Occupational Therapists work with people of all ages to enable participation in the occupations that they want and need to do. Underpinned by the professional belief that occupation and wellbeing are linked, Occupational Therapists use occupation as both the goal and main tool of intervention. During the lifespan, occupational participation may be disrupted by ability, a condition, an illness, an injury or a state of mind that can cause a mismatch between the person's ability, the demands of the occupation and/or the environment. Occupational therapists enable participation through modifying occupations, promoting new skills or approaches, adapting environments, or a combination of these.
