Disability and Rehabilitation-Assistive Technology最新文献

A paediatric Assistive Technology (AT) Provision Program was implemented by a non-governmental rehabilitation facility in rural South India to support rehabilitation providers in providing needed AT access for children with disabilities. Capacity-building measures for providers and other supports based on the AT needs, barriers, and facilitators to AT access were implemented that aligned with the AT global report for low-middle income countries (LMIC). This study explores how the initiatives from the AT Provision Program have influenced the perspectives of rehabilitation providers on AT access.

Using a qualitative design eight paediatric rehabilitation providers were purposively sampled for virtual semi-structured interviews. Findings were analysed using thematic analysis.

Six overarching themes were identified: (1) Stigma associated with AT use, (2) Organisational response to changing needs, (3) Financial factors related to family socioeconomic status and the organisation providing AT services, (4) Inequity of AT service access in rural areas, (5) Provider AT awareness and confidence and, (6) Quality assurance. Rehabilitation providers' experiences informed future AT capacity-building strategies within a low-resource context. Our findings provide valuable insights for the development of comprehensive AT Provision Program initiatives to provide AT access for children with disabilities in LMIC settings.

Context: Assistive technologies have been identified by researchers and public policies of the Western world to be promising tools to face the challenge of maintaining quality of life of older people, and especially for nursing home habitants. Independence, autonomy, and participation are major determinants of quality of life of nursing homes habitants. Maintaining quality of life is nowadays a priority for public health policies and institutions of the where the population is growing older every year.

Method: This PRISMA-ScR review aims to determine which assistive technologies are used to promote autonomy, independence, and social participation of nursing home habitants. An electronic search was conducted for English, French articles to identify research studies using CINAHL, PubMed, Cochrane Library, PsycINFO, and Googlescholar.

Results: 12 papers published between 2009 and 2023 described 6 assistive technologies: technologies integrated into the environment, monitoring technologies, surveillance technologies, information and communication technology, social assistance robots, virtual reality. Six types of AT are currently used worldwide to maintain autonomy, independence and participation of people living in nursing homes. Their use is mainly perceived as positive by habitants, care and non-care staff, next of kin, and experts despite some concerns regarding ethical, financial, consideration.

Discussion: Nevertheless, their impact on habitant's autonomy, independence and participation still needs to be measured using suitable tools to understand their real impact on the quality of life of the elderly.

Purpose: Prior research has begun establishing the efficacy of animation in brain-computer interfaces access to augmentative and alternative communication (BCI-AAC). However, the use of animation in P300-BCI-AAC for children is in the early stages and largely limited to single item highlighting of extended durations. In pursuit of practical application, the present study aims to evaluate children's event-related potential (ERP) characteristics and user experience during a task involving an animated P300-BCI-AAC system.

Materials and methods: The system utilizes multi-item zoom animations to access a 28-pictorial symbols. Participants completed a fast (100 ms) and slow (200 ms) zoom animation highlighting conditions wherein four pictorial symbols were highlighted concurrently.

Results: The proposed display appears feasible, eliciting all targeted ERPs. However, ERP amplitudes may be reduced in comparison to single-item animation highlighting, possibly due to distraction. Ratings of mental effort were significantly higher for the 100 ms condition, though differences in the frontal P200/P300 ERP did not achieve significance. Most participants identified a preference for the 100 ms condition, though age may impact preference.

Conclusions: Overall, findings support the preliminary feasibility of a proposed 28-item interface that utilises group zoom animation highlighting of pictorial symbols. Further research is needed evaluating ERP characteristics and outcomes from online (real-time) use of animation-based P300-BCI-AAC for children with severe speech and physical impairments across multiple training sessions.

Purpose: Digital health technologies have the potential to advance rehabilitation. The Virtual Engagement Rehabilitation Assistant (VERA) is a digital technology, co-designed to increase service-user engagement and promote self-management. This qualitative study explored staff and service-user perceptions of implementing VERA on a UK complex inpatient rehabilitation ward.

Methods: Purposively sampled service-users were allocated to VERA for up to six weeks. The Non-adoption, Abandonment, Scale-up, Spread and Sustainability (NASSS) framework underpinned service-user post-intervention interviews and staff focus groups, and structured analysis of the data. Seven service-users were interviewed. Nine staff contributed to focus groups.

Results: A framework analysis identified themes (and subthemes) structured by the NASSS framework domains: 1. Nature of Clinical Condition, 2. Technology (Ease of Use, Holding Information/Resources in a single Digital Location, Appointments), 3. Value Proposition (Structuring Time, Feedback, Unexpected Benefits) 4. Adopters (Confidence in using Technology, Usefulness), 5. Wider Organisation. Ease of use and storage of key information in a single location were beneficial. Reliability, and provision of accurate and timely feedback to staff and service-users, were identified as essential.

Conclusions: A blended approach is required to meet staff and service-user needs. The potential for VERA in a community setting was identified and requires further investigation. Learning from VERA will support development of other digital technologies and their implementation.

Purpose of the article: The aim of this study was to determine user satisfaction with manual wheelchairs in the United Kingdom and to determine areas that could be improved to help drive future design and development.

Materials and methods: Manual wheelchair users, aged 18-65 years old living in the United Kingdom, were invited, to complete an online cross-sectional questionnaire. The link to the questionnaire was distributed using a range of methods to charities, organisations and wheelchair user groups via invitation by email and social media. Responses were gathered from 122 respondents and analysed using descriptive statistics, cross-tabulation and content analysis.

Results: Respondents felt comfort (39.3%), weight (35.4%), manoeuvrability (34.3%) and durability (30.7%) were the most important features of a wheelchair. Seventy percent of respondents that were "not at all satisfied" with their current wheelchair were fitted by the National Health Service (NHS, X² = 42.39, p < 0.001). Ninety percent of respondents who were "not at all satisfied" with their current wheelchair experienced issues with comfort (X² = 17.82, p = 0.001). Sixty percent who were "not satisfied at all" with their wheelchair had not chosen their wheelchair (X² = 25.15, p < 0.001).

Conclusion: Wheelchair satisfaction was largely determined by comfort, location of the users' wheelchair fitting (for example the NHS) and users choosing their own wheelchair. Future wheelchair designs should utilise a user centred and inclusive design approach to cater for a wider range of individual needs and requirements.

Purpose: This study aimed to evaluate the clinical applicability of a customised power wheelchair joystick using rapid prototyping with 3D modeling and printing technology within a rehabilitation centre for patients with cervical spinal cord injury.

Materials and methods: Two male participants with tetraplegia following cervical-level spinal cord injury who had difficulty operating a powered wheelchair were recruited. The procedure of the joystick-making and training service consists of four steps: (1) driving evaluation; (2) digital fabrication; (3) functional test; and (4) driving training. K-QUEST 2.0 (Korean-Quebec User Evaluation of Satisfaction version 2.0) was used to measure the usability of the off-the-shelf and customised joystick.

Results: During the application process, several redesign stages were required to obtain the final customised joystick. After participants attended a 30-min driving training five times per week for 8 weeks, the usability of the customised joystick was higher than that of the off-the-shelf one.

Conclusion: Providing the customised joystick-making and training service can be used in hospitalised rehabilitation centre before the hospital discharge of patients and returns to their everyday lives.

Purpose: This pilot study aimed to (a) investigate opportunities for immersive Virtual Reality (VR) technology in communication, physical, and visual rehabilitation by examining the interaction of people without disabilities in a range of structured virtual environments; and (b) validate research protocols that might be used to evaluate the physical, visual, and verbal interaction of users in virtual worlds, and their safety while using the technology.

Methods: Thirteen adults identifying as people without disability were exposed to VR via a head-mounted display. A video-review method was used to qualitatively code and analyse each participant's communication, movement, orientation, and support needs.

Results: All participants oriented to their virtual environments sufficiently to use applications. Their spoken language was effective for interaction, although unconventional social behaviours were also observed. Two participants reported minor adverse reactions consistent with mild cybersickness.

Conclusion: The results provide insight into the types of environments and characters that support the greatest communicative, physical, and visual interaction in immersive VR. The tested protocols are useful to assess safety when using VR, and to observe communicative, physical, and visual interaction with virtual environments and characters. Implications for future research and use of VR with people with communication, physical and visual disability are discussed.

Purpose: This study addresses the learning requirements of learners with learning difficulties by monitoring their learning experience in an Intelligent Tutoring System. Intelligent Tutoring Systems were developed to enrich the teaching-learning process.

Materials and methods: In the present work, the interface is designed and developed utilizing the potential of Artificial Intelligence to meet their individual needs. Designing an online learning platform for a learners with learning difficulties requires consideration of their learning problems and preferences. The interface was developed focusing on all the requirements of the LD learners. The objective of the present study is to monitor the learning experience in the form of induced emotions and cognitive load of the learners to determine the impact of learning.

Results: 83 learners were observed during various stage of learning. The results obtained through the Support Vector machine (SVM) classification technique showed the positive attitude towards intelligent tutoring. The analysis revealed that a total of 0.23% of learners were positively induced. Their learning experience was positive and effective. The cognition load on learners was minimum with single-mode instruction and least disturbed.

Conclusions: The system was improved based on preference feedback on design features. This helps in improving content design and creating device independent and responsive visual design. The fatigue effect analysis on cognitive load implied that multiple modes of instruction increased drowsiness. Single mode of instruction have a positive impact on the learning process and it reduces the cognitive load of the learners.Implications for RehabilitationThe user interface designed and developed for learners with Dyslexia, Dysgraphia and Dyscalculia has learning disabled-friendly features. These can be used to create a device-independent and responsive design.Learning experience is monitored along with the impact on cognitive load of the learners.The research helps in understanding the stimulation and response of learners with learning disability for different learning conditions.Most existing learning systems are limited to non-learning-disabled learners. The ITS developed during research presents a Universal learning design helpful for all learners with and without learning disability.

Purpose: The aim of this study was to investigate the experiences of standing powered wheelchair (SPWC) users with spinal cord injury (SCI).

Materials and methods: This cross-sectional study included 20 participants with SCI. SPWC daily usage time (total, in sitting position and standing position) and the frequency of using the SPWC's standing feature were recorded. Participants' level of satisfaction and comfort associated with the SPWC were assessed on a five-point Likert scale. If there was a dissatisfaction reason with the SPWC, the issues related to it were recorded. Participants were asked about their positive and adverse experiences with the use of SPWC.

Results: Mean age of the participants was 41.65 (± 9.35) years. Eighty percent were tetraplegic. Ninety percent of the participants stood for at least 30 minutes at least one day a week, and 55% stood for at least 30 minutes at least four days a week. The most commonly reported perceived benefits were improvement in activities of daily living, bowel movements, and blood pressure regulation, better perception of body image, and feeling better. The most frequently identified reasons for dissatisfaction with the SPWC were its big dimensions, heavy weight, and difficulty of use in indoor environment and on uneven surfaces.

Conclusions: The findings show positive perceived experiences for SPWC users with SCI in terms of physical, social, and psychological aspects. Prospective controlled studies are needed to explore the benefits of SPWC use regarding secondary complications of SCI.

Purpose: Frame Running is an adapted community-based exercise option for people with moderate-to-severe walking impairments. This mixed-methods study aimed to examine the feasibility of 1) community-based Frame Running by young people with moderate-to-severe walking impairments and 2) conducting future studies on the impact of Frame Running on functional mobility and cardiometabolic disease risk factors.

Materials and Methods: Weekly training sessions and data collection occurred in two sites. Quantitative data were collected at baseline, and after 12 (both sites) and 24 (one site) weeks of training, followed by interviews or focus groups. Consent and retention rates, attendance and outcome measure completion rates were calculated. Qualitative data were analysed abductively using concurrent inductive and deductive thematic content analysis. Data for the assessments at baseline, 12 and 24 weeks were available for 23, 15 and 5 participants respectively.

Results: Participants were aged 5-25 with most diagnosed with cerebral palsy (GMFCS II-IV). Consent, intervention drop-out and adherence rates were 55%, 17% and 83% respectively with no serious adverse events. Outcome measure completion rates ranged between 60% and 98%. Themes related to facilitators to participating in Frame Running were mostly identified in the personal and social domains with barriers more common in the environmental and policy domains.

Conclusions: The study results support the existing evidence that Frame Running is a safe and acceptable community-based exercise option for those with moderate-to-severe walking impairments. Themes identified in personal, social, environmental and policy domains can guide the implementation of community-based Frame Running participation. Our feasibility data can inform the design of future definitive studies.
