The goal of this randomized controlled trial is to examine if involving the caregivers in the strategy training (i.e. caregiver-assisted rehabilitation with strategy training, CAR-ST) works to improve activity functions in community-dwelling adults after stroke. The main questions it aims to answer are: Does CAR-ST and strategy training alone lead to greater improvements in activity performance among stroke survivors relative to the control intervention with education? Does CAR-ST outperform strategy training alone in the efficacy of activity outcomes? Do the activity effects of CAR-ST transfer to the impairment and participation domains of outcomes? Researchers will compare the efficacy of the CAR-ST intervention against strategy training alone or control intervention (education program) to see if caregivers contribute to post-stroke functional improvements. Participants will: * receive CAR-ST, strategy training only, or an education program 1 to 2 sessions per week until finishing 10 sessions. * be assessed clinical outcomes at 4 times: pre-intervention, post-intervention, 3-month, and 6-month follow-up.
