Determining Device Access for Persons with Physical Disabilities

Time-saving strategies are offered for determining appropriateness of assistive technology devices for persons with physical disabilities in movement and posture. The strategies are based on the principle that even an individual with the most severe involvement has certain controllable movements that can form the foundation for interaction with an assistive technology device. A strategy of direct access is discussed first, emphasizing determination of body parts appropriate for access and identifying access aids for use in conjunction with those body parts. A strategy utilizing scanning is then considered, which involves selection of a desired item from a predetermined configuration. The strategy calls for identifying body parts for use with scanning devices, such as hand/arm, head, knee, or foot, and selective matching of movements with switch placement. Therapeutic position priorities are offered that focus on access positions and stabilization. (Contains 12 references.) (JDD)
