Abstract

Repair strategies for assistive technology in low resource settings

Abstract

Purpose

To investigate the practices of repair that exist for users of mobility assistive products in low resource settings, as well as the psychosocial impact that the repair, or non-repair, of these devices has on users’ lives.

Materials and Methods

This article collates data on repair practices and the responses from participants on the topic of repair from studies conducted by the authors across four different low resource settings in Kenya, Uganda, Sierra Leone, and Indonesia. This data was then analyzed to identify the common themes found across geographies.

Results

Three major models of repair practice emerged from the data: “Individual or Informal Repair in the Community”; “Local Initiatives”; and “Specialist AT Workshop Repair”. Additionally, the wider impact on the participants’ lives of “Problems & Concerns with Repair”; “Experiences of Breakages & Frequencies of Repair” and the “Impact of Broken Devices” are explored.

Conclusions

The results of this analysis demonstrate the paramount importance of community-based repair of devices, and how despite this importance, repair is often overlooked in the planning and design of assistive products and services. There is a need to further incorporate and support these informal contributions as part of the formal provision systems of assistive device.

Developing inclusive and resilient systems: COVID-19 and assistive technology

Emma M. Smith, Malcolm MacLachlan, Ikenna D. Ebuenyi, Catherine Holloway & Victoria Austin

While the inadequacies of our existing assistive technology systems, policies, and services have been highlighted by the acute and rapidly changing nature of the COVID-19 pandemic, these failures are also present and important during non-crisis times. Each of these actions, taken together, will not only address needs for more robust and resilient systems for future crises, but also the day-to-day needs of all assistive technology users. We have a responsibility as a global community, and within our respective countries, to address these inadequacies now to ensure an inclusive future.

Abstract

Developing inclusive and resilient systems: COVID-19 and assistive technology

Assistive technology is a critical component of maintaining health, wellbeing, and the realization of rights for persons with disabilities. Assistive technologies, and their associated services, are also paramount to ensuring individuals with functional limitations have access to important health and social service information, particularly during a pandemic where they may be at higher risk than the general population. Social isolation and physical distancing have further marginalized many within this population. We have an opportunity to learn from the COVID-19response to develop more inclusive and resilient systems that will serve people with disabilities more effectively in the future. In this Current Issues piece, we present a starting point for discussion, based on our experiences working to promote access to assistive technologies through inclusive and sustainable systems and policies.

Additive manufacturing techniques for smart prosthetic liners

B Oldfrey, A Tchorzewska, R Jackson, M Croysdale, R Loureiro, C Holloway, M Miodownik

Elastomeric liners are commonly worn between socket and limb by prosthetic wearers. This is due to their superior skin adhesion, load distribution and their ability to form a seal. Laboratory tests suggest that elastomeric liners allow reduced shear stress on the skin and give a higher cushioning effect on bony prominences, since they are soft in compression, and similar to biological tissues [1]. However, they also increase perspiration reducing hygiene and increasing skin irritations. Prosthetic users in general face a myriad of dermatological problems associated with lower limb prosthesis such as ulcers, cysts, and contact dermatitis, which are exacerbated by the closed environment of a fitted socket where perspiration is trapped and bacteria can proliferate [2].

Abstract

Additive manufacturing techniques for smart prosthetic liners

Elastomeric liners are commonly worn between the prosthetic socket and the limb. A number of improvements to the state of the art of liner technology are required to address outstanding problems. A liner that conforms to the residuum more accurately, may improve the skin health at the stump-socket interface. Previous work has shown that for effective thermal management of the socket environment, an active heat removal system is required, yet this is not available. Volume tracking of the stump could be used as a diagnostic tool for looking at the changes that occur across the day for all users, which depend on activity level, position, and the interaction forces of the prosthetic socket with the limb. We believe that it would be advantageous to embed these devices into a smart liner, which could be replaced and repaired more easily than the highly costly and labour-intensive custom-made socket. This paper presents the work to develop these capabilities in soft material technology, with: the development of a printable nanocomposite stretch sensor system; a low-cost digital method for casting bespoke prosthetic liners; a liner with an embedded stretch sensor for growth / volume tracking; a model liner with an embedded active cooling system.

Critical Junctures in Assistive Technology and Disability Inclusion

It is clear from the events of the last 18 months that while technology has a huge potential for transforming the way we live and work, the entire ecosystem—from manufacturing to the supply chain—is vulnerable to the vagaries of that ecosystem, as well as having the potential to exacerbate new and existing inequalities [1]. Nowhere has this been more apparent than in the lives of people with disabilities, who make up around 15% of the world’s population and already face barriers to accessing education, employment, healthcare and other services [2]. Some of these barriers are a result of unequal access and opportunities. However, there is a growing movement to better understand how assistive technology systems and services can be designed to enable more robust and equitable access for all. As part of this growing movement, the Paralympic Games in Tokyo this autumn saw the launch of a new global campaign to transform the lives of the world’s 1.2 bn persons with disabilities: the ‘WeThe15’ campaign reached more than 4.5 billion people through its marketing and stands ready to be the biggest of its kind in history. Next year, the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF), AT scale and GDI Hub will publish the first World Report on Access to Assistive Technology, which will include research from the £20 million, UK Aid funded, GDI Hub-led, programme, AT2030. Ahead of that, in this Special Issue, we focus on how some events and situations—as diverse as the coronavirus pandemic and the Paralympics—can act as ‘critical junctures’ that can enable a rethink of the status quo to facilitate and promote change.

End Superscript

Access to information on digital platforms not only facilitates education, employment, entertainment, social interaction but also facilitates critical governmental services, ecommerce, healthcare services and entrepreneurship [1]. Article 9 of United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) enforces its signatories to commit to provide full accessibility to every citizen of the nation [2]. This has helped to spearhead accessibility directives such as the European Accessibility Act [3] that aims to improve the functioning of markets for accessible products and services. Such directives contribute to ensure that mainstream digital technologies (smartphones, computers etc.) are accessible for everyone and without being socially remarkable, they are able to assist in daily living. Additionally, there is evidence that improving access in mainstream technologies improves product experience and usability for everyone [4]. However, mainstream access has not been fully realized, leading to inferior opportunities for people with disabilities, a disparity which is more prominent in lower and middle-income countries [5].

Abstract

Could Assistive Technology Provision Models Help Pave the Way for More Environmentally Sustainable Models of Product Design, Manufacture and Service in a Post-COVID World?

From multiple studies conducted through the FCDO AT2030 Programme, as well as key literature, we examine whether Assistive Technology (AT) provision models could look towards more sustainable approaches, and by doing this benefit not only the environment, but also address the problems that the current provision systems have. We show the intrinsic links between disability inclusion and the climate crisis, and the particular vulnerability people with disabilities face in its wake. In particular, we discuss how localised circular models of production could be beneficial, facilitating context driven solutions and much needed service elements such as repair and maintenance. Key discussion areas include systems approaches, digital fabrication, repair and reuse, and material recovery. Finally, we look at what needs be done in order to enable these approaches to be implemented. In conclusion, we find that there are distinct parallels between what AT provision models require to improve equitable reliable access, and strategies that could reduce environmental impact and bring economic benefit to local communities. This could allow future AT ecosystems to be key demonstrators of circular models, however further exploration of these ideas is required to make sense of the correct next steps. What is key in all respects, moving forward, is aligning AT provision with sustainability interventions.
