Occupational therapy (OT) is a client-centered health profession concerned with promoting health and well-being through occupation. The primary goal of occupational therapy is to enable people to participate in the activities of everyday life. Occupational therapists achieve this outcome by working with individuals and communities to enhance their ability to engage in the occupations they want to, need to, or are expected to do, or by modifying the occupation or the environment to better support their occupational engagement. The word 'occupation' in this context refers not only to jobs or employment but to all meaningful activities a person performs throughout the day, including self-care, leisure, play, education, and social participation.
The profession is grounded in the belief that engagement in meaningful activities is essential to human health and well-being. Occupational therapists use a holistic approach, considering the physical, psychological, social, and environmental factors that affect a person's ability to function. They work with people across the lifespan, from premature infants in neonatal intensive care units to older adults in skilled nursing facilities. Common areas of practice include rehabilitation after injury or surgery, support for children with developmental delays or disabilities, mental health interventions, ergonomic workplace assessments, and adaptive equipment prescription. The profession draws on knowledge from anatomy, neuroscience, psychology, and sociology to create evidence-based interventions.
Occupational therapy was formally established during World War I, when reconstruction aides used purposeful activities to help wounded soldiers recover both physically and psychologically. The profession has since evolved significantly, expanding into areas such as driver rehabilitation, assistive technology, hand therapy, low vision rehabilitation, and community-based practice. Today, occupational therapists practice in hospitals, outpatient clinics, schools, home health agencies, community programs, and corporate settings. In most countries, entry-level practice requires a master's or doctoral degree, and practitioners must pass a national certification examination and maintain licensure. The profession is guided by theoretical frameworks such as the Model of Human Occupation (MOHO), the Person-Environment-Occupation (PEO) model, and the Occupational Therapy Practice Framework (OTPF) published by the American Occupational Therapy Association.
