The Longitudinal Course of Physical Activity Behavior Poststroke and Its Variation Across Subgroups: The Norwegian Cognitive Impairment After Stroke Study.
Observational study in Physical therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
importanceDespite its importance as a modifiable target poststroke, the longitudinal course of physical activity (PA) is not fully understood.
objectiveThis 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.
designA prospective multicenter cohort study design was used.
settingFollow-up at 3, 18, and 36 months poststroke was community-based.
participantsIn 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.
resultsAverage 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.
conclusionsThe 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.
