At this Center, we directly interviewed 393 applicants for prostheses, orthotics, or other assistive devices in the last year and assessed their activities of daily living (ADL) using the functional independence measure (FIM). By investigating the relationship between the FIM scores and the prescription of prostheses, orthotics, or other assistive devices, we analyzed ADL in persons prescribed for assistive devices at a rehabilitation counseling center for persons with disabilities. This analysis revealed that there were some ADL patterns on the occasion of preparing medical writings and prescriptions. The FIM scores were totally good with upper or lower limb prostheses. In the case of computer based communication systems, there appeared a specific pattern wherein cognitive ratings except “expression” were good. Some patterns in ADL covering a combination of physical aspects and cognitive ones were found with the lower limb prostheses. ADL patterns were found to be overlapping among seating systems, wheelchairs and powered wheelchairs. Some patterns were seen in active usage for locomotion, some in usage with low physical and cognitive aspects, and others in different usages. From the viewpoint of ADL, some prescription grounds became clear, and it was shown that these grounds could be one of the guidelines used for the indication of assistive devices.
