Background: Assistive Technology (AT) refers to “assistive products and related systems and services developed for people to maintain or improve functioning and thereby to promote well-being”. Improving the process of design and creation of assistive products is an important step towards strengthening AT provision. Purpose: (1) to present a framework for designing and creating Low-Cost AT; (2) to display the preliminary results and evidence derived from applying the framework. Methodology: First, an evidence-based process was applied to develop and conceptualize the framework. Then, a pilot project to validate the framework was carried out. The sample was formed by 11 people with disabilities. The measure instruments were specific questionnaire, several forms of the Matching Person-Technology model, the Psychosocial Impact of Assistive Device Scale, and a tool to assess the usability and universal design of AT. Results: The framework integrates three phases: Identification (Design), Creation (Making the prototype), and Implementation (Outcome Measures), based on the principles of Design Thinking, and with a user-centered perspective. The preliminary results showed the coherence of the entire process and its applicability. The matching between person and device was high, representing the importance of involving the user in the design and selection of AT. Conclusions: The framework is a guide for professionals and users to apply a Low-Cost and Do-It-Yourself perspective to the provision of AT. It highlights the importance of monitoring the entire procedure and measuring the effects, by applying the outcome measures.

This paper presents developing Alber principle for machine supporting wheelchair in climbing stairs. The designed machine can support wheelchair and disabled people with total weight 80 kg climb up and down most of stairs and with speed 10-15 stairs per minute. Moving wheelchair and disabled people need assistant person who will hold handle and control the machine. The machine is designed with a simple structure, manufactured with low cost and simple controlling. Therefore the machine can be upgraded and manufactured in future.

This paper describes the user interface design, and subsequent usability evaluation of the EU FP6 funded Easyline+ project, which involved the development of ambient assistive technology to support elderly and disabled people in their interaction with kitchen appliances. During this process, established usability design guidelines and principles were considered. The authors’ analysis of the applicability of these has led to the development of a new set of principles, specifically for the design of ambient computer systems. This set of principles is referred to as SCUFF, an acronym for simplicity, consistency, universality, flexibility and familiarity. These evaluations suggest that adoption of the SCUFF principles was successful for the Easyline+ project, and that they can be used for other ambient technology projects, either as complementary to, or as an alternative to more generic and partially relevant principles.

This paper describes a new fabrication process for making low-cost transradial sockets using recyclable plastic soda bottles. Easy, fast, and inexpensive to fabricate, the resulting socket can be used as a temporary device for stump care. Multiple sockets can be made and individually incorporated with various terminal devices for light-duty self-care or functional activities, such as feeding, showering, typing, swimming, or gardening. The formed socket is lightweight and also suitable for use with a cosmetic passive hand prosthesis. This process has been developed as a potential cost-effective assistive technology appropriate for individuals with transradial amputation in resource-limited countries.

A Doença de Parkinson (DP) é uma síndrome neurodegenerativa que se caracteriza essencialmente por déficts motores, incluindo prejuízos nas habilidades manuais, o que interferem no desempenho das atividades cotidianas. Os terapeutas ocupacionais utilizam recursos de Tecnologia Assistiva (TA) para favorecer a autonomia e independência. O uso de TA impressa em 3D é um recurso inovador e possibilita a personalização com baixo custo. O objetivo desta pesquisa é descrever o processo de avaliação e desenvolvimento de produtos de TA em 3D para pessoas com déficit de função manual por Doença de Parkinson. Trata-se de um estudo observacional, descritivo, de corte transversal, do tipo relato de caso. A paciente estudada tinha 61 anos, diagnosticada há 3 anos e era auxiliar administrativa. Apresentava déficit nas habilidades manuais de leve à moderado e as atividades com maior prejuízos funcionais foram: usar colher, varrer casa, usar escova de dentes e manusear a agulha de crochê. A pontuação média de desempenho foi 6,0 e de satisfação 4,5, de acordo com a Medida Canadense de Desempenho Ocupacional, para as atividades citadas. Após escaneamento do membro superior foi impressa em 3D uma adaptação universal para favorecer as atividades do uso da colher, da escova de dente e da agulha de crochê. O recurso proporcionou um melhor desempenho nas atividades e a paciente destacou satisfação com o uso do recurso e serviço utilizados. Dessa forma, A TA impressa em 3D pode ser um recurso eficaz e se faz necessário ampliar os estudos na área. AbstractParkinson's disease (PD) is a neurodegenerative syndrome that is essentially characterized by motor deficit, including impairments in manual skills, which may interfere with the performance of daily activities. Occupational therapists use Assistive Technology (AT) resources to promote autonomy and independence. The use of AT printed in 3D is a resourse innovative and possibility of customization and low cost. The objective of the research is to describe the process of evaluating and developing 3D AT products for people with Parkinson's disease manual function deficit. This is an observational, descriptive, cross-sectional study of the case report type. The patient studied was 61 years old, diagnosed 3 years ago and was an administrative assistant. There were deficits in the manual skills of mild to moderate and the activities with the greatest functional losses were: to use spoon, to sweep house, to use toothbrush, and to handle the crochet needle. The average performance score was 6.0 and satisfaction 4.5, According to the Canadia Measure of Occupational Performance, for the above activities. After scanning the upper limb was printed in 3D universal adaptation with main focus on favoring the activities of using the spoon, toothbrush and crochet needle. The resource favored a better performance in the activities and the patient reported satisfaction with the use of the resource and service used. Assistive technology printed in 3D can be an effective resource, it is necessary to expand the studies in the area.Keywords: Parkinson's disease; Self-Help Devices; Occupational Therapy. Resumen La enfermedad de Parkinson (DP) es un síndrome neurodegenerativo que se caracteriza esencialmente por déficits motores, incluyendo perjuicios en las habilidades manuales, lo que puede interferir en el desempeño de las actividades cotidianas.

An estimated 80% of the world's disabled people live in low-income countries. The majority of them are poor and do not have access to basic services, including rehabilitation facilities. Motivation is an international organization working in low-income countries to improve opportunities for disabled people by positively influencing their physical, social, and economic situations to enable their full participation in society. Providing good-quality, low-cost, ergonomic wheelchairs in low-income countries is extremely challenging. These complex issues are best addressed by establishing comprehensive services with trained staff and a range of innovative product solutions.
