The impact on employment and education of caregiving for a family member with young onset dementia: A scoping review

Young-onset dementia (YOD) affects individuals under 65 years of age, often leading to loss of employment and independence. Families provide increasing levels of care to family members with YOD, resulting in changes to their daily lives, including their occupational pursuits. This review examines evidence of the occupational implications for family members who provide care to a family with YOD to identify: (i) the influence and impact caregiving tasks and responsibilities have on employment, volunteering, and education, and (ii) caregiver, and caregiving situation factors associated with changes in employment, volunteering, and education. A scoping review was performed using eight electronic databases. Included articles were narratively synthesized using a thematic analysis. Sixteen studies met the inclusion criteria and were included for review. The over-arching (main) theme of 'decision-making' was identified, with family members required to make choices about their own occupational goals and roles to be able to provide care to family living with YOD. The outcomes of these decisions are dynamic and changeable across the caregiving trajectory. Three caregiving factors influence decision-making: (1) Implications of Combining Caregiving and Occupations, (2) Altered Identity (3) Strategies to Support Caregivers of Individuals Living with YOD. A fourth theme was also identified 'Guidance for Researchers To Support Caregivers'. There is a scarce body of literature examining the influence caregiving has on occupational outcomes for the YOD caregiver population. Much of this work is descriptive and lacks focus on the implications, particularly long-term impacts. This review provides a foundational guide for future research and practices to support YOD family caregivers to obtain and sustain occupations.

You've Got E-Mail: A Pilot Study Examining the Feasibility and Impact of a Group-Based Technology-Training Intervention Among Older Adults Living in Residential Care

Older adults living in residential care often experience challenges in sustaining meaningful social relationships, which can result in compromised health and well-being. Online social networking has the potential to mitigate this problem, but few studies have investigated its implementation and its effectiveness in maintaining or enhancing well-being. This pilot study used a cluster-randomized pre-post design to examine the feasibility of implementing a 12-week group-based technology-training intervention for older adults (n = 48) living in residential care by exploring how cognitive health, mental health, and confidence in technology were impacted. Analysis of variance revealed significant increases in life satisfaction, positive attitudes toward computer use, and self-perceived competence among participants who received the intervention, but increased depressive symptoms for the control group. These findings suggest that, despite challenges in implementing the intervention in residential care, group-based technology training may enhance confidence among older adults while maintaining or enhancing mental health.

What happens when people develop dementia whilst working? An exploratory multiple case study

PURPOSE

This study is an in-depth exploration of the unfolding experiences of five persons who developed dementia while still in paid work/employment, and of their significant others. Namely, we explore how they experienced the actions and decisions taken with respect to work, and what the consequences meant to them.

METHODS

A qualitative longitudinal case study design with multiple cases was used, including five participants with dementia and significant others of their choice. Interviews were undertaken longitudinally and analysed with the Formal Data-Structure Analysis approach.

RESULTS

The joint analysis resulted in two intertwined themes: 1) The significance and consequences of a dementia diagnosis: a double-edged trigger, and 2) Sensemaking and agency. The prevalent images of what dementia is, who can/cannot get it and what it will bring, were revealed as the critical aspects. Having the opportunity to make sense of what has happened and participate in decision-making, contributed decisively to the participants' experiences.

CONCLUSIONS

Findings illustrate how a dementia diagnosis is alien in work-life, but once diagnosed, it may trigger self-fulfiling expectations based upon stereotypical understanding of dementia. A shift is needed from a deficit-focused perspective, to viewing people with dementia as citizens capable of agency.

Virtual reality as a tool to explore multisensory processing before and after engagement in physical activity

Introduction

This pilot study employed a non-randomized control trial design to explore the impact of physical activity within a virtual reality (VR) environment on multisensory processing among community-dwelling older adults.

Methods

The investigation compared both chronic (over 6 weeks) and acute effects of VR-based physical activity to a reading control group. The evaluation metrics for multisensory processing included audiovisual response time (RT), simultaneity judgments (SJ), sound-induced flash illusion (SIFI), and temporal order judgments (TOJ). A total of 13 older adults were provided with VR headsets featuring custom-designed games, while another 14 older adults were assigned to a reading-based control group.

Results

Results indicated that acute engagement in physical activity led to higher accuracy in the SIFI task (experimental group: 85.6%; control group: 78.2%; p = 0.037). Additionally, both chronic and acute physical activity resulted in quicker response times (chronic: experimental group = 336.92; control group = 381.31; p = 0.012; acute: experimental group = 333.38; control group = 383.09; p = 0.006). Although the reading group showed a non-significant trend for greater improvement in mean RT, covariate analyses revealed that this discrepancy was due to the older age of the reading group.

Discussion

The findings suggest that immersive VR has potential utility for enhancing multisensory processing in older adults. However, future studies must rigorously control for participant variables like age and sex to ensure more accurate comparisons between experimental and control conditions.

Co-design of a digital app "WhatMatters" to support person-centred care: A critical reflection

BACKGROUND

People with dementia often do not receive optimal person-centred care (PCC) in care settings. Family members can play a vital role as care partners to support the person with dementia with their psychosocial needs. Participatory research that includes the perspectives of those with lived experience is essential for developing high-quality dementia care and practices.

OBJECTIVE

Throughout 2021-2022, a mobile app, called WhatMatters, was co-developed to provide easy-to-access and personalised support for people with dementia in hospitals and long-term care homes, with input from patients/residents, family partners and healthcare staff. This article discusses and critically reflects on the experiences of patients/residents, family partners, and healthcare staff involved in the co-design process.

METHODS

For the app development, we applied a participatory co-design approach, guided by a User Experience (UX) model. The process involved co-design workshops and user testing sessions with users (patients/residents, family partners, healthcare staff) to co-develop the WhatMatters prototype. We also conducted focus groups and one on one interviews with staff and caregiver participants to explore their experiences. Our research team, which also included patient partners, took part in regular team meetings during the app's development, where we discussed and reflected on the co-design process. Reflexive thematic analysis was performed to identify themes that represent the challenges and rewarding experiences of the users involved in the co-design process, which guided our overall reflective process.

FINDINGS

Our reflective analysis identified five themes (1) clarifying the co-design process, (2) ensuring inclusive collaborations of various users, and (3) supporting expression of emotion in a virtual environment, (4) feeling a sense of achievement and (5) feeling valued.

IMPLICATIONS

WhatMatters offers potential for providing personally relevant and engaging resources in dementia care. Including the voices of relevant users is crucial to ensure meaningful benefits for patients/residents. We offer insights and lessons learned about the co-design process, and explore the challenges of involving people with lived experiences of dementia in co-design work, particularly during the pandemic.

Ethical principles for infodemiology and infoveillance studies concerning infodemic management on social media

Big data originating from user interactions on social media play an essential role in infodemiology and infoveillance outcomes, supporting the planning and implementation of public health actions. Notably, the extrapolation of these data requires an awareness of different ethical elements. Previous studies have investigated and discussed the adoption of conventional ethical approaches in the contemporary public health digital surveillance space. However, there is a lack of specific ethical guidelines to orient infodemiology and infoveillance studies concerning infodemic on social media, making it challenging to design digital strategies to combat this phenomenon. Hence, it is necessary to explore if traditional ethical pillars can support digital purposes or whether new ones must be proposed since we are confronted with a complex online misinformation scenario. Therefore, this perspective provides an overview of the current scenario of ethics-related issues of infodemiology and infoveillance on social media for infodemic studies.

Hallway Gait Monitoring System Using an In-Package Integrated Dielectric Lens Paired with a mm-Wave Radar

This paper presents a novel hallway gait extraction system that enables an individual's spatiotemporal gait parameter extraction at each gait cycle using a single FMCW (Frequency Modulated Continuous Wave) radar. The purpose of the proposed system is to detect changes in gait that may be the signs of changes in mobility, cognition, and frailty, particularly for older adults in retirement homes. We believe that one of the straightforward applications for gait monitoring using radars is in corridors and hallways, which are commonly available in most retirement and long-term care homes. To achieve in-corridor coverage, we designed an in-package hyperbola-based lens antenna integrated with a radar module package empowered by our fast and easy-to-implement gait extraction method. We validated system functionality by capturing spatiotemporal gait values (e.g., speed, step points, step time, step length, and step count) of people walking in a hallway. The results achieved in this work pave the way to explore the use of stand-alone radar-based sensors in long hallways in retirement apartment buildings or individual's homes for use in day-to-day long-term monitoring of gait parameters of older adults.

TRANSITIONS EXPERIENCED BY PEOPLE DIAGNOSED WITH DEMENTIA WHILE IN THE WORKFORCE

Dementia is a progressive, irreversible neurological disorder that causes changes in cognitive function and behaviour. While at least 5% of people who develop dementia every year are under the age of 65, dementia in the workplace is currently not well recognised or supported. The changes associated with dementia present multiple challenges for individuals who wish to continue with their employment. Many lose their positions before receiving a diagnosis, whilst others take sick or disability leave or early retirement. The process of understanding what is happening and coping with this new situation is highly individualistic and involves several transitions. The MCI@work project is an international initiative taking place in Canada, Finland, and Sweden where we examine these transitions through the personal narratives of individuals who have either currently or recently gone through the experience of developing dementia whilst in the workforce. From these data, we have developed a framework for understanding the transitions experienced by people who develop dementia whilst in the workforce. The aim is to assist individuals and their employers to better understand the needs of people living and working dementia as well as engage in appropriate actions that support choices and dignified transitions either within the context of employment or out of the workforce.

DE-RISKING THE EMPLOYER-EMPLOYEE RELATIONSHIP WHEN WORKERS HAVE MILD COGNITIVE IMPAIRMENT OR YOUNG ONSET DEMENTIA

The employee-employer relationship is one that is well established in law and involves a contract between a worker who performs the work, and an employer who determines when, how and where the work is done. Many countries have introduced legislation that helps guide employee-employer behavior when workers’ performance of their duties is disrupted by illness or disability, such as mild cognitive impairment or young onset dementia (MCI|YOD). At any one time, about 8-12% of the workforce is off due to occupational or non-occupational work injury or illness with direct disability and absence costs projected about 7% of payroll in 2000. Drawing from data gathered in a systematic literature review and case study, this paper determined that uncertainty and risk influence employer-employee relationships when workers are identified with MCI|YOD. Employers’ industry context, size and corporate values influence their “integrated risk management” approach to workers with MCI|YOD, and early intervention is considered key to managing financial and liability risk. In contrast, progressive onset, delayed diagnosis, stigma, privacy concerns, workplace uncertainty, and lack of information may delay employee disclosure, a common employee risk mitigation strategy. We conclude by considering strategies to de-risk relationships between workers with MCI|YOD and employers using dual process theory to understand intuitive and rational decisions in the context of the disability management process.

"Virtual care yes, but it has to be in addendum": A Qualitative Study of COVID-19's Impact on Older Adults' Perceptions of Virtual Care

Background

In response to the COVID-19 pandemic, older adults worldwide have increasingly received health care virtually, and health care organizations and professional bodies have indicated that virtual care is “here to stay.” As older adults are the highest users of the health care system, virtual care implementation can have a significant impact on them and may pose a need for additional support.

Objective

This research aims to understand older adults’ perspectives and experiences of virtual care during the pandemic.

Methods

As part of a larger study on older adults’ technology use during the pandemic, we conducted semistructured interviews with 20 diverse older Canadians (mean age 76.9 years, SD 6.5) at 2 points: summer of 2020 and winter/early spring of 2021. Participants were asked about their technology skills, experiences with virtual appointments, and perspectives on this type of care delivery. Interviews were digitally recorded and transcribed. A combination of team-based and framework analyses was used to interpret the data.

Results

Participants described their experiences with both in-person and virtual care during the pandemic, including issues with accessing care and long gaps between appointments. Overall, participants were generally satisfied with the virtual care they received during the pandemic. Participants described the benefits of virtual care (eg, increased convenience, efficiency, and safety), the limitations of virtual care (eg, need for physical examination and touch, lack of nonverbal communication, difficulties using technology, and systemic barriers in access), and their perspectives on the future of virtual care. Half of our participants preferred a return to in-person care after the COVID-19 pandemic, while the other half preferred a combination of in-person and virtual services. Many participants who preferred to access in-person services were not opposed to virtual care options, as needed; however, they wanted virtual care as an option alongside in-person care. Participants emphasized a need for training and support to be meaningfully implemented to support both older adults and providers in using virtual care.

Conclusions

Overall, our research identified both perceived benefits and perceived limitations of virtual care, and older adult participants emphasized their wish for a hybrid model of virtual care, in which virtual care is viewed as an addendum, not a replacement for in-person care. We recognize the limitations of our sample (small, not representative of all older Canadians, and more likely to use technology); this body of literature would greatly benefit from more research with older adults who do not/cannot use technology to receive care. Findings from this study can be mobilized as part of broader efforts to support older patients and providers engaged in virtual and in-person care, particularly post–COVID-19.

Immersive Virtual Reality Exergames for Persons Living With Dementia: User-Centered Design Study as a Multistakeholder Team During the COVID-19 Pandemic

BACKGROUND

Advancements in supporting personalized health care and well-being using virtual reality (VR) have created opportunities to use immersive games to support a healthy lifestyle for persons living with dementia and mild cognitive impairment (MCI). Collaboratively designing exercise video games (exergames) as a multistakeholder team is fundamental to creating games that are attractive, effective, and accessible.

OBJECTIVE

This research extensively explores the use of human-centered design methods that involve persons living with dementia in long-term care facilitates, exercise professionals, content developers, game designers, and researchers in the creation of VR exergames targeting physical activity promotion for persons living with dementia/MCI.

METHODS

Conceptualization, collaborative design, and playtesting activities were carried out to design VR exergames to engage persons living with dementia in exercises to promote upper limb flexibility, strength, and aerobic endurance. We involved a total of 7 persons living with dementia/MCI, 5 exercise professionals, 5 community-dwelling older adults, a VR company for content creation, and a multidisciplinary research team with game designers, engineers, and kinesiology experts.

RESULTS

An immersive VR exergame called Seas the Day was jointly designed and developed and it is freely available to be played in state-of-the-art VR headsets (Oculus Quest 1, 2). A model for the triadic interaction (health care institution, industry partner, academia) is also presented to illustrate how different stakeholders contribute to the design of VR exergames that consider/complement complex needs, preferences, and motivators of an underrepresented group of end users.

CONCLUSIONS

This study provides evidence that a collaborative multistakeholder design results in more tailored and context-aware VR games for persons living with dementia. The insights and lessons learned from this research can be used by others to co-design games, including remote engagement techniques that were used during the COVID-19 pandemic.

Seas the day: Co-designing immersive virtual reality exergames with exercise professionals and people living with dementia

BACKGROUND

Physical activity (PA) is associated with physical and cognitive benefits among people living with dementia or mild cognitive impairment (PLWD/MCI) and is a meaningful activity that can improve their confidence in everyday life. Exercising in virtual reality environments (VR Exergame) is becoming an increasingly feasible and enjoyable way to promote PA and well-being in PLWD/MCI. Although co-design can significantly improve the design of technology, it is rarely done with PLWD/MCI. This study uses participatory design methods and collaborative approaches to involve key stakeholders to develop and test a VR Exergame "Seas the Day", a novel solution targeting PLWD/MCI well-being.

METHODS

A multi-stage, user-centered co-design approach was used to custom-build VR Exergames tailored to the unique needs and abilities of PLWD/MCI based on a first generation of the prototype that was previously developed and tested with PLWD/MCI. This paper describes the next iteration of the prototype. Processes included concept ideation and brainstorming activities, iterative prototyping, and playtesting/input/feedback sessions with key stakeholders (PLWD/MCI, exercise professionals, engineers, VR game designers, content developers).

RESULTS

The multidisciplinary and collaborative design process occurred over 15 months (overlapping with COVID-19 pandemic) with 7 PLWD/MCI (6 females; M=81.3 years) and 9 exercise professionals (7 females; M=38.1 years) to date. The game was designed to target movements identified by exercise professionals and researchers (aerobic exercises, range of motion, seated-balance, quick response to stimuli) and is structured in three exercise stages (warm-up, conditioning, cool-down). To ensure safety of participants while using VR headsets, only seated upper-limb exercises were targeted. Stakeholder feedback regarding game mechanics, aesthetics, and visual/auditory cues were gathered during brainstorming and playtesting sessions and implemented into specific game-related scenarios (tai-chi, rowing, fishing).

CONCLUSION

We presented the process, outcomes, and challenges of adopting a participatory/collaborative approach with multiple stakeholder groups to co-design VR Exergames tailored to PLWD/MCI. Next steps will include a mixed-method evaluation of the VR Exergames among community-dwelling older adults and PLWD/MCI in retirement communities and long-term care to evaluate: i) feasibility and acceptability of use, ii) game user experience, iii) barriers/facilitators to uptake of VR Exergames; and iv) inform/validate VR Exergames gameplay metrics reflective of cognitive and motor performance.

Employers ’ Response to Workers With Progressive Cognitive Impairment: A Review of Policy in Canada

Longer lifespans, the gig economy, eligibility for government pensions, and more testing for age-related cognitive changes, increase the potential for workers developing mild cognitive impairment and/or early onset dementia (MCI|EOD) “on the job”. This critical analysis assesses Canada’s policy environment for employers when employees are diagnosed with MCI|EOD. Our search for policy literature included: a scoping review of academic literature involving Canadian-focused articles, and countries where novel or innovative policy had been evaluated and published; a search for Canadian court judgements and tribunal decisions; and a grey literature search in both Canadian and international sources, as innovation will often happen “at the margin” and updated policy may take years to be enacted and formalized. We used participatory research to obtain feedback from a broad group of stakeholders including employers, industry, professional organizations, and government, as well as people living with MCI/dementia, to ensure outputs were reflective of current policy. We found that: 1) Canadian federally-regulated employers are governed by similar Acts & Codes as the provinces and territories, with some notable exceptions, 2) Disability discrimination and accommodation case law in Canada is settled, however there are few cognitive impairment cases to provide specific guidance, 3) Scant empirical research in the scientific literature addresses policy that incents employers to build workspaces for employees with MCI|EOD that help them stay on the job longer. We conclude that engaging with employers to better understand their needs will help policy-makers to support them build workspaces that encourage productive engagement of all workers.

Exploring the Impact of COVID-19 on Family Caregivers of Persons Living With Dementia in the Community

COVID-19 public health measures have significantly impacted persons living with dementia (PLWD) and family caregivers (FCGs). Given the restrictions on in-person services, many PLWD were not able to access their usual supports and activities, resulting in FCGs stepping in to support exercise, leisure, socialization, spirituality, and activities of daily living. At the same time, FCGs’ own support networks were significantly reduced or no longer available. We conducted in-depth qualitative interviews with 20 FCGs of PLWD in the community to explore the impact of COVID-19 on their well-being. Data were analyzed using thematic analysis. Caregiving during COVID-19 was described as ‘draining’ and ‘stressful’, with the support needs of PLWD increasing at a time when fewer supports were available. Reaching out to others, using technology, and setting boundaries were strategies FCGs used to cope. Despite the considerable impacts of COVID-19, FCGs of PLWD demonstrated their resilience in supporting themselves and their PLWD.

Employers’ Response to Workers With Progressive Cognitive Impairment: A Systematic Literature Review

An aging workforce increases the risk of workers experiencing cognitive decline that may lead to a diagnosis of mild cognitive impairment or early onset dementia (MCI|EOD) while still employed. This systematic review explores the use of technologies (defined as any methods, processes, software, hardware or equipment) deployed by employers to accommodate, or build sustainable workspaces for, workers diagnosed with MCI|EOD. After screening 3,860 titles/abstracts and 67 full text reviews, we identified and analyzed eight articles that met our inclusion criteria. We found that: 1) The existing literature almost exclusively focuses on employees’ perspectives on the quality of work life when diagnosed with MCI|EOD, 2) Negative workspace culture toward employees’ cognitive decline, and the variability of disease onset and progression, may account for low employer awareness, 3) Employer responses focus on mitigation of risk associated with workers’ impairment. While this review demonstrates there is scant research exploring employers’ perspectives on employees diagnosed with MCI|EOD, there is even less that explores technologies designed to specifically address employers’ needs and challenges. Technology will increasingly facilitate early identification of progressive neuro-cognitive disorders, and tools to help employers respond to an employee’s MCI|EOD disclosure as a disability accommodation rather than a terminal performance management challenge. Empathic research, that engages organizations in the process of understanding the value of affordable, employer-side technologies that help build diverse, sustainable, productive workspaces is critical to a foundational understanding of our aging workforce and accommodating workers who develop MCI|EOD while still employed.

Impact of COVID‐19 on family care partners of persons with dementia in long‐term care settings in Canada: Not a ‘one‐size‐fits‐all’ story

Background

COVID‐19 has been devastating for older adults, particularly residents in long‐term care/retirement (LTC) homes. In an effort to curb the transmission of COVID‐19, public health measures have been put in place in many LTC homes, including mask wearing, physical distancing, and visitor restrictions. As the pandemic passes the one‐year mark, we are starting to understand the profound impacts of COVID‐19 and the corresponding public health measures on persons living with dementia (PLWD) and their family care partners (CPs). This research is part of a larger study exploring the impact of COVID‐19 on the wellbeing and social connections of PLWD and CPs. In this presentation, findings from qualitative interviews conducted with CPs of PLWD in LTC homes are shared.

Methods

The overall study used an intrinsic case study design, involving survey and interview data. Following completion of a survey, participants were invited to participate in an in‐depth qualitative interview. Interviews were conducted by phone or online, transcribed verbatim, and analyzed using thematic analysis.

Results

Eighteen CPs were interviewed. The impact of visitor restrictions varied between LTC homes and changed over the course of the pandemic, which was extremely challenging for CPs. At homes with visitor restrictions, the inability to visit family members with dementia was described as stressful, unfair, and frustrating. CPs stressed the importance of being able to visit their relatives, and ensuring their family members had regular social interaction to support their physical, social and emotional wellbeing. Even when CPs could visit, masks and physical distancing made communication with some PLWD challenging. Visitor policies also influenced perceptions of care. Some CPs felt that the needs of their family members with dementia were being met by the home, while others weren’t sure because CPs weren’t in the homes to assist staff and provide support to their family members with dementia.

Conclusion

While COVID‐19 and the pandemic restrictions have been difficult for all CPs of persons with dementia in LTC, for some it has been agonizing. Understanding these varied experiences can help inform the development of individually‐tailored resources to better support the wellbeing of CPs.

Working towards inclusion: Creating technology for and with people living with mild cognitive impairment or dementia who are employed

Earlier diagnosis and longer working careers is resulting in more individuals being identified as having Mild Cognitive Impairment or Early Onset Dementia (MCI/EOD) when they are still in the workforce. While there is growing interest in the dementia research community and beyond to develop technologies to support people with dementia, the use of technology for and by people with MCI/EOD in the workplace has had very little attention. This paper presents a two-part study involving interviews and participatory sessions to begin to understand the workplace experiences and the role of technology among people living with MCI/EOD. We present our findings from working with seven people with MCI/EOD and two care partners to explore technology design. Our results indicate several similarities as well as a few differences between MCI/EOD and later-onset dementia with respect to challenges using technology and design considerations for supporting engagement and use of technology. Lessons learned through the process of working with people with MCI/EOD through participatory methods is presented along with recommendations to foster an inclusive, respectful, and empowering experience for participants with MCI/EOD.

In Their Own Words: How COVID-19 Has Impacted the Well-Being of Persons Living with Dementia in the Community

COVID-19 has had a devasting impact on older adults in Canada, including persons living with dementia. This intrinsic case study sought to understand the perceptions of persons living with dementia regarding how COVID-19 has impacted their well-being. Ten persons living with dementia participated in in-depth qualitative interviews about their experience with COVID-19. Using thematic analysis, four themes were identified: (1) expressing current and future concerns; (2) social connections and isolation; (3) adapting to change and resilience through engagement and hope; and (4) we're not all the same: reflecting individual experiences of the pandemic. Results highlight that while COVID-19 contributed to isolation, concerns, and frustrations, persons with dementia also demonstrated adaptation and resilience. This study reinforced that persons with dementia and their responses to challenges are unique. Therefore, interventions to support persons with dementia must also be individualized to each person's abilities and circumstances.

Load Distribution Analysis for Weight and Ballistocardiogram Measurements of Heart Failure Patients using a Bed Scale

Ballistocardiogram (BCG) is an emerging tool with the potential to monitor heart failure (HF) patients. A close association of the weight to the BCG as an intermediate signal source requires a careful design, where events such as saturation of the weight signal can result in the loss of the BCG. This work closely examined the factors around the weight while load cells placed under each support of a bed collected the BCG (e.g., body weight, distribution over the four supports of the bed). Following the calibration of weights based on the location of the polls, the study examined the ratios of loads in head-foot and lateral directions. The head-foot ratio was also correlated to the height. Twelve non-obese HF patients were recruited, and the weight and BCG were appropriately measured, where the average error of the weight measurements was 0.45 ± 0.30%. The mean ratio of the loads between head to foot sensors was 3.2 ± 0.7 with a maximum ratio of 4.5, showing that the head-ward sensors supported greater body weight. The ratio of the loads between the right to left sensors was 1.2 ± 0.1. The height and the head-to-foot ratio had an inverse correlation (r = 0.52). Based on the analysis, the head-ward sensors should have a higher capacity of up to three times that of the foot-ward sensors to prevent any signal saturation. Mobility issues were observed in some subjects, attributing to the lateral imbalance. These novel findings based on the end-users (i.e., HF population) may allow better allocation of conditioning resources to obtain the BCG (e.g., optimally adjusted sensitivity).

Self-initiated management approaches in everyday occupations used by people with acquired cognitive impairment

BACKGROUND

Striving to cope with day-to-day challenges is a basic human behaviour. Self-initiated management approaches provide a resource that has yet to be discovered and systematically used in occupational therapy practice. This resource might be especially important for people with dementia who are less likely to adopt management approaches initiated by others.

AIMS/OBJECTIVES

Based on the findings of former studies on management and problem-solving actions among people with cognitive impairment, this article aims to identify and categorize the study participants' self-initiated management approaches and how these may be manifested in strategies in everyday occupations.

MATERIAL AND METHODS

The study utilized a form of meta-synthesis; an aggregated analysis, where findings from 11 studies published 2004-2020 were compared and categorized, incorporating the views of participants with dementia/mild cognitive impairment, or acquired brain injury.

RESULTS

Thirty strategies were identified and grouped into seven categories of management approaches, used in a variety of everyday occupations and situations. A majority of the strategies were found in both populations, suggesting that management approaches are more similar than different across populations with cognitive impairment.

CONCLUSIONS AND SIGNIFICANCE

Attending to the rich variation of self-initiated management approaches/strategies among persons with cognitive impairment offers possibilities for developing occupational therapy interventions.

Immersive virtual reality exergames to promote well-being of community-dwelling older adults: a mixed-methods pilot study protocol (Preprint)

Background

Despite the proven benefits of exercise in older adults, challenges such as access and motivation can deter their engagement. Interactive virtual reality (VR) games combined with exercise (exergames) are a plausible strategy to encourage physical activity among this population. However, there has been little research on the feasibility, acceptability, and potential benefits of deploying at-home VR exergames among community-dwelling older adults.

Objective

The objectives of this study are to estimate the feasibility, usability, and acceptability of a co-designed VR exergame in community-dwelling older adults; examine intervention feasibility and assessment protocols for a future large-scale trial; and provide pilot data on outcomes of interest (physical activity, exercise self-efficacy, mood, cognition, perception, and gameplay metrics).

Methods

The study will be a remote, 6-week intervention comprising an experimental and a control group. A sample of at least 12 community-dwelling older adults (with no or mild cognitive impairment) will be recruited for each group. Both groups will follow the same study procedures and assessment methods. However, the experimental group will engage with a co-designed VR exergame (Seas The Day) thrice weekly for approximately 20 minutes using the Oculus Quest 2 (Facebook Reality Labs) VR headset. The control group will read (instead of playing Seas The Day) thrice weekly for approximately 20 minutes over the 6-week period. A mixed methods evaluation will be used. Changes in physical activity, exercise self-efficacy, mood, cognition, and perception will be compared before and after acute data as well as before and after the 6 weeks between the experimental (exergaming) and control (reading) groups. Qualitative data from postintervention focus groups or interviews and informal notes and reports from all participants will be analyzed to assess the feasibility of the study protocol. Qualitative data from the experimental group will also be analyzed to assess the feasibility, usability, and acceptability of at-home VR exergames and explore perceived facilitators of and barriers to uptaking VR systems among community-dwelling older adults.

Results

The screening and recruitment process for the experimental group started in May 2021, and the data collection process will be completed by September 2021. The timeline of the recruitment process for the control group is September 2021 to December 2021. We anticipate an estimated adherence rate of ≥80%. Challenges associated with VR technology and the complexity of remote assessments are expected.

Conclusions

This pilot study will provide important information on the feasibility, acceptability, and usability of a custom-made VR exergaming intervention to promote older adults’ well-being. Findings from this study will be useful to inform the methodology, design, study procedures, and assessment protocol for future large-scale trials of VR exergames with older adults as well as deepen the understanding of remote deployment and at-home use of VR for exercise in older adults.

Sleep Detection for Younger Adults, Healthy Older Adults, and Older Adults Living With Dementia Using Wrist Temperature and Actigraphy: Prototype Testing and Case Study Analysis

BACKGROUND

Sleep is essential for one's health and quality of life. Wearable technologies that use motion and temperature sensors have made it possible to self-monitor sleep. Although there is a growing body of research on sleep monitoring using wearable devices for healthy young-to-middle-aged adults, few studies have focused on older adults, including those living with dementia.

OBJECTIVE

This study aims to investigate the impact of age and dementia on sleep detection through movement and wrist temperature.

METHODS

A total of 10 younger adults, 10 healthy older adults, and 8 older adults living with dementia (OAWD) were recruited. Each participant wore a Mi Band 2 (accemetry-based sleep detection) and our custom-built wristband (actigraphy and wrist temperature) 24 hours a day for 2 weeks and was asked to keep a daily sleep journal. Sleep parameters detected by the Mi Band 2 were compared with sleep journals, and visual analysis of actigraphy and temperature data was performed.

RESULTS

The absolute differences in sleep onset and offset between the sleep journals and Mi Band 2 were 39 (SD 51) minutes and 31 (SD 52) minutes for younger adults, 49 (SD 58) minutes and 33 (SD 58) minutes for older adults, and 253 (SD 104) minutes and 161 (SD 94) minutes for OAWD. The Mi Band 2 was unable to accurately detect sleep in 3 healthy older adults and all OAWDs. The average sleep and wake temperature difference of OAWD (1.26 °C, SD 0.82 °C) was significantly lower than that of healthy older adults (2.04 °C, SD 0.70 °C) and healthy younger adults (2.48 °C, SD 0.88 °C). Actigraphy data showed that older adults had more movement during sleep compared with younger adults and that this trend appears to increase for those with dementia.

CONCLUSIONS

The Mi Band 2 did not accurately detect sleep in older adults who had greater levels of nighttime movement. As more nighttime movement appears to be a phenomenon that increases in prevalence with age and even more so with dementia, further research needs to be conducted with a larger sample size and greater diversity of commercially available wearable devices to explore these trends more conclusively. All participants, including older adults and OAWD, had a distinct sleep and wake wrist temperature contrast, which suggests that wrist temperature could be leveraged to create more robust and broadly applicable sleep detection algorithms.

Zero-Effort Ambient Heart Rate Monitoring Using Ballistocardiography Detected Through a Seat Cushion: Prototype Development and Preliminary Study

BACKGROUND

Cardiovascular diseases are a leading cause of death worldwide and result in significant economic costs to health care systems. The prevalence of cardiovascular conditions that require monitoring is expected to increase as the average age of the global population continues to rise. Although an accurate cardiac assessment can be performed at medical centers, frequent visits for assessment are not feasible for most people, especially those with limited mobility. Monitoring of vital signs at home is becoming an increasingly desirable, accessible, and practical alternative. As wearable devices are not the ideal solution for everyone, it is necessary to develop parallel and complementary approaches.

OBJECTIVE

This research aims to develop a zero-effort, unobtrusive, cost-effective, and portable option for home-based ambient heart rate monitoring.

METHODS

The prototype seat cushion uses load cells to acquire a user's ballistocardiogram (BCG). The analog signal from the load cells is amplified and filtered by a signal-conditioning circuit before being digitally recorded. A pilot study with 20 participants was conducted to analyze the prototype's ability to capture the BCG during five real-world tasks: sitting still, watching a video on a computer screen, reading, using a computer, and having a conversation. A novel algorithm based on the continuous wavelet transform was developed to extract the heart rate by detecting the largest amplitude values (J-peaks) in the BCG signal.

RESULTS

The pilot study data showed that the BCG signals from all five tasks had sufficiently large portions to extract heart rate. The continuous wavelet transform-based algorithm for J-peak detection demonstrated an overall accuracy of 91.4% compared with electrocardiography. Excluding three outliers that had significantly noisy BCG data, the algorithm achieved 94.6% accuracy, which was aligned with that of wearable devices.

CONCLUSIONS

This study suggests that BCG acquired through a seat cushion is a viable alternative to wearable technologies. The prototype seat cushion presented in this study is an example of a relatively accessible, affordable, portable, and unobtrusive zero-effort approach to achieve frequent home-based ambient heart rate monitoring.

The Time Is Now: A FASTER Approach to Generate Research Evidence for Technology-Based Interventions in the Field of Disability and Rehabilitation

Current approaches for generating high-quality research evidence for technology-based interventions in the field of disability and rehabilitation are inappropriate. Prevailing approaches often focus on randomized controlled trials as standard and apply clinical trial practices designed for pharmaceuticals; such approaches are unsuitable for technology-based interventions and are counterproductive to the goals of supporting people with disabilities and creating benefits for society. This communication is designed to: (1) advocate for the use of alternative approaches to generating evidence in the development and evaluation of technology-based interventions; (2) propose an alternative framework and guiding principles; and (3) stimulate action by multiple disciplines and sectors to discuss, adopt, and promote alternative approaches. Our Framework for Accelerated and Systematic Technology-based intervention development and Evaluation Research (FASTER) is informed by established innovation design processes, complex intervention development, evaluation, and implementation concepts as well as our collective experiences in technology-based interventions research and clinical rehabilitation practice. FASTER is intended to be meaningful, timely, and practical for researchers, technology developers, clinicians, and others who develop these interventions and seek evidence. We incorporate research methods and designs that better align with creating technology-based interventions and evidence for integration into practice. We propose future activities to improve the generation of research evidence, enable the selection of research methods and designs, and create standards for evidence evaluation to support rigor and applicability for technology-based interventions. With this communication we aim to improve and advance technology-based intervention integration from conception to use, thus responsibly accelerating innovation to have greater positive benefit for people and society.

Ethical Issues in Democratizing Digital Phenotypes and Machine Learning in the Next Generation of Digital Health Technologies

Digital phenotyping is the term given to the capturing and use of user log data from health and wellbeing technologies used in apps and cloud-based services. This paper explores ethical issues in making use of digital phenotype data in the arena of digital health interventions. Products and services based on digital wellbeing technologies typically include mobile device apps as well as browser-based apps to a lesser extent, and can include telephony-based services, text-based chatbots, and voice-activated chatbots. Many of these digital products and services are simultaneously available across many channels in order to maximize availability for users. Digital wellbeing technologies offer useful methods for real-time data capture of the interactions of users with the products and services. It is possible to design what data are recorded, how and where it may be stored, and, crucially, how it can be analyzed to reveal individual or collective usage patterns. The paper also examines digital phenotyping workflows, before enumerating the ethical concerns pertaining to different types of digital phenotype data, highlighting ethical considerations for collection, storage, and use of the data. A case study of a digital health app is used to illustrate the ethical issues. The case study explores the issues from a perspective of data prospecting and subsequent machine learning. The ethical use of machine learning and artificial intelligence on digital phenotype data and the broader issues in democratizing machine learning and artificial intelligence for digital phenotype data are then explored in detail.

Quantification of Resting-State Ballistocardiogram Difference Between Clinical and Non-Clinical Populations for Ambient Monitoring of Heart Failure

A ballistocardiogram (BCG) is a versatile bio-signal that enables ambient remote monitoring of heart failure (HF) patients in a home setting, achieved through embedded sensors in the surrounding environment. Numerous methods of analysis are available for extracting physiological information using the BCG; however, most have been developed based on non-clinical subjects. While the difference between clinical and non-clinical populations are expected, quantification of the difference may serve as a useful tool. In this work, the differences in resting-state BCGs of the two cohorts in a sitting posture were quantified. An instrumented chair was used to collect the BCG from 29 healthy adults and 26 NYHA HF class I and II patients while seated without any stress test for five minutes. Five 20-second epochs per subject were used to calculate the waveform fluctuation metric at rest (WFMR). The WFMR was obtained in two steps. The ensemble average of the segmented BCG heartbeats within an epoch were calculated first. Mean square errors (MSE) between different ensemble average pairs were then retrieved. The MSEs were averaged to produce the WFMR. The comparison showed that the clinical cohort had higher fluctuation than the non-clinical population and had at least 82.2% separation, suggesting that greater errors may result when existing algorithms were used. The WFMR acts as a bridge that may enable important features, including the addition of error margins in parameter estimation and ways to devise a calibration strategy when resting-state BCG is unstable.

Relational, Flexible, Everyday: Learning from Ethics in Dementia Research

Engaging in participatory research in HCI raises numerous ethical complexities such as consent, researcher relationships, and participant compensation. Doing HCI work in the area of dementia amplifies these issues, and researchers in this area are modelling ethical stances to ensure researcher-participant relationships focus on meaningful engagement and care. This paper presents an insight into the kinds of ethical foci required when doing design research with people living with dementia and their carers. We interviewed 22 HCI researchers with experience working in dementia care contexts. Our qualitative analysis outlines subsequent lessons-learned, such as recognition of the participants, self-care, research impact, and subjectivity in ethical review boards. Furthermore, we found the complexity of navigating both "everyday" and more formal, institutional ethics in dementia research has implications beyond the context of working with people with dementia and outline key considerations for ethical practices in socially orientated HCI research.

Participatory design and evaluation of virtual reality games to promote engagement in physical activity for people living with dementia

Background

Exercise is a key component of physical health and quality of life for people living with dementia; however, challenges related to dementia symptoms and aging can make it difficult for people living with dementia to engage in exercise. While immersive virtual reality is showing increasing promise for exercise and rehabilitation applications, there is a lack of research regarding its use with people living with dementia.

Methods

Through participatory design with exercise therapists, kinesiologists, and people living with dementia, we designed two virtual reality environments (a farm and a gym) that were implemented on head-mounted displays to support five different upper-body exercises. Virtual reality and comparable human-guided exercises were tested with six people living with dementia. Both qualitative and quantitative measures were used, including reaching distance, distance traversed, and speed as well as feelings of enjoyment, engagement, interest, easiness, comfort, and level of effort.

Results

Participants’ subjective responses, motion, and fitness parameters all demonstrated comparable results between virtual reality and human-guided exercises. Therapists’ feedback also supported virtual reality exercise as an appropriate and engaging method for people living with dementia.

Conclusions

Collaborating with experts and people living with dementia throughout the design process resulted in an intuitive and engaging design. The results suggest that head-mounted virtual reality has promising potential to support physical activity for people living with dementia.

Comparative Analysis of Gait Speed Estimation Using Wideband and Narrowband Radars, Thermal Camera, and Motion Tracking Suit Technologies

Research has shown that cognitive and physical functioning of older adults can be reflected in indicators such as walking speed. While changes in cognition, mobility, or health cause changes in gait speed, often gradual variations in walking speed go undetected until severe problems arise. Discrete clinical assessments during clinical consultations often fail to detect changes in day-to-day walking speeds and do not reflect walking speeds in everyday environments, where most of the mobility issues happen. In this paper, we compare four walking speed measurement technologies to a GAITRite mat (gold standard): (1) an ultra wideband radar (covering the band from 3.3 GHz to 10 GHz), (2) a narrow band 24-GHz radar (with a bandwidth of 250 MHz), (3) a perception Neuron Motion Tracking suit, and (4) a thermal camera. Data were collected in parallel using all sensors at the same time for 10 healthy adults for normal and slow walking paces. A comparison of the sensors indicates better performance at lower gait speeds, with offsets (when compared to GAITRite) between 0.1 and 20% for the ultra wideband radar, 1.9 and 17% for the narrowband radar, 0.1 and 38% for the thermal camera, and 1.7 and 38% for the suit. This paper supports the potential of unobtrusive radar-based sensors and thermal camera technologies for ambient autonomous gait speed monitoring for contextual, privacy-preserving monitoring of participants in the community.

Exploring interface design to support caregivers' needs and feelings of trust in online content

INTRODUCTION

Family caregivers of people living with dementia require a range of accurate, current, and reliable information throughout the care trajectory. Much of this information is available online, however it can be difficult for caregivers to identify and decide what content is relevant to them. Little is known about how online design cues impact family caregivers' decision to assess how trustworthy information is and whether to engage with it.

METHODS

Our exploratory research focused on the interface design of CARE-RATE, an online search tool intended to support more effective information searches for family caregivers seeking dementia care-related resources. Data from focus groups were coupled with design literature to inform the development of three mockups that were evaluated by seven dementia caregiver experts.

RESULTS

Participants preferred a search bar design because of its simplicity, familiarity, and functionality. Design elements that impact trust included logos from reputable organizations, transparency of content author, and ratings from other caregivers.

CONCLUSION

Feelings of trust regarding information, including the ability to ascertain trustworthiness, is a major aspect of caregivers' willingness to engage with online content. Transparency and familiarity appear to be key elements that impact caregivers' trust in online information, which agrees with current web design research.

Prototyping the Automated Food Imaging and Nutrient Intake Tracking System: Modified Participatory Iterative Design Sprint

BACKGROUND

A total of 45% of older adults living in long-term care (LTC) have some form of malnutrition. Several methods of tracking food and fluid intake exist, but they are limited in terms of their accuracy and ease of application. An easy-to-use, objective, accurate, and comprehensive food intake system designed with LTC in mind may provide additional insights regarding nutritional support systems and nutritional interventions.

OBJECTIVE

The aim of this study was to conduct a multistage participatory iterative design sprint of a Goldilocks quality horizontal prototype for the Automated Food Imaging and Nutrient Intake Tracking (AFINI-T) system. Specific design objectives included the following: (1) identify practice-relevant problems and solutions through user-centered participatory design, (2) mitigate feasibility-related barriers to uptake, and (3) employ user-centered technology development.

METHODS

A 6-stage iterative participatory design sprint was developed and executed. A total of 38 participants and advisors representing 15 distinct roles (eg, personal support worker, nurse, and dietitian) were engaged in the design sprint. Subjective workload (Raw Task Load Index), subjective usability scales, and a modified Ravden checklist were used to assess project advisors' perceptions of the AFINI-T system prototype compared with the current method of food and fluid intake charting.

RESULTS

The top priorities for this system were identified as the following: ease of use, high accuracy, system reliability, ease of maintenance, and requirement of integrating with the current PointClickCare system. Data from project advisors informed design decisions leading to a Goldilocks quality horizontal prototype of the AFINI-T system. Compared with the current food and fluid intake charting system, AFINI-T was perceived to have the following: less time demands (t_10.8=4.89; P<.001), less effort (t_13.5=5.55; P<.001), and less frustration (t_13.0=3.80; P=.002). Usability ratings of the AFINI-T prototype were high, with a subjective usability score mean of 89.2 and the highest ratings on a modified Ravden usability checklist of "very satisfactory" for 7 out of 8 sections.

CONCLUSIONS

The AFINI-T concept system appears to have good practice relevance as a tool for an intelligent food and fluid intake tracking system in LTC. The AFINI-T concept system may provide improvement over the current system, and advisors are keen to try the AFINI-T system. This research gives tangible examples of how the sprint method can be adapted and applied to the development of novel needs-based application-driven technology.

Age-Related Changes in Vibro-Tactile EEG Response and Its Implications in BCI Applications: A Comparison Between Older and Younger Populations

The rapid increase in the number of older adults around the world is accelerating research in applications to support age-related conditions, such as brain-computer interface (BCI) applications for post-stroke neurorehabilitation. The signal processing algorithms for electroencephalogram (EEG) and other physiological signals that are currently used in BCI have been developed on data from much younger populations. It is unclear how age-related changes may affect the EEG signal and therefore the use of BCI by older adults. This research investigated the EEG response to vibro-tactile stimulation from 11 younger (21.7±2.76 years old) and 11 older (72.0±8.07 years old) subjects. The results showed that: 1) the spatial patterns of cortical activation in older subjects were significantly different from those of younger subjects, with markedly reduced lateralization; 2) there is a general power reduction of the EEG measured from older subjects. The average left vs. right BCI performance accuracy of older subjects was 66.4±5.70%, 15.9% lower than that of the younger subjects (82.3±12.4%) and statistically significantly different (t(10)= -3.57, p= 0.005). Future research should further investigate age-differences that may exist in electrophysiology and take these into consideration when developing applications that target the older population.

Unobtrusive Detection of Simulated Orthostatic Hypotension and Supine Hypertension Using Ballistocardiogram and Electrocardiogram of Healthy Adults

Effective management of neurogenic orthostatic hypotension and supine hypertension (SH-OH) due autonomic failure requires a frequent and timely adjustment of medication throughout the day to maintain the blood pressure (BP) within the normal range, i.e., an accurate depiction of BP is a key prerequisite of effective management. One of the emerging technologies that provide one’s circadian and long-term physiological status with increased usability is unobtrusive zero-effort monitoring. In this paper, a zero-effort device, a floor tile, was used to develop an unobtrusive BP monitoring technique. Namely, RJ-interval, the time between the J-peak of a ballistocardiogram and the R-peak of an electrocardiogram, was used to develop a classifier that can detect changes in systolic BP (SBP) induced by the Valsalva maneuver on healthy adults (i.e., a simulated SH-OH). A t-test was used to show statistical differences between the mean RJ-intervals of decreased SBP, baseline, and increased SBP. Following the t-test, a classifier that detected a change in SBP was developed based on a naïve Bayes classifier (NBC). The t-test showed a clear statistical difference between the mean RJ-intervals of the increased SBP, baseline, and decreased SBP. The NBC-based classifier was able to detect increased SBP with 89.3% true positive rate (TPR), 100% true negative rate (TNR), and 94% accuracy and detect decreased SBP with 92.3% TPR, 100% TNR, and 95% accuracy. The analysis showed strong potential in using the developed classifier to assist monitoring of people with SH-OH; the algorithm may be used clinically to detect a long-term trend of symptoms of SH-OH.

Technology for fostering intergenerational connectivity: scoping review protocol

BACKGROUND

The simultaneous increase in geographically dispersed families and general decrease in engagement in local communities is resulting in fewer opportunities for youth and older adults interact in meaningful ways. Technology is becoming increasingly pervasive and flexible and providing new opportunities to foster intergenerational connection that can be implemented and evaluated across a multitude of populations and contexts. What research has been done in this area is spread across disciplines and what aspects of technologies could make them more effective is not well understood.

METHOD

The scoping review will be completed in five stages: (1) identifying the research question, (2) identifying relevant studies, (3) selecting studies, (4) charting the data, and (5) collating, summarizing, and reporting the results. Comprehensive descriptive data from each study will be presented along with an analysis of similarities and differences in research from different disciplines.

DISCUSSION

This scoping review focuses on a search of the literature to gain an understanding of what technologies have been used specifically for fostering intergenerational connectivity and to establish what future directions for research could be. To the authors' knowledge, it is the first scoping review of its kind.

Evaluating the effectiveness of different external cues on non-invasive brain-computer interfaces

Although BCI technology has vastly improved in the last few years, very little research has been done into how different types of cues may affect the resulting signal. We have conducted preliminary work to examine the effects of using auditory versus visual cues on MRCP signal detection. While our sample size was small (n=5), the data for auditory and visual cues were not statistically different for young, healthy participants, suggesting that they are comparable for the parameters analyzed. Our results indicated that audio and visual cues likely produce similar MRCP signals, which is useful information for designing non-invasive BCIs. Future work includes expanding the sample size and conducting work with special needs populations, such as children with Autism Spectrum Disorder (ASD), who are known to have strong preferences for different interfaces.

Non-invasive brain stimulation interventions for management of chronic central neuropathic pain: a scoping review protocol

INTRODUCTION

Pain can affect people regardless of age, gender or ethnicity. Chronic central neuropathic pain (CCNP) is a debilitating condition that affects populations such as stroke survivors, amputees, spinal cord injury patients and patients with multiple sclerosis, with prevalence rates between 30% and 80%. This condition can be caused by a lesion or disease affecting the somatosensory system. CCNP is notoriously drug resistant, and few effective CCNP treatment or management strategies exist. The emergence of non-invasive brain stimulation and neuromodulation techniques provide novel avenues for managing chronic central neuropathic pain. This scoping review aims to systematically identify the methods and effectiveness of non-invasive brain stimulation techniques for treating and managing chronic central neuropathic pain.

METHODS AND ANALYSIS

The following databases will be searched systematically: PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Institute of Electric and Electronic Engineers (IEEE), Association of Computing Machinary (ACM) and Scopus. Additional literature will be identified by searching the reference lists of identified studies. Studies will include reviews and original research in both published and grey literatures. Two reviewers will independently screen identified studies for final inclusion. A quantitative analysis on the intervention type, application and efficacy will be synthesised along with a qualitative analysis to describe the effectiveness of each intervention.

ETHICS AND DISSEMINATION

No primary data will be collected and hence formal ethics review is not required. The results of the scoping review will be presented at relevant national and international conferences, published in a peer-reviewed journal and provided to the stakeholders with plain language to be posted on their websites. This scoping review will provide a foundation to guide the development of future primary research on non-invasive brain stimulation and CCNP.

Principles for fostering the transdisciplinary development of assistive technologies

Developing useful and usable assistive technologies often presents complex (or "wicked") challenges that require input from multiple disciplines and sectors. Transdisciplinary collaboration can enable holistic understanding of challenges that may lead to innovative, impactful and transformative solutions. This paper presents generalised principles that are intended to foster transdisciplinary assistive technology development. The paper introduces the area of assistive technology design before discussing general aspects of transdisciplinary collaboration followed by an overview of relevant concepts, including approaches, methodologies and frameworks for conducting and evaluating transdisciplinary working and assistive technology design. The principles for transdisciplinary development of assistive technologies are presented and applied post hoc to the COACH project, an ambient-assisted living technology for guiding completion of activities of daily living by older adults with dementia as an illustrative example. Future work includes the refinement and validation of these principles through their application to real-world transdisciplinary assistive technology projects. Implications for rehabilitation Transdisciplinarity encourages a focus on real world 'wicked' problems. A transdisciplinary approach involves transcending disciplinary boundaries and collaborating with interprofessional and community partners (including the technology's intended users) on a shared problem. Transdisciplinarity fosters new ways of thinking about and doing research, development, and implementation, expanding the scope, applicability, and commercial viability of assistive technologies.

Interdisciplinary development of manual and automated product usability assessments for older adults with dementia: lessons learned

The changes in cognitive abilities that accompany dementia can make it difficult to use everyday products that are required to complete activities of daily living. Products that are inherently more usable for people with dementia could facilitate independent activity completion, thus reducing the need for caregiver assistance. The objectives of this research were to: (1) gain an understanding of how water tap design impacted tap usability and (2) create an automated computerized tool that could assess tap usability. 27 older adults, who ranged from cognitively intact to advanced dementia, completed 1309 trials on five tap designs. Data were manually analyzed to investigate tap usability as well as used to develop an automated usability analysis tool. Researchers collaborated to modify existing techniques and to create novel ones to accomplish both goals. This paper presents lessons learned through the course of this research, which could be applicable in the development of other usability studies, automated vision-based assessments and the development of assistive technologies for cognitively impaired older adults. Collaborative interdisciplinary teamwork, which included older adult with dementia participants, was key to enabling innovative advances that achieved the projects' research goals. Implications for Rehabilitation Products that are implicitly familiar and usable by older adults could foster independent activity completion, potentially reducing reliance on a caregiver. The computer-based automated tool can significantly reduce the time and effort required to perform product usability analysis, making this type of analysis more feasible. Interdisciplinary collaboration can result in a more holistic understanding of assistive technology research challenges and enable innovative solutions.

Examining the impact of familiarity on faucet usability for older adults with dementia

BACKGROUND

Changes in cognition caused by dementia can significantly alter how a person perceives familiarity, impacting the recognition and usability of everyday products. A person who is unable to use products cannot autonomously complete associated activities, resulting in increased dependence on a caregiver and potential move to assisted living facilities. The research presented in this paper hypothesised that products that are more familiar will result in better usability for older adults with dementia. Better product usability could, in turn, potentially support independence and autonomy.

METHODS

This research investigated the impact of familiarity on the use of five faucet designs during 1309 handwashing trials by 27 older adults, who ranged from cognitively intact to the advanced (severe) stages of dementia. Human factors methods were used to collect empirical and self-reported data to gauge faucets' usability. Participants' data were grouped according to cognition (i.e., no/mild, moderate, or severe dementia). Logistic regression, ranking by odds, and Wald tests of odds ratios were used to compare performance of the three groups on the different faucets. Qualitative data were used in the interpretation of quantitative results.

RESULTS

Results indicated that more familiar faucets correlated with lower levels of assistance from a caregiver, fewer operational errors, and greater levels of operator satisfaction. Aspects such as the ability to control water temperature and flow as well as pleasing aesthetics appeared to positively impact participants' acceptance of a faucet. The dual lever design achieved the best overall usability.

CONCLUSIONS

While work must be done to expand these findings to other products and tasks, this research provides evidence that familiarity plays a substantial role in product usability for older adults that appears to become more influential as dementia progresses. The methods used in this research could be adapted to analyse usability for other products by older adults with dementia.

The future of intelligent assistive technologies for cognition: devices under development to support independent living and aging-with-choice

A person's ability to be independent is dependent on his or her overall health, mobility, and ability to complete activities of daily living. Intelligent assistive technologies (IATs) are devices that incorporate context into their decision-making process, which enables them to provide customised and dynamic assistance in an appropriate manner. IATs have tremendous potential to support people with cognitive impairments as they can be used to support many facets of well-being; from augmenting memory and decision making tasks to providing autonomous and early detection of possible changes in health. This paper presents IATs that are currently in development in the research community to support tasks that can be impacted by compromised cognition. While they are not yet ready for the general public, these devices showcase the capabilities of technologies one can expect to see in the consumer marketplace in the near future.

The development of an upper limb stroke rehabilitation robot: identification of clinical practices and design requirements through a survey of therapists

PURPOSE. Timely and adequate rehabilitation after a stroke is crucial to maximising recovery. A way of increasing treatment access could be through robots, which would aid therapists in providing post-stroke rehabilitation. This research sought to discover the needs and preferences of therapists with respect to a robot that focuses on upper limb rehabilitation. Understanding requirements for devices could help to increase integration into clinical practice. METHODS. An international online survey was distributed through professional organisations and e-mail list services to therapists. The survey contained 85 items covering topics such as therapist background and treatment approach, rehabilitation aims and robotic rehabilitation device attributes. RESULTS. Data were analysed for 233 respondents, most of whom were physiotherapists and occupational therapists from Australia, Canada and USA. Top attributes included: facilitating a variety of arm movements, being usable while seated, giving biofeedback to clients, having virtual activities specific to daily living, being useful in-home and having resistance adjustable to client needs. In addition, the device should cost under 6000 USD. CONCLUSIONS. Findings from this survey provide guidance for technology developers regarding therapists' specifications for a robotic device for upper limb rehabilitation. In addition, findings offer a better understanding of how acceptance of such devices may be facilitated.
