During the process of community integration, individuals with acquired brain injury may experience difficulties in all areas of occupational performance including self-care, home management, community access, leisure, social activities and vocational pursuits. Community based rehabilitation services provide opportunities to minimise such difficulties by working with clients as they engage in meaningful real-life context-based occupations. The therapeutic use of occupation is at the core of occupational therapy practice. We reflect on the nature and principles of occupation and highlight particular benefits for facilitating community integration after brain injury. This is illustrated using the example of executive dysfunction. Several challenges for the occupational therapy profession arise from the shift in focus from hospital to community based rehabilitation, and the need for further research on community integration after brain injury from an occupational perspective is recognised.
