Occupational therapy is a healthcare profession. It involves the use of assessment and intervention to develop, recover, or maintain the meaningful activities, or occupations, of individuals, groups, or communities. Occupational therapists and occupational therapy assistants focus on the things you want and need to do in your daily life. Occupational therapy intervention uses everyday life activities (occupations) to promote health, well-being, and your ability to participate in the important activities in your life.
