Occupational therapy helps people achieve independence by assisting with the physical and emotional skills they need for work, play, self-care, travel, learning and even relaxation. An occupational therapist's (OT) work includes helping patients develop daily living, leisure and work skills; administering tests; and evaluating patients’ progress, all in tandem with other members of professional health care teams. OTs must have expertise in human anatomy and physiology, and natural, physical and behavioral sciences.
