A Pilot Study of an In-Home Multicomponent Exergame Training for Older Adults: Feasibility, Usability and Pre-Post Evaluation

Player Experience Evaluation in Game-Based Systems for Older Adults

Significant efforts are currently being made to improve the quality of life of the older adult population. These efforts focus on aspects such as health, social interaction, and mental health. One of the approaches that has shown positive results in several studies is the application of game-based systems. These systems are not only used for entertainment, but also as tools for learning and promoting positive feelings. They are a means to overcome loneliness and isolation, as well as to improve health and provide support in daily life. However, it is important to note that, while these experiences are gradually being introduced to the older adult population, they are often designed with a younger audience in mind who are assumed to be more technologically proficient. This supposition can make older adults initially feel intimidated when interacting with this type of technology, which limits their ability to fully utilize and enjoy these technological solutions. Therefore, the purpose of this article is to apply a game experience and fun evaluation process oriented toward the older adult population based on the playability theory of human-computer interaction in virtual reality game experiences. This is expected to offer highly rewarding and pleasurable experiences, which will improve engagement with the older population and promote active and healthy aging.

Assessing the Clinical Effectiveness of an Exergame-Based Exercise Training Program Using Ring Fit Adventure to Prevent and Postpone Frailty and Sarcopenia Among Older Adults in Rural Long-Term Care Facilities: Randomized Controlled Trial

BACKGROUND

Frailty and sarcopenia are geriatric syndromes of increasing concern and are associated with adverse health outcomes. They are more prevalent among long-term care facility (LTCF) users than among community dwellers. Exercise, especially multicomponent and progressive resistance training, is essential for managing these conditions. However, LTCFs, particularly in rural areas, face challenges in implementing structured exercise programs due to health care professional shortages. Moreover, older adults often become bored with repetitive exercise training and may lose interest over time. The Nintendo Switch Ring Fit Adventure (RFA) exergame is a novel exergame that combines resistance, aerobic, and balance exercises and offers a potential solution by boosting motivation in an immersive manner and reducing staff intervention needs.

OBJECTIVE

We aimed to evaluate the clinical effectiveness of an exergame-based exercise training program delivered via RFA (exergame-RFA) in improving muscle mass and functional performance among older adult LTCF users.

METHODS

This was a randomized controlled trial conducted from August 2022 to September 2023 and involved older adult LTCF users (aged ≥60 y) in rural southern Taiwan. Participants were randomized into an intervention group (exergame-RFA plus standard care) or a control group (standard care alone). The intervention, conducted seated with arm fit skills and trunk control exercises using the RFA, lasted 30 minutes twice weekly over 12 weeks. The primary outcomes measured were the Study of Osteoporotic Fractures index (serving as an indicator of frailty status) and the diagnostic criteria for sarcopenia (appendicular skeletal muscle mass index, handgrip strength, and gait speed). The secondary outcomes included functional performance (box and block test as well as maximum voluntary isometric contraction of the dominant upper extremity), muscle condition (muscle thickness measured using ultrasonography), activities of daily living (Kihon checklist), health-related quality of life (Short Form Health Survey-36), and cognitive function (brain health test). We used an intention-to-treat analysis, incorporating a simple imputation technique in statistical analysis. A mixed ANOVA, with time as a within-participant factor and intervention as a between-participant factor, was used to compare the training effects on outcomes.

RESULTS

We recruited 96 individuals, of whom 60 (62%) underwent randomization. Of these 60 participants, 55 (92%) completed the study. Significant group×time interactions were observed in the intervention group in all primary outcomes (all P<.001, except P=.01 for handgrip strength) and most secondary outcomes, including maximum voluntary isometric contraction of the biceps (P=.004) and triceps brachii (P<.001) muscles, biceps muscle thickness measured using ultrasonography (P<.001), box and block test (P<.001), Kihon checklist (physical function: P=.01, mood status: P=.003, and total: P=.003), and brain health test (P<.001).

CONCLUSIONS

The exergame-RFA intervention significantly improved muscle mass, strength, and functional performance among older adult users of rural LTCFs, offering a novel approach to addressing frailty and sarcopenia.

Experiences of older adults participating in dance exergames: A systematic review and meta-synthesis

BACKGROUND

Interventions to encourage adequate physical activity amongst older adults have had limited long-term success. Dancing and exergames, two beneficial and enjoyable physical activities for older adults, may make regular exercise more interesting and effective. Dance exergames are physical exercises that integrate sensory, cognitive, psychological, and physical functions by requiring users to interact with game scenarios through deliberate body motions and receive real-time feedback. They provide an inherently enjoyable gaming and workout experience, which may boost exercise adherence. However, little is known about older adults' experiences with dance exergames.

OBJECTIVE

To synthesise the qualitative experiences of older adults participating in dance exergames.

DESIGN

Systematic review and meta-synthesis.

METHODS

Dance exergame studies (peer-reviewed and grey literature) involving older adults in any setting published in English from inception to 17 August 2023 were included. Qualitative or mixed-method studies must use immersive or non-immersive virtual-reality platforms. PubMed, Scopus, CINAHL, The Cochrane Library, ProQuest Dissertations & Theses Global, Google Scholar, and reference lists of relevant studies and reviews were searched for eligible studies. The search strategy for Scopus was: (TITLE-ABS-KEY (danc*) AND TITLE-ABS-KEY (exergames OR exergame OR video AND games OR virtual AND reality) AND TITLE-ABS-KEY (older AND adults OR elderly OR seniors OR geriatrics)). Thematic synthesis by Thomas and Harden was used for meta-synthesis.

RESULTS

Eleven studies (n = 200 older adults) were included. Three themes and 14 subthemes were synthesised: 1) Dance exergames as dual-task training for physical, cognitive, and psychological well-being, 2) Concerns on usability issues, and 3) Possible enhancements of dance exergames. Older adults recognised that dance exergames could improve their physical, cognitive, and psychological well-being. Existing dance exergame systems had several usability issues. For example, some older adults were unfamiliar with using new technology and had trouble in navigating the game systems. The older adults also provided various suggestions for adaptation to their age group, such as ensuring a variety of dances, difficulty levels suited for older adults' cultural backgrounds, and physical and cognitive capabilities.

CONCLUSIONS

Dance exergames may be an attractive way to encourage older adults to exercise, but appropriate modifications are needed. When designing/selecting dance exergames for older persons, researchers, healthcare professionals, and senior care centres should consider using exergames that have simple designs, varied dances that are locally adapted, and appeal to a large proportion of older adults.

Alexa, let's train now! - A systematic review and classification approach to digital and home-based physical training interventions aiming to support healthy cognitive aging

BACKGROUND

There is mounting evidence that regular physical activity is an important prerequisite for healthy cognitive aging. Consequently, the finding that almost one-third of the adult population does not reach the recommended level of regular physical activity calls for further public health actions. In this context, digital and home-based physical training interventions might be a promising alternative to center-based intervention programs. Thus, this systematic review aimed to summarize the current state of the literature on the effects of digital and home-based physical training interventions on adult cognitive performance.

METHODS

In this pre-registered systematic review (PROSPERO; ID: CRD42022320031), 5 electronic databases (PubMed, Web of Science, PsycInfo, SPORTDiscus, and Cochrane Library) were searched by 2 independent researchers (FH and PT) to identify eligible studies investigating the effects of digital and home-based physical training interventions on cognitive performance in adults. The systematic literature search yielded 8258 records (extra 17 records from other sources), of which 27 controlled trials were considered relevant. Two reviewers (FH and PT) independently extracted data and assessed the risk of bias using a modified version of the Tool for the assEssment of Study qualiTy and reporting in EXercise (TESTEX scale).

RESULTS

Of the 27 reviewed studies, 15 reported positive effects on cognitive and motor-cognitive outcomes (i.e., performance improvements in measures of executive functions, working memory, and choice stepping reaction test), and a considerable heterogeneity concerning study-related, population-related, and intervention-related characteristics was noticed. A more detailed analysis suggests that, in particular, interventions using online classes and technology-based exercise devices (i.e., step-based exergames) can improve cognitive performance in healthy older adults. Approximately one-half of the reviewed studies were rated as having a high risk of bias with respect to completion adherence (≤85%) and monitoring of the level of regular physical activity in the control group.

CONCLUSION

The current state of evidence concerning the effectiveness of digital and home-based physical training interventions is mixed overall, though there is limited evidence that specific types of digital and home-based physical training interventions (e.g., online classes and step-based exergames) can be an effective strategy for improving cognitive performance in older adults. However, due to the limited number of available studies, future high-quality studies are needed to buttress this assumption empirically and to allow for more solid and nuanced conclusions.

A Newly Developed Exergame-Based Telerehabilitation System for Older Adults: Usability and Technology Acceptance Study

BACKGROUND

Telerehabilitation has gained significance as a tool to deliver and supervise therapy and training as effective as traditional rehabilitation methods yet more accessible and affordable. An exergame-based telerehabilitation system has recently been developed within the scope of the international Continuum-of-Care (COCARE) project. The system comprises training devices for use in clinics (Dividat Senso) and at home (Dividat Senso Flex), an assessment system, and a rehabilitation cockpit, and its focus lies on home-based motor-cognitive training, which is remotely managed by health care professionals (HPs).

OBJECTIVE

This study aims to analyze the usability, acceptance, and enjoyment of the COCARE system from the perspective of primary (older adults [OAs]) and secondary (HPs) end users.

METHODS

At 3 trial sites (located in Switzerland, Italy, and Cyprus), participants engaged in a single-session trial of the COCARE system, including testing of exergames and assessments. Mixed methods encompassing qualitative approaches (eg, think aloud) and quantitative measures (eg, Exergame Enjoyment Questionnaire [EEQ], System Usability Scale [SUS], and Unified Theory of Acceptance and Use of Technology [UTAUT] questionnaire) were used to analyze participants' perceptions of the system and identify potential barriers to its implementation in a home setting. In addition, the associations of performance during gameplay and assessments, demographics, and training motivation (Behavioral Regulation in Exercise Questionnaire-3 [BREQ-3]) with usability, acceptance, and enjoyment were explored.

RESULTS

A total of 45 OAs and 15 HPs participated in this study. The COCARE system achieved good acceptance ratings (OAs: 83%, range 36%-100% and HPs: 81%, range 63.8%-93.3% of the maximum score), and OAs indicated high enjoyment (mean 73.3, SD 12.7 out of 100 points in the EEQ) during the exergame session. The system's usability, assessed with the SUS, received scores of 68.1 (SD 18.8; OAs) and 70.7 (SD 12.3; HPs) out of 100 points, with substantial differences observed between the trial sites. Several requirements for improvement were identified. Commonly mentioned barriers to adoption included the movement-recognition sensitivity of the Senso Flex, its limited markings, and difficulties in understanding certain instructions for assessments and games. Performance in games and assessments showed the highest significant correlations with the SUS (Spearman ρ=0.35, P=.02 to ρ=0.52, P<.001). The BREQ-3 had significant correlations with all usability measures, thereby even large significant correlations with enjoyment (Spearman ρ=0.58; P<.001). Age had moderately significant correlations with the SUS (Spearman ρ=-0.35; P=.02) and the UTAUT total score (ρ=-0.35; P=.02) but no significant correlation with the EEQ. Concerning sex and years of education, no significant correlations were found.

CONCLUSIONS

The study's findings will inform the further development of the COCARE system toward a user-friendly and widely accepted version, enhancing cognitive and physical functions in OAs. Future randomized controlled trials should evaluate the system's feasibility and effectiveness.

Home-Based Virtual Reality Exergame Program after Stroke Rehabilitation for Patients with Stroke: A Study Protocol for a Multicenter, Randomized Controlled Trial

It is essential for stroke patients to maintain their therapy even after discharging inpatient rehabilitation. This is because recovery is an ongoing process that requires consistent effort. Virtual reality exergame training (VRET) is becoming widely used in stroke rehabilitation to improve physical, social, and psychological outcomes. Home-based VRET may be a more convenient and accessible option for stroke rehabilitation. This study will aim to determine the effectiveness of home-based VRET for patients with stroke who have been discharged from the hospital. This trial will randomly assign 120 participants to 8 weeks of either a VRET (intervention group) or daily life (control group). The study will measure cardiopulmonary endurance, muscular strength, functional capacity, gait, activities of daily living, and quality of life. Our main objective is to determine whether it is safe for patients to undergo VRET at home after they have been discharged from the hospital with a doctor's note. Additionally, we aim to examine whether stroke patients are capable of exercising at home after being discharged from the hospital. This study's outcome could pave the way for developing more comprehensive exercise protocols for stroke patients. Our findings will provide valuable insights into the efficacy of VRET as a therapeutic tool for stroke patients.

Feasibility and Effectiveness of a Personalized Home-Based Motor-Cognitive Training Program in Community-Dwelling Older Adults: Protocol for a Pragmatic Pilot Randomized Controlled Trial

BACKGROUND

Exergame-based motor-cognitive training in older adults has been associated with improvements in physical, cognitive, and psychological functioning. The novel Cocare system (Dividat GmbH), developed through a user-centered design process, allows motor-cognitive training in a telerehabilitation setting. It includes (1) a stationary stepping platform for supervised exergame training (Dividat Senso; Dividat GmbH), (2) a home-based version (Dividat Senso Flex, which is a rollable pressure-sensitive mat; Dividat GmbH), (3) an assessment system (including motor-cognitive tests), and (4) a rehabilitation cockpit for remote training supervision and management.

OBJECTIVE

The aim of this study is to test the feasibility and effectiveness of this novel training system.

METHODS

A total of 180 older adults from Switzerland, Italy, and Cyprus aged ≥60 years with a prescription for rehabilitation are randomly allocated to an intervention group or a control group. Both groups continue with their usual care, whereas participants in the intervention group additionally perform a 2-week supervised exergame training program at rehabilitation centers, followed by a 10-week home training program under remote supervision. The assessment system is used to indicate the start level of each participant, and, in both intervention periods, standardized progression rules are applied. The measures of feasibility include adherence, attrition, exergame enjoyment, willingness to perform such a training program, and the number and types of help requests. Effectiveness is assessed in terms of cognitive and physical functioning, balance confidence, and quality of life.

RESULTS

Data collection started in February 2023 and is ongoing. Final measurements are expected to be performed in January 2024.

CONCLUSIONS

Owing to the user-centered design approach, the Cocare system is expected to be user-friendly and offers several novel features to cover the whole continuum of care. This pragmatic trial will provide valuable information regarding final necessary adaptations and subsequent implementation efforts.

Challenges and suggestions for exergaming program in exercise among older adults

Engaging in physical activity and exercise is one of the important ways for health promotion. However, older adults are often physically inactive or have a sedentary lifestyle and have poor compliance with physical activity. Exergaming program with their unique advantages could make physical activity a more joyful experience and motivate older adults to participate in physical activity. Promoting older adults' health through engagement in exergaming programs is still in the early stage, and still faces many challenges. Analyzing the challenges and difficulties faced by exergaming program for older adults and exploring in-depth strategies to promote the implementation of exergaming program for older adults are of great significance for the design and implementation of sports games for older adults.

Usability of exergames as a home-based balance training tool for older adults: protocol for a systematic review

INTRODUCTION

Exergames are used in the clinical practice of geriatric rehabilitation to increase physical activity levels and motivate players/patients. Their use in the home environment makes it possible to perform fun, engaging and interactive training with a large number of repetitions, thereby reducing the negative repercussions of postural imbalance in older adults. The aim of this systematic review is to collate and analyse evidence on the usability of exergames as a tool for home-based balance training for older adults.

METHODS AND ANALYSIS

We will include randomised controlled trials involving healthy older adults (aged 60 years or older) who are described as having impaired static or dynamic balance using any subjective or objective assessment criteria. We will search Web of Science, MEDLINE, Embase, Scopus, ScienceDirect and the Cochrane Library from database inception to December 2022.

CLINICALTRIALS

gov, the WHO International Clinical Trials Registry Platform and ReBEC will be searched for ongoing or unpublished trials. Two independent reviewers will screen the studies and extract the data. The findings will be presented in the text and tables, and if possible, relevant meta-analyses will be performed. The risk of bias and the quality of evidence will be assessed based on the recommendations of the Cochrane Handbook and Grading of Recommendations, Assessment, Development and Evaluation, respectively.

ETHICS AND DISSEMINATION

Ethical approval was not required because of the nature of this study. Findings will be disseminated through peer-reviewed publications, conference presentations and through clinical rehabilitation networks.

Older adults' needs and requirements for a comprehensive exergame-based telerehabilitation system: A focus group study

Introduction

Telerehabilitation in older adults using information and communication technologies (ICTs) provides therapy, which is potentially equally effective as traditional rehabilitation, yet more accessible. This study aimed to analyze the needs and requirements of older adults (OA) and healthcare-professionals (HP) toward ICTs and telerehabilitation in general as well as toward a specific novel exergame-based telerehabilitation system (COCARE system, Dividat).

Materials and methods

The COCARE telerehabilitation system enables individual training based on exergames, as well as an assessment system and a digital centralized case management. Six focus groups with in total 34 participants were conducted. A mixed-methods approach was used comprising questionnaires and semi-structured interviews.

Results

Both OA and HP would engage to an exergame-based telerehabilitation program. Major motivating factors are the relevance of such a training for health and the entertainment component of exergames. Main requirements are simplification of the system, variety, a personalized training, a constantly available contact person, and comprehensive instructions for use. Besides, HP praised the system's motivational effect, but remained concerned about risk of falls and social isolation.

Conclusion

ICTs for telerehabilitation are accepted by OA and HP but should be adapted hardware- and software-wise to address OA' age-stemming vulnerabilities (e.g., risk of falls) and low ICT literacy.

Using exergame-based exercise to prevent and postpone the loss of muscle mass, muscle strength, cognition, and functional performance among elders in rural long-term care facilities: A protocol for a randomized controlled trial

Objective

Elderly individuals in long-term care facilities (LTCFs) have a higher prevalence of sarcopenia than those in the community. Exercise is the gold standard for preventing and treating sarcopenia. Regarding exercise, multicomponent exercises, including progressive resistance training (PRT), are beneficial. However, developing routine, structured exercise programs for the elderly in LTCFs is difficult because of a shortage of healthcare providers, particularly in rural regions. Exergame-based exercises can increase a player's motivation and reduce staff time for an intervention. Nintendo Switch RingFit Adventure (RFA) is a novel exergame that combines resistance, aerobic, and balance exercises. In this study, we aim to investigate the clinical effectiveness of RFA on muscle and functional performance parameters among the elderly in LTCFs.

Methods

The EXPPLORE (using EXergame to Prevent and Postpone the LOss of muscle mass, muscle strength, and functional performance in Rural Elders) trial is a single-center randomized controlled trial involving elderly individuals (≥60 years) living in LTCFs in rural southern Taiwan. The participants will be equally randomized to the intervention group (exergame-based exercise plus standard care) or the control group (standard care alone). Both groups will receive standard care except that the intervention group will receive exergame-based exercises at the time previously scheduled for sedentary activities in the LTCFs. The exergame-based exercise will be performed using RFA in the sitting position with a specialized design, including arm fit skills and knee assist mode. Each session of the exercise lasts 30 mins and will be performed two times per week for 12 weeks. The primary outcomes will be the osteoporotic fracture index, appendicular skeletal muscle mass index, dominant handgrip strength, and gait speed. Meanwhile, the secondary outcomes will be the dexterity and agility, muscle strength and thickness, range of motion of the joints of the dominant upper extremity, Kihon checklist, Medical Outcomes Study 36-Item Short-Form Health Survey, and Brain Health Test.

Discussion

This trial will provide valuable knowledge on whether exergames using RFA can counteract physical decline and improve quality of life and cognition among the elderly in LTCFs.

VR exergame interventions among older adults living in long-term care facilities: A systematic review with Meta-analysis

BACKGROUND

To improve the motivation toward exercise in older adults, exergames have shifted from entertainment to rehabilitation.

OBJECTIVES

To review the training focus of exergames and analyze the effectiveness of exergame training on physical, psychological, or cognitive outcomes among older adults in long-term care facilities (LTCFs).

METHODS

This review followed the PRISMA guidelines. By searching 7 electronic databases up to April 30, 2022, studies were included if they 1) involved adults ≥65 years old residing in LTCFs, 2) were randomized controlled trials (RCTs) with virtual reality-based exergames as the intervention, 3) compared the effects of exergames to usual care or conventional exercises, and 4) reported physical, psychological, or cognitive outcomes. The Cochrane Risk-of-Bias tool for randomized trials version 2 (RoB 2) and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) were used to evaluate the methodological quality of studies and levels of evidence for outcomes. The meta-analysis was conducted with Review Manager 5.4. Results are presented as standardized mean differences (SMDs) and 95% confidence intervals (CIs).

RESULTS

A total of 12 RCTs were included in the systematic review and meta-analysis. For overall methodological quality, 10 studies showed some concerns and 2 studies showed high risk. Levels of evidence for outcomes were assessed as low (n = 8) and very low (n = 4). The studies involved a total of 482 older adults. Most studies implemented balance exercise as the exergame intervention. Older adults who completed exergame interventions showed improvements in cognitive outcomes (SMD 0.90, 95%CI 0.61-1.19, p<0.001) and in balance self-efficacy (SMD 1.04, 95%CI 0.47-1.61, p<0.001) as compared with those in usual care. They also showed improvements in balance (SMD 0.49, 95%CI 0.20-0.78, p<0.001) as compared with those in conventional exercise programs. Overall, exergames had a positive effect on balance (SMD 0.62, 95%CI 0.29-0.95, p<0.001).

CONCLUSION

This review revealed that exergames can improve the balance ability of older adults in LTCFs.

The effect of exergaming on cognition and brain activity in older adults: A motor- related cortical potential study

Exergames have positive effects on various cognitive domains. However, to the best of our knowledge, not only have few studies investigated the exergame-induced brain changes, but also in most of them, preparatory brain activity has not been considered. Preparatory brain activity is a particularly relevant aspect for investigating the interaction between cognitive and sensorimotor functions in the brain. Accordingly, the aim of this study was to investigate the effects of an exergame protocol versus traditional motor-cognitive dual-task training on the cognition and proactive components of movement-related cortical potential. A total of 52 older adults were randomly assigned to the intervention (exergame training) and the control group (motor-cognitive dual-task training). The outcome measurements were neurophysiological data (i.e., the amplitude of the late contingent negative variation [CNV], and alpha/beta event-related desynchronization [ERD]), and neuropsychological data (rate-correct score [RCS] in go/no go task and trail-making test [TMT]). The results revealed that both groups had a decreased late CNV, and alpha/ beta ERD in post-training compared to pre-training in Cz and C3 channels. Moreover, both groups had an increased RCS and a decreased TMT-A in post-training compared to pre-training. However, for TMT-B, the results indicated a significant interaction in favor of the exergame group. These findings indicate that in older adults, both interventions may result in increasing inhibitory control, information processing speed, and preparatory brain activity. However, for cognitive flexibility, exergame has an additional effect relative to the control group.

Virtual Reality Game for Physical and Emotional Rehabilitation of Landmine Victims

Landmine victims require an engaging and immersive rehabilitation process to maintain motivation and therapeutic adherence, such as virtual reality games. This paper proposes a virtual reality exercise game called Exogames, which works with Nukawa, a lower limb rehabilitation robot (LLRR). Together, they constitute the general Kina system. The design and development process of Exogames is reported, as well as the evaluation of its potential for physical and emotional rehabilitation. In an initial survey designed ad-hoc, 13 health professionals evaluated compliance with various requirements. They agreed that Exogames would help the user focus on rehabilitation by providing motivation; 92.3% said that the user will feel safe in the virtual world, 66.7% of them agreed or totally agreed that it presents characteristics that may enhance the physical rehabilitation of lower limbs for amputees, 83.3% stated that it would promote the welfare of landmine victims, and 76.9% responded that the graphical interface and data report are useful for real-time assessment, and would be helpful for four interventional areas in all rehabilitation stages. In a second evaluation, using standardized surveys, five physical therapists and one lower limb amputee tried the Kina system as users. They filled out the System Usability Scale (SUS), the Physical Activity Enjoyment Scale (PACES), and the Game Experience Questionnaire (GEQ). The usability of the Kina system overall score was 69 (66, 79) out of 100, suggesting an acceptable though improvable usability. The overall PACES score of 110 (108, 112) out of 126 suggests that users enjoyed the game well. Finally, users indicated a positive effect with a good sense of immersion and smooth of gameplay during the tests, as indicated by the GEQ results. In summary, the evaluations showed that Exogames has the potential to be used as a virtual reality game for the physical and emotional rehabilitation of landmine victims.

The Effects of Combined Physical and Cognitive Interventions on Direct and Indirect Fall Outcomes for the Elderly with Mild Cognitive Impairment: A Systematic Review

This review was intended to determine the effectiveness of physical and cognitive training (PCT) on falls and fall-related factors and cognitive function among community-dwelling elderly people with mild cognitive impairment (MCI). A systematic literature search was performed of the MEDLINE, CINAHL, Web of Sciences, Scopus, ProQuest, Embase, and Google Scholar databases for articles published from 2010 to 2020. The studies that combined PCT to assess their impacts on fall outcomes both directly and indirectly were included. Study quality was assessed using the standardized JBI Critical Appraisal Tool for RCTs. The standardized data extraction tool from JBI-MAStARI was used to extract data of included studies. Seven RCTs involving 740 participants were included. The overall fall incidence did not significantly decrease after the interventions. However, PCT significantly impacted the cognitive function and physical activities of elderly people with MCI, particularly improving their balancing ability, gait speed, muscular strength, and executive functions. This study indicated that combining PCT improves balance ability, gait speed, and executive functioning in the elderly with MCI, which may help to minimize fall occurrence.

Effects of exergaming on executive function of older adults: a systematic review and meta-analysis

Background

Executive function (EF) involves a series of high-level processes, such as inhibition, switching, and updating. Aging-related cognitive decline has been shown to be strongly associated with EF worsening. The aims of this study were to perform a meta-analysis to evaluate the effects of exergaming, an emerging intervention, on EF performance in older adults and to conduct a moderator analysis of exergaming effects on EF.

Methods

Randomized controlled trials examining exergaming influences on EF in older adults were collated by searching the Web of Science, Elsevier Science, PubMed, and Google Scholar databases. Statistical data were quantified in Comprehensive Meta-analysis software. Overall EF and EF domains (inhibition, switching, and updating) were analyzed separately.

Results

A total of 15 studies were included. The meta-analysis results indicated that exergaming had a significant influence on overall EF in the older adult (standardized mean difference (SMD) = 0.349, 95% confidence interval (CI) [0.191-0.506], p < 0.001). The same effects were also found in EF domains of inhibition (SMD = 0.415, 95% CI [0.102-0.729], p = 0.009), switching (SMD = 0.243, 95% CI [0.071-0.415], p = 0.005), and updating (SMD = 0.366, 95% CI [0.140-0.592], p = 0.002). The effects of exergaming on overall EF were found to be moderated by the frequency of the intervention (Q₍₁₎ = 3.537, p = 0.06).

Conclusion

Exergaming was confirmed to improve overall EF, as well as in older adults, and the effect of exergaming on EF was shown to be moderated by intervention frequency.

Comparison between the effects of exergame intervention and traditional physical training on improving balance and fall prevention in healthy older adults: a systematic review and meta-analysis

OBJECTIVE

Physical training (PT, e.g., Tai Chi and strength training) has been demonstrated to improve balance control and prevent falls. Recently, exergame intervention (EI) has emerged to prevent falls by enhancing both physical and cognitive functions in older adults. Therefore, we aim to quantitatively assess and compare the effects of PT and EI on the performance of balance control and fall prevention in healthy older adults via meta-analysis.

METHODS

A search strategy based on the PICOS principle was used to find the publication in the databases of PubMed, EMBASE, Web of Science, Cochrane Library, and MEDLINE. The quality and risk of bias in the studies were independently assessed by two researchers.

RESULTS

Twenty studies consisting of 845 participants were included. Results suggested that as compared to PT, EI induced greater improvement in postural control (sway path length, SMD = - 0.66, 95% CI - 0.91 to - 0.41, P < 0.001, I2 = 0%; sway speed, SMD = - 0.49, 95% CI - 0.71 to - 0.27, P < 0.001, I2 = 42%) and dynamic balance (SMD = - 0.19, 95% CI - 0.35 to - 0.03, P = 0.02, I2 = 0%) in healthy older adults. The EI with 90-119 min/week for more than 8-week significantly reduced falls. Subgroup analyses revealed that exergames, which were designed by the two principles of repeatedly performing diversified tasks and gradually increase the difficulty of the task, induced significant effects in improving balance control and falls prevention respectively (P = 0.03, P = 0.009). In addition, intervention that combines EI and PT induced significant improvement in postural control (P = 0.003).

CONCLUSION

The exergame intervention, especially the combination of EI and PT, is a promising strategy to improve balance control and reduce falls in healthy older adults. Future studies with rigorous design, larger sample size, and follow-up assessments are needed to further assess the effectiveness of diverse exergame interventions in fall prevention and to quantify the "dose-effect" relationship, as well as the carry-over effect of such intervention, which will ultimately help optimize the rehabilitative strategies to improve balance control and prevent falls.

Feasibility and Enjoyment of Exercise Video Games in Older Adults

Introduction: Several interventions have been developed to enhance social connectedness among older adults. However, little research has demonstrated their performance in a social distancing environment. Exergames are not only beneficial to older adults' physical and cognitive health, but they also allow players to interact with each other at a distance, which can reduce loneliness and increase social connection. The aim of this pilot study was to investigate older adults' perceptions of two commercially available exergames.

Methods: Twenty healthy community-dwelling older adults (M age = 73.30, SD = 5.95, range = 65–84 years, 80% women) were recruited in this pilot study between July 2019 and February 2020. They were asked to play two exergames for 10 min each on the Xbox One with Kinect console: Just Dance and Kinect Sports Rivals. After gameplay, they provided both quantitative and qualitative feedback on these games.

Results: Participants reported an average rating for exergame enjoyment. Greater enjoyment was significantly related with younger age and greater extraversion but not gender. Participants were highly motivated to do well on the games but reported lower scores for likelihood of playing these games in the future. Greater likelihood of future play was associated with younger age but not gender or extraversion. “Not aerobic or strengthen enough; not enough exertion,” and “slower movements, repetition, clear purpose of doing the exercise” were some factors that would influence their decision to buy and play these games.

Discussion: The preliminary results of this pilot study suggest that exergames may help address social isolation and loneliness—particularly during times of social distancing. Before applying exergames as a social isolation or loneliness intervention for older adults, study replication in larger representative studies and future work that examines important design issues related to older adults' experiences with these games is needed.

Exergame training-induced neuroplasticity and cognitive improvement in institutionalized older adults: A preliminary investigation

BACKGROUND

Prior research has reported cognitive improvements in elderly individuals when mental and physical exercise are practiced simultaneously, as in exergaming. However, the molecular mechanisms driving this beneficial response remain unclear. Moreover, there is robust evidence that regular exercise increases neurotrophic factors and promotes neuroplasticity, contributing to cognitive improvement. This research aimed to assess the impact of a 6-week Xbox 360 Kinect exergame protocol on cognitive function and brain-derived neurotrophic factor (BDNF) levels in institutionalized older individuals.

METHODS

Participants living in a long-term care facility were included. The intervention (Xbox 360 Kinect exergame protocol) was conducted individually and consisted of two sessions per week (40 min each) over 6 weeks. Participants' cognitive function (Montreal Cognitive Assessment, MoCA) was evaluated before and after the intervention. Blood samples (15 ml) were collected at the same time to measure BDNF levels.

RESULTS

Although there were no changes in total MoCA scores, exergame training improved the "language" domain and demonstrated a tendency toward an improvement in the "abstraction" and "memory/delayed recall" domains. Furthermore, BDNF levels were significantly increased after the intervention.

CONCLUSION

BDNF enhancement might mediate, at least in part, the cognitive changes induced by a 6-week Xbox 360 Kinect exergame protocol in institutionalized older adults.

Methodological Quality of User-Centered Usability Evaluation of Ambient Assisted Living Solutions: A Systematic Literature Review

This study aimed to determine the methodological quality of user-centered usability evaluation of Ambient Assisted Living (AAL) solutions by (i) identifying the characteristics of the AAL studies reporting on user-centered usability evaluation, (ii) systematizing the methods, procedures and instruments being used, and (iii) verifying if there is evidence of a common understanding on methods, procedures, and instruments for user-centered usability evaluation. An electronic search was conducted on Web of Science, Scopus, and IEEE Xplore databases, combining relevant keywords. Then, titles and abstracts were screened against inclusion and exclusion criteria, and the full texts of the eligible studies were retrieved and screened for inclusion. A total of 44 studies were included. The results show a great heterogeneity of methods, procedures, and instruments to evaluate the usability of AAL solutions and, in general, the researchers fail to consider and report relevant methodological aspects. Guidelines and instruments to assess the quality of the studies might help improving the experimental design and reporting of studies on user-centered usability evaluation of AAL solutions.

Meta-analysis of the effects of game types and devices on older adults-video game interaction: Implications for video game training on cognition

Video game training can effectively improve the cognition of older adults. However, whether video game types and game devices influence the training effects of video games remains controversial. This meta-analysis aimed to access and evaluate the effects of video game types and game devices in video game training on the cognition of older adults. Interestingly, results indicated that mouse/keyboard was superior over other video game devices on perceptual-motor function. The effect size (Hedge's g) for perceptual-motor function decreased by 1.777 and 1.722 when the video game training device changed from mouse/keyboard to driving simulator and motion controller. The effects of cognitive training game and conventional video game were moderated by session length. More well-designed studies are required to clarify the unique efficacy of video game types and devices for older adults with video game training.

Effects of Exergame-Based Dual-Task Training on Executive Function and Dual-Task Performance in Community-Dwelling Older People: A Randomized-Controlled Trial

Objective: Aging is associated with decline in executive function that may lead to reduced dual-task performance. Regular exercise has been recommended for promoting or maintaining mental and physical health in older adults, yet only a fraction of older adults exercise regularly. Exergame training may have the potential to enhance exercise adherence. Therefore, the aim of this study was to examine the effects of exergame-based dual-task training on executive function and dual-task performance in community-dwelling older adults. Materials and Methods: This was a single-blinded, randomized-controlled trial. Twenty community-dwelling older adults were recruited and randomly assigned to one of two groups. All participants completed 36 trainings, including three 60-minute sessions/week over 12 weeks. Participants in the experimental group received exergame-based dual-task training, while those in the control group received home-based multicomponent exercise training. Measures of executive function, dual-task performance, and community walking ability were assessed before and after the intervention. Results: Significant group × time interactions (P = 0.000-0.027) with large effects were found in all selected outcome measures. Compared with the control group, the experimental group improved significantly in measures of general executive function (P = 0.014), inhibitory control (P = 0.037), cognitive dual-task performance (P < 0.001), and community walking ability (P = 0.002). Enhanced general executive function was highly correlated with either improved motor dual-task performance (r = 0.674) or improved cognitive dual-task performance (r = -0.701). Conclusion: These results suggested that exergame-based dual-task training improved both executive function and dual-task performance in older people. These positive effects could be transferred to enhance community walking ability. Clinical Trial Registration number: ACTRN 12617000095369.

Exergames to Prevent the Secondary Functional Deterioration of Older Adults during Hospitalization and Isolation Periods during the COVID-19 Pandemic

The COVID-19 pandemic is having an intense impact on the functional capacity of older adults, making them more vulnerable to frailty and dependency. The development of preventive and rehabilitative measures which counteract the consequences of confinement or hospitalization is an urgent need. Exergaming can promote physical activity, prevent falls, and maintain functional and cognitive capacity. However, although the use of exergames in health programs for the elderly is promising, their widespread use should not be considered without the supervision of a social health professional. Therefore, the objective of this work was to evaluate and analyze three video game consoles (Nintendo Wii®, Xbox-Kinect® and Play Station 4®) and 26 commercial exergames with the aim of identifying their usefulness for the prevention of functional deterioration. Three occupational therapists analyzed the data independently, and subsequently agreed on the results. The examination of the commercial consoles met three criteria: components, interaction channels and the type of the exergame. Each exergame was analyzed taking into account its ability to train postural control, balance, upper limb functionality and cognitive function. The results of the evaluation showed that exergames contain game activities that can be part of the rehabilitative treatment aimed at the prevention of the functional impairment of older people affected by COVID.

Video game and motor-cognitive dual-task training could be suitable treatments to improve dual-task interference in older adults

The objective of study was to investigate the effects of video game training in comparison with traditional motor-cognitive dual-task training on dual-task interference in older adults. Sixty older adults were allocated to the video game (intervention group) or the motor-cognitive dual-task training (control group). The outcome measures were dual-task cost (DTC) of linear metrics (Standard deviation (SD) of amplitude and velocity) and DTC of nonlinear metrics (approximate entropy, Lyapunov and correlation dimension) acquired from postural sway time series from both the mediolateral (ML) and anteroposterior (AP) directions. The results revealed in both groups, dual-task cost of SD of amplitude and velocity as well as Lyapunov were significantly decreased in post-training and follow-up compared with pre-training (p < 0.017), while there was no significant difference between the groups. Video game and motor-cognitive dual-task training could be recommended as suitable treatments to improve dual-task interference.

The use of commercial computerised cognitive games in older adults: a meta-analysis

Brain training programs are currently one effective solution to prevent cognitive decline in healthy aging. We conducted a meta-analysis of randomized controlled trials assessing the use of commercially available computerised cognitive games to improve cognitive function in people aged above 60 years old without cognitive impairment. 1,543 participants from sixteen studies were included in the meta-analysis. Statistically significant improvements were observed for processing speed (SMD increased 0.40 [95% CI 0.20-0.60], p < 0.001), working memory (0.21 [95% CI 0.08-0.34], p = 0.001), executive function (0.21 [95% CI 0.06-0.35], p = 0.006), and for verbal memory (0.12 [95% CI 0.01-0.24, p = 0.031), but not for attention or visuospatial abilities. No relationship between the age of the participants and the amount of training was found. Commercially available computerised cognitive games are effective in improving cognitive function in participants without cognitive impairment aged over 60 years.

Evaluating a Novel Multifactorial Falls Prevention Activity Programme for Community-Dwelling Older People After Stroke: A Mixed-Method Feasibility Study

Purpose

The overall purpose of this study was to explore participants’ and physiotherapists’ experiences regarding the acceptability, implementation, and practicality of a novel group-based multifactorial falls prevention activity programme for community-dwelling older people after stroke. Specifically, the purpose was to explore if and how participating could impact on the participants’ health-related quality of life (HRQoL) in terms of their daily lived experience regarding physical, mental, emotional and social well-being. A secondary purpose was to explore whether participating in the programme could positively influence participants’ balance, strength, falls efficacy, mobility and motor impairment of the trunk.

Materials and Methods

This was an exploratory mixed-method Phase I feasibility study. A convenience sample of five older community-dwelling people after stroke participated in a novel eight-week multifactorial activity programme which included falls education, a mix of individually tailored and group-based strength and balance exercises, exploring limits of stability and safe landing techniques and a social element. Qualitative data from post-intervention interview transcripts with the participants and the physiotherapists who delivered the programme were thematically analysed using both deductive and inductive approaches to explore the participants’ and therapists’ experiences with the programme. Quantitative outcomes included balance, strength, falls efficacy, mobility and motor impairment of the trunk.

Results

The programme was deemed feasible in terms of acceptability, implementation and practicality by the participants as well as the physiotherapists delivering the programme. The overarching theme regarding HRQoL identified that participating in the programme was perceived to empower the participants living with stroke and positively influenced their daily physical, mental, emotional and social well-being. Participant outcomes showed a change in the direction of improvements in balance, strength, mobility, motor impairment of the trunk and reduced concerns about falling. Subjectively, participants only reported perceived improvements in balance and strength.

Conclusion

Running a novel multifactorial falls prevention activity programme for older community-dwelling people after stroke was feasible. Participating in the programme helped participants to perceive improved balance, strength and empower them to make meaningful changes, improving their daily lived experiences. A future fully powered study could build on these results to investigate physical improvements, prevention of falls and improvements to domains of HRQoOL.

Novel Mat Exergaming to Improve the Physical Performance, Cognitive Function, and Dual-Task Walking and Decrease the Fall Risk of Community-Dwelling Older Adults

Physical exercise and cognitive training were previously demonstrated to improve the physical functioning and decrease the incidence of falls for older adults. This study aimed to utilize an interactive exergame mat system to develop a novel cognitive–physical training program and explore the training effects on physical performance, cognitive function, dual-task walking (DTW), and fall risk compared to the control condition. In this quasi-experimental non-randomized controlled intervention study, 110 community-dwelling older adults participated. The exercise group (n = 56; mean age, 70.7 ± 4.6 years) performed ladder-type, three-by-three grid-type, and circle-type mat exergames with simultaneous cognitive–physical training (EMAT), while the control group (n = 54; mean age, 72.0 ± 5.7 years) underwent a multicomponent exercise intervention focused on physical and cognitive training. A 2 h training session was completed weekly for 3 months. Functional fitness (including upper- and lower-extremity strength and flexibility, grasp strength, aerobic endurance, static balance, dynamic balance and agility), a foot tapping test (FTT), the Montreal Cognitive Assessment (MoCA), DTW, and a fall risk questionnaire (FRQ) were assessed before and after the interventions. The EMAT program enhanced upper-extremity strength, lower-extremity strength and flexibility, aerobic endurance, and dynamic balance and agility; improved DTW and FTT performances; and decreased FRQ score. EMAT also showed a significant advantage over control in terms of lower-extremity strength and flexibility, aerobic endurance, dynamic balance and agility, and FRQ score (all P < 0.05). The current study provides evidence of the effects of a novel mat exergaming program on physical and cognitive performance. EMAT effectively reduced the fall risk and increased the dual-task ability of walking, factors that are important in fall prevention for community-dwelling older adults.

Effects of an In-home Multicomponent Exergame Training on Physical Functions, Cognition, and Brain Volume of Older Adults: A Randomized Controlled Trial

Aging is associated with a decline in physical functions, cognition and brain structure. Considering that human life is based on an inseparable physical-cognitive interplay, combined physical-cognitive training through exergames is a promising approach to counteract age-related impairments. The aim of this study was to assess the effects of an in-home multicomponent exergame training on [i] physical and cognitive functions and [ii] brain volume of older adults compared to a usual care control group. Thirty-seven healthy and independently living older adults aged 65 years and older were randomly assigned to an intervention (exergame training) or a control (usual care) group. Over 16 weeks, the participants of the intervention group absolved three home-based exergame sessions per week (à 30–40 min) including Tai Chi-inspired exercises, dancing and step-based cognitive games. The control participants continued with their normal daily living. Pre- and post-measurements included assessments of physical (gait parameters, functional muscle strength, balance, aerobic endurance) and cognitive (processing speed, short-term attention span, working memory, inhibition, mental flexibility) functions. T1-weighted magnetic resonance imaging was conducted to assess brain volume. Thirty-one participants (mean age = 73.9 ± 6.4 years, range = 65–90 years, 16 female) completed the study. Inhibition and working memory significantly improved post-intervention in favor of the intervention group [inhibition: F₍₁₎ = 2.537, p = 0.046, np2 = 0.11, working memory: F₍₁₎ = 5.872, p = 0.015, np2 = 0.02]. Two measures of short-term attentional span showed improvements after training in favor of the control group [F₍₁₎ = 4.309, p = 0.038, np2 = 0.03, F₍₁₎ = 8.504, p = 0.004, np2 = 0.04]. No significant training effects were evident for physical functions or brain volume. Both groups exhibited a significant decrease in gray matter volume of frontal areas and the hippocampus over time. The findings indicate a positive influence of exergame training on executive functioning. No improvements in physical functions or brain volume were evident in this study. Better adapted individualized training challenge and a longer training period are suggested. Further studies are needed that assess training-related structural brain plasticity and its effect on performance, daily life functioning and healthy aging.
