Need For Assistive Technology Research Articles

Mapping gaps and exploring impairment and disability prevalence in South Asian (SAARC) countries: a scoping review

Despite the considerable health and economic burden of disability in the South Asian (SA) region, there is limited evidence of impairments and disabilities prevalence and the need for Assistive Technologies (ATs). This scoping review aims to synthesise the evidence of the impairments and disabilities in SA countries. This review followed Arksey and O’Malley’s methodological framework. EBSCOhost, EMBASE, PubMed, and Web of Science databases were searched for original research articles from SA countries. In this study, impairment and disability refer to functional limitations restricting individuals from performing activities, including visual, hearing, speaking, cognitive, mobility, and self-care difficulties. The review included full-text, English-language articles addressing any impairment and disability, without restrictions on publication date. This review identified 105 articles distributed over the six impairment and disability domains: visual, hearing, mobility, self-care, speaking, and cognitive. Most evidence originated from India (50.5%) and focused on visual impairments (53.3%). The review identified that heterogeneity in methodologies, case identification definitions, and study settings contributed to variations in prevalence estimation and restricted the comparability within and across countries. Besides, the uneven distribution of studies across countries suggests varying inclinations of countries toward specific impairment and disability domains. The review identified variations in prevalence due to differences in methodologies, definitions, and contexts. The review also identified the uneven distribution of studies, limited evidence on ATs, reliance on self-reported data, and lack of nationally representative research. Future research should use standardised case identification and evidence-based approaches to enhance comparability and minimise response biases.

Why robot embodiment matters: questions of disability, race and intersectionality in the design of social robots.

A growing minority of those with disabilities are people of color (POC), with, for example, autism diagnosis rates now higher for children of color than for white children in the USA. This trend underscores the need for assistive technologies, especially socially assistive robots, to be designed with intersectional users in mind. Outside of Japan, most robots are designed with white synthetic skin and able-bodied features, failing to reflect the diverse users they are meant to assist. This paper explores the concept of the "engineering imaginary," the historical and cultural influences that shape these designs, and which tend to limit robot embodiment to white, able-bodied forms. Drawing on work from scholars like Lucy Suchman, Jennifer Rhee, Neda Atanasoski and Kalindi Vora, the paper critiques this engineering bias. A key historical moment in the production of the engineered imaginary of artificial humans is provided by Ovid's myth of Pygmalion and its influence on representations across literature, film, and then robotics. Furthermore, the physicality of the robot, and its role in the production of nonverbal communication (NVC) for more inclusive interaction with humans is explored, seeing these as steps toward what some roboticists are calling Artificial Empathy (AE). Through case studies like Bestic, Bina48, and HuggieBot 3.0, the paper explores what I call the poverty of the engineering imaginary, how current robotics design fails to properly address issues of race, gender, and disability. Ultimately, the paper argues for more inclusive robot designs that accommodate diverse bodies and social dynamics, questioning the pervasive norm of white, able-bodied robotic embodiment.

Health professionals’ experiences and implications of a technology-focused service within a rehabilitation setting

Purpose: Both demand and need for assistive technology (AT) are growing worldwide. However, ensuring an optimal fit between the person and AT is complex. With health professionals often being the “gatekeeper” to AT, it is imperative to understand their experiences of AT. This study was positioned within a sociotechnical space known as “HabITec”, which aims to bring together potential AT users with health professionals and technology developers to enhance the technology-person fit. The current paper reports on health professionals’ experiences of the HabITec Lab (THL), the physical manifestation of HabITec that was piloted in a tertiary hospital for 12-months. Materials and methods: The study used a qualitative descriptive approach to explore the experiences of nine health professionals who referred patients to the lab. Results: Four major themes were identified together with suggestions for the future of THL and HabITec. The themes focused on 1) Balancing service and independence; 2) Capitalising on possibilities and connections; 3) Negotiating multiple mismatches; and 4) Fitting it all together in a coherent service. Conclusions: It was clear that health professionals who referred patients to THL identified a range of benefits associated with it, but barriers to its effectiveness were identified and concerns were raised over health professionals becoming too reliant on the lab. For THL to be sustainably implemented, it appears that a policy-level shift is needed to enable its appropriate resourcing.

Collaborative consensus on assistive technology impacts and outcomes: the GAATO Grand Challenges

ABSTRACT Capturing the outcomes of assistive technology (AT) is essential to know what works and what is needed. People across the globe are working to close the gap of unmet need for AT, and to enable access to quality AT products and services. Inconsistent terminology, measures and a lack of coordinated systems prevent the sharing of knowledge, and the lack of articulated global priorities limit the usefulness of data for policymakers and resource allocation decisions. This paper provides methods of a global “Grand Challenge” project, run by the Global Alliance of Assistive Technology Organizations, and describes the resulting challenges. A multiphase, mixed method approach founded on participatory principles sought to capture multi-country and multi-stakeholder perspectives “from the ground up.” A collaborative consensus method was adapted to document and distil AT challenge data from global regions, to refine this data with global stakeholder organizations, and to publish a shortlist of AT Grand Challenges. The 2022 Grand Challenges in Outcomes and Impact are 1) measuring need, 2) documenting inputs, 3) measuring outcomes, 4) measure impacts, 5) sharing data, and 6) informing policy. The challenge now remains to work together to resolve them.

Unmet Needs and Barriers to Assistive Technology in the Coastal Districts of Karnataka, India.

Assistive Technologies (AT), such as hearing aids, walking aids, prostheses, spectacles, can improve the quality of life and enable many to lead dignified lives. The rapid Assistive Technology Assessment (rATA) tool developed by World Health Organization (WHO) can measure the needs of AT and the barriers to accessing them. This study aimed to measure the unmet needs and the usage of AT via the rATA tool in the coastal state of Karnataka in India. A population-based survey was conducted among a total of 500 households - 250 from Mangalore and 250 from Udupi of Coastal Karnataka. The need for AT was assessed under six domains of activities, including mobility, seeing, hearing, communication, remembering, and self-care. The mean age of study participants was 34.3 years with standard deviation of 21.2 years. 30.6% of the study participants reported the use of assistive products out of which 27.3% used one product and 2% used two products. 89.5% of assistive products were procured from private sector and only 4.1% was obtained from public sector. The level of difficulty in doing any activity increased with age. 301 participants reported out of pocket expenditure for assistive products with mean expenditure of Rs 2226.05 (S. D. 2204) per year. Spectacles, orthoses (spinal) and therapeutic footwear were most common assistive products with unmet need. Our findings highlight the urgent need to mainstream geriatric care policies which address functional difficulties among older people, resolve out-of-pocket spending through public private partnership for assistive technologies.

Use of Assistive Technology for Persons with Psychosocial Disability: Systematic Review.

Assistive technology (AT) refers to assistive products (AP) and associated systems and services that are relevant for function, independence, well-being, and quality of life for individuals with disabilities. There is a high unmet need for AT for persons with disabilities and this is worse for persons with cognitive and mental or psychosocial disabilities (PDs). Further, information and knowledge on AT for PDs is limited. The aim of this review was to explore the pattern of AT use among persons with PDs and its associated socioeconomic and health benefits. The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), and we conducted systematic searches in the 4 databases: PubMed, Embase.com, APA PsycInfo (Ebsco), and Web of Science (Core Collection) with the following index terms: "Assistive Technology," "Self-Help Devices," "Quality of Life," "Activities of Daily Living," "Mental Disorders." We included only AT individuals with PDs can independently use without reliance on a provider. Identified papers were exported to EndNote (Clarivate) and we undertook a narrative synthesis of the included studies. In total, 5 studies were included in the review which reported use of different AT for schizophrenia, bipolar disorder, depression and anxiety disorders. The APs described in the included studies are Palm tungsten T3 handheld computer, MOBUS, personal digital assistant, automated pill cap, weighted chain blankets, and smartphone function. All the AT products identified in the studies were found to be easily usable by individuals with PDs. The APs reported in the included studies have broad impact and influence on social function, productivity, and treatment or management. The studies were heterogeneous and were all conducted in high-income countries. Our study contributes to and strengthens existing evidence on the relevance of AT for PDs and its potential to support socioeconomic participation and health. Although AT has the potential to improve function and participation for individuals with PDs; this review highlights that research on the subject is limited. Further research and health policy changes are needed to improve research and AT service provision for individuals with PDs especially in low-income settings.

Assistive technology usage, unmet needs and barriers to access: a sub-population-based study in India.

Assistive technology (AT) is essential to minimize functional limitations. The current study aimed to estimate the prevalence of needs, met and unmet needs for AT, and barriers to accessing AT among a subnational population in India. This cross-sectional study was conducted in eight districts, representing four zones of India, using the WHO Rapid Assistive Technology Assessment (rATA) tool. The tool was administered by trained staff using read aloud technique. Multi-stage cluster random sampling was used, as well as the probability proportional to size, to select smaller administrative units from the larger ones. In total, 8486 participants were surveyed out of 8964 individuals enumerated with a response rate of 94.6%. The sample prevalence of at least one difficulty was 31.8% (2700), with 6.3% (532) having severe or total difficulties. The sample prevalence for AT need was 27.8% (2357) with an estimated population prevalence of 24.5% (95% CI: 23.5-25.4). Similarly, the sample prevalence of unmet needs was 9.7% (823) with an estimated population unmet needs of 8.0% (95% CI: 7.43-8.60). The unmet needs among persons with severe or total difficulties was 52.3% (278/532), and was higher among females, rural residents, and older persons. Spectacles were the most used products, followed by canes/sticks, tripods, and quadripods. Nearly two-thirds of AT users purchased assistive products at their own expense, particularly from the private sector. The inability to afford AT (36.9%) was the most common barrier. The results show that the need for AT was substantial in the study population, the highest being for seeing difficulties. The unmet needs are higher in females, older population, rural residents, and persons having serious difficulties. While the majority of users have to make out-of-pocket payments to obtain AT, inability to afford and limited availability were the common barriers among those with unmet needs. This research is non-commercial, and was conducted in the interest of public health. The authors have not declared any specific grant for this research.

Development and functional validation of tarsometatarsal prosthesis

Assistive Technology (AT) plays a crucial role in providing aid products, including prostheses to persons with disabilities. Tarsometatarsal (TMT) disarticulation, a type of partial foot amputation, is associated with complex gait disorders. However, there is limited research on the functional impact of TMT prostheses on gait. This study aims to develop and functionally validate a 3D-printed TMT prosthesis using finite element analysis and human motion laboratory studies. A 65-year-old patient with TMT amputation participated. Digital models of the amputated and healthy feet were obtained through 3D scanning. The prosthesis design was created using Fusion 360 software. Finite element analysis validated the prosthesis design. The prosthesis was manufactured using thermofusion printing with a biocompatible thermoplastic elastomer material. Functional validation included walking, running, and the Timed Up and Go test using motion analysis technologies. Finite element analysis demonstrated the structural integrity and safety of the TMT prosthesis during propulsion. The manufacturing process resulted in an adjustable and cost-effective prosthesis. Functional validation revealed improvements in gait quality, symmetry, and spatiotemporal parameters with the prosthesis. Vertical ground reaction forces during walking resembled the normal range, and running performance showed increased symmetry and propulsion velocity. The Timed Up and Go test showed that prostheses reduce time and improve efficiency. The development and functional validation of the 3D-printed TMT prosthesis offer a promising solution for individuals with TMT disarticulation. This approach addresses the need for assistive technologies in low-income countries with limited access to prostheses. Advanced technologies and a patient-centred approach contribute to improving mobility, gait patterns, and overall quality of life for individuals with partial foot amputations. Future research will focus on exploring additional parameters and developing new prostheses to further enhance gait improvements.

Development of BrailleBunny: a device to enhance braille learning

Purpose Braille use has been linked to higher rates of employment, education, financial self-sufficiency, and self-esteem. One area of the world particularly impacted by braille illiteracy is the Philippines. In 2016, Digital Learning for Development and All Children Reading released a “Grand Challenge for Development” that challenged researchers to address the need for assistive technologies to help children with sensory disabilities learn to read in the Philippines. The purpose of this research was to identify technical specifications, and then co-design and test a device that could be used both in developed and developing countries, specifically Canada and the Philippines. Methods An iterative, co-design process was undertaken to develop a prototypical device, BrailleBunny. The extent to which the device fulfilled the design criteria and directions for future development were determined through a series of case studies with 25 end-users. Results The prototypical device requires improvement in financial accessibility, durability and reliability. All other criteria were met. Conclusions Despite identified areas for improvement, the user feedback was positive, with the majority of users identifying that this device could provide transferrable learning to standard-size braille. With improvements, BrailleBunny, could be a valuable tool to increase the uptake of learning braille in the Philippines.

An IoT-Based Multimodal Real-Time Home Control System for the Physically Challenged: Design and Implementation

Physical impairments affect a significant proportion of the global populace, emphasizing the need for assistive technologies to increase the ability of these individuals to perform daily activities autonomously. This study discusses the development and implementation of a multimodal home control system, designed to afford physically challenged individuals greater control over their home environments. This system utilizes the Internet of Things (IoT) for its functionality. The system is primarily based on the utilization of the Amazon Alexa Echo Dot, which facilitates speech-based control, and a sequential clap recognition system, both made possible through an internet connection. These methods are further supplemented by an additional manual switching option, thereby ensuring a diverse range of control methods. The processing core of this system consists of an Arduino Uno and an ESP32 Devkit module. In conjunction with these, a sound detector is employed to discern and process a variety of clap patterns, which is set to function at a predefined threshold. The Amazon Alexa Echo Dot serves as the primary interface for voice commands and real-time information retrieval. Furthermore, an Android smartphone, equipped with the Alexa application, provides alternate interfaces for appliance control, through both soft buttons and voice commands. Based on an analysis of this system, it is suggested that it is not only viable but also effective. Key attributes of the system include rapid response times, aesthetic appeal, secure operation, low energy consumption, and most importantly, increased accessibility for physically disabled individuals.

Testing for acceptance of an assistive social robot for dementia and caregiving

AbstractBackgroundApproximately 5.8 million older adults in the U.S. are living with AD and it is estimated that by 2060, this number is projected to triple. People with AD often require high levels of care and assistance to maintain daily activities. The majority of care provided to a person living with AD or other forms of dementia is from a family caregiver, representing 18.6 billion hours of unpaid care valued at $244 billion. The long duration, time‐intensive nature of caregiving imposes high burdens on caregivers. There is a great need for assistive technologies and innovative solutions for the future of dementia care because of the increasing rise in adults with dementia.MethodA multidisciplinary team of faculty and undergraduate and graduate students was created to design a low‐cost social robot to serve as assistive companions for people with AD. Focus group meetings with caregivers and those with beginning stages of dementia were held, where the team worked in identifying the audience’s needs and robot’s responsibilities. Initial sketches were formulated before being brought to life in Fusion 360 as 3D CAD objects and printed using a 3D printer. Several rounds of iterations of the social robot’s body and user interfaces were created and two final robot designs were tested with undergraduate students (N = 15) for general attitudes of acceptance and feelings of overall experience.ResultResults from our user testing showed that users preferred one design more than another. Users wanted options in their interactions – having the ability to have speech conversation and touch‐screen abilities. Overall, the results from the user testing were positive, and the team is currently working on a final robot design before testing at nursing homes and assisted living facilities.ConclusionEstimated to be less than $300, our socially assistive robot holds promise to help address the disparity issues in the underserved.

Assistive technology: The current perspective in India.

The world, today, recognizes the increasing importance of assistive technology (AT) that can reduce the functional limitations of persons with disabilities, individuals with chronic debilitating diseases, and elders. This indicates that at some point, everyone, either temporary or permanent, will require AT to improve their physical and functional abilities, thus contributing to independent living, social inclusion, and education. Besides this, the need for AT will be growing with a majority from low-middle-income countries. The same is true for India though we are not sure how many people have met a need, and unmet need for AT to date, but the requirement will continue to increase. There is a significant gap between needs and access to AT. Recently, the WHO has led many initiatives related to AT services after the 71st World Health Assembly's resolution in 2018, to improve access to AT for its member states. The UN Sustainable Development Goals (SDGs) have pledged that no one should be left behind irrespective of personal characteristics. India, a ratified member state, needs to align with various initiatives undertaken by the WHO and the UN. Despite many challenges, India needs to formulate evidence-based AT policy, planning within the purview of the healthcare delivery system in collaboration with various government and nongovernment sectors, including industries. This article explores the need, access, and potential challenges associated with AT services in India. Finally, we discussed various initiatives on AT in the country and possible recommendations to improve AT services across.

Healthcare professionals’ perspectives on development of assistive technology using the comprehensive assistive technology model

ABSTRACT The implementation of technology in healthcare shows promising results and provides new opportunities in rehabilitation. However, the adoption of technology into daily care is largely dependent on the acceptance rate of end-users. This study aims to gather information from healthcare professionals on the development of new assistive technology that match users’ needs using the Comprehensive Assistive Technology model. In total 27 healthcare professionals (12 occupational therapists, 8 physiotherapists, 3 nurses, 2 allied health directors, a physician and a speech therapist) attended one of four online focus group discussions. These focus group discussions were structured using a question guide based on three predefined scenarios. Recordings were transcribed and data was analyzed using a thematic analysis (NVivo). Major themes identified in this study were safety, price and usability. Healthcare professionals focused on both functional capabilities of the user, as well as behavioral aspects of usability and attitude toward technology. Furthermore, the need for assistive technology that were catered toward the limitations in activity and user experience, was highlighted extensively. Based on information gathered from healthcare professionals a user-centered approach in development of safe, low-cost devices that maximize both functional outcomes and user acceptance, could potentially increase the adoption of new technology in rehabilitation.

Comprehensive Senior Technology Acceptance Model of Daily Living Assistive Technology for Older Adults With Frailty: Cross-sectional Study.

There are considerable gaps between the need for assistive technologies and the actual adoption of these technologies among older adults, although older adults are among the groups that most need assistive technologies. Consequently, research is needed in this area because older adults' technology acceptance and influencing factors may differ depending on their level of frailty. The objective of this study was to compare frail, prefrail, and robust groups of South Korean adults regarding their behavioral intention to use daily living assistive technologies and the affecting factors-namely, technological context factors, health contexts and abilities, and attitudinal factors-based on a comprehensive senior technology acceptance model. A nationwide sample of 500 older South Korean adults (aged 55-92 years) was analyzed, and multivariate linear regression analyses of the robust, prefrail, and frail groups were performed. The independent and dependent variables consisted of 3 factors based on previous studies. First, technological context factors consisted of gerontechnology self-efficacy, gerontechnology anxiety, and facilitating conditions. Second, health contexts and abilities consisted of self-reported health conditions, cognitive ability, social relationships, psychological function, and physical function. Third and last, attitudinal factors consisted of behavioral intention to use assistive technologies, attitude toward use, perceived usefulness (PU), and perceived ease of use (PEOU). The results of the analyses showed that technological context factors such as gerontechnology self-efficacy, health contexts and abilities such as self-reported health conditions and psychological function, and attitudinal factors such as attitude toward use, PU, and PEOU had significant effects on behavioral intention to use daily living assistive technologies. In particular, gerontechnology self-efficacy had a significant relationship with behavioral intention to use these technologies in the robust (r=0.120; P=.03) and prefrail (r=0.331; P<.001) groups. Psychological function (life satisfaction) had a significant relationship with behavioral intention to use these technologies in the robust group (r=-0.040; P=.02). Self-reported health conditions had a significant relationship with behavioral intention to use these technologies in the prefrail group (r=-0.169; P=.01). Although each group had a different significant relationship with the variables, attitudinal factors such as attitude toward use affected all groups (robust group: r=0.190; P=.03; prefrail group: r=0.235; P=.006; and frail group: r=0.526; P=.002). In addition, PU and PEOU in the attitudinal factors had a significant relationship with behavioral intention to use assistive technologies in the robust (PU: r=0.160; P=.01; and PEOU: r=0.350; P<.001) and prefrail (PU: r=0.265; P<.001; and PEOU: r=0.120; P=.04) groups. This study found that the comprehensive senior technology acceptance model of daily living assistive technologies had different associations according to the frailty group. These findings provided insights into the consideration of interventions with daily living assistive technologies for older adults with varying levels of frailty.

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.

A computer interface controlled by upper limb muscles: effects of a two weeks training on younger and older adults.

As the population worldwide ages, there is a growing need for assistive technology and effective human-machine interfaces to address the wider range of motor disabilities that older adults may experience. Motor disabilities can make it difficult for individuals to perform basic daily tasks, such as getting dressed, preparing meals, or using a computer. The goal of this study was to investigate the effect of two weeks of training with a myoelectric computer interface (MCI) on motor functions in younger and older subjects. Twenty people were recruited in the study: thirteen younger (range: 22-35 years old) and seven older (range: 61-78 years old) subjects. Participants completed six training sessions of about 2 hours each, during which the activity of right and left biceps and trapezius were mapped into a control signal for the cursor of a computer. Results highlighted significant improvements in cursor control, and therefore in muscle coordination, in both groups. All participants with training became faster and more accurate, although people in different age range learned with a different dynamic. Results of the questionnaire on system usability and quality highlighted a general consensus about easiness of use and intuitiveness. These findings suggest that the proposed MCI training can be a powerful tool in the framework of assistive technologies for both younger and older subjects groups. Further research is needed to determine the optimal duration and intensity of MCI training for different age groups and to investigate long-term effects of training on physical and cognitive function.

Listening to the Voice of People with Vision Impairment

Extensive research developed assistive technologies (ATs) to improve mobility for people with vision impairment (PVI). However, a limited number of PVI rely on ATs for mobility. One of the factors contributing to the limited reliability and low acceptance of ATs is the developers’ failure to consider PVI mobility traits from the target group’s perspective. Many developers and researchers proposed solutions based on their knowledge and experiences, where PVI have been excluded from several studies except for limited involvement in testing phases. Accordingly, this study aims to bridge this gap by providing comprehensive information on PVIs’ behaviors, challenges, and requirements for safe and independent outdoor mobility. Therefore, a total of 15 participants with vision impairment were involved in semi-structured interviews and two observation sessions. One key finding highlights the need for AT that complements the conventional cane and overcomes its limitations, not substituting the cane. Moreover, the proposed AT should address instant mobility and future needs simultaneously. Overall, the study contributes to providing comprehensive knowledge on PVI safe and independent mobility traits, which assist AT developers to explore the potential barriers and facilitators of the adoption of ATs among PVIs and leads to develop effective and reliable ATs that meet their needs. For future work, the researchers will develop an AT that complements the conventional cane, supports instant mobility, and enhances cognitive map formation.

Evaluation and intention to use the interactive robotic kitchen system AuRorA in older adults.

BackgroundThe number of older adults in need of care and living at home is increasing in Europe. At the same time, the number of professional caregivers is decreasing. This development reinforces the need for assistive technology to support care recipients in their own homes and promote their independence. One of the main challenges of independent living is the preparation of food. Interactive robots could assist older adults with difficulties performing physically demanding tasks. Within the project AuRorA (full German project title: Wiederverwendbare, interaktive Verhalten für proaktive Roboter im Smart Home), an interactive voice-controlled robot arm was developed as an assistance system in the kitchen.ObjectiveThe aim of the study was to assess how older adults evaluate the AuRorA system and to collect data on actual willingness to use the technology. Older adults were asked to evaluate the system in terms of usefulness, usability, accessibility and intention to use.Material and methodsDue to the ongoing coronavirus disease 2019 (COVID-19) pandemic, the older adults evaluated the system via an online survey. The validated questionnaire Technology Usage Inventory (short: TUI) was used in conjunction with self-developed questionnaires to collect data on study population characteristics.ResultsA total of 106 participants were included in the analysis. The acceptance, usability and usefulness of the system were rated as medium, while the intention to use was rated as low. A significant strong correlation was found between the TUI subscales intention to use and usefulness.ConclusionIt can be assumed that the actual need of the individual participant for such a robotic assistive system had an influence on the evaluation of the system. The perceived usefulness may have been a crucial influence on the intention to use and the overall assessment of the system.Supplementary InformationThe online version of this article (10.1007/s00391-022-02105-8) contains supplementary material, which is available to authorized users.

How digital fabrication technologies within digitalized innovation environments lead to participative aid development

PurposeFacilities such as FabLabs and Makerspaces are characterized by the facilities' wide range of digital fabrication technologies as well as facilities' interdisciplinary user base and collaborative problem solving and product development. These possibilities can also hold great potential for people with disabilities who have a specific need for assistive technology. Since there are no established models of such participatory development processes (PDP) within digitalized innovation environments (DIE), this study intends to provide a comprehensive understanding of these processes along with the influencing factors.Design/methodology/approachThrough a cooperation with a Thalidomide Association, various PDPs were accompanied within a DIE and interviews were conducted with 16 stakeholders involved. Hereby, the perspective of thalidomide-affected people (5) as well as the supporting makers (6) and experts (5) were taken into account. Through a subsequent structured analysis, various dimensions as well as relevant influencing factors could be identified.FindingsIn total, 33 paraphrases could be formed in 8 categories and four dimensions concerning the PDPs investigated. In addition, 17 paraphrases on potentials and challenges could be extracted through generalization.Originality/valueDue to findings' holistic approach, the findings form an empirical basis for further research into this still very young research topic and represent a first step toward theory building. By the applicability of the identified influencing factors an important contribution can be made to the supply of aids and the inclusion of people with disabilities.Peer reviewThe peer review history for this article is available at: https://publons.com/publon 10.1108/JET-01-2022-0013

Restorative rehabilitation robotics to promote function, independence and dignity: users’ perspectives on clinical applications

People with mobility impairments have reported that improving their walking is one of the most important goals of their rehabilitation. Novel robotic technologies using powered exoskeletons for the lower limb could potentially offer efficient and less labour-intensive approaches to rehabilitation with shorter recovery times. To gather users’ and carers’ perspectives of assistive device use to provide information to design personalised and safe mobility rehabilitation technology. Semi-structured interviews were carried out with people with experience of mobility impairments. Iterative data collection was used to gather information about the social phenomena surrounding patient interaction and requirements for assistive devices for mobility impairments. Cycles of continuous data collection and thematic analysis using a theoretical, semantic approach was used to develop key themes within the data. We interviewed eight people: six people with mobility impairments and two carers. We identified five main themes: relationship with assistive technology, requirements for assistive technology, function and goal setting, personal factors to assistive device use and psychosocial factors to assistive device use. There was variability in the importance placed on each theme, particularly in the trade-off between the function and comfort of assistive technology. Patients emphasised the need for assistive technology to be personalised; they reported the ability to stand, control spasticity and involvement in community roles as key goals of their rehabilitation. These results highlight the variation in requirements for assistive technology between people with different mobility impairments; individuals’ experiences are unique and future prototypes need to account for different levels of impairments and personal goals. These findings will also inform the user evaluation stage of assistive device testing. The acceptability of assistive devices is dependent upon a number of factors, including personalisation, comfort and function. Future pilot studies should gather qualitative data to determine the acceptability of actual device use.
