The goal of this study is to examine the feasibility of delivering an innovative intervention, caregiver-assisted strategy training (CaST), targeting enhancing activity functions in community-dwelling adults after stroke. The main questions it aims to answer are: * Is CaST acceptable to stroke survivors with functional limitations? * Does CaST show positive effects on functional outcomes? Researchers will compare the CaST program to a control education program to investigate the interventional effect size for the selected stroke participants. Participants will: * Receive CAST 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. * Be interviewed once after finishing their intervention.
