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

A review of innovation strategies and processes to improve access to AT: Looking ahead to open innovation ecosystems

It is essential to understand the strategies and processes which are deployed currently across the Assistive Technology (AT) space toward measuring innovation. The main aim of this paper is to identify functional innovation strategies and processes which are being or can be deployed in the AT space to increase access to AT globally. We conducted a scoping review of innovation strategies and processes in peer-reviewed literature databases and complemented this by identifying case studies demonstrating innovation strategies. The review includes WHO world region, publication year, AT type and a sector analysis against the Systems-Market for Assistive and Related Technologies Framework. We analyzed the case studies and interviews using thematic analysis. We included 91 papers out of 3,127 after review along with 72 case studies. Our results showed that product innovations were more prevalent than provision or supply innovations across papers and case studies. Case studies yielded two themes: open innovation (OI); radical and disruptive innovation. Financial instruments which encourage OI are needed and we recommend pursuing OI for AT innovation. Embedding AT within larger societal missions will be key to success governments and investors need to understand what AT is and their translational socioeconomic value.

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.

Applying market shaping approaches to increase access to assistive technology in low- and middle-income countries

Margaret Savage, Sarah Albala, Frederic Seghers, Rainer Katte, Cynthia Liao, Mathilde Chaudron, Novia Afdhila

Development outcomes are inextricably linked to the health of the marketplace that delivers products and services to people in low- and middle- income countries (LMIC). Shortcomings in the market for assistive technology (AT) contribute to low access in LMIC. Market shaping is aimed at improving a market’s specific outcomes, such as access to high quality, affordable AT, by targeting the root causes of these shortcomings. The paper summarizes the findings of a market and sector analysis that was conducted under the UK aid funded AT2030 programme and aims to discuss how market shaping can help more people gain access to the AT that they need and what are the best mechanisms to unlock markets and commercial opportunity in LMICs.

Development outcomes are inextricably linked to the health of the marketplace that delivers products and services to people in low- and middle-income countries (LMIC). Shortcomings in the market for assistive technology (AT) contribute to low access in LMIC. Market shaping is aimed at improving a market’s specific outcomes, such as access to high quality, affordable AT, by targeting the root causes of these shortcomings. The paper summarizes the findings of market analyses conducted under the UK aid funded AT2030 programme in support of ATscale and aims to discuss how market shaping can help more people gain access to the AT that they need and what are the best mechanisms to unlock markets and commercial opportunity in LMICs. The paper also explores how market shaping for AT markets could be part of a mission-oriented approach AT policy. A mission-oriented approach can help accelerate progress toward a common objective among stakeholders, at country or global level. While market-shaping activities direct the outcomes of the market toward a specific end goal, such as access to quality, affordable products and services, missions are more comprehensive and include other policy interventions and stakeholder collaborations in order to create a robust and sustainable structure.

Assistive technology access in longitudinal datasets: a global review

Jamie Danemayer, Sophie Mitra, Cathy Holloway, Shereen Hussein

A person’s access to assistive products such as hearing aids, wheelchairs, and glasses, is an essential part of their ability to age in a healthy way. But, according to the World Health Organization, a staggering 90% of people who need assistive products worldwide, do not have access to them. In many instances access is limited or simply non-existent. This is often due to assistive products being too expensive, demand outweighing supply, not always being suitable to use in different environments, or even the lack of availability of trained providers. In such circumstances, people are more likely to age ‘unhealthily’ if they do not have access to assistive products that are designed to support their day to day functioning and independence.

Abstract

Assistive technology access in longitudinal datasets: a global review

Functional limitations become more prevalent as populations age, emphasising an increasingly urgent need for assistive technology (AT). Critical to meeting this need trajectory is understanding AT access in older ages. Yet few publications examine this from a longitudinal perspective.

This review aims to identify and collate what data exist globally, seeking all population-based cohorts and repeated cross-sectional surveys through the Maelstrom Research Catalogue (searched May 10, 2022) and the Disability Data Report (published 2022), respectively. Datasets incorporating functional limitations modules and question(s) dedicated to AT, with a wave of data collection since 2009, were included.

Of 81 cohorts and 202 surveys identified, 47 and 62 meet inclusion criteria, respectively. Over 40% of cohorts were drawn from high-income countries which have already experienced significant population ageing. Cohorts often exclude participants based on pre-existing support needs. For surveys, Africa is the most represented region (40%). Globally, 73% of waves were conducted since 2016. 'Use' is the most collected AT access indicator (69% of cohorts and 85% of surveys). Glasses (78%) and hearing aids (77%) are the most represented AT. While gaps in data coverage and representation are significant, collating existing datasets highlights current opportunities for analyses and methods for improving data collection across the sector.

Assistive technology in Korea: Findings from the 2017 National Disability Survey

Jamie Danemayer & Myung-Joon Lim

Korea is a rapidly ageing country, with its population over 65 years old increasing from 5% in 1990 to 17% in 2021. Comparatively, the global population over 65 has increased from 6% in 1990 to 9% in 2019 ]. As populations age and functional difficulties become more prevalent, the importance of assistive technology (AT) provision becomes more pronounced. Disparities in access to AT within a population can indicate inequities in healthy aging trajectories that will widen as the overall population ages, if clusters of limited access are not identified and addressed.

Abstract

Assistive technology in Korea: Findings from the 2017 National Disability Survey

Purpose

Explicitly monitoring the need, use and satisfaction of assistive product (AP) provision is essential to support population health and healthy longevity in ageing/aged countries, like Korea. We present findings from the 2017 Korea National Disability Survey (NDS) on AP access and compare them to international averages, introducing Korea’s data into the wider coherence of global AP research.

Materials and methods

Using data from Korea’s 2017 NDS, surveying 91,405 individuals, we extracted and calculated AP access indicators, including needing, having, using and being satisfied with 76 unique APs, by functional difficulty and product type. We compared satisfaction and unmet need between the National Health Insurance System (NHIS) and alternative provision services.

Results

Prosthetics and orthotics had high rates of under-met need, and lower satisfaction rates, from 46.9% to 80.9%. Mobility APs overall had higher rates of under-met need. There was either low (<5%) or no reported need for most digital/technical APs. Among main products, those provided through the NHIS had lower unmet need (26.4%) than through alternative providers (63.1%), though satisfaction rates were similar (p < .001).

Conclusions

The Korean survey findings align with global averages calculated in the Global Report on Assistive Technology. Low reported needs for certain APs may reflect low awareness about how these products could benefit users, emphasizing the importance of data collection at each stage of the AP provision process. Recommendations to expand access to APs are given for people, personnel, provision, products, and policy.

Implications for rehabilitation

  • Access to assistive products (APs) is an essential part of physical and occupational therapy services and rehabilitation. Monitoring population-level data on disability and AP access can inform policymakers about a key aspect of population health and healthy ageing, and demonstrate the need to expand access by including APs and associated services in primary/universal healthcare packages.
  • Stratifying findings about AP access by type of functional difficulty and further by specific device helps identify the populations for whom needs are not being met. These domain-level and device-level indicators inform efforts to support specific groups within the population of people with disabilities, which has implications for how rehabilitation services are provisioned, targeted and made more accessible.
