The occupational therapist works with persons who find it difficult to cope with physical or psychological dysfunction. They help patients improve basic motor functions and reasoning abilities, and compensate for permanent loss of function. Common disabilities seen include stroke, paralysis, brain damage, accidents of hands and arms, arthritis, birth and developmental disabilities, and emotional and mental illness. Occupational therapists assist patients in performing activities of many kinds, ranging from using a computer to caring for daily needs, such as dressing, cooking and eating. Professional practice may be in general hospitals, rehabilitation centers, geriatric homes, out-patient or home-care community programs, and private practice.
