Assistive technology service method (ATSM)

Objective. This paper presents the assistive technology service method (ATSM), an evidence-based framework based in part on the WHO's International Classification of Functioning, Disability and Health (ICF), to improve international assistive technology services. Introduction of the Assistive Technology Device Classification (ATDC) into this method provides a connection between devices and function. The Matching Person and Technology (MPT) model demonstrates the impact of contextual factors on achieving satisfaction with and benefit from these services. The ATSM, ATDC and the MPT support the principles of Design for All (DfA) as the most effective and efficient approach for advancing the independence of all people regardless of their age, size or abilities. Main content. It is recognized that assistive technology (AT) benefits individuals with disabilities and that DfA principles move beyond accommodation to inclusion of all people throughout their lifespan and in all contexts. What remains poorly defined is (a) how services to access these applications will be provided, (b) the connection between AT, design principles and functioning; (c) the impact of contextual factors on achieving satisfactory outcomes and (d) the responsibility for use of DfA principles to develop products and provide services. Results. The ATSM, the ATDC and the MPT model embody DfA principles through translation of research into evidence-based practice that benefits all AT stakeholders. The ATSM uses the language of the ICF to establish a cross-disability, interdisciplinary, trans-environmental framework to facili communication for AT practice and education. The ATDC provides a unique connection between AT devices and function as delineated in the ICF. The MPT measures assess the match between technology users and their AT in order to identify training needs, barriers to use, and the desirability of additional supports. Conclusion. The ATSM, ATDC and MPT uphold DfA principles as central to assistive technology services. Implementation of these methods to improve the quality of services will advance access to the products that promote the independence of individuals with disabilities and the people who support them.
