Occupational therapy, often abbreviate OT, is the "use of productive or creative activity in the treatment or rehabilitation of physically or emotionally disabled people" (American Heritage Dictionary). A more technical definition is: the use of meaningful occupation to assist people who have difficulty in achieving a healthy and balanced lifestyle and to enable an inclusive society so that all people can participate to their potential in daily occupations of life. Occupational therapists work with a variety of individuals who have difficulty accessing or performing meaningful occupations.
