PurposeThis contribution shows perspectives of experts from different disciplines and professional backgrounds in order to elaborate on maker approaches such as do-it-yourself prosthetics and collaborative tools. As a result, aspects of open source practices related to medical and assistive technologies will be critically reflected upon. In addition, implications of heterogeneous interests, economic implications and everyday achievements of social material assemblages produced through participatory design research are discussed.Design/methodology/approachIn order to address an interdisciplinary and transdisciplinary perspective on the relationships between body (differences) and technology, it is necessary to bring together studies from both Science and Technology Studies (STS) and crip technoscience as well as approaches from participatory design research and practice. This challenge was addressed by a roundtable organized as part of the third network meeting of the Dis/Ability and Digital Media Research Network on 16 September 2020.FindingsAgainst the backdrop of “crip technoscience” DIY and collaborative open source practices are not only understood as valuable alternatives to standardized medical prosthetics and assistive devices. These bottom-up approaches which draw from the expert knowledge of disabled users (Hamraie and Fritsch, 2019) also facilitate devices that defy categories such as “prosthetic” or “medical aid” not only aesthetically but semantically, too.Originality/valueThe Network Dis/Abilities and Digital Media intends to integrate media and technology studies with disability studies on a theoretical level. This round table discussion delivers proof of how – on the practical level – technology and dis/ability need to be thought of as relational and co-constitutive (Mills and Sterne, 2017).

Background. Today, the development and widespread use of digital technologies in medicine is considered as one of the most promising mechanisms for optimizing costs and improving the efficiency of healthcare and the quality of life of the aging society.Objective: to study the experience of using telemedicine technologies for providing medical care in the health systems of different countries, including the Russian Federation.Material and methods. To obtain the necessary information, an overview of the most relevant studies published in Medscape, PubMed/ MEDLINE, ScienceDirect, Scopus, eLibrary, CyberLeninka databases, World Health Organization repository and open sources from Google and Yandex search, as well as relevant regulatory documents was carried out.Results. The experience of using telemedicine technologies for medical care in healthcare systems of different countries, including Russia, presented in the article, demonstrates both the advantages of these technologies, and the limitations for their use in healthcare.Conclusion. Despite all the undisputed advantages of telemedicine technologies, their development should not become an end in itself. The expediency of their use in each specific case of providing medical care and exclusively as another, additional tool to improve the quality and accessibility of medical care should be considered.

In this paper, an experimental evaluation of an active upper-limb exoskeleton, where 12 subjects perform an overhead industrial task with and without the exoskeleton, is presented. The experimental laboratory test has been carried out to analyze the advantages of wearing the exoskeleton to carry out repetitive industrial tasks, assessing whether the proposed device reduces metabolic parameters and the muscular strain. The set of metrics to assess the effects of the exoskeleton included biomechanical parameters, such as electromyographic signals, and metabolic parameters, such as heart rate, heart rate variability, respiratory frequency, tidal volume, ventilation and oxygen consumption. The results show that the developed active upper-limb exoskeleton can reduce cardiorespiratory responses and muscular activity. In addition, statistical data analysis shows significant differences in oxygen consumption, heart rate and effort supported by muscles between conditions (when handling a load of 1.7 kg with and without the exoskeleton). It is observed that, wearing the exoskeleton reduces oxygen consumption by more than 24%, the heart rate decreases by 14%, and muscle activity is reduced by almost 37% in triceps and up to 64% in biceps compare to no wearing. Based on these results, the presented active upper-limb exoskeleton could be potentially useful to reduce muscular strain and fatigue in repetitive overhead tasks.

This paper explores the potential for using a voice interface to improve access to reading materials for students who are blind. Students who are blind face many barriers to higher education, including access to reading materials due to graphical library database interfaces that are often not designed to be accessible. This paper reports findings from semi-structured, open-ended interviews with 25 academic librarians with experience serving students who are blind. Themes emerging from the interviews included challenges in developing a voice interface for accessing library materials in terms of the academic library context, user behavior, and voice interface technology. For the academic library context, the challenges included cost, technical expertise, and spatial limitations. For user behavior, the challenges involved developing complex search queries using a voice interface. For voice interface technology, librarians identified the lack of interconnectivity among library databases, the difficulty in presenting search query results via voice, and the potential for bias as challenges. These findings demonstrate broad interest in such a voice interface among academic librarians and provide guideposts for steering the design of such a voice interface.

Introduction: In dementia care, locating technologies are a type of assistive technology that hold the potential to improve the quality of life of persons with dementia and their care partners by assisting in the management of spatial orientation impairments and wandering. Although many products are commercially available, their adoption remains low. To better understand how to promote their adoption, we examined user experience and clinical effectiveness resulting from product use and explored barriers to their adoption. Methods: In a first user experience study, a prototype locating technology was tested for four weeks by 17 dyads composed of persons with dementia and their care partners. In a second user experience study, two similar commercially available locating technologies were tested for four weeks each by another 17 dyads. User experience was examined with ratings of product usability, product functions and product features. Clinical effectiveness, frequency of use, purchase willingness, and product satisfaction were assessed with various scales. In a third qualitative focus group interview study with 22 interdisciplinary professional stakeholders, we explored views on the barriers to their adoption, as well as views on services and information dissemination strategies. Results: In the first study, the prototype was rated fairly in terms of usability, product functions and product features. However, usability ratings significantly decreased after four weeks. In the second study, ratings of usability, as well as of several product functions and product features were significantly more favourable for one of the two tested commercial products. Clinical effectiveness was not found in either study. In the third study, the main adoption barriers were based on unclear benefits and ethical concerns, as well as limitations in awareness, technology, product characteristics, and capital investments. Key services and information dissemination strategies centred on digital autonomy support, emergency support, information dissemination actors, product acquisition, and product advertising. Discussion: Results from both user experience studies indicate that focusing on specific product functions and features might substantially improve user experience. This might translate to measurable clinical effectiveness and higher adoption rates. Results from our qualitative study indicate that not only product characteristics and the technology itself impact adoption. Indeed, focusing on services and information dissemination strategies around products warrants closer attention as they might markedly improve adoption., Einleitung: Ortungssysteme in der Demenzversorgung gelten als eine vielversprechende Art von assistierender Technologie, um die Lebensqualität von Menschen mit Demenz und ihren Pflegepartnern zu verbessern, indem sie dabei helfen räumliche Orientierungsstörungen und Wanderungen zu bewältigen. Ihre Verwendung bleibt jedoch trotz der Verfügbarkeit vieler kom-merzieller Produkte gering. Um besser zu verstehen, wie ihre Verwendung gefördert werden kann, haben wir die Nutzererfahrung und klinische Wirksamkeit, die sich aus der Produktnutzung ergeben sowie die Barrieren für ihre Einführung untersucht. Methoden: In einer ersten Nutzererfahrungsstudie wurde ein Prototyp Ortungssystem vier Wo-chen lang von 17 Dyaden bestehend aus Menschen mit Demenz und ihren Pflegepartnern ge-testet. In einer zweiten Nutzererfahrungsstudie wurden zwei ähnliche kommerziell erhältliche Or-tungssysteme jeweils vier Wochen lang von weiteren 17 Dyaden getestet. Die Nutzererfahrung wurde mit Bewertungen der Benutzerfreundlichkeit, Produktfunktionen und Produkteigenschaften untersucht. Klinische Wirksamkeit, Nutzungshäufigkeit, Kaufbereitschaft und Produktzufrieden-heit wurden mit verschiedenen Skalen bewertet. In einer dritten qualitativen Fokusgruppeninter-viewstudie mit 22 interdisziplinären professionellen Stakeholdern untersuchten wir Ansichten zu den Barrieren für ihre Verwendung sowie zu Dienstleistungen und Strategien zur Informationsverbreitung. Ergebnisse: In der ersten Studie waren die Bewertungen der Benutzerfreundlichkeit, Produkt-funktionen und Produkteigenschaften mittelmäßig. Die Bewertung der Benutzerfreundlichkeit ging jedoch nach vier Wochen deutlich zurück. In der zweiten Studie fielen die Bewertungen der Benutzerfreundlichkeit sowie einiger Produktfunktionen und Produkteigenschaften bei einem der beiden getesteten Produkte deutlich besser aus. Klinische Wirksamkeit wurde in keiner der Studien gefunden. In der dritten Studie konzentrierten sich die wichtigsten Einführungsbarrieren auf unklare Vorteile und ethische Bedenken sowie auf bewusstseins-, technologisch-, produktmerkmal- und kapitalinvestitionsbasierte Einschränkungen. Dienstleistungen und Strategien zur Informationsverbreitung konzentrierten sich auf Unterstützung von digitaler Autonomie, Notfallunterstützung, Akteure der Informationsverbreitung, Produktakquisition und Produktwerbung. Diskussion: Die Ergebnisse beider Studien zur Nutzererfahrung zeigen, dass die Nutzererfah-rung durch die Optimierung bestimmter Produktfunktionen und Produkteigenschaften erheblich verbessert werden kann. Dies könnte zu einer messbaren klinischen Wirksamkeit und höheren Verwendung führen. Die Ergebnisse unserer qualitativen Studie zeigen, dass die Verwendung durch mehr als die Produktemerkmale und die Technologie selbst bestimmt wird. Deshalb ist eine gezielte Fokussierung auf Dienstleistungen und Strategien zur Informationsverbreitung rund um Ortungssysteme notwendig, da sie die Verwendung deutlich verbessern könnte.

Background Assistive technologies have the potential to facilitate everyday life of people with dementia and their families. Close collaboration with affected people and interdisciplinary research are essential to understand and address the needs of prospective users. In this study, we present the results of the evaluation of such an assistive system prototype. Aims Challenges from the patient and caregiver side, technical and design problems and acceptance and usability with regard to our special target group were evaluated. Methods MEMENTO, a system of two e-ink tablets and a smartwatch, was tested in the domestic environment of dementia patients. Thirty participants from Italy, Spain and Austria took part in a 3-month field trial and compared the MEMENTO system to traditional strategies in everyday life. Quantitative and qualitative data were collected and frequency of use of the system was monitored. Results There were no significant changes in quantitative measurements, such as activities of daily living and caregiver burden over the duration of the 3-month field trial. More frequent usage was significantly correlated with positive attitude towards technology (r = 0.723, p Conclusion We show that a positive attitude towards technology is the essential variable for successful implementation of such systems, regardless of age. Participants showed great interest in digital solutions and agreed that technological systems will help in maintaining independency of persons with cognitive dysfunction in the future.

Considering that all teachers use technology intensively in educational environments, especially after the Covid-19 pandemic, special education teachers are also expected to integrate technology into their lessons effectively and efficiently in the future. Thus, this study aims to determine the attitudes of special education students towards assistive technologies. The data were collected in the 2020-2021 academic year. Participants were 240 special education students from various universities. The data collection tool was an attitude scale consisting of 4 dimensions and 18 items. Findings reported no significant difference in the attitudes towards assistive technologies regarding variables such as the duration of daily Internet use, grade level, and gender. However, a statistically significant difference was found in terms of variables such as the frequency of following technological developments and taking an assistive technology course. Based on scale mean scores, special education students have positive attitudes towards assistive technologies. Given that following the technological developments is effective in developing a positive attitude towards assistive technologies, special education students are recommended to closely follow current technological developments in future. It is considered that students who follow these technological developments will be more beneficial to students with special needs.

This paper presents the "Actional Model of Older people´s Coping with Health-Related Declines" to explain the use of a broad range of action alternatives of older persons for dealing with current or anticipated diseases, functional declines, activity limitations and participation restrictions. The general background is the action-theoretical model of intentional self-regulation of human development (e.g., Brandtstädter, 2006; RothermundBrandtstädter, 2019). Yet, our model provides an increased specification of major model components toward the situation of older people coping with current or anticipated health-related declines. The model development follows an adapted theory construction methodology (TCM) by Borsboom et al. (Perspectives on Psychological Science, 16(4), 756-766, 2021) and adapted principles for constructing practically useful theories by BerkmanWilson (Perspectives on Psychological Science, 16(4), 864-874, 2021). Regarding content, we further draw on models of the use of assistive technologies (ATs) and medical services, qualitative studies on reasons for using ATs, and quantitative studies on health-related goals. The resulting model includes these components: (1) Discrepancies between perceived or anticipated and desired health-related development, (2) health-related discrepancy reduction and prevention goals, (3) action possibilities for reducing or preventing health-related discrepancies, (4) further motivating and demotivating goals, (5) beliefs about effective means for reaching the goals (2) and (4), (6) generation of the particular coping actions by goals (2) and (4) in combination with beliefs about effective means, (7) external context factors, and (8) modes of joint decision-making and decision-making on behalf of older people. The explanatory and practical value of the model are discussed as well as its implications for future research and geropsychology teaching.

The present investigation is part of the EMPATHIC project aiming at develop an Empathic Virtual Coach (VC) able to promote seniors' healthy lifestyle and independent aging. To this end, it is fundamental to investigate users' preferences towards the implemented automatic system refined on the basis of users' preferences derived from previous field trials with Wizard of Oz (WoZ) experimental sessions. Data collection has been carried out involving three different countries (France, Norway and Spain) and a total of 71 volunteers was enrolled in the planned field trials. Five Virtual Agents (VAs) named Natalie, Alice, Lena, Christian and Adam were purposely designed and users' preferences were assessed using the shortened version of the Virtual Agent Acceptance Questionnaire (VAAQ). This specific tool, developed by members of the EMPATHIC project, includes 7 different sections, and the present work aims to disseminate results of four of the seven sections administered to participants, devoted at assessing respectively: users' willingness to interact (section II); pragmatic, hedonic (Identity and Feeling) and attractiveness qualities (section III); the type of task participants entrusted to the proposed agents among healthcare, housework, protection/security, and front office jobs (section V) and agents voice' quality (section VI). Results reveal seniors' appreciation of agents' pleasantness, originality, voice' quality and ability to engage users in a long lasting interaction with them.

Current medical science has not yet found a cure for dementia. The most important measures to combat dementia are to detect the tendency toward cognitive decline as early as possible and to intervene at an early stage. For this reason, screening for dementia based on language ability has attracted much attention in recent years. However, in most of the previous studies, the cohort of people with dementia has been smaller than the control cohort. In this paper, we use a pre-trained Japanese language model for text analysis and evaluate the effectiveness of text augmentation on a dataset consisting of Japanese-speaking healthy older adults and those with mild cognitive impairment (MCI). We also examined what tasks contributed to the results. This experimental setting can also be used to detect other diseases that may affect the language areas of the brain outside of the hospital.

[EN] Traditionally, text-to-speech has helped people overcome decoding difficulties with learning or hearing disabilities. Thanks to technological advances, consuming content in which learners use text and audio is more common. However, sign language allows an improvement in the transfer of knowledge and the integration of students with functional diversity. This tool allows the simultaneous translation into sign language of the teacher or speaker and dynamizes the learning of this by the classmates, improving the possibilities of socialization and exchange. In order to test the functionality of the application, a pilot test was carried out with the students of the Teaching Degree in the Special Educational Needs specialty in five face-to-face sessions. Among the contents that these students must acquire is the knowledge of sign language, valuing the application as very useful for learning and classroom use of this tool. It can also be used to promote communication between professionals in the workplace. In conclusion, we can highlight creating a tool for simultaneous translation into sign language applicable to the educational and socio-labor fields., [ES] Tradicionalmente, la conversión de texto a voz ha ayudado a las personas con problemas de aprendizaje o audición a superar las dificultades de decodificación. Gracias a los avances en la tecnología, consumir contenidos en los que texto y audio sean utilizados por los alumnos es más frecuente. Sin embargo la utilización de lengua de signos permite una mejora en la transferencia de conocimientos y la integración del alumnado con diversidad funcional. Esta herramienta permite la traducción simultánea a lengua de signos del profesor o ponente, así como dinamizar el aprendizaje de este por parte de los compañeros, mejorando las posibilidades de socialización e intercambio. Para probar la funcionalidad de la aplicación, se realizo un pilotaje con los alumnos del Grado de Magisterio en la especialidad de Necesidades Educativas Especiales en cinco sesiones presenciales. Entre los contenidos que estos alumnos deben adquirir esta el conocimiento de la lengua de signos, valorando la aplicación como muy útil para el aprendizaje y el uso en clase de esta herramienta. Además puede utilizarse para fomentar la comunicación entre los profesionales en el ámbito laboral. Como conclusión podemos destacar la creación de una herramienta de traducción simultanea a lengua de signos aplicable al ámbito educativo y socio-laboral.

This article is a retrospective overview of work performed in the domain of Active Assisted Living over a span of almost 18 years. The authors have been creating and refining artificial intelligence (AI) and robotics solutions to support older adults in maintaining their independence and improving their quality of life. The goal of this article is to identify strong features and general lessons learned from those experiences and conceive guidelines and new research directions for future deployment, also relying on an analysis of similar research efforts. The work considers key points that have contributed to increase the success of the innovative solutions grounding them on known technology acceptance models. The analysis is presented with a threefold perspective: A Technological vision illustrates the characteristics of the support systems to operate in a real environment with continuity, robustness, and safety; a Socio-Health perspective highlights the role of experts in the socio-assistance domain to provide contextualized and personalized help based on actual people’s needs; finally, a Human dimension takes into account the personal aspects that influence the interaction with technology in the long term experience. The article promotes the crucial role of AI and robotics in ensuring intelligent and situated assistive behaviours. Finally, considering that the produced solutions are socio-technical systems, the article suggests a transdisciplinary approach in which different relevant disciplines merge together to have a complete, coordinated, and more informed vision of the problem.

In recent years, there has been a renewed interest in using virtual reality (VR) to (re)create different scenarios and environments with interactive and immersive experiences. Although VR has been popular in the tourism sector to reconfigure tourists’ relationships with places and overcome mobility restrictions, its usage in senior cyclotourism has been understudied. VR is suggested to positively impact tourism promotion, cycling simulation, and active and healthy ageing due to physical and mental rehabilitation. The purpose of this study is to assess the senior citizens’ perceived experience and attitudes toward a designed 360° VR cyclotouristic experiment, using a head-mounted display (HMD) setting within a laboratory context. A total of 76 participants aged between 50 and 97 years old were involved in convergent parallel mixed-method research, and data were collected using a questionnaire based on the technology acceptance model, as well as the researchers’ field notes. Findings suggest that 360° VR with HMD can be an effective assistive technology to foster senior cyclotourism by promoting tourism sites, simulating the cycling pedaling effect, and improving senior citizens’ general wellbeing and independence with physical and mental rehabilitation.

Based on recent researches on the use of natural language processing techniques for very early detection of cognitive decline and the benefits of cognitive stimulation for people with cognitive impairments, the Dementia Monitoring application (DMapp) is developed inside the Memento project.The aims of this work are: (1) to present DMapp; (2) to report the results of two preliminary studies on DMapp; (3) to describe the clinical and experimental potentiality of DMapp.Italian people with the diagnosis of mild cognitive impairment due to Alzheimer's disease or dementia due to Alzheimer's Disease with a Mini-Mental-State-Examination between 24 and 28 (inclusive) were involved in the DMapp development prototype during the Lab Trial (4 subjects) and Filed Trial (5 subjects) of the Memento project. Qualitative and quantitative data were collected to evaluate participants' opinions, the DMapp ability to perform the automatic analysis of the speech and participants' visible emotional state effective. Ad hoc interviews, the Observed Emotion Rating Scale and performance metrics to solve different tasks were used. The relation between cognitive measures (global cognitive measures) and linguistic indexes values was considered using Euclidean distances between the participants.Linguistic indexes were calculated and seemed to classify the participants' performance as expected from cognitive measures. The DMapp was appreciated by people with cognitive impairment. Positive emotions were present.DMapp seems an interesting approach to monitor dementia symptoms progression and stimulate memory. Possible developments and open questions are discussed.

Abstract. Many older people suffer from functional declines and activity limitations, which reduce their autonomy and quality of life. Assistive technologies (ATs) could dampen such effects. However, many older people do not use ATs and it is important to understand, why they give away their benefits. In this article, we look at older peoples’ use of ATs from an action perspective on human development elaborated by Brandtstädter and colleagues. We review from this viewpoint models of AT use created mostly in information systems technology, business administration, and management sciences. The major focus is on the extent to which these models consider the relevant internal (mental) and external context of AT use, possible action alternatives, and autonomous, vicarious, and joint modes of decision-making about AT use. Systematic literature searches in PsycINFO, MEDLINE, and Google Scholar led us to 23 models. None of them contained as central variables any perceived discrepancies between the actual and desired developmental situation or any goals to reduce these discrepancies. No model included action alternatives to AT use beyond non-use such as trying harder on oneself, making environmental adaptations or using personal support. All models conceive of AT use as an act of the individual user, but neglected decision making about AT use by other persons on his or her behalf or a joint decision making of a potential user together with other persons (e.g., relatives). We discuss the background of these gaps, possibilities of a more comprehensive modeling of AT use, and practical implications (e.g., developmental counseling).

Digital assistive technology has potential for supporting older adults who depend upon community healthcare services. To boost the efficiency of those services, technological devices are often installed for care recipients as part of governed practice. However, the varying adoption of technology risks widening the digital divide. In response, the Assisted Living project engaged older adults in co-creating knowledge about users’ needs, to guide the development of technological solutions designed to support everyday living. This study sought to investigate how eight older adults in an assisted living facility in Norway, aged 81–92 years, evaluated user inclusion in a 3-year technology-oriented research project. Individual interviews, dialogue cafés, interventions with environmental sensors, and a final focus group discussion constituted sites for co-creation of knowledge. Participants’ answers to standardised questionnaires and statements during dialogue café meetings were collated into tables and the focus group discussion was thematically analyzed, with three themes identified: motivation for project engagement, experiencing and understanding participation in the project, and mixed feelings towards environmental sensors at home. The project revealed that older adults with impairments could nevertheless meaningfully contribute opinions about their needs. Applying a critical occupational perspective raised awareness regarding sociocultural assumptions about older adults in assisted living as frail and unable to participate, which may reinforce ageist and ableist stereotypes, as well as promote occupational injustice.

Made available in DSpace on 2020-12-10T19:50:41Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-02-17 OsloMet - Oslo Metropolitan University Norwegian Centre for International Cooperation in Education Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Visually impaired individuals often rely on assistive technologies such as white canes for independent navigation. Many electronic enhancements to the traditional white cane have been proposed. However, only a few of these proof-of-concept technologies have been tested with authentic users, as most studies rely on blindfolded non-visually impaired participants or no testing with participants at all. Experiments involving blind users are usually not contrasted with the traditional white cane. This study set out to compare an ultrasound-based electronic cane with a traditional white cane. Moreover, we also compared the performance of a group of visually impaired participants (N = 10) with a group of blindfolded participants without visual impairments (N = 31). The results show that walking speed with the electronic cane is significantly slower compared to the traditional white cane. Moreover, the results show that the performance of the participants without visual impairments is significantly slower than for the visually impaired participants. No significant differences in obstacle detection rates were observed across participant groups and device types for obstacles on the ground, while 79% of the hanging obstacles were detected by the electronic cane. The results of this study thus suggest that electronic canes present only one advantage over the traditional cane, namely in its ability to detect hanging obstacles, at least without prolonged practice. Next, blindfolded participants are insufficient substitutes for blind participants who are expert cane users. The implication of this study is that research into digital white cane enhancements should include blind participants. These participants should be followed over time in longitudinal experiments to document if practice will lead to improvements that surpass the performance achieved with traditional canes.

Physical rehabilitation aims at improving the functional ability and quality of life of patients affected by physical impairments or disabilities. Neurological diseases represent the largest cause of disability worldwide. For many, there is no cure and physiotherapy allows symptoms to be managed. Physiotherapy is based on the daily execution of exercises, traditionally under the supervision of a therapist. However, performing these exercises requires that both the patient and the physiotherapist are together so that the physiotherapist can assist the patient while exercising. For patients with a neurological condition, rehabilitation is a long term process, lasting months or even years. Not withstanding the personal costs, the cost of care/physiotherapy is high and represents €27,711 per year in Spain. This is compounded by a shortage of qualified therapists, often cited as one reason why stroke survivors do not received the recommended amount of therapy. The challenge is even greater in low to mid-income countries where there is a lack of trained personnel as well as under-served and remote regions. Technology can be employed to alleviate these problems by remotely monitoring a rehabilitation session taking place at home or anywhere in the community. This paper presents a computer vision-based system for home-use that automatically assesses how well the patient performs the exercises and transmits the information back to the clinic. The patient and physiotherapist do not need to be co-located. Gamification methods and techniques are used to engage patients when carrying out the rehabilitation routines. To this end, we propose a distributed gamified system that automatically evaluates the performance of exercises by analyzing and comparing motion curves using the DTW (Dynamic Time Warping) algorithm.

Introduction: Assistive technologies (AT) are products, equipment, devices, resources, methodologies and strategies that can be used in education to promote autonomous learning and academic success for students who have some type of disability. Objective: The objective was to analyze the AT available in medical courses in Brazil to support medical students with hearing and/or visual impairment. Methods: This is a descriptive study that used data from undergraduate medical courses participating in the Higher Education Census coordinated by Anísio Teixeira National Institute of Educational Studies and Research (Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira, INEP), in 2018. AT for students with hearing and/or visual impairment that were available in medical courses were evaluated considering the characteristics of the institution, such as the type of administration (public versus private), location (capital versus interior) and the year the course started (from the year 2000 versus before year 2000). Results: In 2018, there were 323 active medical courses in Brazil. Most of them (90%) confirmed the offer of at least one type of AT. The discipline of Brazilian Sign Language (LIBRAS, Linguagem Brasileira de Sinais) was the most frequently offered AT (80%) and tactile material was the least offered AT (32%). There was greater comprehensiveness of AT supply for medical students in courses with a private administration, compared to the public ones. The location and the year the course started did not influence the provision of AT in Brazil. The courses showed better AT comprehensiveness to support students with hearing impairment than those with visual impairment. Conclusion: Most medical courses supply AT for people with visual and/or hearing impairments who are medical students, but incompletely. Although the location of the course and the length of time that the course has been active did not influence AT provision, the study revealed inequalities. Medical students with visual and/or hearing impairments have access to assistive technologies especially in courses with private administration, adding more barriers to their financial possibilities, which are already sufficiently affected by the fact that they have to meet the essential needs common to people living with disabilities. Resumo: Introdução: As tecnologias assistivas (TA) são produtos, equipamentos, dispositivos, recursos, metodologias e estratégias que podem ser usados na educação para promover o aprendizado com autonomia e o sucesso acadêmico de estudantes que têm algum tipo de deficiência. Objetivo: O objetivo foi analisar as TA disponibilizadas nos cursos de medicina no Brasil para apoiar os estudantes com diminuição de audição e/ou visão. Métodos: Este é um estudo descritivo que usou dados de cursos de graduação em medicina que participaram do Censo do Ensino Superior coordenado pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), em 2018. As TA para estudantes com deficiência auditiva e/ou visual que eram disponibilizadas nos cursos de medicina foram avaliadas considerando as características da instituição, como a categoria administrativa (pública versus privada), a localização (capital versus interior) e o ano de abertura do curso (a partir do ano 2000 versus antes do ano 2000). Resultados: Em 2018, havia 323 cursos de medicina funcionando no Brasil. A maioria deles (90%) confirmou a oferta de pelo menos um tipo de TA. A disciplina de Língua Brasileira de Sinais foi a TA mais frequentemente ofertada (80%), e o material tátil foi a TA menos ofertada (32%). Houve maior completude de oferta de TA para estudantes de medicina nos cursos de administração privada quando se compararam aos públicos. A localização e o ano de abertura do curso não influenciaram a oferta de TA no Brasil. Os cursos apresentaram melhor completude de TA para apoiar estudantes com deficiência auditiva do que com deficiência visual. Conclusão: A maioria dos cursos de medicina oferta TA para os estudantes com deficiência visual e/ou auditiva, mas de modo incompleto. Apesar de a localização do curso e o tempo em que ele está em funcionamento não terem influenciado a oferta, o estudo revelou desigualdades. Estudantes de medicina com deficiência visual e/ou auditiva encontram TA sobretudo nos cursos de administração privada, adicionando mais barreiras às suas possibilidades financeiras, que já são suficientemente comprometidas pelo fato de terem que suprir as necessidades essenciais comuns às pessoas vivendo com deficiência.

In this paper we present a system for word-level sign language recognition based on the Transformer model. We aim at a solution with low computational cost, since we see great potential in the usage of such recognition system on hand-held devices. We base the recognition on the estimation of the pose of the human body in the form of 2D landmark locations. We introduce a robust pose normalization scheme which takes the signing space in consideration and processes the hand poses in a separate local coordinate system, independent on the body pose. We show experimentally the significant impact of this normalization on the accuracy of our proposed system. We introduce several augmentations of the body pose that further improve the accuracy, including a novel sequential joint rotation augmentation. With all the systems in place, we achieve state of the art top-1 results on the WLASL and LSA64 datasets. For WLASL, we are able to successfully recognize 63.18 % of sign recordings in the 100-gloss subset, which is a relative improvement of 5 % from the prior state of the art. For the 300-gloss subset, we achieve recognition rate of 43.78 % which is a relative improvement of 3.8 %. With the LSA64 dataset, we report test recognition accuracy of 100 %.

The COVID-19 crisis accelerated the adoption of technologies. Technological advancement is also expected in robotics applied to any sector, including in healthcare. The aim is to assess the professional perception of care robotics facing COVID-19. This study aimed to (1) select a tool for assessing different aspects of healthcare, (2) analyse the professional perception about the development, usefulness and helpfulness of technologies and robotics in the field of healthcare and (3) evaluate the correlation between the perceived helpfulness of care robotics and the selected tool. We implement five validated clinical tests which integrate 80 items about a person and their clinical situation. From the sample of 46 professionals, 95.65% affirmed that technology was moderately to completely useful for professional performance in the context of the pandemic, lowering to 67.39% when asked only about robotics; 93.48% stated that the inclusion of robotics in at least one health area affected by COVID-19 would have helped them. Finally, the variables extracted from clinical tests corresponded to the most relevant health areas as identified by the professionals. This research shows the potential of care robotics oriented towards healthcare from a care paradigm.

Object detection is an important computer vision technique that has increasingly attracted the attention of researchers in recent years. The literature to date in the field has introduced a range of object detection models. However, these models have largely been English-language-based, and there is only a limited number of published studies that have addressed how object detection can be implemented for the Arabic language. As far as we are aware, the generation of an Arabic text-to-speech engine to utter objects’ names and their positions in images to help Arabic-speaking visually impaired people has not been investigated previously. Therefore, in this study, we propose an object detection and segmentation model based on the Mask R-CNN algorithm that is capable of identifying and locating different objects in images, then uttering their names and positions in Arabic. The proposed model was trained on the Pascal VOC 2007 and 2012 datasets and evaluated on the Pascal VOC 2007 testing set. We believe that this is one of a few studies that uses these datasets to train and test the Mask R-CNN model. The performance of the proposed object detection model was evaluated and compared with previous object detection models in the literature, and the results demonstrated its superiority and ability to achieve an accuracy of 83.9%. Moreover, experiments were conducted to evaluate the performance of the incorporated translator and TTS engines, and the results showed that the proposed model could be effective in helping Arabic-speaking visually impaired people understand the content of digital images.

The use of assistive technologies in industrial environments to improve human ergonomics and comfort in repetitive and high effort tasks have increased considerably in the last decade. Predominantly, the goal is to provide additional physical support through lightweight and wearable devices, without posing major constraints to the human body movements. Towards achieving this objective, in this work we present a novel actuation mechanism for a soft assistive device, by taking into account the human elbow torque-angle profile. The proposed design integrates a single motor coupled with an elastic bungee and a cam-spool mechanism to enable energy exchange during the elbow flexion movement, while allowing for free-motions during the extension of the joint. A cable-driven transmission with passive elastic attachments is employed to implement compliant couplings with the wearer and to achieve easy donning/doffing. Experiments are conducted on two 3D printed functional prototypes. Results suggest that the assistive elbow torque is effectively transmitted with an average 90% success for balancing a 5N payload, and the free-motion range of 108 is measured for both flexion and extension.

Background Multiple sclerosis (MS) is the most common autoimmune inflammatory disease of the central nervous system in Europe, often causing severe physical, cognitive and emotional impairments. Currently, it is unclear whether the healthcare provisions of people with MS (PwMS) are in line with the recommendations for treatment based on guidelines or patients’ needs. The main objectives of the study are as follows: (a) to investigate how well PwMS are treated; and (b) to develop a needs-oriented, patient-centred care model. Methods This mixed-methods study focuses on adult PwMS living in Lower Saxony, a federal state in Germany. The qualitative study comprises focus groups with PwMS, physicians and people involved in the healthcare process as well as a future workshop. The quantitative study comprises a cross-sectional online survey and addresses the patient-relevant outcomes and needs, as previously determined by literature searches and focus groups. It will be administered to all PwMS who are insured by the statutory health insurance company involved in the project (n~7,000). The survey data will be linked to the longitudinal secondary data from the statutory health insurance company and data from the German MS registry where available. The linked and single data sources will be statistically analysed. Discussion By comprehensively comparing the current healthcare provisions with the needs and requirements of PwMS, the strengths and weaknesses of the overall healthcare process and provision of assistive devices can be identified. The barriers and facilitators of the health service providers and their impact on daily life will be explored (qualitative analyses). Reliable recommendations for improvements will be given based on a study population drawn from the largest statutory health insurance company in Lower Saxony (quantitative analyses). However, the inherent advantages and limitations of the qualitative and quantitative research approaches need to be considered. Trial registration The study is registered at German Clinical Trials Register DRKS00021741.

Background The worldwide increase in community-dwelling people with dementia underscores the need for innovative eHealth technologies that aim to provide support to both patients and their informal caregivers in the home setting. However, sustainable implementation of eHealth technologies within this target group can be difficult. Objective The goal of this study was to gain a thorough understanding of why it is often difficult to implement eHealth technologies in practice, even though numerous technologies are designed to support people with dementia and their informal caregivers at home. In particular, our study aimed to (1) provide an overview of technologies that have been used and studied in the context of informal dementia care and (2) explore factors influencing the implementation of these technologies. Methods Following an umbrella review design, five different databases were searched (PubMed, PsycINFO, Medline, Scopus, and Cochrane) for (systematic) reviews. Among 2205 reviews retrieved, 21 were included in our analysis based on our screening and selection procedure. A combination of deductive and inductive thematic analyses was performed, using the Nonadoption, Abandonment, Scale-Up, Spread, and Sustainability (NASSS) framework for organizing the findings. Results We identified technologies designed to be used “by informal caregivers,” “by people with dementia,” and “with people with dementia.” Within those groups, most of the represented technologies included, respectively: (i) devices for in-home monitoring of lifestyle, health, and safety; (ii) technologies for supporting memory, orientation, and day structure; and (iii) technologies to facilitate communication between the informal caregiver and person with dementia. Most of the identified factors influencing implementation related to the condition of dementia, characteristics of the technology, expected/perceived value of users, and characteristics of the informal caregiver. Considerably less information has been reported on factors related to the implementing organization and technology supplier, wider institutional and sociocultural context of policy and regulations, and continued adaptation of technology over time. Conclusions Our study offers a comprehensive overview of eHealth technologies in the context of informal dementia care and contributes to gaining a better understanding of a broad range of factors influencing their implementation. Our results uncovered a knowledge gap regarding success factors for implementation related to the organizational and broader context and continuous adaptation over the long term. Although future research is needed, the current findings can help researchers and stakeholders in improving the development and implementation of eHealth technologies to support informal dementia care.

Percutaneous osseointegrated (OI) implants are increasingly viable as an alternative to socket suspension of prosthetic limbs. Upper extremity prostheses have also become more complex to better replicate hand and arm function and attempt to recreate pre-amputation functional levels. With more functionality comes heavier devices that put more stress on the bone-implant interface, which could be an issue for implant stability. This study quantified transhumeral loading at defined amputation levels using four simulated prosthetic limb-types: (1) body powered hook, (2) myoelectric hook, (3) myoelectric hand, and (4) advanced prosthetic limb. Computational models were constructed to replicate the weight distribution of each prosthesis type, then applied to motion capture data collected during Advanced Activities of Daily Living (AADLs). For activities that did not include a handheld weight, the body powered prosthesis bending moments were 13-33% (range of means for each activity across amputation levels) of the intact arm moments (reference 100%), torsional moments were 12-15%, and axial pullout forces were 30-40% of the intact case (p≤0.001). The myoelectric hook and hand bending moments were 60-99%, torsional moments were 44-97%, and axial pullout forces were 62-101% of the intact case. The advanced prosthesis bending moments were 177-201%, torsional moments were 164-326%, and axial pullout forces were 133-185% of the intact case (p≤0.001). The addition of a handheld weight for briefcase carry and jug lift activities reduced the overall impact of the prosthetic model itself, where the body powered forces and moments were much closer to those of the intact model, and more complex prostheses further increased forces and moments beyond the intact arm levels. These results reveal a ranked order in loading magnitude according to complexity of the prosthetic device, and highlight the importance of considering the patient's desired terminal device when planning post-operative percutaneous OI rehabilitation and training.

Assistive technologies including assistive robots (AT/AR) appear to be a promising response to the increasing prevalence of older adults in need of care. An increasing number of long-term care facilities (LTCFs) try to implement AT/AR in order to create a stimulating environment for aging well and to reduce workload for professional care staff. The implementation of new technologies in an organization may lead to noticeable cultural changes in terms of social interactions and care practices associated with positive or negative emotions for the employees. This applies especially for LTCFs with high rates of vulnerable residents affected by increasing care needs and specific ethics in nursing and cultural rules within the setting. Thus, systematic consideration in leadership management of emotions and ethical aspects is essential for stakeholders involved in the implementation process. In this article, we explicitly focus on the emotions of the employees and leaders within LTCFs. We relate to direct consequences for the organizational well-being and culture, which is of course (indirectly) affecting patients and residents. While aspects of technology acceptance such as safety and usefulness are frequently discussed in academic literature, the topic of emotion-management and ethical questions during the organizational implementation process in LTCFs received little attention. Emotional culture entails affective values, ethical norms and perceptions of employees and further investigation is needed to address the importance of transformational leadership during implementation process. For this purpose, we developed a three-staged assessment tool for implementation of AT/AR in long-term care institutions. Acceptance (A), ethical acceptability (A) and emotional consequences (E) are considered as comprehensive assessment, in which emotional consequences comprise management aspects of transformational leadership (T), emotion-management (E) and organizational culture (O). Based on AAE and TEO, this paper presents an integrated framework illustrated with a illustrative example and aims to combine established approaches with ethical insights in order to unfold potentials of AT/AR in LTCSs.

The present paper presents some of the results obtained by the research team of the project "Noninvasive monitoring system and health assessment of the elderly in an intelligent environment (ROSmartAgeing)", within the Core Program. Worldwide, multiple systems for monitoring the health of the elderly have been developed. Based on the analysis of the literature in the field, the author briefly presents concepts related to IoT, protocols and benefits of IoT technology, the impact on the elderly, assistive technologies for monitoring current activities and lifestyle. These are the support for the development of a system of care for the elderly by monitoring the current activities and lifestyle.

© 2019 The Author(s). Currently, the assistive technologies (ATs) market is underdeveloped, which limits individual choices. Many people appear reconciled to using available products that, at best, match functionalities to compensate for physical deficiencies. Yet people express a desire for personalized, elegant, discreet and bold artefacts that match their lifestyle and provide opportunities for self-expression. This study adopts a materiality-inspired methodology to explore ATs and to elicit insights into the perceptions and emotions of the study participants towards them. A comparative exploratory study between the UK and Taiwan has been conducted to explore diverse and cross-cultural perceptions. The findings suggest that the design of ATs needs to go beyond traditional considerations, such as price and compliance, and instead focus on how these products enhance users’ positive sense of self. This in return may increase the rate of successful adoption of ATs in everyday life.

Made available in DSpace on 2022-04-29T08:28:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01 BACKGROUND: Mobility devices such as walkers and wheelchairs are often associated with certain stigma. Such devices must be designed with the goal of reducing stigma to decrease the abandonment-rate. Yet there is little empirical evidence on how mobility devices are perceived. OBJECTIVE: This study set out to explore how (N= 40) non-disabled individuals perceived four common mobility devices including a traditional walker, rollator, manual wheelchair and a powered wheelchair. METHODS: A questionnaire based on semantic differential scales was designed. RESULTS: The results show that the more elaborate devices are perceived as more aesthetical and lighter, yet more unsafe and impractical. Moreover, respondents familiar with mobility devices through family and friends gave more biased negative responses in terms of device characteristics compared to non-experienced respondents. Next, non-experienced respondents perceived the manual wheelchair to be more stigmatizing compared to experienced respondents. CONCLUSIONS: The findings evidence that different designs of products in the same category can evoke different perceptions of non-users regarding practical, aesthetical and symbolic aspects. Insight into how different design characteristics are associated with perceptions of non-users may contribute to the comprehension of assistive technology stigma and may support design decisions that minimize negative judgments and emphasize positive perceptions.

Assistive technologies offer capabilities that were previously inaccessible to individuals with severe and profound hearing loss who have no or limited access to hearing aids and implants. This literature review aims to explore existing assistive technologies and identify what still needs to be done. It is found that there is a lack of focus on the overall objectives of assistive technologies. In addition, several other issues are identified i.e. only a very small number of assistive technologies developed within a research context have led to commercial devices, there is a predisposition to use the latest expensive technologies and a tendency to avoid designing products universally. Finally, the further development of plug-ins that translate the text content of a website to various sign languages is needed to make information on the internet more accessible.

Stroke is a standout amongst the most imperative reasons of incapacity on the planet. Due to partial or full paralysis, the majority of patients are compelled to rely upon parental figures and caregivers in residual life. With post-stroke rehabilitation, different types of assistive technologies have been proposed to offer developments to the influenced body parts of the incapacitated. In a large portion of these devices, the clients neither have control over the tasks nor can get feedback concerning the status of the exoskeleton. Additionally, there is no arrangement to detect user movements or accidental fall. The proposed framework tackles these issues utilizing a brain-controlled lower limb exoskeleton (BCLLE) in which the exoskeleton movements are controlled based on user intentions. An adaptive mechanism based on sensory feedback is integrated to reduce the system false rate. The BCLLE uses a flexible design which can be customized according to the degree of disability. The exoskeleton is modeled according to the human body anatomy, which makes it a perfect fit for the affected body part. The BCLLE system also automatically identifies the status of the paralyzed person and transmits information securely using Novel-T Symmetric Encryption Algorithm (NTSA) to caregivers in case of emergencies. The exoskeleton is fitted with motors which are controlled by the brain waves of the user with an electroencephalogram (EEG) headset. The EEG headset captures the human intentions based on the signals acquired from the brain. The brain-computer interface converts these signals into digital data and is interfaced with the motors via a microcontroller. The microcontroller controls the high torque motors connected to the exoskeleton's joints based on user intentions. Classification accuracy of more than 80% is obtained with our proposed method which is much higher compared with all existing solutions.

A key challenge that Immersive applications have to overcome is cybersickness. Cybersickness is particularly prevalent in dynamic applications such as vehicles simulators. The work presented here aims to understand the cause of cybersickness symptoms in an assistive technology (AT) application, the virtual wheelchair training simulator. This evaluation is performed in terms of errors made during experience and post-experience Simulator Sickness Questionnaire (SSQ). The performance metrics analyzed are time to complete the proposal task and number of collisions (errors/mistakes). The post-experience questionnaires (subjective measurements) collected the user’s experience in terms of simulator sickness by applying the Simulator Sickness Questionnaire (SSQ) and immersion questions. The experiments were conducted with 10 participants. In terms of results, analysis of human factors reveals that the average cybersickness score is slightly higher for women compared to men. However, these differences were not statistically significant. There was an inverse correlation between cybersickness symptoms and task performance as well as between cybersickness symptoms and immersion.

La generación de estrategias de comunicación que permitan acercar al público con discapacidad visual a los museos se ha convertido en un desafío importante para la museología. Como respuesta a esta necesidad se diseñó, prototipó y evaluó un sistema de navegación para ambientes internos que permite a las personas con discapacidad visual acceder a exposiciones en el Museo de Ciencias Naturales de La Salle del Instituto Tecnológico Metropolitano (Medellín, Colombia). El procedimiento utilizado se presenta como una metodología con dos etapas. La primera consistió en el diseño y desarrollo del prototipo del sistema de navegación y la segunda consistió en la evaluación del sistema. El diseño del sistema fue el resultado de la adaptación de metodologías contemporáneas de innovación tales como el Design Thinking y el Creative Problem Solving (CPS), aplicadas al diseño de productos tecnológicos. Se desarrolló un prototipo funcional que incluía una aplicación iOS para teléfonos inteligentes, guías podotáctiles, auriculares de conducción ósea, detectores de obstáculos e identificadores de códigos QR. Durante la etapa de evaluación se llevaron a cabo experimentos en una de las salas del museo con 27 personas, quienes presentaban discapacidad visual. Los resultados indicaron que el sistema desarrollado es eficaz como herramienta de navegación y que proporciona información acerca de los especímenes en una exposición, lo que permite concluir que esta experiencia es replicable en otros entornos museográficos y en otros museos. The generation of communication strategies that allow bringing the visually impaired public closer to museums has become an important challenge for museology. As a response to this need, a navigation system for inner environments was designed, prototyped and evaluated, which allows visually impaired people to access exhibitions at the La Salle Museum of Natural Sciences of the Instituto Tecnológico Metropolitano (Medellín, Colombia). The procedure used in this work is presented as a methodology with two stages. The first stage consisted of the design and development of the prototype of the navigation system, and the second stage was the evaluation of the system. The design of the system was the result of the adaptation of contemporary methodologies of innovation such as Design Thinking and Creative Problem Solving (CPS) applied to the design of technological products. A functional prototype which included an iOS app for smartphone, podotactile guides, bone conduction headphones, obstacle detectors and QR code identifiers, was developed. During the evaluation stage, experiments were conducted in one of the museum rooms with 27 people with visual disabilities. The results indicated that the developed system is effective as a navigational tool that provides information about the specimens of an exhibition, which allows concluding that this experience is replicable in other museographic environments and in other museums.

A diverse array of assistive technologies have been developed to help Visually Impaired People (VIP) face many basic daily autonomy challenges. Inertial measurement unit sensors, on the other hand, have been used for navigation, guidance, and localization but especially for full body motion tracking due to their low cost and miniaturization, which have allowed the estimation of kinematic parameters and biomechanical analysis for different field of applications. The aim of this work was to present a comprehensive approach of assistive technologies for VIP that include inertial sensors as input, producing results on the comprehension of technical characteristics of the inertial sensors, the methodologies applied, and their specific role in each developed system. The results show that there are just a few inertial sensor-based systems. However, these sensors provide essential information when combined with optical sensors and radio signals for navigation and special application fields. The discussion includes new avenues of research, missing elements, and usability analysis, since a limitation evidenced in the selected articles is the lack of user-centered designs. Finally, regarding application fields, it has been highlighted that a gap exists in the literature regarding aids for rehabilitation and biomechanical analysis of VIP. Most of the findings are focused on navigation and obstacle detection, and this should be considered for future applications.

This paper describes an ongoing research project which explores the design and use of inexpensive robotics, artificial intelligence techniques, and human–computer interaction methods, to enrich assisted living environments. Such environments provide help to the inhabitants of a home or office, assisting them to perform daily activities, helping them to socialize and interact with others, and to provide enhanced levels of security and safeness. We present the development of an inexpensive robotic solution to help people with disabilities and/or older adults to perform their daily activities. It can be used as a remote controlled surveillance system, and also as a personal assistant. It is able to recognize each inhabitant, his/her emotions, and detect abnormal situations such as falls and health problems. The whole system is designed to operate solely within a local network and special attention is given to the privacy and data protection of the users. authorsversion published

Place: Germany; International audience; PURPOSE: Most opponents of assistive technologies in orthopedic surgery consider them as a marketing ruse or fashion. Our hypothesis was that many innovations in modern knee arthroplasty are not following the Scott Parabola. This parabola represents the visual curve of a procedure or therapy showing great promise at the beginning, becoming the standard treatment after reports of encouraging results, only to fall into disuse due to adverse outcome reports. This study aimed to assess the interest in these assistive technologies by (1) their number of publications/year and (2) their actual surgical use reported in the National Joint Registries.METHODS: The search was performed through PubMed, EMBASE, and MEDLINE databases from 1997 to 2021 inclusive to identify all available literature that described the use and results of assistive technologies or new surgical techniques in knee arthroplasty. In the Australian and Norwegian registries, the number of cases performed with these techniques in knee arthroplasty has been quantified year by year.RESULTS: Following the initial online search, a total of 4085 articles was found. After the assessment mentioned above, 2106 articles were included in the study. The orthopedic techniques assessed in this study are not following the "Scott's parabola" in the literature. Computer-assisted knee arthroplasty and patient-specific instrumentation have increased quickly to have reached a plateau, with a stable number of publications over the last 6 years. The number of publications concerning robotic surgery, accelerometers and sensors continue to rise. In the Australian registry, the proportion of primary TKA performed by computer-assisted systems increased from 2.4% in 2003 to 32% in 2019. In the Norwegian registry, the proportion of computer-assisted TKA remained between 8 and 12% of primary TKA since 2007.CONCLUSION: Most of the innovations in modern knee arthroplasty are not following the Scott Parabola. After a fast rise, these techniques do not disappear but continue to evolve. Their evolution is synergistic, and techniques appeared to be linked to each other's. Despite persisting concerns about the cost-efficiency of assisting technologies in knee arthroplasties, the interest and use do not decrease and seems to be directly linked to an exponential increase in interest for a better understanding of alignment targets and improved functional recovery.

ObjectivesThe study objectives were: 1) to develop a masticatory index for evaluating masticatory ability in patients wearing a dental prosthesis, including complete dentures (CD), removable partial denture (RPD), and fixed partial denture (FPD), 2) to test the reliability and validity of the index, and 3) to determine whether the index better reflected patients’ masticatory ability compared with conventional subjective and objective measures.MethodsThe present cross-sectional study consisted of 2 phases: 1) developing the Chulalongkorn University masticatory index (CUMI) consisting of 20 food items in 5 masticatory difficulty grades using a 3-point Likert scale, and 2) application of the CUMI in 110 patients wearing a dental prosthesis, including CD, RPD, and FPD (control group). The CUMI test-retest reliability was reevaluated 2 weeks later. The convergent validity was compared with objective masticatory performance evaluated with a standard peanut chewing test, and subjective eating impacts evaluated by the Oral Impacts on Daily Performances Index. Oral and denture status were determined clinically. The associations between CUMI score, peanut particle size, and eating impact score was identified using Spearman’s correlation coefficient. To evaluate discriminant validity, the associations between masticatory ability measurements and oral and denture status were analyzed using regression analyses.ResultsThe CUMI’s Cronbach’s alpha and intraclass correlation coefficient values were 0.89 and 0.95, respectively. The convergent validity was shown by significant associations between the increased CUMI score, smaller peanut particle size and decreased eating impact score. Multivariable analyses found that the CUMI score, peanut particle size, and percentage of having an eating impact were significantly associated with the number of remaining teeth and posterior occluding pairs, and type and quality of dental prosthesis. However, the CUMI demonstrated better discriminant validity because significant dose-response relationships were found only between the decreased CUMI score and increased tooth loss severity, and unacceptable denture quality. Adjusted R2values of the CUMI models were the highest, followed by those of peanut particle size and eating impact.ConclusionCUMI is a reliable and valid tool to evaluate masticatory ability of patients wearing a dental prosthesis, including CD, RPD, and FPD. Due to a better discriminant validity, the CUMI better reflects masticatory ability of patients compared with conventional subjective and objective masticatory ability measures.

Nowadays, we can find ourselves surrounded by technology, whether in public spaces, our homes or even within our body space. It is difficult to imagine how we could survive without some of the devices, and their functions, that we take for granted today but were not available a few years ago. However, some persons are deprived from this control which limits not only their movement and life quality but also the overall control over the surrounding environment.

Since transition to higher education emerged as a research topic in the early 1970s, scholarly inquiry has focused on students without impairments and, what is more, little attention has been paid to the role of digital technologies. This article seeks to address this knowledge gap by looking at the university experiences of a group of first-year students with vision impairments from New Zealand, and the way they use digital tools, such as social media and mobile devices, to manage their transition-related challenges. The article summarises the findings from a longitudinal qualitative project which was methodologically informed by action research (AR). The article explores and discusses scholarly inquiry of transition to university and introduces a conceptual framework which includes five overlapping stages, the transition issues faced by the students and the roles played by digital technologies. The article updates and expands the theoretical understanding of transition to higher education and provides empirical evidence for practitioners to support the needs, inclusion, and participation of young people with disabilities in the tertiary setting.

Cities face an evident demographic change, making assistive technologies (AAL) an interesting choice to support older adults to autonomously age in place. Yet, supportive technologies are not as widely spread as one would expect. Hence, we investigate the surroundings of older adults living in Vienna and analyse their “socio relational setup”, considering their social integration and psychophysical state compared to others (health, fitness, activeness, contentedness). Method: Our data included 245 older adults (age: M = 74, SD = 6654) living in their own homes (2018–2020 with different grades of needing support). We calculated univariate and multivariate models regressing the socio-relational setup on the change of routines, technology attitude, mobility aid use, internet use, subjective age, openness to move to an institutional care facility in the future, and other confounding variables. Results: We found a strong correlation between all categories (health, fitness, activeness, contentedness) of older adults comparing themselves to their peers. Among others, they are significantly related to institutional care openness, which implies that participants who felt fitter and more active than their peers were less clear in visualising their future: unpleasant circumstances of ageing are suppressed if the current life circumstances are perceived as good. This is an example of cognitive dissonance.

Since the beginning of the 21st century, the lifespan of people born with Down syndrome (DS) has increased. They now outlive their parents and rely on their relatives who usually sacrifice their own families to care for their disabled siblings. To reduce the pressure on families and the wider community, it is crucial to prepare DS people for independent life from early childhood. Emerging technologies can significantly support the process of acquiring the skills that are necessary for solving real-life problems at home and work. To assess their impact and estimate how much they are implemented in inclusive education, a review of 564 papers published after 2015 was done using the PRISMA review model. After gradual exclusion, 24 papers were used for the final review. Thematic analysis resulted in four themes with one common concept: variety. The results of examining the four research questions defined in the paper’s background confirm that the synergy of emerging assistive technologies and inclusive education has the potential of becoming a very effective strategy for creating an independent life for DS individuals. Many questions remain open, mainly related to a DS persons’ specific needs and capabilities. The acceptance of the proposed synergy will depend on them.

BackgroundSoft tissue tension is treated as a crucial factor influencing the post-THA dislocation. The femoral offset is regarded as one of the major parameters responsible for the stabilization of the prosthesis. It is unclear which soft tissue is mostly affected by the offset changes.MethodsA finite element model of the hip was created. The model comprised muscles, bones, a stem, the acetabular component and a liner. The muscles were modelled as a Hill-type musculo-tendon nonlinear springs. Nonlinear analyses of the hip flexion and internal rotation were performed for the two values of the femoral stem offset.ResultsWe observed that the quadratus femoris and gluteus medius produce the largest resisting moment opposing the external load excreted by the surgeon during the intraoperative hip dislocation test.ConclusionsAn increased femoral offset increases the stretching of the quadratus femoris muscle significantly and provides the growth of its initial passive force. This muscle serves as a stiff band, providing stabilisation of the hip prosthesis, measured during the simulated intraoperative test.

Introduction Health benefits package (HBP) is regarded as one of the main dimensions of health financing strategy. Even with increasing demands for prosthetics and orthotics (P&O) services to approximately 0.5% of the world’s population, only 15% of vulnerable groups have the chance to make use of such benefits. Inadequate coverage of P&O services in the HBP is accordingly one of the leading reasons for this situation in many countries, including Iran. Aims The main objective of this study was to find and prioritize solutions in order to facilitate and promote P&O services in the Iranian HBP. Study design A mixed-methods (qualitative-quantitative) research design was employed in this study. Methods This study was conducted in two phases. First, semi-structured interviews were undertaken to retrieve potential solutions. Then an analytic hierarchy process (AHP) reflecting on seven criteria of acceptability, effectiveness, time, cost, feasibility, burden of disease, and fairness was performed to prioritize them. Results In total, 26 individuals participated in semi-structured interviews and several policy solutions were proposed. Following the AHP, preventive interventions, infant-specific interventions, inpatient interventions, interventions until 6 years of age, and emergency interventions gained the highest priority to incorporate in the Iranian HBP. Conclusion A number of policy solutions were explored and prioritized for P&O services in the Iranian HBP. Our findings provide a framework for decision- and policy-makers in Iran and other countries aiming to curb the financial burdens of P&O users, especially in vulnerable groups.

Objectives The purposes of this study were to analyze the effects of single posterior implant restorations delivery on the redistribution of bite force and to evaluate the changes in occlusal force distribution of prostheses and potential influencing factors on occlusion variation at different stages. Materials and methods Thirty-two single posterior restorations in 30 participants (18 women and 12 men aged 27 to 75 years) were placed into either a unilateral single-tooth defect (n = 17) or on either side of a bilateral teeth defects (n = 15). The bite force (%) of the prostheses, teeth and segments at the maximum intercuspation position (MIP) was evaluated using a T-scan at 5 stages (pre-placement, immediately following placement, and 2 weeks, 3 months, and 6 months post-placement). Results The occlusal force of implant-supported prostheses was significantly (P = .000) lower than those of the control natural teeth at the baseline, then no significant difference was found with that of the mesial teeth at 3 months, and finally it was significantly (P = .000) lower than that of the distal teeth at 6 months; meanwhile, it significantly (P = .008) increased by a mean of 2.04 times from 2 weeks (3.39 ± 2.61%) to 3 months (6.90 ± 4.77%), whereas no significant difference (P = .900) was found from 3 months (6.90 ± 4.77%) to 6 months (7.31 ± 4.60%). In addition, the bite force of the posterior segment on the restored side of both unilateral and bilateral gaps was significantly (P = .013,.001) improved by 3.31% and 6.83%, respectively, although the discrepancy in bite force significantly (P = .039) increased from an initial 3.52% to 5.02% for subjects with bilateral defects, accompanying increases in the proportion (15.38%) of the level III bilateral bite force deviation (P >.05). Conclusions Bite force and masticatory ability can be improved with the immediate delivery of a single posterior implant restoration. The bite force distributed on the implant prosthesis inevitably increases after placement of implant prostheses, a routine follow-up and occlusal evaluation are strongly needed.
