Evaluating the use of interactive virtual reality technology with older adults living in residential aged care

Introducing virtual reality to older adults: A qualitative analysis of a co-design innovation with care staff

Previous studies of Virtual Reality (VR) in aged care settings have demonstrated that the benefits can be multiple, including improved social connection and engagement and reduced social isolation in later life. However, there remains a lack of widespread uptake of VR in aged care facilities. This prompts an important question: Given the potential benefits, why is there such poor engagement in VR by aged care facilities? The aim of this qualitative study is to investigate the experience of introducing VR into an aged care facility. Our innovative approach supported care staff to introduce VR into aged care facilities. Fieldwork diaries and focus group discussions were used to document experiences of introducing VR, including the obstacles, challenges and benefits and the adaptations to aged care environments that were required to accommodate new VR activities. Thematic analysis of the data revealed that VR can be an important medium to support the wellbeing of older residents. However, our findings also indicate that there are significant challenges associated with introducing VR, including substantial costs in time, money and institutional resources and attention. This study concludes that, to be successful, VR requires substantive care and relational resources from both staff and residents that are only visible when paying attention to the contextual adjustments required to introduce the technology to a new setting. This suggests that other research on gerontechnologies would likely also benefit from further attention to the role of the broader social context - including care and relational resources - in ensuring their successful design and implementation.

Mapping of technological strategies for reducing social isolation in homebound older adults: A scoping review

BACKGROUND

Homebound older adults (HOAs) are particularly vulnerable to social isolation and loneliness, which engender a poorer physical and mental health, and greater cognitive decline. The purpose of this review is to map the literature to identify potential technological strategies that reduce social isolation in HOAs, and to understand facilitators and barriers for adoption and implementation.

METHODS

Six databases including PubMed (MEDLINE), Google Scholar, Cochrane Database, EBSCOHost, National Library ProQuest, Web of Science, and the Journal of Medical Internet Research were searched for relevant articles. Peer-reviewed literature published in English from Jan 2014 to Feb 2024 that employed technological strategies applicable to HOAs and assessed social isolation or connectedness as an outcome measure were included.

RESULTS

107 studies were reviewed and classified into different technological categories based on their functions and features. A social technology framework encompassing delivery, hardware, software, content, training, and support was conceptualized with core characteristics identified from the reviewed technological strategies. Cost and complexity of technology, and resource commitment were identified as barriers while user-friendliness, content curation and a supportive ecosystem may facilitate the adoption of a technological strategy to address social isolation in HOAs.

CONCLUSION

There is a need for early and concerted effort to identify HOAs, provide technology training, and empower them to tap on the digital world to complement and/or supplement social interactions. Development of cost-effective and rapid-to-implement technology is vital for HOAs who are at highest risk to social isolation.

Virtual reality-based reminiscence therapy for older adults to improve psychological well-being and cognition: A systematic review

BACKGROUND

Virtual reality-reminiscence therapy (VR-RT) has increasingly been applied to older adults to improve psychological well-being and cognition.

OBJECTIVE

This review aims to identify (1) the design characteristics of conducting a VR-RT and (2) the effects of VR-RT on the user experience, cognitive outcomes and psychological well-being.

DESIGN

Systematic review.

METHODS

Eligible studies were sourced across nine electronic databases, trial registries, grey literature and hand-searching of the reference list. A narrative synthesis was conducted. Twenty-two studies were included, and most were appraised as high quality. Most of the VR-RTs were highly immersive and personalised, with participants having the autonomy of control. VR-RT has the potential to improve anxiety and depression, and cognitive outcomes for older adults. Overall, VR-RT was reported to be an enjoyable experience for older adults.

CONCLUSIONS

VR-RT is a promising innovation that can improve older adults' psychological well-being and cognition without significant side effects, including cybersickness and with the potential for scalability across various settings. More randomised controlled studies are needed to evaluate the effectiveness of VR-RT and its features and treatment dosage. These studies could also examine the effectiveness of VR-RT as an intervention to promote independence in activities of daily living and physical rehabilitation.

RELEVANCE TO CLINICAL PRACTICE

VR-RT is a promising intervention for older adults in community settings to enhance psychological well-being and cognition. VR's versatility enables personalised experiences within dynamic virtual environments, possibly enhancing engagement and therapeutic outcomes.

Community-Based Virtual Reality Interventions in Older Adults with Dementia and/or Cognitive Impairment: A Systematic Review

INTRODUCTION

Virtual reality devices have been widely used for the rehabilitation among older people with cognitive impairments. They enable the user to navigate in three-dimensional environments, which are constructed by a computer. Recent studies have been focused on the cognitive benefits of virtual reality for people with cognitive deficits. The current study aimed to investigate the overall impact of community-based virtual reality interventions in older adults with dementia and/or cognitive impairment.

METHODS

A systematic review of the literature was conducted according to the PRISMA guidelines. Google Scholar, PubMed, Science Direct and Scopus databases were searched for the years 2010-2022.

RESULTS

Of the 245 articles 20 met the inclusion criteria. The results of the current systematic review indicated that virtual reality improved older adults' cognitive and motor skills and increased their positive emotions while minimizing less positive ones. However, there is insufficient data of its impact on their overall quality of life.

CONCLUSION

There is a need to implement and evaluate interventions that examine its impact not only on cognitive functioning, but also on other aspects of older people with cognitive deficits.

Exploring older adult needs and preferences for technology-assisted group music-making. A qualitative analysis of data collected during the participatory user-centred design process

PURPOSE

Engagement with arts, recreation and leisure is highly valued by older adults, with positive links to their continued wellbeing. Despite an availability of new music technology, these devices are rarely designed with older adults in mind. This project explores the needs and preferences of older adults in residential care as they interact with digital music interfaces in a group music-making context.

MATERIALS AND METHODS

Twenty participants at an Australian residential aged-care facility were involved in a user-centred design process (20 sessions across six months) to develop digital music interfaces suitable for group music-making. Participants' verbal comments were audio-recorded and transcribed, supported by further written observation notes made by the activity facilitators.

RESULTS

A hybrid inductive and deductive approach to thematic analysis revealed three main themes: individual music-making, ensemble music-making and social engagement. Our results suggest that when interfaces are designed with older adults in mind, technology-assisted group music-making can facilitate bringing together residents with different experiences and abilities.

CONCLUSIONS

These findings suggest implications for rehabilitation in developing a range of musical devices for older adults to account for required flexibility, whilst maintaining an appropriate and satisfyingly "rich" musical outcome.

Can 'What Is Known' about Social Isolation and Loneliness Interventions Sufficiently Inform the Clinical Practice of Health Care and Social Service Professionals Who Work with Older Adults? Exploring Knowledge-to-Practice Gaps

Establishing intervention effectiveness is an important component of a broader knowledge translation (KT) process. However, mobilizing the implementation of these interventions into practice is perhaps the most important aspect of the KT cycle. The purpose of the current study was to conduct an umbrella review to (a) identify promising interventions for SI&L in older adults, (b) interpret (translate) the findings to inform clinical knowledge and practice interventions in different settings and contexts, and (c) highlight research gaps that may hinder the uptake of these interventions in practice. The broader purpose of this study was to inform evidence-based clinical practice guidelines on SI&L for HCSSPs. In line with other reviews, our study noted variations in methods and intervention designs that prohibit definitive statements about intervention effectiveness. Perhaps, the most significant contribution of the current review was in identifying knowledge-to-practice gaps that inhibit the implementation of interventions into practice-based realities.

Potential of virtual reality to meaningfully engage adults living with dementia in care settings: A scoping review

INTRODUCTION

Older adults living with dementia in residential aged care homes receive physical care but may have limited access to meaningful engagement. Due to its multimodal and versatile nature, virtual reality (VR) is speculated to be an effective means of meaningfully engaging residents individually and/or in groups. However, there is little evidence regarding its efficacy as a means of meaningfully engaging older adults living with dementia. The objective of this scoping review is to identify and synthesise published research investigating the use of VR technology in promoting the meaningful engagement of older adults living with dementia in residential aged care facilities.

METHODS

A scoping review following Arksey and O'Malley's (2005) established process was conducted and included identifying and selecting relevant studies from seven databases (i.e., AgeLine, CINAHL, Medline, Cochrane, Embase, PsycINFO and Scopus), data charting, and collating, summarising and reporting findings. Two independent reviewers used Covidence and Excel to support data extraction and analysis.

RESULTS

The 20 eligible studies revealed discrepancies in the classification of VR and strengths, weaknesses, opportunities and threats associated with its implementation. Findings indicate that the most influential factor in eliciting meaningful engagement is when VR use facilitates interpersonal interactions and opportunities for human connection.

CONCLUSION

Although VR seems to be a promising medium in engaging older adults living with dementia, the efficacy of implementing VR technology within care facilities should be considered alongside potential environmental enablers and barriers. The apparent strength of implementing VR as a means of encouraging restoration, pleasure and productivity in older adults living with dementia lies in the fact that it creates opportunities for meaningful engagement on social and occupational levels.

Transforming aged care with virtual reality: How organisational culture impacts technology adoption and sustained uptake

OBJECTIVES

Virtual reality (VR) is not a common leisure activity in aged care, despite pilot studies demonstrating its value as a tool to combat inactivity and loneliness. This study investigated the organisational enablers and barriers to sustained uptake of VR among aged care staff and organisations, who may lack familiarity or confidence with the technology.

METHODS

Creative methods were adopted to co-design and develop a VR implementation toolkit tailored specifically for aged care staff. Three aged care homes in South-East Queensland participated, with 15 residents and seven staff engaging in up to four VR sessions facilitated by the research team. Participant observation of the VR sessions was complemented by interviews with aged care staff and residents.

RESULTS

Guided by Normalisation Process Theory, a reflexive thematic analysis identified four key themes: (1) Positively Appreciating the VR Experience, (2) Staff VR Champions and the Importance of Personal Use and Experimentation with VR, (3) Management Support and (4) Technical Challenges.

CONCLUSIONS

Our results indicate benefits and challenges of VR use in aged care, offering valuable insights into the factors that can lead to the long-term success of VR-based leisure activities for aged care. Providing time and resources for a VR champion to experiment and learn about the technology is critical. The development of an online implementation toolkit, based on our learning from this project, also provides aged care stakeholders with the evidence-based resources needed to ensure the successful implementation of VR-based leisure programs.

Forest therapy using virtual reality in the older population: a systematic review

Introduction

As life expectancy increases, more attention needs to be paid to their mental and physical condition. Many older patients are also bedridden, which makes some treatments, like in vivo exposure to natural environments, more difficult to be applied. This study aimed to systematically review articles that include interventions combining virtual reality and forest environment, targeting a sample of older people.

Methods

Based on PRISMA guidelines, we conducted a literature search in three databases (EBSCO, PubMed, and Scopus), plus gray literature (OpenGrey). We considered only studies that used forest settings via virtual reality and included a sample with age ≥ 65.

Results

After the screening and eligibility stages, 7 articles have been included.

Discussion

The study underlines the need to implement research in this direction to standardize effective procedures that can be used to improve the mental and physical health of the older people and caregivers, while also reducing social costs.

Immersive virtual reality in the promotion of health and well-being for people in residential aged care without cognitive impairment: A scoping review

Objective

Sustaining the health and well-being of older people living in residential aged care (RAC) requires new means of providing safe and stimulating recreational and therapeutic programs such as using virtual reality (VR). The aim of the scoping review was to investigate the utility of immersive VR interventions using head-mounted display technology to promote the health and well-being of people without cognitive impairment living in RAC.

Method

The following databases were searched from inception until January 2024: PubMed, PsycINFO, Scopus, Cochrane and CINAHL. The eligibility criteria were quantitative, qualitative or mixed methods studies published in English, conducted in RAC, using VR with head-mounted display with people without cognitive impairment.

Results

Of the 274 articles identified, 9 articles with a total of 310 residents and 50 staff met the inclusion criteria. Seven factors to either impede or enable the use of VR with head-mounted displays in RAC were: residents' agency; the nature of the VR experience; the content of the experience; the ease of use and comfort of the technology; the role of RAC staff; and the role of residents' family members.

Conclusion

Immersive VR has potential as a tool to promote the health and well-being of people without cognitive impairment living in RAC. Small sample sizes, variations in study design, and selection bias mean that generalisability of the results is limited. Further research is recommended to inform the design and implementation of immersive VR programs tailored specifically for this population.

Effect of Immersive Virtual Reality Reminiscence versus Traditional Reminiscence Therapy on Cognitive Function and Psychological Well-being among Older Adults in Assisted Living Facilities: A randomized controlled trial

BACKGROUND

Virtual reality (VR) reminiscence is an innovative strategy that integrates technology into the care of older adults. Limited research was conducted to compare the role of VR reminiscence and traditional RT in improving older adults' cognitive and psychological well-being.

AIM

Investigate the effect of virtual reality reminiscence versus traditional reminiscence therapy on cognitive function and psychological well-being among older adults in assisted living facilities.

METHODS

A randomized controlled trial research design was followed. Sixty older adults were recruited and randomly assigned to three equal groups (20 older adults for each group).

RESULTS

Post interventions, a significant increase in the mean scores of cognitive function and psychological well-being was evident among the VR and RT groups with statistically significant differences (P <0.05) compared with pre-intervention and the control group.

CONCLUSION

Application of VR reminiscence or traditional RT is efficacious in improving cognitive function and psychological well-being among institutionalized older adults.

From 65 to 103, Older Adults Experience Virtual Reality Differently Depending on Their Age: Evidence from a Large-Scale Field Study in Nursing Homes and Assisted Living Facilities

There is growing interest in applications of virtual reality (VR) to improve the lives of older adults, but the limited research on older adults and VR largely treats older adults as a monolith, ignoring the substantial differences across 65 to 100+ year olds that may affect their experience of VR. There are also few existing studies examining the experiences and challenges facing those who facilitate VR for older adults (e.g., caregiving staff). We address these limitations through two studies. In study 1, we explore variation within older adults' experiences with VR through a field study of VR use among a large (N = 245) and age-diverse (Mage = 83.6 years, SDage = 7.9, range = 65-103 years) sample of nursing home and assisted living facility residents across 10 U.S. states. Age was negatively associated with the extent to which older adults enjoyed VR experiences. However, the negative relationship between age and older adults' attitudes toward VR was significantly less negative than the relationship between age and their attitudes toward other technologies (cell phones and voice assistants). In study 2, we surveyed caregiving staff (N = 39) who facilitated the VR experiences for older adult residents and found that the caregiving staff generally enjoyed the activity relative to other activities and felt it to be beneficial to their relationship with residents.

Social virtual reality helps to reduce feelings of loneliness and social anxiety during the Covid-19 pandemic

Evidence shows that the Covid-19 pandemic caused increased loneliness, anxiety and greater social isolation due to social distancing policies. Virtual reality (VR) provides users with an easy way to become engaged in social activities without leaving the house. This study focused on adults, who were socialising in Altspace VR, a social VR platform, during the Covid-19 pandemic and it explored whether social VR could alleviate feelings of loneliness and social anxiety. A mixed-methods research design was applied. Participants (n = 74), aged 18-75, completed a questionnaire inside the social VR platform to measure levels of loneliness (UCLA 20-item scale) and social anxiety (17-item SPIN scale) in the social VR platform (online condition) and real world (offline condition). Subsequently, a focus group (n = 9) was conducted to gather insights into how and why participants were using the social VR platform. Findings from the questionnaire revealed significantly lower levels of loneliness and social anxiety when in the social VR platform. Lower levels of loneliness and social anxiety were also associated with participants who socialised with a regular group of friends. In addition, findings from the focus group suggested that being part of an online group facilitates stronger feelings of belonging. Social VR can be used as a valuable intervention to reduce feelings of loneliness and social anxiety. Future studies should continue to establish whether social VR can help to encourage group formation and provide people with enhanced social opportunities beyond the COVID-19 pandemic.

Assessing Virtual Reality Spaces for Elders Using Image-Based Sentiment Analysis and Stress Level Detection

Seniors, in order to be able to fight loneliness, need to communicate with other people and be engaged in activities to keep their minds active to increase their social capital. There is an intensified interest in the development of social virtual reality environments, either by commerce or by academia, to address the problem of social isolation of older people. Due to the vulnerability of the social group involved in this field of research, the need for the application of evaluation methods regarding the proposed VR environments becomes even more important. The range of techniques that can be exploited in this field is constantly expanding, with visual sentiment analysis being a characteristic example. In this study, we introduce the use of image-based sentiment analysis and behavioural analysis as a technique to assess a social VR space for elders and present some promising preliminary results.

Exploring the content of the STAND-VR intervention: A qualitative interview study

Prolonged sedentary behaviour has been identified as a potential independent contributor to a number of chronic conditions as well as mortality. The integration of digital technology into health behaviour change interventions has been shown to contribute to increases in physical activity levels, reductions in time spent sedentary, reductions in systolic blood pressure and improvements physical functioning. Recent evidence suggests that older adults could be motivated to adopt a technology such as immersive virtual reality (IVR) due to the added agency it can potentially afford them in their lives through physical and social activities offered in IVR. To date, little research has attempted to integrate health behaviour change content into an immersive virtual environment. This study aimed to qualitatively explore older adults' perspectives on the content of a novel intervention, STAND-VR, and how it could be integrated into an immersive virtual environment. This study was reported using the COREQ guidelines. Twelve participants aged between 60 and 91 years took part. Semi-structured interviews were conducted and analysed. Reflexive thematic analysis was the chosen method of analysis. Three themes were developed, "Immersive Virtual Reality: The Cover versus the Contents", "Ironing Out the (Behavioural) Details" and, "When Two Worlds Collide". These themes offer insights into how retired and non-working adults perceived IVR before and after use, how they would like to learn how to use IVR, the content and people they would like to interact with and finally, their beliefs about their sedentary activity and using IVR. These findings will contribute to future work which aims to design IVR experiences that are more accessible to retired and non-working adults, offering greater agency to take part in activities that reduce sedentary behaviour and improve associated health outcomes and, importantly, offer further opportunity to take part in activities they can ascribe greater meaning to.

Facilitators and Barriers to Using Virtual Reality and its Impact on Social Engagement in Aged Care Settings: A Scoping Review

Aim: This scoping review aims to identify the facilitators and barriers to the implementation of VR technology in the aged-care setting. Background: Virtual reality (VR) offers the potential to reduce social isolation and loneliness through increased social engagement in aged-care settings. Methods and Analysis: This scoping review followed the Joanna Briggs Institute scoping review methodology and took place between March and August 2022. The review included a three-step search strategy: (1) identifying keywords from CINHAL, Embase, Medline, PsycInfo, Scopus, and Web of Science (2) conducting a second search using all identified keywords and index terms across selected databases; and (3) searching the reference lists of all included articles and reports for additional studies. Results: The final review included 22 articles. The analysis identified factors affecting the VR technology implementation in aged care settings to reduce isolation and loneliness: (a) key facilitators are local champions and staff training. (b) barriers include technological adaptability, video quality, and organizational culture. Conclusion: Existing evidence points to VR as a promising intervention to decrease loneliness and feelings of isolation and improve social engagement in older people living in aged-care settings.

A modified mental state assessment tool for impact analysis of virtual reality-based therapeutic interventions in patients with cognitive impairment

Objectives

This work has developed a modified mental state assessment tool for impact analysis of therapeutic interventions for patients with cognitive impairment. This work includes a pilot study to validate the proposed tool and assess the impact of virtual reality-based interventions on patient well-being, which includes assessment of cognitive ability and mood.

Methods

The suggested tool's robustness and reliability are assessed in care home facilities with elderly residents over the age of 55. Because of the repetitive nature of the pilot study, test-retest strategy for Cronbach's alpha coefficient is employed to validate the internal consistency of the proposed tool over time. Qualitative and quantitative analyses are performed on the collected data to draw inferences on the impact of virtual reality-based interventions on patients with cognitive impairments.

Results

The Cronbach's alpha coefficient value shows that the proposed tool's resilience is comparable to that of its pre-intervention counterparts. The Cronbach's alpha coefficient values are determined for Pre-virtual reality and Post-virtual reality interventions, which include 116 virtual reality sessions for 52-participant, and three cohorts of virtual reality sessions for 21 participants. These values for a majority of the interventions remained within the acceptable range of 0.6-0.8.

Conclusions

The proposed modified mental state assessment tool is observed to be a reliable tool for investigating the impact of virtual reality-based interventions on patients with cognitive impairments. One of the notable significance of the proposed tool is that this allows for resource allocation for such interventions to be tailored to the needs of the patient, leading to greater therapeutic efficacy and resource efficiency.

Application of Immersive Virtual-Reality-Based Puzzle Games in Elderly Patients with Post-Stroke Cognitive Impairment: A Pilot Study

Background: The society is aging in China, and the cognitive level of elderly post-stroke patients gradually declines. Face-to-face cognitive functional training is no longer sufficient. Immersive virtual reality (IVR) is a promising rehabilitation training device. In this study, we developed an IVR-based puzzle game to explore its effectiveness, feasibility, and safety in elderly stroke patients with cognitive dysfunction. Methods: A total of 30 patients with mild post-stroke cognitive impairment after stroke were randomly assigned to a control or IVR group. Patients in both groups received routine rehabilitation therapy. Patients in the control group received traditional cognitive training, and those in the IVR group received IVR-based puzzle game therapy. Before and after treatment, Montreal cognitive assessment (MOCA), trail-making test-A (TMT-A), digit symbol substitution test (DSST), digital span test (DST), verbal fluency test (VFT), and modified Barthel index (MBI) were evaluated in both groups. In addition, the IVR group was administered a self-report questionnaire to obtain feedback on user experience. Results: There was no significant difference in the baseline data between the two groups. After six weeks of treatment, the cognitive assessment scores were improved in both groups. Moreover, the IVR group showed more improvements than the control group in the DSST (Z = 2.203, p = 0.028 < 0.05, η2 = 0.16); MOCA (T = 1.186, p = 0.246 > 0.05, d = 0.44), TMT-A (T = 1.791, p = 0.084 > 0.05, d = 0.65), MBI (T = 0.783, p = 0.44 > 0.05, d = 0.28), FDST (Z = 0.78, p = 0.435 > 0.05, η2 = 0.02), BDST (Z = 0.347, p = 0.728 > 0.05, η2 = 0.004), and VFT(Z = 1.087, p = 0.277 > 0.05, η2 = 0.039) did not significantly improve. The significant difference in DSST represents an improvement in executive function and visual−spatial cognitive characteristics. The other assessment scores did not show such features. Therefore, we did not observe significant differences through this measure. According to the results of the self-report questionnaire, most of the patients were satisfied with the equipment stability and training content. Several individuals reported mild adverse reactions. Conclusions: This pilot study suggests that IVR-based puzzle games are a promising approach to improve post-stroke cognitive function, especially executive cognitive function, and visual−spatial attention in older adults.

Key Stakeholders' Experiences and Perceptions of Virtual Reality for Older Adults Living With Dementia: Systematic Review and Thematic Synthesis

BACKGROUND

Technology is increasingly being used and evolving in the dementia care landscape. One such technology that has gained traction over the last decade is virtual reality (VR). VR is being applied in many areas of dementia care, including cognitive assessment and training, reminiscence therapy, music therapy, and other recreational VR applications. Despite the plethora of applications, they are often not shaped by the experiences and perceptions of older adults living with dementia. Currently, there is no qualitative evidence synthesis (QES) to explore this area. This review aimed to provide qualitative evidence supporting existing systematic reviews in this area.

OBJECTIVE

The aim of this QES was to explore key stakeholders' experiences and perceptions of VR for older adults living with dementia. It aimed to explore the barriers and facilitators to VR use and provide recommendations for future design and implementation.

METHODS

QES was used, which involved a systematic search of 6 databases to identify studies that qualitatively explored key stakeholders' experiences and perceptions of VR for older adults living with dementia. Thematic synthesis was used to integrate the findings of 14 studies (from 15 reports). The Critical Appraisal Skills Programme tool was used to assess the methodological quality of the included studies. The confidence placed in the review findings was assessed using the GRADE-CERQUAL (Confidence in the Evidence from Reviews of Qualitative research).

RESULTS

A total of 15 reports from 14 studies were included in the review, consisting of a range of levels of VR immersion, stages of dementia, and care contexts. Three analytical themes were generated: stepping into virtuality, a virtual world, and returning to reality. The results indicate the importance of sensitively designing and introducing VR to this population, as older adults living with dementia often have no prior experience of using this technology. VR can be a positive experience for older adults living with dementia and can provide meaningful interactions, positive expressions, and long-term impacts on everyday functioning. However, it should be acknowledged that some negative associations must be accounted for before, during, and after use.

CONCLUSIONS

This review highlights the positive implications as well as negative associations of VR use. It emphasizes the need for VR design and implementation driven by the needs and views of older adults living with dementia as well as with other key stakeholders. Future research needs to explore the vital role that older adults living with dementia can play in the design process and how they can be empowered to meaningfully design and use this technology.

Older Adults' Experiences and Perceptions of Immersive Virtual Reality: Systematic Review and Thematic Synthesis

BACKGROUND

Immersive virtual reality (IVR) can be defined as a fully computer-generated environment shown on a head-mounted display. Existing research suggests that key features of IVR can assist older adults in their everyday lives, providing opportunities for health promotion and tackling social isolation and loneliness. There has been a surge in qualitative studies exploring older adults' experiences and perceptions of IVR. However, there has been no systematic synthesis of these studies to inform the design of new, more accessible IVR technologies.

OBJECTIVE

This study aimed to systematically review and synthesize qualitative studies exploring older adults' experiences and perceptions of IVR.

METHODS

A systematic review and thematic synthesis were conducted following the ENTREQ (Enhancing Transparency in Reporting the Synthesis of Qualitative Research) guidelines. In total, 2 reviewers completed title and abstract screening, full-text screening, data extraction, and quality appraisal. Thematic synthesis is derived from the qualitative method, thematic analysis. It involves 3 key steps: initial coding and grouping of these codes, the formation of descriptive themes from these codes, and going beyond these data to form analytical themes. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation-Confidence in the Evidence from Reviews of Qualitative Research approach.

RESULTS

Overall, 13 studies were included in the final synthesis, including 224 participants across 9 countries and 5 continents. Confidence in the evidence ranged from high to moderate. Three descriptive themes were generated: practical aspects of IVR use, experiencing unique features of IVR, and perceptions of IVR. The findings from the descriptive themes suggested that there are several improvements that need to be made to existing IVR devices to facilitate older adults' use of this technology. However, older adults' responses to IVR were generally positive. Three analytical themes were generated: tolerating the bad to experience the good, buying in to IVR (don't judge a book by its cover), and "it proves to me I can do it." The analytical themes illustrated that older adults were willing to tolerate discomforts that accompany existing IVR technologies to experience features such as immersive social networking. There was a discrepancy between older adults' perceptions of IVR before use-which were generally negative-and after use-which were generally positive-and IVR provided a platform for older adults to access certain activities and environments more easily than in the real world because of limitations caused by aging.

CONCLUSIONS

This review offers insights into older adults' experiences and perceptions of IVR and suggests how a few improvements to its existing hardware and software as well as how it is first presented could offer new opportunities for older adults to take part in meaningful activities tailored to their needs and preferences.

Digital Technologies to Prevent Social Isolation and Loneliness in Dementia: A Systematic Review

Background: Dementia poses significant and sustained challenges to global society. Diagnosis can lead to increased feelings of loneliness and social isolation. People with dementia living alone are particularly at risk. Considering the growing number of technologies proposed to aid people with dementia address social isolation and loneliness, we reviewed the existing literature. Objective: To collate and summarize current evidence for digital technologies to prevent social isolation and loneliness for people with dementia. Methods: Following the PRISMA guidelines, we systematically searched five databases to identify studies of digital technologies designed to support or prevent social isolation or loneliness for people with dementia. Pre-specified outcomes included social isolation, loneliness, and quality of life. We used deductive thematic analysis to synthesize the major themes emerging from the studies. Results: Ten studies met our inclusion criteria where all studies reported improvements in quality of life and seven reported benefits regarding social inclusion or a reduction in loneliness. Technologies were varied across purpose, delivery format, theoretical models, and levels of personalization. Two studies clearly described the involvement of people with dementia in the study design and five technologies were available outside the research context. Conclusion: There is limited— but increasing— evidence that technologies hold potential to improve quality of life and reduce isolation/loneliness for people with dementia. Results presented are largely based in small-scale research studies. Involvement of people with dementia was limited and few research concepts are reaching implementation. Closer collaboration with people with dementia to provide affordable, inclusive, and person-centered solutions is urgently required.

The Long-term Effects of Immersive Virtual Reality Reminiscence in People With Dementia: Longitudinal Observational Study

Background

Novel nonpharmacological therapies are being developed to prevent cognitive decline and reduce behavioral and psychological symptoms in patients with dementia. Virtual reality (VR) reminiscence was reported to improve anxiety, apathy, and cognitive function immediately after intervention in individuals at residential aged care facilities. However, its effect on elderly patients with dementia and how long this effect could last remain unknown.

Objective

The aim of this paper is to investigate the effect of immersive VR reminiscence in people with dementia both immediately after and 3-6 months after intervention.

Methods

A pilot study was conducted in 2 dementia care units. VR reminiscence therapy sessions were conducted twice per week for a 3-month period. Cognitive function, global status, depressive symptoms, and caregiver burden were assessed before and immediately after VR intervention in 20 participants. Subsequently, 7 participants were reassessed 3-6 months after the VR intervention. Wilcoxon sign-rank test was used for statistical comparisons of the changes.

Results

There were no significant changes in cognitive function, global status, and caregiver burden immediately after the VR intervention, but there was a significant reduction in depressive symptoms (P=.008). Moreover, compared with the cognitive function immediately after VR, it kept declining 3-6 months after.

Conclusions

Immersive VR reminiscence can improve mood and preserve cognitive function in elderly patients with dementia during the period of the intervention. Studies using a control group and comparing the use of VR with traditional forms of reminiscence should be conducted in the future to confirm and expand on these findings.

Design Considerations for Immersive Virtual Reality Applications for Older Adults: A Scoping Review

Immersive virtual reality (iVR) has gained considerable attention recently with increasing affordability and accessibility of the hardware. iVR applications for older adults present tremendous potential for diverse interventions and innovations. The iVR literature, however, provides a limited understanding of guiding design considerations and evaluations pertaining to user experience (UX). To address this gap, we present a state-of-the-art scoping review of literature on iVR applications developed for older adults over 65 years. We performed a search in ACM Digital Library, IEEE Xplore, Scopus, and PubMed (1 January 2010–15 December 2019) and found 36 out of 3874 papers met the inclusion criteria. We identified 10 distinct sets of design considerations that guided target users and physical configuration, hardware use, and software design. Most studies carried episodic UX where only 2 captured anticipated UX and 7 measured longitudinal experiences. We discuss the interplay between our findings and future directions to design effective, safe, and engaging iVR applications for older adults.

Application Effect of Motion Capture Technology in Basketball Resistance Training and Shooting Hit Rate in Immersive Virtual Reality Environment

With the progress of society, sports have become the mainstream of social development. Strengthening the athletic ability of basketball players can effectively improve their shooting percentage. Firstly, virtual reality (VR) technology and motion capture technology are summarized. Secondly, the resistance training and shooting training of basketball players are analyzed and explained. Finally, the algorithm of motion capture technology is designed to capture and optimize the movements of athletes. In addition, a comprehensive evaluation of the shooting percentage of basketball players is carried out. The results show that the motion capture technology proposed here effectively captures the shooting action of basketball players, and the shooting percentage of players is promoted through resistance training. Among all athletes, the highest shooting percentage improvement is around 14% and the lowest is around 4%. In all groups, athletes of different heights have the largest difference in the improvement of shooting percentage. Therefore, this work plays an important role in improving the shooting rate of basketball players through VR technology. It provides technical support for improving the shooting percentage of basketball players and contributes to the progress of athletes' comprehensive athletic ability.

Influence of Rural Development of River Tourism Resources on Physical and Mental Health and Consumption Willingness in the Context of COVID-19

This study took the Three Gorges Dam as an example and discussed the influence of river regulation decisions on the sustainable development of surrounding villages. The study used mixed research methods, snowball sampling, and convenience sampling to obtain samples. The questionnaire samples were analyzed by basic statistical tests, t-test, and structural equation modeling (SEM). The respondents’ opinions were collected through semi-structured interviews and finally the results were discussed by multivariate analysis. The findings were that even though the villages were not well developed in terms of economy, environment, and natural ecology, as long as the community security could be stable, the living could be safe and convenient, people’s daily life patterns and leisure behaviors could be maintained, and people could stabilize their minds and emotions and maintain physical and mental health in order to meet their living needs and reduce the burden. There would be time and funds to invest in leisure, tourism activities, and consumption behavior. If the above consumption patterns are continued, people will gain positive perceptions, stimulating people’s willingness to invest in property purchases or to make travel plans again.

Shared Virtual Reality Experiences during the COVID-19 Pandemic: Exploring the Gratifications and Effects of Engagement with Immersive Videos

The coronavirus (COVID-19) pandemic and recent economic recession have been impacting many people’s mental health. The experience of social distancing created new hardships for people who already reported symptoms of depression or anxiety. In these circumstances, new technologies, such as immersive virtual reality (VR) videos, could serve as useful tools for facilitating interactions, emotional sharing, and information processing within a virtual environment. In this study, researchers aimed to enrich the information processing literature by focusing on the uses and gratifications of 360-degree VR videos during the pandemic. Through employing survey research with 1422 participants located in the U.S. and structural equation modeling for data analysis, this study found that five types of gratification, including utilitarian (i.e., navigation), hedonic (i.e., enjoyment), sensual (i.e., realism), social (i.e., community), and symbolic (i.e., coolness), significantly motivated users to use such immersive videos. Simultaneously, data demonstrated that these five types of gratification could influence users’ cognitive engagement with virtual content. In addition, such VR engagement facilitated users’ positive attitudes toward immersive videos and continued usage of them. The findings provided practical implications for COVID-19 global recovery as well.

Implementation of a Virtual Reality recreation program in long-term care

Introduction

This manuscript describes the implementation of a Virtual Reality (VR) recreation program at long-term care sites across Ontario, Canada, using the RE-AIM Framework to guide the implementation and its evaluation.

Methods

We developed a VR recreation program to enhance the lives of long-term care residents, through 3 sequential phases. In Phase 1, we learned about resident and staff needs through focus groups, staff surveys and observations. In Phase 2, we developed 10 VR experiences, based on the data from Phase 1. In Phase 3, we implemented the VR experiences and supporting manual and measured their implementation, using the RE-AIM Framework.

Results

We found the VR program to be highly (but not consistently) implementable across all sites. Factors that supported implementation were the following: resident interest in the content and technology, relative ease of use for staff to implement and formally integrating VR into the recreation calendar. Factors that impeded implementation were the following: the size of the headset, inability for the headset to cast given the sites' Information Technology infrastructure and some content that was not engaging.

Conclusions

VR programs are highly implementable and this implementation is enhanced by integration of the program into existing recreational systems, ease of use and resident engagement.

Virtual reality and well-being in older adults: Results from a pilot implementation of virtual reality in long-term care

Introduction

This paper describes the findings of a pilot implementation project that explored the potential of virtual reality (VR) technology in recreational programming to support the well-being of older adults in long-term care (LTC) homes.

Methods

32 Adults in four LTC homes participated in a pilot implementation project where they viewed VR experiences of popular locations in Canada created especially for this project. Data in this paper are based on multiple viewing experiences (n = 102) over a two-week period.

Results

VR appeared to be an effective distraction from pain for the participants. Participants of this study found the VR experiences to be enjoyable and were relaxed and happy while viewing them. Most participants were attentive or focused while viewing the VR experiences, and the experiences were found to be a source of reminiscence for some of the participants. Participants related well to others around them during a majority of the experiences and the VR experiences were a point of conversation between the staff and the participants.

Conclusion

The findings from this pilot implementation reveal that VR shows potential to enhance the physical, emotional, cognitive, and social well-being of older adults living in LTC, including those living with cognitive impairment.

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.

Technology-Mediated Enrichment in Aged Care: Survey and Interview Study

Background

Digital technologies such as virtual reality (VR), humanoid robots, and digital companion pets have the potential to provide social and emotional enrichment for people living in aged care. However, there is currently limited knowledge about how technologies are being used to provide enrichment, what benefits they provide, and what challenges arise when deploying these technologies in aged care settings.

Objective

This study aims to investigate how digital technologies are being used for social and emotional enrichment in the Australian aged care industry and identify the benefits and challenges of using technology for enrichment in aged care.

Methods

A web-based survey (N=20) was distributed among people working in the Australian aged care sector. The survey collected information about the types of technologies being deployed and their perceived value. The survey was followed by semistructured interviews (N=12) with aged care workers and technology developers to investigate their experiences of deploying technologies with older adults living in aged care. Survey data were analyzed using summary descriptive statistics and categorizing open-ended text responses. Interview data were analyzed using reflexive thematic analysis.

Results

The survey revealed that a range of commercial technologies, such as VR, tablet devices, and mobile phones, are being used in aged care to support social activities and provide entertainment. Respondents had differing views about the value of emerging technologies, such as VR, social robots, and robot pets, but were more united in their views about the value of videoconferencing. Interviews revealed 4 types of technology-mediated enrichment experiences: enhancing social engagement, virtually leaving the care home, reconnecting with personal interests, and providing entertainment and distraction. Our analysis identified 5 barriers: resource constraints, the need to select appropriate devices and apps, client challenges, limited staff and organizational support, and family resistance.

Conclusions

This study demonstrates that technologies can be used in aged care to create personally meaningful enrichment experiences for aged care clients. To maximize the effectiveness of technology-mediated enrichment, we argue that a person-centered care approach is crucial. Although enrichment experiences can be created using available technologies, they must be carefully selected and co-deployed with aged care clients. However, significant changes may be required within organizations to allow caregivers to facilitate individual technology-based activities for enrichment.

Re-thinking reablement strategies for older adults in residential aged care: a scoping review

BACKGROUND

The number of older adults in residential aged care is increasing. Aged care residents have been shown to spend most of the day sedentary and have many co-morbidities. This review aimed to systematically explore the effectiveness of reablement strategies in residential aged care for older adults' physical function, quality of life and mental health, the features of effective interventions and feasibility (compliance, acceptability, adverse events and cost effectiveness).

METHOD

This scoping review was undertaken according to PRISMA guidelines (extension for scoping reviews). Five e-databases (Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and CINAHL) were searched from 2010 onwards. Randomised controlled trials investigating reablement strategies addressing physical deconditioning for older adults (mean age ≥ 65 yrs) in residential aged care on physical function, quality of life or mental health were included. Feasibility of the interventions (compliance, acceptability, satisfaction, adverse events and cost effectiveness) was explored.

RESULTS

Five thousand six hundred thirty-one citations were retrieved, and 63 studies included. Sample sizes ranged from 15 to 322 and intervention duration from one to 12 months. Exercise sessions were most often conducted two to three times per week (44 studies) and physiotherapist-led (27 studies). Interventions were predominately multi-component (28 studies, combinations of strength, balance, aerobic, functional exercises). Five interventions used technology. 60% of studies measuring physical function reported significant improvement in the intervention versus control, 40% of studies measuring quality of life reported significant improvements in favour of the intervention, and 26% of studies measuring mental health reported significant intervention benefits. Over half of the studies measured compliance and adverse events, four measured acceptability and none reported cost effectiveness.

CONCLUSIONS

There has been a research surge investigating reablement strategies in residential aged care with wide variability in the types and features of strategies and outcome measures. Few studies have measured acceptability, or cost effectiveness. Exploration of core outcomes, mapping stakeholders and co-designing a scalable intervention is warranted.

Immersive Virtual Reality for Older Adults

Despite the proliferation of research on immersive virtual reality (IVR) technologies for older adults, comprehensive guidelines on designing immersive and engaging VR for older adults remain sparse. Therefore, we first compounded 67 guidelines based on published literature. Next, to empirically ground these design recommendations, we provided 37 older adults of diverse ages, education levels, and cognitive abilities with a first VR experience. Analyzing interviews with the 37 older adults via the Laddering method, we found that they generally reported positive experiences with their first VR exposure. With these deepened insights, we reflect on, nuance, and contextualize existing design guidelines, and formulate points to bear in mind when designing accessible and engaging VR experiences for older persons.

Feasibility of Group-Based Multiple Virtual Reality Sessions to Reduce Behavioral and Psychological Symptoms in Persons Living in Residential Aged Care

OBJECTIVES

To assess the feasibility of using group-based fully immersive virtual reality (VR) across multiple sessions to reduce behavioral and psychological symptoms (BPSs), including depression, anxiety, and agitated behaviors, in cognitively diverse aged care residents.

DESIGN

A 6-session feasibility trial was conducted within a residential aged care facility using convenience sampling to recruit N = 25 residents of varying cognitive capacity. Groups of 5 residents viewed 360-degree videos on a wireless head-mounted display to provide fully immersive VR experiences.

SETTING AND PARTICIPANTS

Half of the participants recruited from the 160-bed facility had a diagnosis of dementia (48%), whereas assessment with the Psychogeriatric Assessment Scale for cognitive impairment revealed that 64% experienced cognitive impairment (mild 20%, moderate 16%, and severe 28%). Additionally, 32% of participants had an existing anxiety or depression diagnosis.

MEASURES

The Cornell Scale for Depression in Dementia, Generalized Anxiety Disorder 7-item, and Cohen Mansfield Agitation Inventory-Short were used to assess changes in persisting BPS pre- to postintervention period. The Person-Environment Apathy Rating apathy subscale, Observed Emotions Rating Scale, and a visual analog scale (Smileometer) were used to assess immediate mood responses from residents at every VR session. VR tolerability and resident feedback was also recorded.

RESULTS

Pleasure (z = -5.892, P < .001) and general alertness (z = -2.455, P = .014) of participants improved at VR sessions, whereas apathy diminished (z = -5.275, P < .001). Compared to baseline, post-intervention depression was significantly lowered (z = -2.60, P = .009), whereas agitation increased (z = -2.98, P = .003). No significant changes in anxiety were observed. The quality of 360-degree videos and the device used did not induce any major VR-related negative side effects.

CONCLUSIONS AND IMPLICATIONS

Overall group-based VR reduced depressive symptoms and apathy, and induced a positive emotional response in most residents, with few observed side effects. Results indicate feasibility of group-based VR technological innovation within RAC.

Using Medical Device Standards for Design and Risk Management of Immersive Virtual Reality for At-Home Therapy and Remote Patient Monitoring

Numerous virtual reality (VR) systems have received regulatory clearance as therapeutic medical devices for in-clinic and at-home use. These systems enable remote patient monitoring of clinician-prescribed rehabilitation exercises, although most of these systems are nonimmersive. With the expanding availability of affordable and easy-to-use head-mounted display (HMD)-based VR, there is growing interest in immersive VR therapies. However, HMD-based VR presents unique risks. Following standards for medical device development, the objective of this paper is to demonstrate a risk management process for a generic immersive VR system for remote patient monitoring of at-home therapy. Regulations, standards, and guidance documents applicable to therapeutic VR design are reviewed to provide necessary background. Generic requirements for an immersive VR system for home use and remote patient monitoring are identified using predicate analysis and specified for both patients and clinicians using user stories. To analyze risk, failure modes and effects analysis, adapted for medical device risk management, is performed on the generic user stories and a set of risk control measures is proposed. Many therapeutic applications of VR would be regulated as a medical device if they were to be commercially marketed. Understanding relevant standards for design and risk management early in the development process can help expedite the availability of innovative VR therapies that are safe and effective.

Effects of user experiences on continuance intention of using immersive three-dimensional virtual reality among institutionalized older adults

AIM

To evaluate the acceptance of three-dimensional virtual reality programs and to explore the factors influencing the acceptance of the programs among the institutionalized older adults.

DESIGN

A cross-sectional explanatory study.

METHODS

A total of 71 residents completed the program successfully. They were invited to join a 9-week program included eight activities related to horticultural therapy in a virtual environment. Data were collected by structured questionnaires from August 2018 to February 2019. Ten association hypotheses were derived from the literature review. Partial least squares structural equation modelling was used to examine the proposed hypotheses.

RESULTS

Program acceptance was defined as virtual reality practices and continuous usage intention. Frequency of practice was about 12 times during 9-week free-trial period, and the score of continuance usage intention was 13.06 (maximum value of 15). The findings indicated that virtual reality practices were significantly affected by presence and the presence was significantly affected by involvement and interactivity. Continuance usage intention was significantly affected by involvement; and involvement was significantly affected by interactivity. However, continuance usage intention was not significantly influenced by virtual reality practices.

CONCLUSIONS

The findings supported that immersive three-dimensional virtual reality program was accepted by the institutionalized older adults. The acceptance, in terms of virtual reality practices and continuous usage intention, was influenced by different paths. The findings have a potential impact on the design of virtual reality technology for the care of institutionalized older adults.

IMPACT

What problem did the study address? There were controversial findings about the acceptance of immersive 3D virtual reality program among older adults. What were the main findings? Interactivity advanced the sense of presence and, thus, resulted in a higher frequency of virtual reality practices. Interactivity enhanced perception of involvement, thus, contributing to an increased intention of continuous usage Where and on whom will the research have an impact? The immersive 3D virtual reality program was appropriate for older adults, even for first time users or individuals aged over 80 years. The findings revealed new insights for developing immersive 3D virtual reality programs for the older adults.

Virtual visits: Reminiscence in residential aged care with digital mapping technologies

OBJECTIVE

Digital technologies can support reminiscence and lifestyle enrichment in residential aged care. This study explores potential benefits and risks of virtual visits using digital maps, tablet computers and virtual reality technologies.

METHODS

Reminiscence sessions were conducted with metropolitan aged care facility residents (n = 7), using digital mapping applications to 'visit' places of personal significance. Residents and family members (n = 4) were interviewed.

RESULTS

Some older adults found virtual visits valuable and all reminisced in various ways about personal, family and social experiences. Family members felt that virtual visits would be enriching for loved ones and that they supported sharing of life stories. Our results also highlight that VR usability improvements are needed to better suit older people.

CONCLUSIONS

Virtual visits could offer valuable opportunities for positive reminiscence for some older adults in residential aged care. Digital technologies need to provide better support for older users and people who assist them.

Using Virtual Reality to Improve Apathy in Residential Aged Care: Mixed Methods Study

Background

Apathy is a common symptom in neurological disorders, including dementia, and is associated with a faster rate of cognitive decline, reduced quality of life, and high caregiver burden. There is a lack of effective pharmacological treatments for apathy, and nonpharmacological interventions are a preferred first-line approach to treatment. Virtual reality (VR) using head-mounted displays (HMDs) is being successfully used in exposure- and distraction-based therapies; however, there is limited research on using HMDs for symptoms of neurological disorders.

Objective

This feasibility study aimed to assess whether VR using HMDs could be used to deliver tailored reminiscence therapy and examine the willingness to participate, response rates to measures, time taken to create tailored content, and technical problems. In addition, this study aimed to explore the immediate effects between verbal fluency and apathy after exposure to VR.

Methods

A mixed methods study was conducted in a sample of older adults residing in aged care, and 17 participants were recruited. Apathy was measured using the Apathy Evaluation Scale (AES), and verbal fluency was used as a proxy measure of improvements in apathy and debriefing interviews to assess feedback from participants. Side effects that can occur from using HMDs were also measured.

Results

We recruited participants from a high socioeconomic status setting with a high education level, and the participation rate was 85% (17/20); most responses to measures were positive. Access to a wide range of freely available content and the absence of technical difficulties made the delivery of a VR reminiscence intervention highly feasible. Participants had improved semantic scores (t₁₄=−3.27; P=.006) but not phonemic fluency scores (t₁₄=0.55; P=.59) immediately after the intervention. Those with higher levels of apathy demonstrated the greatest cognitive improvements after a VR reminiscence experience, which was indicated by a strong positive relationship between the AES and semantic verbal fluency change scores postminus pre-VR (r=0.719; 95% CI 0.327 to 0.900; P=.003). All participants enjoyed the experience despite 35% (6/17) of participants experiencing temporary side effects.

Conclusions

This study provides initial evidence that it is feasible to use VR with HMDs for therapy to treat symptoms of apathy in older adults in residential aged care. However, there is a need to closely monitor the side effects of HMD use in older adults. Further research is needed using an active control group to compare the use of VR with traditional forms of reminiscence therapy.
