Purpose: This research paper examines how contouring of a wheelchair seating base can help prevent pressure sores by distributing pressure over the buttocks. Contouring wheelchair cushioning is already done to some extent and has proved to be beneficial for pressure distribution. We researched the effect of contouring the seating base, and whether contouring the seating base affects effectiveness in pressure distribution and perceived discomfort.

Materials & methods: 13 healthy participants performed a within-subject experiment with three differ- ently contoured seating bases. Perceived comfort and seating pressure were measured for each condition.
Results: Results indicate that a more contoured base is positive for both comfort and increased pressure distribution.

Conclusions: Contoured seating bases can provide increased comfort and improved pressure distribution over flat seating bases. Future research should examine the effect of contouring on stability, as well as compare the effects of contoured seating bases and contoured cushions.

Purpose

FindMyApps is a web-based selection-tool and errorless learning training program to help people with mild dementia/Mild Cognitive Impairment (MCI) and caregivers find user-friendly apps. In preparation of a definitive trial, the impact and feasibility of the FindMyApps intervention on self-management and engagement in meaningful activities, including social participation, was explored.

Materials and methods

An exploratory pilot randomised controlled trial (trial registration approval number: NL7210) with pre/post measurements was conducted with community-dwelling people with mild dementia/MCI and their caregivers (n = 59) in the Netherlands. Dyads in the experimental group (n = 28) received training to use the tablet and FindMyApps, and the errorless learning method was taught to their caregivers. Control group dyads (n = 31) received a tablet (without FindMyApps), instructions on tablet-use and links to dementia-friendly apps. Validated instruments were used to assess person with dementia’s self-management, meaningful activities and social participation, caregiver’s sense of competence and both their quality of life.

Results and conclusions

No statistical significant group differences on the outcomes were found. Small to moderate effect-sizes in favour of the FindMyApps group were found for self-management and social participation. Caregivers tended to have more positive care experiences. Subgroup analyses showed that people older than 70 benefitted more from FindMyApps regarding self-management and higher educated people benefitted more regarding social participation. FindMyApps is feasible for the target group and may have potential to improve self-management and social participation. For a future definitive effectiveness trial a larger sample size is recommended, as well as taking into account the possible impact of education and age.

Purpose

The purpose of this study was to clarify whether the novel lateral transfer assist robot facilitates easier transfers compared with a wheelchair in post-stroke hemiparesis patients.

Methods

This cross-sectional study enrolled 20 post-stroke hemiparesis patients, and the task difficulty of transfers was compared between a wheelchair and lateral transfer assist robot. All participants were asked to transfer from either wheelchair or lateral transfer assist robot to a platform table and back. The primary outcome was the transfer score of the Functional Independence Measure. The secondary outcome was the time required for transfer.

Results

The transfer score of the Functional Independence Measure was significantly higher with lateral transfer assist robot than with wheelchair (p < .001). The transfer times from these devices to a platform table and back showed no significant differences (to device from platform table: 7.8 s, lateral transfer assist robot vs 7.6 s, wheelchair, p > .05: device to platform table: 7.1 s, lateral transfer assist robot vs 8.0 s, wheelchair, p > .05).

Conclusions

Transfer with a lateral transfer assist robot is easier than with wheelchair and facilitates independence in post-stroke hemiparesis patients.

Purpose

Orientation and Mobility (O&M) professionals teach people with low vision or blindness to use specialist assistive technologies to support confident travel, but many O&M clients now prefer a smartphone. This study aimed to investigate what technology O&M professionals in Australia and Malaysia have, use, like, and want to support their client work, to inform the development of O&M technologies and build capacity in the international O&M profession.

Materials and Methods

A technology survey was completed by professionals (n = 36) attending O&M workshops in Malaysia. A revised survey was completed online by O&M specialists (n = 31) primarily in Australia. Qualitative data about technology use came from conferences, workshops and interviews with O&M professionals. Descriptive statistics were analysed together with free-text data.

Results

Limited awareness of apps used by clients, unaffordability of devices, and inadequate technology training discouraged many O&M professionals from employing existing technologies in client programmes or for broader professional purposes. Professionals needed to learn smartphone accessibility features and travel-related apps, and ways to use technology during O&M client programmes, initial professional training, ongoing professional development and research.

Conclusions

Smartphones are now integral to travel with low vision or blindness and early-adopter O&M clients are the travel tech-experts. O&M professionals need better initial training and then regular upskilling in mainstream O&M technologies to expand clients’ travel choices. COVID-19 has created an imperative for technology laggards to upskill for O&M tele-practice. O&M technology could support comprehensive O&M specialist training and practice in Malaysia, to better serve O&M clients with complex needs.

Purpose: 

The aim of this study was to identify factors that influence the perceived stigma of two assistive devices for visual impairment, namely the white cane and smart glasses.

Method: 

Face-to-face semi-structured interviews with eight European students were conducted to probe their experiences and knowledge related to disability, assistive technology, visual impairment, as well as handheld and wearable devices.

Results: 

Close relationships with disabled people seems to have a positive influence on participants perceptions about stigma, disability, and assistive technology. Academic background seems to not have any influence. The aesthetics of assistive devices was observed as an important factor that influences the adoption or abandonment of the device.

Conclusion: 

Device without negative symbolism but with modern aesthetics (smart glasses) were positively accepted by the participants than the device with traditional aesthetics and symbolisms of visual impairment (white cane). Designers should, therefore, consider aesthetics in addition to functionality in order to avoid the perceived stigma, thereby reducing the chances of device abandonment.

Introduction: 

Sensor-feedback systems can be used to support people after stroke during independent practice of gait. The main aim of the study was to describe the user-centred approach to (re)design the user interface of the sensor feedback system “Stappy” for people after stroke, and share the deliverables and key observations from this process.

Methods: 

The user-centred approach was structured around four phases (the discovery, definition, development and delivery phase) which were fundamental to the design process. Fifteen participants with cognitive and/or physical limitations participated (10 women, 2/3 older than 65). Prototypes were evaluated in multiple test rounds, consisting of 2–7 individual test sessions.

Results: 

Seven deliverables were created: a list of design requirements, a personae, a user flow, a low-, medium- and high-fidelity prototype and the character “Stappy”. The first six deliverables were necessary tools to design the user interface, whereas the character was a solution resulting from this design process. Key observations related to “readability and contrast of visual information”, “understanding and remembering information”, “physical limitations” were confirmed by and “empathy” was additionally derived from the design process.

Conclusions: 

The study offers a structured methodology resulting in deliverables and key observations, which can be used to (re)design meaningful user interfaces for people after stroke. Additionally, the study provides a technique that may promote “empathy” through the creation of the character Stappy. The description may provide guidance for health care professionals, researchers or designers in future user interface design projects in which existing products are redesigned for people after stroke.

Introduction: 

Wheelchair casters fail frequently in the field causing multiple user consequences and wheelchair breakdowns. To inform caster design improvement, there exists no validated tools that can collect caster failures. This need motivated the development of a user-reported, caster failure inspection tool (C-FIT).

Methods: 

To develop C-FIT, a multistep design and testing approach was used which included face validity testing, test-retest reliability testing and expert review. Reliability testing was conducted with two independent cohorts of wheelchair professionals who inspected caster failures physically and online through pictures. The tool was revised based on testing outcomes and expert feedback. For preliminary data collection and evaluating usability, C-FIT was piloted at wheelchair service centers in Scotland, Indonesia and Mexico.

Results: 

Caster failure items reported in the literature were screened to develop the initial list of C-FIT items. Face validity testing conducted through surveys with wheelchair experts (n = 6) provided 14 items for C-FIT inclusion. The test-retest reliability was found to be high for 10 items with physical failure inspections (n = 12). For each of these items, 75% or more participants had substantial to almost perfect agreement scores (κ = 0.6–1.0). Lower reliability scores were found with online failure inspections (n = 11). C-FIT received positive usability feedback from study participants and data collectors in the field. Pilot field data (n = 31) included comprehensive details about failures useful for manufacturers, designers and researchers to improve caster designs.

Conclusions: 

The C-FIT tool developed in this study has substantial reliability and can be used for documenting caster failures at wheelchair service centers.

Purpose: Reading and writing applications (with text-to-speech, TTS and speech-to-text, STT functions), used as assistive technology (AT) for students with reading difficulties are increasingly used in education, however, research has not sufficiently enough evaluated its potential. The purpose of this study was to explore how assistive reading and writing applications were perceived to function with regard to students’ possibilities to assimilate (i.e., “read”) and communicate (i.e., “write”) text.

Methods: Following a six-week app intervention, this follow-up survey contained 54 special education teachers’ perceptions of how the use of apps impacted student motivation, learning, and its usability in special education. A total of 59 students with reading difficulties from Grade 4, Grade 8 and from high school, were assessed. Analyses included quantitative and qualitative analyses of teachers’ responses and written material.

Results: The results showed individual differences in how teachers perceived app usage for text-interaction purposes, including how app usage affected student motivation and autonomy for text-based learning. Eighty-two per cent of the younger and forty-seven per cent of older students continued to use the technology after the intervention, but in various degrees.

Conclusions: Based on these findings, students with reading difficulties seem to be able to use AT in order to assimilate text (i.e., to read) and to communicate text (i.e., to write), and, thus, AT has the potential to promote participation in regular education. Future research should focus on how to customize assistive technology support in order to better utilize the potential.

Assistive technology (AT) is an essential facilitator of independence and participation, both for people living with the effects of disability and/or non-communicable disease, as well as people aging with resultant functional decline. The World Health Organization (WHO) recognizes the substantial gap between the need for and provision of AT and is leading change through the Global Cooperation on Assistive Technology (GATE) initiative. Showcasing innovations gathered from 92 global researchers, innovators, users and educators of AT through the WHO GREAT Summit, this article provides an analysis of ideas and actions on a range of dimensions in order to provide a global overview of AT innovation. The accessible method used to capture and showcase this data is presented and critiqued, concluding that “innovation snapshots” are a rapid and concise strategy to capture and showcase AT innovation and to foster global collaboration.
