Abbreviations: CAD, coronary artery disease; LACS, lacunar stroke; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; OCSP, Oxfordshire Community Stroke Project; PACS, partial anterior circulation stroke; POCS, posterior circulation stroke; SGPALS, Saltin-Grimby Physical Activity Level Scale; TACS, total anterior circulation stroke.Sixty-four participants (4.2%) had a recurrent stroke during the first 6 months. Other conditions after the index hospitalization were previously reported elsewhere.The increaser group had a significant increase in physical activity from 1 week to 6 months after randomization and sustained it at light intensity.The decreaser group had a significant decline in physical activity from 1 week to 6 months after randomization and became inactive.Comparison between the increaser and decreaser groups was conducted using Jonckheere-Terpstra test, Pearson χNot applicable in participants with hemorrhagic stroke (n = 185).One participant had an unclear living arrangement.Others included part-time (n = 68), unemployed (n = 15), volunteer (n = 2), or unknown (n = 21).There were 197 participants with missing educational level data.Cognition was assessed using Montreal Cognitive Assessment, which could not be conducted in 247 participants due to aphasia (n = 26); impairments, including diplopia, hemiparesis, fatigue, or worse general condition (n = 140); unknown reason (n = 60); and administrative or logistics problems (n = 21). Impaired cognition was defined as a score of 1 SD or more below a normative mean after adjusting for age, sex, and educational level.The mRS data were missing in 20 participants, including 5 who withdrew from the study and 15 who were lost to follow-up.The SGPALS data were missing in 167 participants at 1 week, 167 participants at 1 month, 104 participants at 3 months, and 124 participants at 6 months.Two distinct trajectory groups were identified: increaser (720 of 1367 participants [53%]) and decreaser (647 [47%]). The increaser group was characterized by a significant increase in physical activity (mean difference, 0.27; linear slope β
