one-fourth of the participants (25.6%) were characterized by stable low PA estimates and a tendency to decline over time. Two groups, making up 32.4% and 20.8% of the sample, were characterized by intermediate levels of LPA and MPA, with differing levels of sit-to-stand transitions; and 1 group (21.2% of participants) was characterized by stable high PA duration estimates over time.
Conclusions:
The overall course of PA poststroke was characterized by a modest decrease over 3 years. Differing PA trajectory groups characterized by different demographic and clinical features highlight the diverse needs for supporting people living with stroke in becoming more active.
Relevance:
Findings may help clinicians identify subgroups of people with stroke who need extended professional follow-up in long-term rehabilitation.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling...
