Despite growing emphasis on home-based rehabilitation following stroke, there remains limited understanding of how to effectively tailor services to individual needs. This study employed concept mapping to explore diverse stakeholder perspectives on adapting home-based rehabilitation to better support the recovery process after stroke. Through this mixed-methods participatory approach, we engaged 89 stakeholders, including stroke survivors, significant others, healthcare professionals, managers, and architects. Participants generated, sorted, and rated statements about what matters most in home-based stroke rehabilitation. A hierarchical cluster analysis was conducted to organize the data into concepts. Five clusters were identified: 1) social support at home and beyond; 2) professional competence; 3) supportive home environment; 4) teamwork and resources; and 5) patient involvement. Patient involvement was rated highest for importance and feasibility, followed by professional competence. Specifically, stakeholders emphasized that rehabilitation should feel meaningful and be tailored to the patient's needs. No generated ideas from the cluster “supportive home environment” were found in the go-zone, and adapting rehabilitation to diverse home environments was recognized as crucial but hard to implement. The findings underscore the need for individualized, context-sensitive approaches and suggest that strengthening professional competence, particularly in navigating diverse environments and engaging support networks, will be essential to translating person-centered principles into everyday rehabilitation practice.
