An occupational therapist works with a client to help them achieve a fulfilled and satisfied state in life through the use of "purposeful activity or interventions designed to achieve functional outcomes which promote health, prevent injury or disability and which develop, improve, sustain or restore the highest possible level of independence." A practical definition for OT can also be illustrated with the use of models such as the Occupational Performance Model (Australia), known as the OPM(A). At the core of this approach is the ideology that occupational therapists are concerned with the occupations of people and how these contribute to health. Specifically it is a person's occupational performance that influences their health and personal satisfaction of their individual needs. The OPM(A) is constructed on the following definition of Occupational Performance:
The ability to perceive, desire, recall, plan and carry out roles, routines, tasks and sub-tasks for the purpose of self-maintenance, productivity, leisure and rest in response to demands of the internal and/or external environment.
It can be seen that occupational performance, the roles it creates for a client, and the areas it can encompass are so far-reaching that an occupational therapist can work with a wide range of clients of various limitations who are being cared for in an array of settings. Occupational therapy is about helping people do the day-to-day tasks that "occupy" their time, sustain themselves, and enable them to contribute to the wider community. It is these opportunities to "do", which occupational therapy provides, that prove important and meaningful to the health of people.
Occupational therapists (OTs) help people of all ages to improve their ability to perform tasks in their daily living and working environments. They work with individuals who have conditions that are mentally, physically, developmentally, socially or emotionally disabling. They also help them to develop, recover, or maintain daily living and work skills. Occupational therapists help clients not only to improve their basic motor functions and reasoning abilities, but also to compensate for permanent loss of function. Occupational therapists assist clients in performing activities of all types, ranging from using a computer to caring for daily needs such as dressing, cooking, and eating. Physical exercises may be used to increase strength and dexterity, while other activities may be chosen to improve visual acuity and the ability to discern patterns. For example, a client with short-term memory loss might be encouraged to make lists to aid recall, and a person with coordination problems might be assigned exercises to improve hand-eye coordination. Occupational therapists also use computer programs to help clients improve decision-making, abstract-reasoning, problem solving, and perceptual skills, as well as memory, sequencing, and coordination —- all of which are important for independent living. Occupational therapists are often skilled in psychological strategies such as cognitive behavioral therapy and Acceptance and Commitment Therapy, and may use cognitive therapy especially when introducing people to new strategies for carrying out daily activities such as activity pacing or using effective communication strategies.
